Download All Versions of Mozilla Firefox 10 Here

Latest Videos FromTom's Hardware

Of note is that Firefox 10 is the first with an Extended Support Release (ESR) that will only make a major version jump every 42 weekss. The ESR version is meant for use by enterprises, public institutions, universities and other organizations so that they don't need to support a new version bump every six weeks in the normal release. The ESR version, however, will still receive all security-related updates.

When you upgrade Firefox, you need to delete your old saved files - cookies, cache, history (not bookmarks, they're fine). If you don't, you could have problems.

I found this out the hard way. Updated to Firefox 4, had trouble, read that I should delete those files, no more trouble. Worked like magic. :D

captaincharismai think i will give it a try. opera has been a big epic fail for me the past few monthsI use Opera on a daily basis, it has been the most stable and efficient out of the three browsers I use. Chrome often breaks down by crashing Flash or Shockwave, while Firefox is the slowest out of the three. Opera gets the work done quickly and easily.

I wish they would release a 64-bit version for windows. They have the Aurora and Nightly builds in an optional x64 version, why not keep the x64 for release versions aswell?

otacon72Wasn't it at version 4 a few months ago?...lol I'll give it a try until the flash plug-in crashes then it's back to IE.
Did you ever try updating your flash plugin? It's usually not the browser's fault if a plugin doesn't work.

I have the same problem with firefox crashing using flash, especially when switching to full screen, or from full screen. It is so hard to watch youtube with FF, it's faster, just unstable. Installed and uninstalled flash a dozen times, and it only happens with FF.

you can fix problems like this by backing up your bookmarks, uninstalling firefox and tellign it to remove all user preferences, then reinstall it fresh and restore bookmarks and reinstall any addons.

i'll get firefox once the rendering engine can take advantage of more than 1 CPU core. Right now it can not, even with many tabs open.
