Firefox grabs 50% of CPU and sits there, won't open.
I have regular firefox installed on my desktop. I copied my firefox portable installation to c:\portable\firefox and for a while I was using that firefox, even though when another program asked for my default browser, it would activate the "regular" one in program files. Then the portable one started simply not opening. I could see in the task manager that both firefoxportable.exe and firefox.exe were running. And firegox.exe was grabbing 49/50% of the CPU and stuck there. Kill it, try again, same thing. Usually around the 4th or 5th time, it would come and be just fine.
Decided to stop using the portable version and copied the profile from portable over to the applications folder that had the default profile for the desktop version in program files. Worked great. But after two days or so, the problem described above is back and lo and behold, there is no longer an installation of firefox in program files!
How do I get out of this mess? I really want to keep my bookmarks and plugins and etc. etc.
After some time I get an error dialog box will tells me about the plugins are not up to date. How do I solve this Chicken and Egg situation?
