Firefox 153 to Flash Red Icon When Websites Access Your Location
Mozilla will add a red location icon to Firefox’s address bar that activates in real time whenever a website reads a user’s location, according to a post from the official Firefox Nightly account on X.
The change targets the pin icon — the small symbol that sits near the left edge of the address bar — turning it bright red the moment a site begins actively accessing location data.
Currently, the icon appears gray when a site requests location permission via a pop-up. Once a user grants access and the site begins reading that data, the icon turns red. If a user blocks location access entirely, a strikethrough appears over the icon.
The behavior brings location tracking in line with how Firefox already handles camera and microphone access, both of which display visible status indicators during active use.
What Triggered the Change
Mozilla’s internal bug tracker, Bugzilla, shows the change stems from report No. 2038194, which called for making location access more visible inside the browser’s user interface. The ticket has since been resolved and tied to the Firefox 153 release.
The Firefox Nightly account confirmed the update on X and linked directly to the Bugzilla report.
Which Version Gets It
Firefox 153 currently sits in the Nightly channel — Mozilla’s experimental, alpha-stage build that receives one or two updates per day and is intended for developers and testers, not general users.
The adjacent Beta channel carries Firefox 152. The current public stable release is Firefox 151.0.3, which Mozilla pushed on June 2 with two bug fixes.
Firefox 153 is scheduled to move to the stable public release channel in July.
Why It Matters
Location data ranks among the most sensitive categories of personal information a browser handles. By contrast, many users currently have no passive, at-a-glance way to confirm whether a site they already authorized continues to read their location during a session.
The red icon removes that ambiguity without requiring users to open permission menus or settings panels.
For context, Mozilla positions Firefox as a privacy-focused alternative to Google Chrome, which holds roughly 66% of the global desktop browser market, according to StatCounter.
Firefox’s global desktop market share stood at approximately 6.4% as of May 2025, per the same StatCounter data.
