Look I was receiving a 400 Bad Request error from firefox on certain pages, looking for technical information I read that problem was probably that some files may get corrupted and the best thing to do is to create a new profile and import my old profile info into my new one, all of this using the ProfileManager app. from Firefox. I read some pages on the subject and created a new profile called, then I wanted to use a different name for the profile and different folder so I decided to delete this newly created profile. Notice I didn't transfer any files or info from the old one to the new one yet. So I used the delete profile feature on ProfileManager and when asked I choose to delete files, I repeat I only selected the newly created profile for selection didn't touch my 'default' profile where all my info was supposed to be still. Then I tried to open firefox using my default (old) profile I get a message saying: Firefox cannot open default profile because it's in use. To continue either close the firefox instance or choose a different profile. Looking at the profiles folder it seems the ProfileManager also deleted the folder and archives on my default profile folder and I never choose this option I only tried to delete the newly created profile. However ProfileManager is still listing the default profile because the profile.ini file still has the following entrance: 7ckk3nl1.default Which is the one of my default (old) profile. I think I'm screwed however wonder if there is a way in which I can recover my old (default) profile which I never intended to delete. I'm working on a Windows XP platform.
