Pinned tabs no longer there & cant add new ones
When I open Firefox, the areas where the nine pinned tabs used to be are blanked out.
I can no longer click a site that was in them and I cant add new ones.
I have done an uninstall and reinstall of Firefox, this didn't work.

Can you please try Firefox in safe mode? (More Details)
When you performed your reinstall, did you ensure to remove all Firefox files including the application data and your profile folder?
If not please perform another reinstall following these steps.
Also, please remember to scan your computer for malware or other infections. These could cause functionality issues with Firefox.
I recommend using Hitman Pro.
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
