opens all pins twice
When I open Firefox all of my pinned sites open as pins and as full size tabs. Every time I open Firefox I have to close all of these tabs so that all that is left are my pinned sites. Is there a setting for this or is it a glitch?

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, so you will have to create them again (make a note or bookmark them).
