Website buttons that launch javascripts are ignored. After this, FF may hang or crash, or continue. Javascript is enabled in Options. I have deleted prefs.js and reinstalled FF to no avail. All works OK in IE7.

This happened

Every time Firefox opened

== apparently a random occurrence, can't specify any specific time.

Chosen solution

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window to disable all extensions. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Also check the settings in ZoneAlarm and ForceField to make sure that they aren't causing your problems.
