The latest stable version of the Firefox browser has been released yesterday by Mozilla. We have reviewed Firefox 9 a day before the official release to inform users about the changes, and to provide everyone with links to download the version a day early.

A new version of Firefox appeared on the official Mozilla ftp server today, only a day after the release of Firefox 9. News about the release of Firefox 9.0.1 are scarce at the moment.

The only indicator is a critical bug listing on Bugzilla that was likely the cause for the rushed new version. Bug 712490, Tracking bug for build and release of Firefox 9.0.1, does not reveal additional information about the nature of the bug. The only information to gather from the bug listing is that it affects all Firefox platforms and versions.

Bugzilla lists one additional bug with a normal severity rating which makes it very unlikely that it has been the cause for the rushed release. The bug is preventing custom app updates on Linux versions of the Firefox web browser.

firefox 9.0.1

Firefox 9.0.1 is currently being distributed to Mozilla ftp servers and the distribution network. It is likely that Firefox 8, Firefox 8.0.1 and Firefox 9.0 users will receive update notifications in the next 24 hours.

The Mozilla website is currently listing Firefox 9.0 as the latest web browser version on the Get Firefox download page. Release notes and bug fix pages for Firefox 9.0.1 have just been created. They are however currently displaying a copy of the Firefox 9.0 release notes and bug fixes.

It is likely that the information will get updated in the next hours. Firefox users who are experiencing issues in the browser may want to go ahead and download version 9.0.1 early to see if the new release resolves the issues.

Everyone else is probably better off waiting for the official release announcement which hopefully will provide additional information on the issue. (Thanks Midnight for the tip)

    So, it appears 9.0.1 “fixes” anyone’s best guess. :) At best, I am now convinced based on its history, one needs to blow off any x.0 release and just wait a day or two for x.0.1. I’m thinking of starting an office pool in our IT dept. where the winner selected the date/time closest to the announcement of the x.0.1 release.

    Although I never had any crashes, I always like to keep my software up to date and when I saw this fast, new release, I installed 9.01.

    Glad to know that others are aware of the bug(s) fixes and are updating as well. :)

    I had 4 crashes in less than 2 days since updating to the new version so I hope this update will fix that cause I hadn’t had a Firefox crash in like years.

    It was a crash that was primarily affecting OS X users, but was applicable to all platforms.

    Bug 335998 was an issue with getParentNode not working. A fix was made and committed.

    That fix caused noticeable cycle collector (CC) delays, which was reported as Bug 702813.

    As a fix for the delays, it was suggested to back out the original fix from 9.0. This was Bug 708572.

    After 9.0 was released (with a “slow start” so that it was gradually offered as auto-update), Bug 711794 was reported which involves crashes. That report details how the investigation led back to 708572. So they made 9.0.1 with 708572 backed out which was itself a backout, i.e. they put the original 335998 fix back in and are going to just live with the CC delays until they can definitively track down the real cause.

    It was not a security/crash fix.
    It was a hastily bug back out of the following bug:

    I believe it’s a bug related to the tabs. You could have closed the only tab open, and still navigate to different sites by clicking on a bookmark, and the tab will stay closed

      You could get it on the ftp or be patient and wait for it to hit the updater.
      Nobody can possibly be that impatient!
