Try with New Firefox Profile

Create a new profile as a test to check if your current profile is causing the problems.
See Creating a profile:

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

(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!

If necessary then you can open about: pages via the location/address bar.

Note that there will be a Firefox 37.0.2 release in a few days that will address some issues with D3D11 WARP.

Tried the above suggestion - the problem still occurs. Will wait until the next release is out and try again.

There is a 37.0.2 release scheduled that should be released within the next day(s). The Release Notes are already online:

Release 37.0.2 solved the problem

I have the same problem. I use version 40.0.3. I had google maps crash problem a few months back but there was no problem for the last couple of weeks. It started to crash again immediately after I access Google Maps.
