User reviews
Pros
- Allows customizing tab icons for better recognition of pinned tabs.
- Easy to use for changing website favicons beside tab titles.
- Helps keep bookmark toolbar cleaner by assigning icons to sites lacking favicons.
- Supports setting custom favicons that improve visibility for users with many tabs.
- Generally works well on Windows systems.
Cons
- Does not change favicons in bookmarks reliably; bookmark icons often revert to original favicons.
- Requires being on the active tab for the icon change to apply; icons can revert if tabs refresh in background.
- Lack of clear instructions or documentation makes it difficult for average users to utilize effectively.
- Does not work on some platforms like Mac OS Monterey and may have compatibility issues with certain Firefox versions.
- No support for wildcard or multiple URLs per icon leads to repetitive configuration.

Works perfectly for my use case: needing a few of my pinned tabs to be more recognizable.
Note that the logo needs to stay square in shape, otherwise it will be stretched.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
favicon-customizer requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
favicon-customizer has earned a fairly good reputation and likely can be trusted.
