System freeze-up

EDIT: I just thought of another way:
1. Before downloading FF, open thunar, the file manager.
2. Hit Ctrl + h to show the hidden files.
3. Locate the .mozilla folder.
4. Select it and rename it to something like .mozilla.old
5. Launch Firefox from terminal.
What this will do is launch FF anew; no profile, and will create a new .mozilla folder. So, in theory, if something's wrong with your FF's profile, you shouldn't get any errors. In short, this procedure is to check that your FF's profile isn't corrupted or something, and if you don't get any errors, you could delete .mozilla.old. If you do get the same behavior, the download FF and proceed as explained above.

I finally had time to try this (1-5, that is).  I thought it had worked but after a bit the system froze again.  And I am not sure if it is Firefox or not.  When it happens it is usually associated with a mouse click or movement.  All of a sudden it just freezes.

IT'S MADDENING... :banghead

Did you get any errors in the terminal? You might try my other suggestion on downloading FF from its website, extract and run, and I suggest that you rename the .mozilla folder before doing it, to avoid it gets corrupted(it shouldn't happen, but just in case) and by doing so and launching a fresh FF session, might be better to troubleshoot. All of this is to try and narrow down the problem to discover the possible root of the cause.
