Issolated test case: http://www.naos.co.nz/tmp/ubuntu/firefox/mailman-signon-page.html
Steps to reproduce is slightly different here, I think because there's no real form processing behind it. To reproduce: 1. Go to URL 2 Enter some string to be the password, eg "test" (it doens't matter, just needs something) 3. Choose to remember the password 4. Observe "success" message 5. Go back to URL (eg, click on the link in the success page) 6. Observe browser crashes 7. Restart firefox 8. Go to URL 9. Observe browser crashes 10. Remove ~/.mozilla/firefox/PROFILE/signons.txt 11. Start firefox 12. Go to URL 13. Observe browser doesn't crash 14. Repeat from 2 Test case (stripped down version of the Mailman admin page) is attached. The "success" page is just a stub HTML page with a link to this bug and back to the test case for convenience. Something like the launchpad.net signon form can serve as an example that doesn't crash.
