ChaseKnowlden, do you have steps to reproduce or website address where this happens?

Using a lot of memory is not a security issue. There are lots of ways to make the browser use a lot of memory.

Maybe we are experiencing the same issue. I already hijacked https://bugzilla.mozilla.org/show_bug.cgi?id=1854628#c11 which looked like my issue. That you wrote "Pages infinitely load" got my attention. Because this is also what I see when hit the problem and GPU memory usage will sky rocket.

Could you please add GPU information and which driver version you are using?

This bug was moved into the Performance component.

:knowlden887, could you make sure the following information is on this bug?

  • For slowness or high CPU usage, capture a profile with http://profiler.firefox.com/, upload it and share the link here.
  • For memory usage issues, capture a memory dump from about:memory and attach it to this bug.
  • Troubleshooting information: Go to about:support, click "Copy raw data to clipboard", paste it into a file, save it, and attach the file here.

If the requested information is already in the bug, please confirm it is recent.

Thank you.
