Firefox tab hangs when opening maps.google.com and certain other sites

Lately (possibly since updating MacOS to Mojave, not sure), certain websites such as maps.google.com reliably cause a tab to hang indefinitely (with the grey rotating circle). This then causes other tabs to hang or not load properly until I restart Firefox, and I'm unable to quit Firefox normally, I have to force quit. I have no issues in Safe Mode, but I've tried refreshing Firefox, removing all add-ons and themes, disabling hardware acceleration, and the problem still occurs when not in safe mode. I'd really appreciate any help I can get with this, it's not only frustrating but is impairing my ability to do my job.

Chosen solution

I seem to have figured out the solution. After a lot of searching, it turns out the MacOS Mojave deprecated WebGL. I had to follow these instructions to disable it in Firefox, which fixed my issues: https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration#w_disabling-webgl
