Firefox 153 Is Here: Native Container Tabs, QR Code Sharing, and Vulkan Video Decoding
This is the last "monthly" stable release before Mozilla switches to a two-week release cadence.
Mozilla has shipped Firefox 153, and it's a meaty one. This is the last monthly stable release before Mozilla switches to a two-week release cadence starting in September 2026, so the team packed in a few headline features on the way out.
What's new
Native container tabs. Containers are now built into the browser rather than living behind an add-on. You can keep separate parts of your online life — work, shopping, banking, personal — logged into different accounts in the same window, while Firefox keeps cookies and ad trackers isolated inside each container.
QR code sharing. Right-click any open tab and choose Share > Generate QR Code to turn the current page into a scannable code — handy for posters, slides, or printed handouts.
Smarter address bar. Typing "pick color," "color picker," or "eyedropper" into the address bar now surfaces a quick action to sample a color straight off the page. Typing "labs" or "experiment" jumps directly into Firefox Labs.
New Tab gets its own address bar. The New Tab page now includes a URL bar for typing addresses or searching, without needing to click into the main bar first.
Under the hood: Vulkan video decoding and experimental JPEG-XL image support have also landed in this release, improving playback smoothness and image quality on supported hardware.
Firefox 153 is also the newest Extended Support Release (ESR), so organizations, schools, and anyone who prefers a slower update cycle can pick that channel for long-term stability.
