Firefox: colour your browser
Apply dynamic themes per window, following the active tab. Adjust frames, tabs, toolbars and address bars with automatic or custom palettes. The preview is approximate; changes apply when saved.
LABRACODE / Domain Colors
Colours for your domains. Context for your work.
Domain Colors is the LABRACODE extension that helps distinguish sites and environments with colours, rules and labels. Bring context to browsing and to work across development, staging and production.
Recognise every environment at a glance
Chromium: clear signals on every site
Chrome and Edge use toolbar badges: ON, custom text, environment or hidden. The optional top bar requires permission per site and supports 2–8 px, including rule overrides. It does not change the full browser theme.
Your rules, your way
Assign colours to domains and subdomains. Personal mode simplifies editing; Developer adds ports, paths, priorities and exceptions. Switching modes preserves advanced rules.
Profiles and environments
Group rules into project profiles and pause them as needed. Use labels to distinguish local, development, staging and production. Labels are visual aids, not security guarantees.
Firefox Sync, only if you choose
Synchronization is off by default. Share settings through Firefox Sync after enabling and consenting on each device. Conflicts require reviewing complete versions; rules are not automatically merged. Chromium does not use Sync.

User guide and troubleshooting →Frequently asked questions
Does it work on every page?
The Chromium bar requires an authorized HTTP/HTTPS site. It cannot run on internal or restricted pages. With no matching rule it stays hidden unless you enable the fallback colour.
Can I move rules to another browser?
Yes, by exporting and importing JSON. Firefox palettes are preserved in Chromium even though their specific controls are hidden. Import replaces settings; it does not merge rules.
Does pausing stop synchronization?
No. Pause removes the visual effect and keeps settings. Turn Sync off using its own switch.
