Firefox 63 - tabs crash VERY frequently on websites requiring computation (e.g., Google Doc/Drive) in Ubuntu 18.04

Hey everyone,

My tabs keep consistently crashing on specific websites, it's hard for me to describe since I'm not an expert, but it's pages where there's some sort of heavier processing going on - like running Google Docs or sometimes just doing like a Captcha or uploading documents. Gmail also crashes VERY frequently. I've been putting up with it for a while since tabs usually reload quickly, but I'd love to get this figured out since I'm increasingly relying on Google Drive for work.

Important to note that I'm using Ubuntu 18.04 which is otherwise completely stable. Firefox is also the most stable web browser available for me. I have tried several solutions that have worked for other people:

-I tried setting browser.tabs.remote.autostart to FALSE and that actually led to the entire firefox program crashing instead of tabs! Weird. And worse, so I set it back to TRUE.

-I updated my graphics drivers, I have an Intel® HD Graphics 520 (Skylake GT2) graphics card, I updated using this link, which seemed to help only momentarily.

-I have disabled hardware acceleration. This actually made no difference at all.

-I have disabled WebGL but it didn't make much of a difference. webgl.disabled is currently set to FALSE since it didn't help.

My computer has had some larger mysterious problems that forced me to switch to Ubuntu from Windows, I suspect it has something to do with my GPU but I don't really know.

Anyway if someone has suggestions on how I can be more specific with describing the problem, please let me know. Thank you for your time!

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 Firefox crashes - Troubleshoot, prevent and get help fixing crashes article.

Did you try Firefox Safe Mode?

The crashes might be JavaScript related and Safe Mode disables the JavaScript JIT compiler.

Thanks for the suggestion, I forgot to mention I'd tried that.

If it's helpful, here's a fresh crash report from safe mode:

Hello, has anyone been able to look at the crash reports? This is still an ongoing and frustrating problem.

Okay I will just consider this unresolvable.
