Firefox 61.0.2 release information

Mozilla released a new version of the organization's Firefox web browser to the release channel on August 8, 2018.

Firefox 61.0.2 is a bug fix release for the most part but it introduces a new feature on Windows as well.

Firefox users who run the a release channel version of the web browser can use the browser's automatic update functionality to download and install the new version.

Just select Menu > Help > About Firefox to run a manual check for updates. Firefox should pick up the new version automatically and install it.

Firefox 61.0.2 is also available on the official Mozilla website for download if that is preferred.

Tip: Offline installers for Firefox are also available.

Firefox 61.0.2

Firefox includes a new feature on Windows that enables the automatic restoration of the Firefox session on Windows restarts. Mozilla has not enabled the functionality for all Firefox users on Windows but plans to roll it out gradually over the course of several weeks.

The feature is controlled by the preference toolkit.winRegisterApplicationRestart which you can modify manually to turn the new feature on or off as you see fit. While not mentioned explicitly by Mozilla, I think it is only available for Windows 10 and not previous versions of Windows.

  1. Load about:config?filter=toolkit.winRegisterApplicationRestart  in the Firefox address bar to get started.
  2. If you get a warning prompt confirm that you will be careful.
  3. Double-click on the preference.

A value of true means that the feature is enabled, a value of false that it is turned off. If set to true, Windows will load the Firefox session automatically if you shut down or restart Windows without closing Firefox prior to that.

Set it to false to disable the feature so that Windows won't start Firefox automatically on start if you did not terminate the program at the end of the last session.

Firefox 61.0.2 includes three additional changes:

  • Fixed a crash for users who have select accessibility tools enabled in the browser.
  • Certain extensions led to broken Developer Toolbar panels.
  • Retained Display List feature enabled to improve website rendering.

You can check out the full release notes here. You may also want to check out our Firefox 61.0.1 and Firefox 61.0 release overviews if you have not already.

Now You: What is your take on the session restore feature of Windows?

    The option to set cache size used to be in preferences have tried to rest to 75mb in config file but it reverts back to default.

    1. Tom Hawack said on August 12, 2018 at 9:18 am

      It’s true that Firefox no longer includes disk cache settings in its Preferences …

      Disk cache related about:config settings :
      In about:config search for : browser.cache.disk
      In urlbar type : about:config?filter=browser.cache.disk

      If you’ve modified manually settings in about:config but they revert when you restart Firefox then check in your Firefox profile for a user.js file which may contain the same settings you had modified manually.

      1. Jody Thornton said on August 26, 2018 at 1:56 am

        Can you still disable disk cache? Can you alter the same of memory cache?

    The automatic restore function seems reasonable for Windows 10, where (as I understand it), unplanned shutdowns and restarts are more frequent than in previous versions of Windows.

    1. owl said on August 12, 2018 at 12:39 am

      Fortunately, I have never experienced an unexpected Shutdown or Restart.
      Windows 10 Home (Japanese, 64 bit): 1803 (build: 17134.191)
      OS update is only “automatic update”. Set the active time.
      Security solution:
      Malwarebytes free, simplewall, Windows Firewall Control, Heimdal PRO, Reason Core Security free, AppCheck free

      For reference case,
      I am interested in Issues.

        Might wanna throw in 3 or 4 more AV software in there, doesn’t feel safe.

      2. Tom Hawack said on August 13, 2018 at 7:11 pm

        Depends of the AV, some are not sure at all.

  3. Steve said on August 11, 2018 at 1:37 am

    A couple of things regarding this update:
    – I don’t like the idea of an automatic restore, mainly because if it works like the current tab restore with “Save and Quit,” many times it restored the wrong web pages. Also there is the risk of resubmitting info at certain sites.
    – Did anybody notice the need for a restart upon updating using the offline installer? I wonder why. This never happened to me before.

    1. owl said on August 11, 2018 at 7:34 am

      Full text, same opinion.
      I am using beta version and Developer-Edition version.
      With this TOPIC, I learned that the automatic restoration function was activated.
      The automatic restoration function is convenient, but I think that “risk” will also be invited.
      Unexpected reboot or shutdown of the OS is rarely happening.
      Temporarily preservation will be done in a timely manner, and you will be in a measure by doing Backup.
      If it still occurred, I will give up “I was in bad luck”.
      For me, the automatic restoration function is not important.
      I have chosen “invalidate”.

      However, in the current end user situation (skill is unnecessary and emphasis on usability), I understand that it is a welcome function (automatic restoration).
      Mozilla provides services to unspecified majority (from children to the elderly, men and women). The viewpoint (product development) of “beginner user and entry user” which account for the majority of the end user layer is important. If this perspective is inadequate, Mozilla will not be able to survive in the industry because it will be abandoned from the main customer base.
      Therefore, adding this automatic restoration function is reasonable.

    that is a welcome surprise, it will obviate the need for user to restore their previous session manually and hopefully prevent previous sessions from being wiped out by accident, I had this issue with Chrome just a few days ago, the computer did not wake from it’s sleep state properly, when I went to restore the previous session I was working on in Chrome, it was nowhere to be found, I had to painstakingly scour through the browsers previous history just to restore some of the tabs I had open during that previous session, in my opinion, if a user had a previous session then it should ‘always’ be restored ‘automatically’, let the user have the responsibility of choosing whether to keep previous open tabs or not

    @Richard Allen – the proper term for the abbreviation UPS is ‘Uninterrupted’ Power Supply, we all make mistakes, there is no need to name call

    1. Tom Hawack said on August 11, 2018 at 6:51 pm

      Sounds like Russians trying to become perfect Americans :=)

    2. Richard Allen said on August 10, 2018 at 7:15 pm

      You’re right, we all make mistakes and I definitely make my share. As for the proper term (Uninterrupted or Uninterruptible) for the abbreviation UPS, the prevalent word used here in the Wild West is more often than not “Uninterruptible” but I have seen both used. You say tomawtoe I say tomaytoe and either way the idea gets across. :)

      > there is no need to name call

      Well, he was calling *himself* out. Also, maroon is a lovely color :)

      1. Richard Allen said on August 10, 2018 at 7:19 pm

        Thank You Sir/Ma’am/Miss/Ms/Mx/My Lord/My Lady. LoL. Finally, someone that actually gets my lame attempts at humour!
        The unanswered question will forever remain so, will it not? :)

        Hopefully some of the French speaking anonymous visitors to gHacks can appreciate that the quote “What a maroon”, which is from my animated hero Mr. Bugs Bunny, is a double entendre, regardless of how bad a translation that might be (double entrende). “Maroon” is a shade of red and red is often seen when people are embarrassed and maroon is also a play on the word moron. Anyway…

        “Shhh. Be vewy, vewy quiet.” > “I’m hunting wabbits.” – Sir Elmer Fudd

      2. Tom Hawack said on August 10, 2018 at 8:38 pm

        “double entendre” would be “à deux sens” : “Le mot maroon est à double sens” (“The word maroon has a double meaning” … “c’est un jeu de mots” (“it’s a word game” [or “pun” tells me Deep Translator]).

        This said, I finally know what ‘maroon’ means, an embarrassed bunny :=)

        Richard, you write “Hopefully some of the French speaking anonymous visitors to gHacks can appreciate that the quote “What a maroon”. I’m French and I’ve never this word elsewhere than here, but maybe have I missed latest developments of our language, lol

      3. Richard Allen said on August 11, 2018 at 12:29 am

        I’m sorry Tom, I could do a much better job remembering that gHacks has a surprising amount of global visitors. It’s actually pretty impressive and I love it, the diversity. I need to remember that my American cowboy slang and humour does Not often translate very well to those outside this country and for that I apologize!

        I think too often my intent is misconstrued. Which is why I often get long-winded with my comments trying to make sure that I am understood and then I still fail. C’est la vie!?! ;)

        Bugs Bunny, Elmer Fudd, Daffy Duck, Wile E. Coyote, Charlie Brown and many many others are animated cartoon characters from The Glory Days of hand-drawn animations. They all drastically went down in quality as artists got too expensive and computers replaced them. I think the early days were pretty incredible and funny as hell! And I’m personally very sad for everyone not familiar with those characters.

        Just some of my amusing background:
        I was born in München (Munich) and started school in Frankfurt. I’ve been to Germany, France, England, Mexico, Hong Kong, Guam, Okinawa, the Philippines and 49 of these 50 glorious United States, never made it to Alaska. I grew up speaking Spanglish/Deutsch, Spanish/English/German. Amusingly enough all in the same sentence. And I often needed my personal translator for others to understand me, I called her Mom. LoL. I’m not a real cattle ranch cowboy, more like an urban cowboy. I can sit a horse and ride the hell out of a mechanical bull, at least until I end up on my backside. I was raised in Colorado and my parents were born and raised in “The Republic of Texas” aka “Sovereign State of Texas” (American/Texan joke). I feel like I’m related to half of Dallas with relatives in Austin, Houston and San Antonio. Long story short – When I was a kid my grandparents owned a big cotton farm in south Texas and they had horses, cows, pigs, goats, chickens, you name it. I remember the first time I saw a chicken running around minus its head! That horrifyingly wild beast had escaped my grandmothers clutches. I know three little hooligans (me, myself and I) that were severely traumatized that day because the wild beast seemed to be chasing him all across God’s green earth. The Horror! LoL

        So… “Cowboy Up” mother******s! (American slang) Perception is not always reality. I learned that the hard way! :)

        @Richard Allen: And I’m personally very sad for every Frenchman not familiar with Pepé le Pew. In the French dub, he’s Pépé le Putois (Pépé the Skunk), he’s Italian, and he’s just not as funny — the voice talent and dialog just don’t rise to the level of the original. Also, you’re from Texas and *Bugs Bunny* is your hero? Not Foghorn Leghorn? I say, I say, I say, what’s *wrong* with you, son?

      5. Richard Allen said on August 11, 2018 at 6:22 pm

        @A different Martin
        Right you are sir! How could I forget Pepé le Pew? The Shame! And Foghorn Leghorn!!! I say, I say, I say, what IS wrong with me? LMAO

        Thank You for showing me the errors of my way! I have sadly failed yet again! ;)

      6. Tom Hawack said on August 11, 2018 at 9:30 am

        @Richard Allen, diversity! pluralism! that is the salt of life! I agree beyond my mind, from my very soul, I love it as well. This approach makes terms like “tolerance” insignificant because I am not to tolerate differences but to worship them given they are the source of humanism and at the same time of self-improvement.

        You’ve lived diversity far more than myself. Europe is my nest and America a six years’ fly away (1959-1965). Twelve years in Switzerland where I was born, two years or so in the Netherlands, touch ‘n’ goes in Germany, UK, Italy. As a child, previously to NY, I traveled with my parents in several countries where the U.S. had Army& Air Force bases (dad worked for the DoD as a civilian). I remember nevertheless Tripoli in Libya, Ramey AFB in Puerto Rico, the PX stores … “flashes” more than precise souvenirs … but all participating by their diversity to enrichment of my thoughts and construction of my mind.

        Diversity means identities, and respecting ours as those of others is a condition of valuable dialogs, the problem is never in diversity but arises when one considers his identity as superior, only. I appreciate that culture you share, I learn. Part of that culture you describe was mine even if six years as a kid in The States some fifty years ago is far less nourished by American culture than yours. I read your comments about Colorado, cow-boys & horses, the duality between your interest (love) for that life though tempered by your lives abroad (we never commit ourselves the same way when we have multiple experiences of the world). Texas is one State and one part of America many people know only by cliches. I visited my dad (last time I saw him as well) when he had retired in El Paso, in 1982. But I know nothing of Texas and so little of the USA to which I relate only via my memories of N.Y. fifty years ago, even if such an experience created a basis to better understand what I discovered and continue to discover of America through the ages.

        In N.Y. I attended moreover the United Nations International School (UNIS) with friends from all horizons be they ethnic, cultural, religious and citizenship : impossible with such a background to be “blocked” in the face of differences, those differences which have all contributed to what I am now.

        EOF, not EOLife :=)

      7. Richard Allen said on August 11, 2018 at 6:50 pm

        @Tom Hawack. Excellent!

        I truly believe this would be a better world if more people were able to travel and meet new people from different cultures and took the time to have a real conversation with those that have different ideas and values.

        I’m not talking about tolerance but about knowledge. There is more knowledge available today than ever before in history. But few would argue that people are wiser than ever before. Anymore, tolerance is a synonym for shut up and just accept what you don’t like and only applies to those with opposing ideas/values.

        Anyway… one of my favorite areas in this very large country that I’ve been fortunate enough to see is east Texas along the Gulf Coast. Also, St. Petersburg, Naples and Hollywood, Florida. San Diego and Seattle. Apparently I like water so west Texas (El Paso) does not make my top ten list but then anywhere along the Rocky Mountains does. Go figure! :)

      8. Tom Hawack said on August 11, 2018 at 7:14 pm

        @Richard Allen (August 11, 2018 at 6:50 pm), hard to say maybe what makes us fond of a place, several things perhaps, some objective and some subjective; and what makes us recall those places in good or bad terms. Social and relational life, environment, way of life. But memories sometimes don’t correspond to the way we loved or disliked places back then. I think time is a parameter among others in our own analysis of what we cherish or not. The present moment is always parasitized by ourselves. Without memory there is no intelligence, the past is always present in our approach of things when the future is not, which is why the real, the most essential and mysterious aspect of life is the future.

    “What is your take on the session restore feature of Windows?”

    If restoring sessions happens automatically, then I am opposed to it. If it’s in the form of a prompt asking if I want prior sessions restored, then I don’t have a problem with it.

  6. Richard Allen said on August 9, 2018 at 6:04 pm

    I’m currently using 62b15 on “Windows 7” and “toolkit.winRegisterApplicationRestart” is set to true. It’s also set to true in Nightly.

    I generally do not leave any applications running if I shut down or restart Windows so I’m going to leave the setting set to true, for now. And I use a UPC so power outages aren’t a problem. Until something comes along that is comparable to the Tab Mix Plus session restore I’m okay with “ApplicationRestart” being enabled but then I can’t imagine in my case that it will ever be used. We’ll see.

    I still Very Much Dislike the “New and Improved” preview image and favicon in the bookmark dialog so I finally got around to figuring out some css to remove it. I’m sure I won’t be the only one. Ugh. Why Mozilla why? :)
    #editBookmarkPanelImage, #editBookmarkPanelFavicon { display: none !important; }

    Depending on the new features coming up I will often temporarily update to the beta channel to see how things are working. So far 62 Beta is working very well.

    1. Richard Allen said on August 9, 2018 at 6:11 pm

      UPC should have been UPS (Uninterruptible power supply) — What a maroon!

      1. Richard Allen said on August 9, 2018 at 6:31 pm

        Today, this cowboy is failing miserably at multi-tasking. The default for “toolkit.winRegisterApplicationRestart” is true in both Beta and Nightly, on Windows 7. I didn’t make that clear.

  7. Yuliya said on August 9, 2018 at 8:46 am

    I don’t like the idea. I clearly want everything purged from RAM if I’m restarting my computer.

    1. Martin Brinkmann said on August 9, 2018 at 9:44 am

      You can make sure it is turned off using the instructions. Won’t kick in then.

      1. Tom Hawack said on August 9, 2018 at 10:52 am

        toolkit.winRegisterApplicationRestart is indeed false by default now here on Firefox 61.0.2, now and forever since I’ll enforce it to false in my profile’s user.js. But I can understand the feature may be appealing hence pertinent.

      2. Yuliya said on August 9, 2018 at 10:31 am

        Yeah, it’s disabled here right now. I’ll keep an eye on that setting in the upcoming updates to make sure it stays this way.

  8. Pierre said on August 9, 2018 at 8:17 am

    It is false by default

    1. Martin Brinkmann said on August 9, 2018 at 8:39 am

      For most users yes, but it will be enabled as far as I understood it for more users over the next weeks.

  9. Deo et Patriae said on August 9, 2018 at 8:12 am

    Is this why Firefox 62 beta for the first not placebo at all, starts almost instantly, like MS Edge? Preloads shite?

    1. Martin Brinkmann said on August 9, 2018 at 8:17 am

      I don’t know. The feature added to the release channel works only if you don’t close Firefox before you shut down or restart.
