I have two add-ons, Dlink and Trusteer Rapport not working in Firefox, and can't find fixes

Neither one shows up on the Addons Manager page. Dlink Uplayer-1.0.2.7 was downloaded and installed at least twice. Rapport was reinstalled, and I got a message to complete the protection I must enable the Rapport extension in the Addon Manager but it is also not showing up there, either.

Running version 60.6.3esr(64-bit).

It’s 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.

Windows: Show 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.
