Tab ID is a Firefox add-on that improves tab identification, allowing users to easily distinguish between multiple tabs open in their browser.
Firstly, the colored icon will now show up in more places, including the location bar, 'List all tabs' dropdown, History Sidebar and menu, Bookmarks Sidebar and menu, urlbar autocomplete results, and the back/forward dropdown. This means you can quickly identify the website loaded into a tab, regardless of where you are in the browser interface.
One of the most important features of HashColouredTabs+ is its ability to provide each tab with a unique, colored icon depending on the web domain from which it is loaded. This is particularly useful for websites that don't come with their own icons. With this extension, you can quickly tell which tab is loaded with a website simply by its icon color.
Overall, HashColouredTabs+ is an incredibly useful extension that enhances tab identification in Firefox. With its ability to add a colored icon to each tab, you can quickly identify which website is loaded within each tab, even when using a large number of tabs at once.
