    Default Firefox won't start (says it's already running)

    Hello,
    when I start Firefox i get the message:
    Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

    but I can't find any firefox related process, nor restart helps.
    I also see no lock file in the firefox directory:

    ~/.mozilla/firefox/af8cu1vg.default> ls
    bookmarkbackups extensions.cache prefs.js
    bookmarks.html extensions.ini search.sqlite
    Cache extensions.rdf secmod.db
    cert8.db formhistory.sqlite sessionstore.js
    chrome key3.db signons3.txt
    compatibility.ini localstore.rdf urlclassifier3.sqlite
    compreg.dat mimeTypes.rdf urlclassifierkey3.txt
    content-prefs.sqlite permissions.sqlite XPC.mfasl
    cookies.sqlite places.sqlite xpti.dat
    downloads.sqlite places.sqlite-journal XUL.mfasl
    extensions pluginreg.dat

    When you put that computer output between CODE tags instead of screaming them out, it is better readable with less space on the screen.

    Try first by renaming the ~/.mozilla directory. Still wrong or not?

    It simply means that that there is something wrong inside your ~/.mozilla directory. You allready assumed that, but only thought about some file having the word "lock" in it (or something like that). So you were trying in the correct direction, but it is apparently not very obvious what it is.

    I can also not exactly tell you which file inside ~/.mozille is wrong. You could look through both directories looking for differences.
    As the renaming you did also removed all personal configurations, history, passwords, etc. you may have stored in FF, this might be needed to do.

    When you do not have much configs, etc., you can decide to remove the renamed directory and just use the new one generated now by FF. That is up to you to decide.
