The folks at Mozilla have released a new version, 3.6.10, of the Firefox browser for all platforms (Linux, Windows, and Mac OS X). This is described as a stability update that, according to the Release Notes, fixes “a single stability issue affecting a limited number of users”. Given that this release doesn’t include any security fixes, you don’t have to rush to install it — unless, of course, you are one of the “limited number of users”. (It is a good general policy to keep your software installations up to date, though.)
You can get the new version via the built-in update mechanism (main menu: Help / Check for Updates); you can also download a complete installation package (which will also update an existing installation) from the download page.
Update Friday, 17 September, 11:13 EDT
I’ve found a little more information on this update. Firefox 3.6.9 fixed several security vulnerabilities; one of the fixes unfortunately introduced a bug that caused instability in certain configurations. This version, 3.6.10, fixes that regression.
