Mozilla has once again released a new version of Firefox a few hours early on its FTP servers. Firefox 25 is now available for download for Windows, Mac and Linux from that location, but will likely launch the latest public build of the web browser on Tuesday via the automatic update feature or on Firefox.com. The Android version of Firefox 25 will also likely become available on Google Play on Tuesday as well.
The FTP download does not have an official change log but the beta versions release notes states that Firefox 25s find bar is no longer shared between tabs. It also states that "Resetting Firefox no longer clears your browsing session" and a new option to "migrate another browsers history and settings" if a user has not access Firefox recently. Its more than possible that the final version of Firefox 25 will have even more new features.
Earlier today, Mozilla confirmed to Neowin that it will continue to support Firefox when used on Microsofts 12 year old Windows XP operating system for the foreseeable future. We are still awaiting when the version of Firefox that works with the Modern UI of Windows 8 and 8.1 will come out of beta testing. At the moment, it looks like that will happen with Firefox 27, which is due for release in January.
