The "Mozilla Start Page" tab appears as expected, but it is followed by several (6 - 9) tabs that are requesting installation of only 2 or 3 plug-ins/add-ons. I click on the ones i want to allow installation of, then restart Firefox. When Firefox comes back up, there's those infernal tabs again. Allowing installation 1-at-a-time has no better effect.

I'm tired of closing tabs and restarting Firefox.

What do I do to make the tabs stop appearing? I've allowed installation for the add-ons/plug-ins I wish to keep.

Thank you for your time and help

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

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

New files will be created when required.

See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

If this hasn't helped then also try to delete the addons.sqlite file.


Which security software (firewall, anti-virus) do you have?

If it still happens then your security software may be protecting files in the Firefox profile folder.
