Firefox crashing

A few weeks ago Firefox 82.0.2 (64bit) became hellishly sluggish, and then a few days ago, began crashing. I did everything suggested on the Mozilla Troubleshoot list (e.g., Update, Start in Safe Mode, Virus & Malware check, hardware check, Refresh Firefox, etc) but it is still occurring--to the point I'm now compelled to use an alternative browser. However, I'd PREFER to use Firefox.

My only option as I see it is to Uninstall and Reinstall. Am I missing an easier/cleaner fix? Is a Reinstallation likely to fix the issue, or is there something else happening?

Cheers A

We do not recommend using other programs to clean Firefox because they could corrupt the files. Also, the browser can clean itself.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most recent 7 - 10 Submitted crash reports, and copy them. Now go to the reply box and paste them in.
