Tab Highlighter & Info автор Nhà Cái Uy Tín

This extension lets you quickly highlight links on the current page so you can scan navigation paths at a glance. Open the toolbar popup and toggle highlighting; the popup also shows the active tab’s title and URL. You can choose a default color in Options and override it on the fly from the popup. The add-on follows Mozilla’s safety guidelines by avoiding inline scripts and remote code, and it requests only the minimal activeTab and storage permissions it needs.
Under the hood, it programmatically injects a content script only into the tab you interact with, minimizing surface area while keeping performance snappy. No data leaves your browser.
