If the previous version is still available from the current repository: apt-get install iceweasel=exact_version_string_of_previous_version (And you may also need to specify xulrunner and libmozjs* packages, with their exact package versions.) If it is not, you can try adding other repos, such as stable - but AFAIK the exact version you mention is not available in any current repo anymore. You can check /var/cache/apt/archives/ and see if the appropriate *.deb files for those packages at those versions are still available, and install them manually with 'dpkg -i filename.deb'. If the appropriate packages aren't (all) available there, you can download them from snapshot.debian.org and install them the same way. > Any other advice to investigate and restore previous stability and > functionality on this hardware? > > Below are the relevant tail lines of ~/.xsession-errors <snip> > iceweasel: Fatal IO error 11 (Resource temporarily unavailable) on X > server :0. Errors of this form indicate "This application was still running when X exited, so it complained that it didn't have an X session available any more". None of those errors are helpful in figuring out exactly what caused X to exit in the first place. Have you checked /var/log/Xorg.0.log, or similar? That would be more likely to have potentially relevant information. (If X has been restarted, you'll need the backup log from a session which crashed.) In my experience, X crashes are usually either bugs in X or in video drivers. Which can sometimes be triggered by other applications, yes. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
