Mozilla Firefox 7 Released

With the rapid release cycle and all, we are seeing more releases of the Firefox browser than before. Mozilla just pushed Firefox 7 to the official ftp server to prepare for today's release of the browser. Firefox 7 is actually the first version of the rapid release cycle that is showing big improvements over previous versions.

You may remember that both Firefox 5 and 6 did not ship with big new features or improvements. Well, this changes with the release of Firefox 7. When you look at the new features you will notice one sticking out: Mozilla managed to improve memory usage of the Firefox web browser drastically (that's the organization's word). What does it mean in detail? A blog post by Nicholas Nethercoate over at Mozilla has the answers:

Firefox 7 uses less memory than Firefox 6 (and 5 and 4): often 20% to 30% less, and sometimes as much as 50% less. In particular, Firefox 7′s memory usage will stay steady if you leave it running overnight, and it will free up more memory when you close many tabs.

Up to 50% less memory usage is a big number. Probably even more important than that is that the browser won't feel like eating up all the RAM over time anymore, which is definitely a good thing, considering that the browser has a reputation for being memory inefficient.

The changelog lists addition features, including a new rendering backend that speeds up Canvas operations on Windows, support for text-overflow: ellipsis and the Web Timing specification and faster bookmark and password changes syncing when using Firefox Sync.

Firefox 7 is currently not available on the official homepage. It is likely that the developers are still preparing for the new release. Some mirror servers are already listing Firefox 7 for all supported operating systems and languages, while others do not. Expect a release announcement in the next 24 hours.

Firefox stable users will receive update notifications shortly in the browser to update automatically to the new version.

Beta, Aurora and Nightly users will also be pushed to a new version in the coming days. Check out Future Firefox Features, What I’m Looking Forward To for some pointers as to what you can expect in those versions.

      Has Mozilla removed the bloated memory hog plugin-container.exe in Firefox 7 ?

        plugin-container isn’t a memoryhog, it prevents your entire browser from crashing…

        The plugin container prevents the browser from crashing when a plugin crashes. Firefox has no control over plugin-container’s memory usage.
        ALL of the memory usage plugin-container takes is due to the plugins it houses. If there was no plugin container, the memory allocated by plugins would be folded into the usage by firefox.exe.
        Thus, if plugin-container is taking up memory, blamer your plugins.

      An opera update is well overdue :) Both Chrome and Firefox have had at least 2 :)

      If Firefox fixed this bug, it will become a perfect browser:
      https://bugzilla.mozilla.org/show_bug.cgi?id=660577

      That is a big bug, I always afraid of opening webpage contain large amount of image with Firefox, with a webpage have >400 images with normal file size(800×600), Firefox will freeze.

      Well, after an hour or so, can’t see any great memory advantage to v7.I will continue to monitor it.

        I think Firefox just improves javascript memory performance, not image memory performance.

        But be patient, this problem will be fixed soon.

        Open this page, Firefox will freeze by image cache problem: http://www.clarosa.info/firefox/bug.html

          I thought the promise was simple RAM usage?? In any event,I don’t see any great advantage there. However, the browser is noticeably snappier,which I did not expect.

      Did notice that it was higher than before then i thought, oh! oh!
      there’s bound to be an addon who’s not quite ready for 7 so,
      i removed a few non essentials and yup, it went down down.

      Less memory consumption ???? Hmm … WHERE ???
      My Firefox 7 still uses 180-200 M from my RAM (and I only have 512 M on my system …)
      I don’t think that anything to do with the fact it’s not the stock firefox, but the OpenSuse 11.4 compiled variant……
      So, please, wouldn’t it be better if you don’t copy Microsoft’s way of lie to people with stuff that’s not really present in the software ????

      I’ve noticed that Adblock Plus is a real power hog.
      Without it, i get around 80M-100M (without more than 3 other addons).
      But after you’ve used for so long, it’s hard to do without.

        Ok, you can try this suit:
        + Replace AdBlock with SimpleBlock, Karma Blocker, these two extensions is faster and you will can’t notice about memory leak like AdBlock.
        + I recommended you to use FlashBlock, this extension save Firefox CPU Usage, also save RAM and it is a very small extension.

          Thanks for these alternatives Cattleya!

          Actually, i have about a dozen addons goin’ (one incompatible) and FF runs anywhere in between 135K-160K. I did remove a few a non-essentials and gradually testing but so far, it’s not really that bad.

          (Don’t like addons that remove flash but leave a space with a big letter).

      But you know, what gets me is the fact that Seamonkey uses about 80K on my system and it has an email client incorporated!

      Firefox 7.0.1 keeps wiping out my theme settings and switching to the default theme. It doesn’t matter what them I select… Very frustrating!!!
