diogenysos: Last time something like this happened to me, turned out to be an Upgrade problem to do with Microsoft's automatic updates.

But you could try un-installing Firefox and installing a previous version.

(V):Hehe, first time i experienced that bug, i uninstalled that firefox 3.5 and installed version 2.xx and all worked fine.
This time even that trick does not work v;-)

diogenysos: Sounds like an update glitch from Microsoft then. I'm only saying that as one of their updates caused conflicts with our internet security software. I'd go through any recent updates from them and uninstall the latest... or give them a call and get advice!!

The other option is... http://www.combofix.org/ .......... It's a desktop run program that scans deep and gives a full report on the likes of registry issues. But make sure ( as prompted) you use the back up option first.

But I'd lean towards it being an update conflict.

(V):That sounds interesting and ill go and prove it - as i experienced the bug on an xp- _and_ a vista-computer...
browsing through all the firefox-chatrooms i meet some people who have the same probs... but one user even under linux...
this would mean the bug has nothing to do with the MS updates - but well, ill give it a try anyway!

diogenysos: Weird.. I'm using firefox 3.5.3 and having no problems (Win XP) ... I heard there were some 'glitches' but things are fine.

(V):IT WAS WINDOWS!!!
Maybe they're doing it on purpose?!

I uninstalled the latest "windows-security-update" (from the 9th of September)
and now firefox 3.x is working fine...

Just another poor attempt to "push" the IE?

diogenysos: Maybe. Probaly sour grapes... they have been finding themselves on the wrong end of the law recently alot.

Maybe Bill is not happy he's making so much money now.. as if he needs more!!
