Settings menu refuses to open in Firefox

[Hyde233]

For some reason, the settings menu refuses to open. It stays stuck on a blank white screen:

I've tried uninstalling and reinstalling the extension, and I've restarted my computer a couple of times, but it still doesn't work. I also tried disabling every other extension to see if it'll do anything; it still won't work.

I decided to try installing the extension on an alternate profile, and it worked on that one. The menu just refuses to open on the main profile I want to use it on for some reason.

Stange, I haven't heard of this issue occurring before. What browser version are you using?

Stange, I haven't heard of this issue occurring before. What browser version are you using?

I'm currently using version 72.0.2 (64 bit).

On a side note, I also tried opening the plugin menu on another computer and I'm having the same issue. Both computers are connected with the same Firefox profile, so I think the issue might have something to do with my Firefox profile and/or browser settings.

I was unable to reproduce the error using Firefox version 72.0.2 (64 bit) and Thumbnail Rating Bar for YouTube™ version 0.1.2.

Perhaps you can check if the extension is producing any informative error messages:

1. Navigate to "about:debugging#/runtime/this-firefox" .
2. Click the "Inspect" button next to the "Thumbnail Rating Bar for YouTube™" extension, which will open a new tab with a view of a console.
3. Then click the extension button in the toolbar to try to open the settings window.
4. Check if any error messages were printed to the console.

Three messages appeared:

The first two messages already appeared before I tried opening the settings menu. The third one appeared after.

Ok, I get that third message too, so I don't think it is the cause of the issue.

I'm not sure what else to try. If you somehow figure out a solution in the future through changing the account settings or something, I'd be interested to here what fixed it.

[Hyde233]

I figured out what the issue is. It wouldn't open because it was pinned to the overflow menu. After I unpinned it, it started working again.

Got it. Good to know. Thanks for posting the fix.
