What is tab-labeler?

Tab Labeler is a browser extension for Chromium-based browsers, such as Chrome, Edge, and Brave, that lets you rename any open tab with your own custom label. When you have many tabs open, browser tab titles are often long, auto-generated, or hard to tell apart at a glance. This extension gives you a small popup where you type a new name for the current tab, which shows up in your tab bar in place of the original title. Labels stay in place as long as the tab is open, even if you reload the page. For pages that update their own title automatically (single-page apps are a common example), the extension reapplies your label so it does not get overwritten. The popup also shows a list of all tabs you have labeled in the current session. You can reset any tab back to its original title or clear all labels at once. The extension includes a set of quick-apply presets with emoji icons: Done, Important, Read Later, Bug, and Testing. You can also type any custom name or emoji prefix yourself. A keyboard shortcut can open the popup without clicking the icon. All labels are saved only in your browser's own local extension storage, on your device. There is no server, no account, no sync between devices, and no analytics of any kind. The only browser permissions the extension requests are storage access for saving labels, tab access for reading and listing tab titles, and content script access to update the title displayed on web pages. Installation requires loading the extension from source. The README includes step-by-step instructions for building it and loading it into your browser's developer mode.
