TST Colorize Tabs is a Firefox extension designed to enhance the personalization of your browsing experience by allowing users to assign individual colors to each tab. This feature helps in distinguishing between different tabs quickly, making it easier to navigate through multiple open pages. The extension requires the Tree Style Tab extension to function properly and may conflict with other similar extensions that alter tab colors. Users should also note that tab colors will not persist after closing and reopening tabs.

The extension provides keyboard shortcuts for quick color assignment, enabling users to set colors such as red, green, blue, yellow, brown, purple, and orange to selected tabs. Additionally, users can remove colors or switch between colorized tabs using designated key combinations. Customization is further supported through Tree Style Tab's CSS settings, allowing for detailed adjustments to color styles. Overall, TST Colorize Tabs offers a straightforward way to enhance tab organization in Firefox.
