Chrome starts updating every two weeks today. Firefox got there first.

Chrome 153 is the first release on a new clock. From today, a new stable version arrives every two weeks rather than every four, on desktop, Android and iOS alike. Google flagged the change back in March; Chrome release team manager Ben Mason and distinguished engineer Deepak Ravichandran put the reasoning plainly, that "while releases will be more frequent, their smaller scope minimizes disruption and simplifies post-release debugging". Chrome 153 branched a week earlier than it otherwise would have and lands two weeks early. Chrome 154 is due 22 September.

Mozilla beat them to it by a week. Firefox 155 shipped on 1 September, moved up from a planned 15 September, and starts the same fortnightly cadence on desktop and Android. Mozilla is more openly tentative about it, calling the schedule an experiment it may reverse, and warning its own support and translation volunteers that the pace is a real burden. Both companies stress the same caveat: this is not twice as many features. Mozilla's wording is "this doesn't mean Firefox will ship twice as many features". Completed work simply reaches you sooner instead of waiting for the next monthly train.

For a home user that is quietly good news, and the reason is Chrome's own year. Six separate Chrome flaws have been exploited by attackers before a fix existed in 2026. In that world, the number of days between a fix being written and a fix reaching your laptop is a security setting, whether or not anyone calls it one. Businesses can still sit on the eight-week Extended Stable channel, but Google now recommends the two-week stable as the safer choice even for them.

One thing does not change. A browser downloads its update quietly and then waits for you to restart it, and a Chrome window left open for three weeks is running three-week-old code. If you are the sort of person who never closes anything, Tendvane's app-update tool reads your installed programs through Windows' own package manager, winget, and shows you in one list which ones, browsers included, are behind.
