Firefox 16.0.2 do not complete the installation under windows 7 and keep doing add-ons compatibility tests and asking me if I want to send feedback to Mozilla
It works as if it was doing the first run after updating. The point is that it never ends. After every launch it goes tru the whole cycle as if it were being installef for the first time.

I have used the tool "reset the firefox" under "Help" and, after two launch cycles, it stopped the weird behavior. Thank you very much for your answer Cor-el. I believed that, under an undirected way, the mentioned tool performed some of the procedures you proposed.

You can check for problems with preferences and try to rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default values.
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.
