Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• 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.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

When people with visual impairment set lower screen resolution, higher display scale and larger text view, in order to see better the screen content, uBO main UI isn’t scrollable, if it doesn’t fit entirely on the screen, leaving its bottom part inaccessible.

@gorhill SponsorBlock’s popup UI is indeed scrollable, so a uBO-side solution may be in their code.

The popup panel is scrollable, the issue is that the browser extends the popup panel beyond screen boundary.
