Add-ons don't appear in Firefox 57
I upgraded Firefox on my laptop to the 57 beta about a month and a half ago, and that went quite smoothly. But on my desktop PC, none of my add-ons/extensions appear in my toolbar, or in the "customize" menu to move to my toolbar. I've tried disabling/reenabling, uninstalling/reinstalling, and nothing has worked yet.
EDIT: Please note that these are COMPATIBLE and ENABLED add-ons. I am well aware of the new WebExtensions requirement and that most of my old add-ons will not work. These incompatible add-ons are currently DISABLED and are not related to my problem.

I tried doing a "refresh" and that fixed it. Thanks for your help, FredMcD.Read this answer in context 👍 0

It's possible some of the add-ons are not compatible with the new Firefox.
Type about:support in the address bar and press Enter. Under the main banner, press the button; Copy Text To Clipboard.. Now in the Reply Box on the forum page, do a right-click in the box and select Paste.

Yeah, a lot of my add-ons are incompatible after the WebExtensions apocalypse. :( But they are disabled and in the "incompatible" list. I'm talking about the ones that are active and (supposedly) working.
Here is my data:
EDIT: I can't post it because the post exceeds 10k characters, and I can only attach images, so I guess I'll put it on my FTP and link it: http://www.nonegrade.com/shared/firefox-about-support.txt
That was good work on your part. I called for more help.
Thanks for your help!
I still haven't been able to get any of my add-ons to work.
Don't want to seem arrogant but you should all have known that with FF57 all Legacy Add-Ons would cease to work! I installed as many compatible replacement extensions while still using FF56. So far my FF57 experience has gone fairly smooth!
You need to re-read the thread.
Do any developers monitor this forum?

None of this has anything to do with my problem. Incompatible add-ons are a different issue. I have a number of incompatible add-ons installed, and they are currently disabled.
The issue I'm having is that COMPATIBLE AND ENABLED add-ons in my browser do not show up on my toolbar, and do not appear in my "customize" menu to drag to said toolbar.
Here are screenshots showing my issue.
It’s possible that there is a problem with the file(s) that store the extensions registry.
Type about:support in the address bar and press enter.
Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Delete all extensions files and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
After, restart Firefox.
See "Corrupt extension files":

Unfortunately it didn't work. Thanks for the suggestion, though.
Well, this is at least somewhat useful, because I'd like to downgrade on my HTPC to use a couple of important add-ons I use on it.
But again, DISABLED ADD-ONS ISN'T MY PROBLEM HERE.
