How can I fix firefox tabs crashing?

Ever since the end of February Firefox has had a habit of crashing on me at random, usually just a tab or so but there's been times where the whole browser just ups and crashes. I am using Firefox 73.0.1 (64-bit) on a Windows 7 Professional computer.

1. This mainly occurs when viewing a video (mostly Youtube), scrolling down on pages, or opening or switching to a new tab.

2. Beforehand if there were issues it would take a few seconds to load the tab, now it just instantly crashes.

3. I've tried uninstalling and re-installing, clearing everything, turning off add-ons, and changing options and nothing has worked. At best, I've stopped it from crashing on launch and disabling add-ons.

4. This issue does not happen on other browsers, nor has my computer shown any unusual behavior.

5. It did not start immediately with the new update, which I got the 20th. It started occurring a week or so after.

Chosen solution

My RAM seems to be fine,

The issue appears to have been resolved however. It seems there was a bug involving offline data and cache that kept crashing Firefox and deleting it. When it got a chance to actually store the data the crashes stopped and Firefox is running. Or the newest version of Firefox fixed the problem. Thanks for the assist though!
