My Firefox just did an automatic update (I did not choose to update) to a new version that won't run on my computer because it isn't compatible with my Mac OS (10.5.8). I am considering upgrading to a newer OS, but in the meantime, I'd at least like to be able to get my old bookmarks, but can't because Firefox crashes every time I attempt to open it. Why would you force me to upgrade to a version that you already know won't work? This is incredibly frustrating!
