I use Roboform also. This is why I never upgrade a new version of Firefox for several weeks after it is announced...it takes time for all the plug ins and add ons to be updated also. No new feature is worth mucking up Roboform.

However, you can use Roboform with IE until you get Firefox straightened out.

Seems to me that you might be able to uninstall Firefox 5 and get a copy of v.4 to replace it, then get the Roboform plug in for F4.

Also, contact Roboform Tech Support (they are fantastic and reply to Email within hours), and ask when they will have a plug in for vF5. It's possible they already have it on their website.

When installing V5 I did not get the opportunity to halt the installation. As soon as I said "Check for solutions" for my add ons V5 loaded with no chance of backing out. And I notice that in all of these support questions, Mozilla NEVER really tells anyone how to uninstall the new version and reinstall the previous version (without losing all your setups, bookmarks, etc.).

I would be very surprised if Roboform didn't have a update available on 06-21 when Firefox 5.0 was released! They are the only "security" program that I heard of that supported the Firefox 4 betas right up thru the release of Firefox 4, so it would shock me if they didn't keep up with Mozilla's progress with Firefox 5.0.
