Cannot request optional permissions in firefox

[eternal-sorrow]

• My browser: Firefox 128.0
• My RES version: v5.24.6
• Am I in reddit beta (yes/no): no

What's the problem?
Whenever I try to expand an image from 3rd party website (flickr in this case), it doesn't work. The "Permission needed" window shows up, but pressing the "Request permissions" button does nothing.

Are there any related posts in https://github.com/honestbleeps/Reddit-Enhancement-Suite/issues or /r/RESissues?

And many others. There is also a workaround for this, but it's hacky.

What other browser extensions are installed?
Many, what are you interested in exactly?
