Mozilla has released Firefox 152 with revamped Settings and faster ways to share web content – plus, a peculiar way to mute noisy tabs.
The update is available from today (15 June, 2026) on Windows, macOS and Linux, as well as for Android and iOS (mobile versions have different features and are not covered in this post).
Firefox 152’s headline change is the revamped Settings page. We knew this was coming as Mozilla’s been teasing it for over a year. The company says the new look offers “streamlined organisation, clearer groupings, and improved navigation for easier customisation”.
Since many users find rifling through their web browser’s settings daunting and confusing (especially as more customisation options get added), this is a welcome refresh. Good design is as much about clarity and logic as it is about simply looking pretty.
But forewarn your muscle memory as the ‘General’ page has been removed and its options moved into relevant areas like Appearance, Accessibility, etc. If you can’t find where a setting is you can use the search bar to locate it.
The new-look Settings in Firefox 152 is visually tied to the upcoming Firefox Nova redesign, which also features lots of rounded corners, cards with thin borders, gradients and white space.
Firefox 152 now makes it easier to selectively disable tracker blocking in private browsing windows. This is useful if an element or part of a web pages looks broken or can’t load with trackers blocked (like an Instagram embed in a news story, for instance).
Linux and Windows users can now copy links from the tab context menu (right-click a tab, mouse to Share > Copy Link) without having to focus the tab first. It works when multiple tabs are selected too, so you can copy all selected links at once.
Firefox also introduces a “Send tab” toolbar button, albeit not enabled by default. To add it, go to More Tools > Customise Toolbar and drag it from the button palette on to the toolbar.
Wondering what that ‘peculiar’ new way to mute tabs in Firefox 152 is? The browser lets you type – yes, type – “mute”, “shush” or “sssh” in the address bar to reveal a button you can then click to silence all tabs in all open Firefox windows which are playing sound.
Convenient? Probably. I don’t tend to keep a cacophony of audio in play, and reaching for my keyboard’s mute sound or pause media keys would be a faster way overall. Options are good – especially ones which enable you to role-play as a librarian…
On the topic of words (tangental segue klaxon), Firefox 152 bundles in built-in spellchecker dictionaries for builds downloaded in Croatian, English (UK), Georgian, Persian, Slovenian, Tajik, Tamil, Tibetan, Turkish, Welsh and Xhosa.
Other changes in Firefox 152:
Plus, the usual clutch of web compatibility and developer-focused buffs. It adds action button support for Web Notifications, supports the-sizing property and adds the unadjustedMovement option to the Pointer Lock API so sites can get ‘raw mouse-movement data’.
Plus, a fresh batch of security patches to keep our collective web browsing as safe as it can be.
No new AI features in this update, but Firefox’s new Smart Window browsing mode is still in development. You can test it as a beta feature by flipping the relevant about:config value on (search ‘Smart Window’ to find it).
You can download Firefox 152 from the official website for Windows, macOS and Linux, with builds available for Intel/AMD and ARM64 devices.
If you already use Firefox, update to the newest version the same way you updated to the last – automatically, in most instances.
On Windows and macOS, updates are come as in-app updates downloaded in the background and applies on relaunch. On Linux, your distro’s package manager will serve up the update. On Ubuntu, that comes from the Snap Store unless you use the Mozilla APT repo.
