Mozilla has uploaded the stable version of Firefox 10 to its ftp server. The company is currently in the process of distributing the release to all of its world wide mirror servers in preparation for the release later today. The release of the extended support release version marks the beginning of the end for Firefox's 3.x branch which will be retired from support in April of this year.

The ESR release has been designed for companies, organizations and users who cannot keep up with deploying new Firefox versions every six weeks. Firefox ESR releases will follow the rapid release process, but increase only by a minor version whenever the standard version increases by a major version. Regular Firefox 10 users will be moved to Firefox 11 in six weeks time, while Firefox 10 ESR users will be moved to Firefox 10.1 instead.

The ESR release will be offered separately from the regular version of Firefox. Also, unlike in regular versions of Firefox, Firefox ESR updates add security and stability fixes only. That's a stark contrast to Firefox Stable releases which get new feature updates as well with every release.

This means that ESR is more stable in regards to functionality which is a good thing for organizations and users who want or require more stability when it comes to the release process and updates.

Another important change in Firefox 10 is that add-ons are now automatically set to be compatible if they have also been compatible with Firefox 4. This ends the majority of the add-on compatibility issues that Firefox users experienced whenever a new major version of the browser was released.

The beta changelog lists the features one expects from a six week release cycle with the new hidden forward button the most notable change. Firefox 10 furthermore adds support for CSS3 3D-Transforms, anti-aliasing for WebGL, full screen APIs that can be used to build web apps that run full screen and support for the bdi element for bi-directional text isolation.

Developers can make use of the new CSS Style Inspector and IndexedDB APIs that match the specifications more closely

The previously announced silent update option has not made it into this version of Firefox. Mozilla aims to release the new feature with Firefox 13, which is expected to launch in the beginning of June.

Firefox users can expect to see update notifications later today. Please check out our Firefox 10 What's New guide which looked at the changes in the Firefox 10 Aurora version.

Update: Firefox 10 Stable (here) is now available at the official Mozilla website.

    I am so sick & fed up with Firefox updating every time I turn around, making me have to go to the bother of manually updating many of my add-ons. There are some add-ons out there that still work on current versions of Firefox but Firefox, nonetheless, says they’re incompatible with current versions of it due to the original creator of the add-on not actively developing that add-on. BTW, it’s simple to manually update your Firefox add-ons if you so wish to. Just change the extension of the add-on from .xpi to .zip. Then, unzip the newly created .zip file & open the newly created folder. Inside the folder, there should be an install.rdf file. Open that up in notepad or whatever text editor you use. To bump up the version compatibility, change the version number that is between & , then save the changes to the file & close it. Now, while still in the folder, open up the Terminal and type – “7za a -tzip myextension.xpi chrome install.rdf install.js -r -mx9” Of course, change ‘chrome,’ ‘install.js,’ etc. to whatever the folder contents may be. Now, open the add-on in Firefox to install it. Wha-la! You have a bumped-up version of that add-on running in your Firefox!

    I clicked the link to get stable version 10. Firefox didn’t have it available on their download list. I am in 10 and want to stay there. I disabled the update function, so far, I’ve blocked the Firefox updating my Firefox with the version 11. Is it possible for an individual to get into the stable ESR release cycle as I hate the new Firefox cycle? It says it is for organizations or businesses only.

    My RoboForm is still there on the tool bar and working with 10.0 , although the update said it wouldn’t.

    Version 10.0 is not automatically compatible with all extensions.
    Tab Utilities 1.1.2 is Disabled under 10.0, worked with all previous versions. Firefox says it is incompatible with Firefox 10.0.

      After the Deadline spelling extension does not work as well in Firefox 10.

    ESR, What a stupid move. Version numbers doesn’t mean a thing, specially when all add-ons are now automatically compatible.

    Thank you for the link! I downloaded Firefox 10 ESR [en-GB] for Windows just fine. It should suffice for now; however, I believe Mozilla will come up with a separate page for the ESR users.

    Is pretty much the closest thing you can get at the moment.

    1. Martin Brinkmann said on January 31, 2012 at 4:03 pm

      There is one in the release directory as well.

  9. Sid said on January 31, 2012 at 2:23 pm

    Hi Martin.
    Can you please provide the links from where one can get hold of the ESR release for Firefox 10?

    1. Guest said on January 31, 2012 at 9:47 pm

      All ESR versions are here at the bottom of the page.
