• 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

Ticks in uBO settings checkboxes are very faint when enabling Windows 11 high contrast dark themes, which are used by visually impaired people. The issue can also be reproduced in Windows 7 when selecting dark theme in uBO settings.

Steps to Reproduce

1. Enable a high contrast dark theme in Windows 11 (e.g. “Night sky”)
2. Open Firefox and set its theme either to system default or dark.
3. Open uBO settings.

Expected behavior

Ticks in uBO settings checkboxes are legible when using Windows 11 high contrast dark themes, thus assisting visually impaired people to see them easily. This happens only if we change uBO theme to light, but doing so makes main uBO icons very faint.

Actual behavior

Ticks in uBO settings checkboxes are very faint when using Windows 11 high contrast dark themes.
