Tab Renamer X by Xero

Tired of cryptic tab titles, long site names, or tabs that all look the same? Tab Renamer lets you take control.
Quick rename — Click the extension, type a new title, and apply it to the current tab instantly.
Persistent rules — Create rules that automatically rename tabs every time you visit a matching URL or page title. Renames survive page reloads and SPA navigation.
Flexible matching:

Wildcard — Simple and intuitive. Use * to match anything. Examples: github.com//issues, .pdf, https://mail.google.com/*
Regex — Full JavaScript regex support for power users, including capture groups in the replacement title

Match against URL or page title — Rules can target the full URL or the page's own title, whichever makes more sense for your use case.
Case sensitivity toggle — On by default for regex, optional for wildcards.
Enable/disable rules individually — No need to delete a rule to turn it off temporarily.
No data is collected. No network requests. Everything stays in your browser.
