Since a few days we have a lot of crashes with [http://www.trusteer.com/product/trusteer-rapport Trusteer Rapport]. If you have this program, try to disable it and see if that stops the crashing.<br> You can stop Rapport using Start Menu > Programs > Trusteer Rapport > Stop Rapport<br> You can ask their helpdesk when an updated version of their product will be made available or, if you don't need this software, uninstall it.<br> http://www.trusteer.com/support/en/report-problem<br> ---- If you do not have Rapport, then we need to have a crash report ID. When you send Mozilla a crash report it just puts it in a giant database. We have no way of looking it up without the Report ID. I have no idea what is wrong without looking up the crash report. Please get the Report ID of your latest crash report.<br> See https://support.mozilla.com/en-US/kb/Firefox%20crashes<br>
