## Description

Favicon Customizer is a handy Chrome extension designed to let you personalize the favicon for any given URL. It's especially useful when you manage multiple versions of the same website—for example, different Gmail or Google Calendar accounts for work and personal use.

By assigning unique favicons, you can quickly identify each tab at a glance without confusion. Note that after changing a favicon, the update takes effect once you reload the relevant browser tab. This tool enhances your browsing experience by making site differentiation effortless and visually clear.

## Review summary

Overall, users find favicon-customizer useful for making tabs easier to identify by replacing the tab icons. It seems especially valued for pinned tabs and for sites with many open tabs; some users also note it works for general tab icons on any site. However, the extension struggles with bookmarks: changes aren't reliably saved for bookmarks and can revert, and bookmark icons may not reflect the custom favicon. There are cross-platform and version issues (MacOS, Firefox updates) and reliability concerns about the icon applying only when the tab is active. Documentation is also lacking.

### Pros

- Changes the tab favicon to make tabs more recognizable.
- Helpful for pinned tabs and for quickly identifying tabs, especially for large sites.
- Applies to any website's favicon on the tab (not limited to a single site).

### Cons

- Bookmarks icons are not reliably updated or saved; bookmarks can revert to the original.
- Cross-platform/Firefox-version issues; reports of not working on MacOS or after updates.
- Icons often apply only when the tab is active and can disappear on background tabs or tab switching.
- Poor or missing documentation makes it hard to use.
