Ever since the last 2 updates, whenever I close the browser it almost always disables and uninstalls all of my add-on's requiring me to re-install them and then re-start the browser. This is unbelievably annoying but I don't know how to fix it. This has occasionally happened in the past whenever Mozilla updates but it has only been the last 2 updates that seem to trigger this almost every time I close the browser.

Chosen solution

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

Type about:support in the address bar 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.

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.

See "Corrupt extension files":

You will have to approve the updating one last time.
