• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

• uBO is the only extension.
• using a new, unmodified browser profile.

Where are you installing uBO from, and what specific browser version are you using?

Theoretically I see two problems, plugins are not extensions/addons and Firefox 85+ blocked NPAPI (plug-in) imports.
