To help you further with this problem, it will probably be best if you can provide us with some crash reports. This will provide some more information about the crash that you are experiencing.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted 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.)

In the meantime, some general troubleshooting tips can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Hope this helps.
