Tab Modifier
The Tab Modifier project describes a Chrome extension for changing tab behavior, though its supplied page offers only the broad phrase “Take control of your tabs.”
About Tab Modifier
Tab Modifier, referred to as Tabee in its README, is an open-source Chrome extension that changes tab behavior through user-defined URL rules. It can rename tabs, change icons, pin, group, prevent closing, enforce unique tabs and mute tabs. Rules act when a tab is opened or refreshed, using the first matching rule. The README lists install links for Chrome, Arc and Brave, says Opera and Microsoft Edge installs are available soon, and states that Firefox and Safari are not available.
The extension is built around rule-based URL matching, including contains, starts-with and regex matching, with title placeholders. Known limitations include no operation on chrome:// pages, no local file access unless the user opts in, and local icon paths not working. Pricing is not stated.
Key features
- Applies rule-based tab actions matched by URL on tab open or refresh.
- Renames tabs and adds prefixes or suffixes using title placeholders.
- Changes tab icons with preset icons or custom icon links/Data URI.
- Pins, groups, mutes, prevents closing, or enforces unique matched tabs.
- Supports contains, starts-with and regex URL matching, plus URL matchers.
- Quickly renames a tab by right-clicking anywhere on the page.
Best for: Web developers and others who manage multiple similarly named tabs and need to distinguish environments or enforce tab behavior by URL.

Tab Modifier FAQ
How does Tab Modifier decide which rule to apply?
It acts on the tab URL that matches the first seen rule. The extension checks the URL when a tab is opened or refreshed and applies the rule's actions.
Can I rename a tab without creating a rule?
Yes. Quick rename can be done by right-clicking anywhere on the page and selecting 'Rename Tab'.
Why do some pages or local files not work?
Pages starting with chrome:// are protected and no content script can be injected. Extensions also lack local file access by default; users must opt in to allow access to file URLs.
