Every time I open firefox I get a second tab (another program on your computer would like to modify firefox with the following add-on). It doesn't allow me to say no just yes or continue. If I hit continue then the next time I open firefox it is there again. How can I get this to go away?

This usually happens if other software install an extension globally (e.g. via the registry).

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.
