Hi, Sorry to chime in here a year later but I had the same problem. After killing all processes and removing lock files the problem persisted. Using the strace method given show below I found the problem.
The problematic file found was: .mozilla/firefox/profiles.ini In my case the .mozilla directory is linked to an AFS-mounted area and Iceweasel started before the files were available by creating an AFS ticket. Then when I obtained access to .mozilla a new profile had already been created in .mozilla/firefox/ and profiles.ini pointed to that directory. Starting iceweasel showed only the new profile, all my links were gone. Moving the new profile away resulted the problem stated in this thread: "Iceweasel is already running, but is not responding. To open a new window, you must first close the existing Iceweasel process, or restart your system." The reason Iceweasel did not start was that the file profiles.ini still pointed to the new directory. Editing the file solved the problem. [Profile0] Name=default IsRelative=1 #Path=xxxxx.default Path=yyyyy.default Maybe somebody else will be helped by knowing this, that's why I'm posting. It might be available in an FAQ somewhere together with the info on killing the processes and removing the lock files. > On Monday 2009 January 05 12:47:08 mitch wrote: (but double-quoted text is > mine) > > "I think maybe stracing that process might be our next step.
