I did a reset of Firefox which was a mistake as it didn't fix my problem.

Anyway i now have a file 'Old firefox data' that includes stuff like Ad Blocker plus so how do i put all of these programs back into Firefox again?

When you reset Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported and the current profile folder will be moved to the desktop to an "Old Firefox Data" folder. Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.

It is possible to recover data from the old profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Thanks Cor-el.

I've solved my problem now and probably don't need most of stuff in my old firefox data folder but if i do i will use your method.
