Mozilla has released yet another beta for Firefox 3.6, this is the third beta meaning the RC is at hand, this beta fixes more than 80 bugs and much more stable and the improved JavaScript engine does a good job in rendering but the 3.6 is marginally faster than 3.5 I hope this will change in 3.7.
If you are using 3.6 beta 1 or 3.6 beta 2 I advise you to upgrade ASAP. Incompatible plugins are always an issue, but you can always disable compatibility checking by following this guide, but Its better you install Mozilla’s Add-on Compatibility Reporter add-on and tell Mozilla if your favorite add-ons work with the new Firefox release. This add-on disables compatibility check as well.
I have checked and I’m confirming that Firefox 3.6 Beta 3 DOES NOT break the following extensions:
LastPass
Xmarks
Greasemonkey
Ad Block Plus
Ad Block Plus Element Hiding Helper
Download Firefox 3.6 Beta 3 – English
Download Firefox 3.6 Beta 3 – All Language



for me.more important is Google Preview
Seems that the Beta 3 is incompatible with Glasser.
Or at least only failed on my PC only…
