What should I do when Ubuntu freezes?

I have been having the most annoying problem: every time I open BASH when I am using firefox, it (FF) crashes. Not immediately, but when I start typing - no matter what I type - it crashes... I have recently (today and yday) updated my system using the update manager, and I suspect it has something to do with this, but being a total beginner, I don't know how to review my latest upgrades and uninstall the ones that are responsible. perhaps I need to check for FF updates? I don't think so - I am using the latest (?) version 14.0.1.

Does anyone have any clue how to get to the bottom of this?

This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. – Jorge Castro Aug 5 '12 at 19:23

I'm interpreting this as a question about how to effectively report and investigate such a bug, since actually working on bugs in generally off-topic for Ask Ubuntu (and bug reports are always off topic here).

The best thing to do is to:

  1. Learn how to search for, and how to report, bugs in Ubuntu.

  2. Make sure Apport is enabled.

  3. Reconfigure Apport to submit data to Launchpad for a bug report instead of submitting it for anonymous statistical analysis (since you're running 12.04).

    • You may want to undo this afterwards, if you don't want to file bug reports most of the time something crashes.
  4. Reproduce the crash by running Firefox, starting a Terminal, and using it.

  5. Let Apport submit crash data.

    • If Apport doesn't come up automatically, this might not really be a crash. It mgiht be some other kind of problem. (Sometimes a program quits, and it shouldn't have, but it's not a crash.) If that happens, you can get more information by running firefox from the Terminal.
  6. A browser window will come up where you can submit a bug report. Clearly and thoroughly describe what is going on.
