Did you remove each Addon and reinstall them to see what happens.

I have not done it with all of these ones however I have done two of them previously and when I removed them then added them back they were enabled and functioned normally. After about 2 days one of them got disabled in the same way again but the other was still working. Having this many disabled has just happened and is why I finally decided to see if I could get a solution for this because before the most that were disabled was two.

I've only sent a message to one of the developers but have yet to receive a reply. The one addon is made by mozilla/firefox themselves though.

I can't imagine this is something that is a problem with the addons unless there was a change in firefox recently that would do this.

It’s possible that there is a problem with the file(s) that store the extensions registry.

Type about:support in the address box and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show/Open Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

After, restart Firefox.

After removing those files from my profile the addons are no longer disabled. I will give it a few days to see if they get disabled again or if this solved the problem. Will get back to you in a bit thanks for the help everyone.

Thank you both for the help, after doing what FredMCD outlined no plugins have been disabled again. So either it is a coincidence and something else has changed or is not happening anymore or there was some corruption in the files as suggested. Nevertheless it seems to have solved my problem so I've marked it as the answer. Thanks again guys.

This has now happened 3 more times since my previous post, so it seems deleting the files does not help with the issue but rather resets firefox thinking they are bad. If there are any other suggestions I'd love to try them.
