New update crashes my entire pc

Can you check the crash logs got submitted and paste a few of them here?

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) 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.)

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

I only have only one crash report beyond 2024 dated to yesterday and when i try to submit it it fails

So ever since the desktop browser got updated i have been experiencing critical crashes and lag where my pc screen freezes and then goes to black until i restart my graphics card and quit firefox in addition to tabs crashing and very weird performance issues overall, any fixes for this issue?

update: the issue seems to be worse when trying to access high fidelity videos or fancy animations

Crashes linked to media, and also not being able to submit crash logs afterwards, have in past been linked to security software, like Eset or Malwarebytes. Would you be able to try turning off anything like that, or at least make sure your antivirus/malware/phishing protection is fully up–to–date, in case they included some bugfixes in recent updates? Thanks!
