We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

I cant enter anything into the address bar as as soon as I start firefox crashes, same as main menu bar. It is sending the crash data each time automatically to you.

What other A/V program is being used? And when you uninstalled all FF did you also delete the Mozilla folder before reinstalling?

Im running MAcaffe A?V. I did delete the folder but will try again and reinstall

Nope makes no difference main menu and address bar any use crashes firefox
