This issue started recently where if I click websites like Twitter, Yahoo, Imgur or sometimes embedded Youtube videos, I'll get the tab crashed page on Firefox. My add-ons are updated, I tried safe mode, I did the Firefox refresh, I disabled hardware acceleration, compatibility mode is not checked, and also cleared cookies, but none of them worked. The websites work and don't crash when I use a different browser. I'm not sure what info you need, but this is for an older computer with Windows 7, I'm using Firefox 68.4.2esr (says it's the latest version) and the crash reason is EXCEPTION_ACCESS_VIOLATION_WRITE Thanks for any help! Edit: The issue fixed itself when I restarted the computer.
