sidebar spontaneously opens by itself rapidly even when the shortcut is not on the toolbar .
-This is on the most current version of Firefox. - This occurs anywhere in Firefox not on a particular website. - even after refreshing Firefox or reinstalling Firefox the bug is still present. - Clearing cookies,history, or cache does not do anything. - Hiding sidebar shortcut in the 'customize' option doesn't resolve the error

Bummer !
Two more things I would like you to try :
In the profile folder, rename "xulstore.json" to something else, e.g. "xulstore.json.old" and if that doesn't make a difference :
Let's try Firefox in Safe Mode :
If Firefox is not running : Hold down the Shift key when starting Firefox.
If Firefox is running : 3-bar menu => ' ? ' (at the bottom of the dropdown) => 'Restart with Add-ons disabled'. Then OK the restart. A small dialog should appear. Click 'Start in Safe Mode' ( not 'Refresh' !)

It can't be because you restore the previous session, as this doesn't just happen on startup, right ?

Hello oscarrivas480,
Would you please type in the address bar about:support
(press Enter) => Profile Folder => Open Folder
Then check if you have a user.js file in your Firefox profile
folder, and if so : rename it or remove it.
(you'll have to close Firefox first)
Any luck ?
Hi McCoy! Thanks for your help today !
Unfortunately there was no user.js on the Profile Folder.
Is there anything else I can do?

Changing xulstore.json to xulstore.old restored it! Everything looks good now!
Thanks for your assistance McCoy!
