It looks like the first half of December is going to be quite busy for Mozilla, with the open source browser vendor planning a range of releases.

Beta testers can now get a taste of the upcoming refreshes for Firefox 3.6.x and Firefox 3.5.x. The company recently made available for download the Candidate builds for Firefox 3.6.13 and Firefox 3.5.16, allowing early adopters to take the two updates out for a spin.

Firefox 3.6.13 and Firefox 3.5.16 are both nothing more than standard updates for the two predecessors of Firefox 4.0.

Mozilla is using the refreshes in order to introduce stability improvements, by fixing bugs, and patches, by resolving security issues identified in the current versions of Firefox 3.6 and Firefox 3.5.

As it is the case, Mozilla will only detail the changes that Firefox 3.6.13 and Firefox 3.5.16 bring to the table once the updates are already available for the public.

The browser vendor currently plans to have Firefox 3.6.13 and Firefox 3.5.16 launched in tandem by the end of next week, specifically on December 9th.

For the time being, testers will need to content themselves with the nightly builds of Firefox 3.6.13 and Firefox 3.5.16 releases on Mozilla’s FTP servers.

Of course, in addition to Firefox 3.6.13 and Firefox 3.5.16, Mozilla is also cooking the eight update to Firefox 4.0.

While the initial plan was to start serving Firefox 4.0 Beta 8 to early adopters by the end of November, Mozilla won’t actually be able to do it until the second week in December.

In this regard, the week of December 6th will most probably bring with it Firefox 4.0 Beta 8 and the confirmation that the project has been further delayed.

With Firefox 4.0 Beta 8 expected for next week, it’s highly unlikely that Mozilla will pull off another two Beta releases in December, which means that Beta 10 and even Beta 9 could clip into early 2011.
