I refreshed FF to improve performance and updated to new version but when I go to get any add-on, the list description says "This add-on is not compatible with your version of Firefox because of the following:" (It gives no actual reason for the incompatibility only describes the characteristics of the add-on listed). Then if I try to download one anyway the download simply fails. Using old windows xp home. The add-ons worked fine before I refreshed and I haven't really noticed much improvement in performance. I'm curious about what happened and what my options are now.

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":

If you see disabled or not compatible extensions in "Firefox menu button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.json file.

You can use this button to go to the current Firefox profile folder:

The files you refer to are in the Old FF Data folder generated when I refreshed, but although I can find an "extensions" folder. Search results show no extensions files any where in the Moz FF directory. Do I need to uninstall FF reinstall the whole thing?

Please excuse me I'm not very good at this. However I did follow your instruction and have located those files. Will try your suggestion to delete them.....This does not seem to have fixed anything. But also now I notice in the extensions section of the Add-ons manager that Avast security, MS.net framework assistant, default mngr, and search helper extension are all disabled.
