User reviews

Users appreciate Firefox Color for fixing addon icon display issues and for its helpful customization features. However, many find the interface confusing at first and report problems with theme management, such as overwriting existing themes, faulty revert functionality, and a restrictive 5MB limit on saved themes causing data loss. Additionally, theme import fails due to corrupted files. Despite these drawbacks, users value its capabilities and hope for future improvements.

Pros

Effectively fixes certain icon display problems with other addons.
Provides important and helpful functionality for theme customization.
Highly valued and liked by several users.

Cons

Confusing interface initially, requiring reading instructions to understand.
Difficulties with theme management: themes overwrite chosen themes instead of customizing them.
"Revert all" button removes themes improperly, requiring manual re-enabling of themes.
Limit of 5MB on locally saved themes causes themes to disappear unexpectedly.
Lack of import functionality for themes; issues with corrupted files when importing.

Decent extension with pretty thorough customization but the saved themes tab is covered by the menu preview and I can only access it with uBlock's element zapper. Additionally, the background images are never displayed as they're shown in the preview and the 1mb limit is a bit difficult to work with. A zoom-to-fit or resize option for backgrounds would be appreciated. Would be a 5 stars if not for those QOL issues.
