Pinning add-ons to Toolbar is broken.
Some recent update has changed the way extensions function in Firefox. I used to be able to pin my extensions on the toolbar between the account icon and the extension icon on the toolbar. This is REQUIRED for certain extensions to function properly. One example is uBlock; when visiting a site it actively updates the icon letting you know its working and blocking unwanted items. Same with Facebook Container. Password managers such as 1Password also have stopped working for me unless they are pinned to the toolbar. You use to be able to click the extension icon and then see the list of extensions in a window. Now when you click the extension icon it opens to the Recommendations tab of Add-on Manager. You then navigate to extensions and see you enabled extensions but there is no option to pin, only manage/remove/report. I was able to fix this behavior once by completely uninstalling Firefox and then removing the left over folders on the C: drive. Once I reinstalled and went through the initial process of adding the extension, it also asked me if I wanted to pin to the toolbar. To which I said yes and got things working again. After clearing my browser history and cookies, then turning that feature off, it also blew away my pinned extensions. Even after removing the extension and re-adding, I do not get the prompt to pin like I mentioned above. So its seems I may have to go back and uninstall/delete folders/reinstall to get this working again. I see several similar posts so this appears to be either a bug or a very poor design choice on the part of Mozilla.
How do I fix this? I'm not able to use any of my extensions now and really don't want to have to randomly uninstall/reinstall every time this issue happens.

Just an FYI for others. I remove the folders in this location:
C:\Users\<YourUsername>\AppData\Local\Mozilla\Firefox
C:\Users\<YourUsername>\AppData\Roaming\Mozilla\Firefox
I also removed the Mozilla Registry key under Software which is located in both local computer and local user. That part is probably overkill.
I've rolled back to version 137 because I recall having the issue begin around April/May, but thats not to say 138 and above has this issue, I just didn't try those first. I do know 143 & 142 have the issue, at least. I got the older version from here: https://ftp.mozilla.org/pub/firefox/releases/ Don't forget to turn off automate updates.

The Extensions button should still drop down a list of active extensions. (Manage your extensions using the extensions button in the toolbar)
If it takes you to the Add-ons page, please check:
(1) The extensions you want to use are enabled on the Extensions panel: the slider switches should be blue and to the right.
(2) The extensions you want to use in private windows are allowed to run in private windows (purple mask icon next to their names). See: Extensions in Private Browsing.
(3) Firefox did not start up in Troubleshoot Mode, which disables all extensions until you exit/quit and restart Firefox normally. If you did not intentionally start Firefox in Troubleshoot Mode, please see this article: Firefox is stuck in Troubleshoot Mode.
Any improvement?

If you have a situation in the future where you think your accumulated browser data might be causing the problem, instead of deleting all of your data, you could try this:
New Profile Test
Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.
Take a quick glance at the page and make a mental note of which Profile has this notation: This is the profile in use and it cannot be deleted. That is your current default profile.
Click the "Create a New Profile" button, then click Next. Assign a name like Test2025, ignore the option to relocate the profile folder, and click the Finish button.
Firefox will switch your default profile to the new one, so click the Set as Default Profile button for your regular one to avoid an unwanted surprise at your next startup.
Scroll down to Test2025 and click its Launch profile in new browser button.
Firefox should open a new window that looks like a brand new, uncustomized installation. (Your existing Firefox window(s) should not be affected.) Please ignore any tabs enticing you to connect to a Sync account so you can test your preferred extensions without the old settings. Go ahead and install one that hasn't been working well.
Can you pin extensions to the task bar in the new profile?
When you are done with the experiment, you can close the extra window without affecting your regular Firefox profile. (Test2025 will remain available for future testing.)
