Adobe Flash Crashing Mozilla Firefox in Linux

Posted on December 1, 2007

If you are having trouble with Flash crashing Firefox under Linux (Ubuntu in my case), you may want to try deleting (or rename) the $HOME/.macromedia folder. It worked for me.

The crashing in question wasn’t happening most of the time, but it was preventing my from using the Potlatch editor for openstreetmap.org.

A little detail on how I come to find this out:

  1. I renamed my $HOME/.mozilla folder to remove all local firefox preferences. Didn’t work.
  2. I created a new user and tried to use Potlatch. Worked!
  3. Be confused because deleting the $HOME/.mozilla folder should be the same as creating a new user.
  4. Hey, what about Flash – maybe it has some local user preferences. Yep, $HOME/.macromedia. Renamed that. Worked!

It may also be a good idea to ensure that your flash plugin is installed through the ubuntu repositories rather than Adobe’s site to ensure it all works swimmingly with Ubuntu. Just run

sudo apt-get install flashplugin-nonfree

So if you are having similar Flash problems in Linux, give that (and the renaming/deletion of $HOME/.macromedia) a go.
