When I start Firefox, for the first time after starting Win 10, it opens with a tab for the installation of each of my addons, eg: Roboform etc. I go through the process of adding them, or just close the tabs and everything works OK. If I do a PC shutdown or restart it happens again. I am running Win 10 Pro 64bit. I have tried refreshing Firefox and also done a complete uninstall / restart / install. I have scanned my PC for Malware /virus and it is clean. Please help. Regards, Ken

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

If the above did not help,

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

Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

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 it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Locate the files. Then rename or delete it. Restart Firefox.

Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.
