I needed a quick UI element in Chrome to know the environment of the tab, as a Web developer I often use multiple versions of the same website: local, pre-production and production.

Not easy to find the appropriate tab when you have multiple tabs called "My awesome website".

I created Tab Modifier to add prefixes to website titles with a specific match.

  • [DEV] My awesome website: .local.domain.com
  • [PREPROD] My awesome website: .preprod.domain.com
  • [PROD] My awesome website: .domain.com

After that, I have added more features like "auto-pin", custom favicons and more.

Focused scope

Tab Modifier is based on user rules and act on the tab URL that matches the first seen rule.

Aware of that, there is no reason to include a feature that is not "rule-based". Prefer to install specific extensions.


Install from the Chrome Web Store.

Also available for Opera Browser.

Not available for Firefox, refer to #46.


  • Click on the icon icon to open Options.
  • Create your tab rules.
  • Try & enjoy!

Known issues

Local icon path doesn't work

Related issue: #5

Due to browser security restrictions, this path won't work: file://<path>/icon.png. Your icon will not be shown by Chrome.

Alternatively, you can upload your icon somewhere like imgur.com and paste the direct link in your rule.

Another solution consists in transform your image in the Data URI format. Go to duri.me and drag & drop your icon, then click on "Copy as DataURI" and paste it (the long text) in the icon input on your rule.

Chrome system pages chrome://

Related issues: #11, #14

Pages that start with chrome:// URL are protected. No content script can be injected then Tab Modifier will not work on these pages.

Local files file:///

Related issue: #13

By default, extensions don't have access to local files. You have to opt-in "Allow access to file URLs" from chrome://extensions/?id=hcbgadmbdkiilgpifjgcakjehmafcjai.
