I imported my post from another thread. FF12 beta 1 was released around March 16, 2012, followed by five more betas. The most recent beta 6 around April 18, 2012. A supposed final was released around April 22, 2012. I have read that there is some user confusion as to it being an actual final version, or just a RC (release candidate). I have also read some reported concerns regarding stability of this final/RC version. I myself am waiting for a clarification and a popular position on the release. As always, with any application a user must use caution when exploring betas and RCs. DA

Export them to a file on a thumb drive then import 'from file' on the new computer. A floppy would work if both computers have floppy drives.

I could not go back to NOT using tabs can not even imagine it. Once you start and get used to how much time it saves you and how easy it is to do you will quickly start to love them. Plus it is easier on your pc to have only mulitple tabs open rather than having multiple instances of complete windows open. This is one thing I love about tabs. I can set up a folder up on the bookmarks toolbar in that folder I put the links to every site I visit every day, like this forum, the other forums I am on, my netvibes page which contains all my rss news feeds, my email sites. Then in the morning I go to that folder easily accessible on the top of the firefox bar right click on it and select open all in tabs. Bam immediately I have my full list of tabs open in one movement now that is a huge time saver, They are there open and ready for me to visit one after the other. I have another folder up there called tools in that one I have the links to all the security programs I have to recommend or list many times a day when helping people with pc issues, I do not have to go looking in favorites or google or where ever for them I have them all right there in that folder on my bookmarks toolbar, I left click the folder go to the one I need right click it to open in new tab and I am there. Huge asset.

Yeah, sorry, I'm not expert enough to explain the difference, just pointing out that there is a difference. My banking sites work fine without Java. I wasn't implying your problem is Javascript, just that it's not Java. Javascript is not something you manually update, it's built into the browser and updates when you update the browser. Personally, I wouldn't rush to reinstall Windows if all the problems are in Firefox. First, I'd try the "reset" that you tried. If that didn't work, I'd uninstall Firefox and reinstall it. If that didn't work, I'd do it again but make sure it didn't leave anything behind. Make sure it removed my old Firefox profile, maybe even run CCleaner's registry cleaner to make sure all Firefox registry entries were removed. Then if after all that it still didn't work right... I'd consider reinstalling Windows. I'm not an expert though so I'm saying that's what you should do, just telling you what I'd do. BTW, every time I've ever reinstalled Windows, I dreaded it but ended up glad I did. Machine ran snappy new again. Sorry I can't help more.
