Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below: - One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case. Because the horizontal and vertical screen experiences are different, it is very reasonable to make the sidebar selectable by window! 😄 It brings much more convenience, at least for situations just like mine.

Currently, when vertical tabs is enabled and the user entered fullscreen manually via F11, the vertical tabs bar will not hide. A workaround is Hide tabs and sidebar option in sidebar settings, however it conflicts with Expand sidebar on hover option. Ideally, both the toolbar and vertical tabs bar should hide in fullscreen unless the user hovers on the edge of the screen. Can Firefox add a option to hide the sidebar in fullscreen just like how Microsoft Edge was doing or even making this default? (The current behaviour was observed on Firefox Developer Edition 141.0b9 and I did not verify this on other versions) ... View more

E-Mail was designed without encryption and authentication in mind, so everything that protects us against spoofed senders and being completely open to anyone on the wire and noosy curious server admins, was added later on top. To be blunt, the user experience isn't good. All things you have to opt-in, aren't properly handled by everyones client or infrastructure. Therefore Lavabits Ladar Lavison tried to create a new revised e-mail protocol suite, the Dark Internet Mail Environment, called DIME. (https://archive.org/details/Dark_Mail_specifications_dark-internet-mail-environment-june-2018) It protects meta-data by default and wraps everything in a tor-like set of onion layers. Only the Sender and the Recipient know the full relationship between the two. The sending server only knows the receiving server, but not the end user that gets the mail. The receiving server knows which server delivered the mail, but not the useraccount that send the e-mail. I'd like to see this spec being picked up, standardised , implemented in Thunderbird so we have a modern way to send our e-mails that protects us by default in a similar way to what messengers already deliver.   ...

Add the ability to proxy traffic only for selected domains. Now the browser only has "No proxy for", we need the opposite function "use proxy only for". I want to be able to fully use Firefox proxy together with the CloudFlare WARP client to redirect traffic only for selected sites. In CloudFlare WARP, you can register domains for split tunneling, but this doesn't work because the browser uses DoH (DNS over HTTPS) and ECH (Encrypted Client Hello) - I do not want to disable these technologies. The only thing left is to use the local proxy server function in CloudFlare WARP - in this mode, their client works as a local proxy server (receives traffic from other programs configured for a local proxy) and sends it to their VPN. ...

Firefox is already an excellent browser — known for its fierce commitment to privacy, extensibility, and open standards. But on mobile and tablet devices, particularly in landscape mode, its user experience still lags. This isn’t due to a lack of technical capability, but rather a missing UX behavior that Microsoft Edge quietly nails: orientation-aware adaptive rendering. In Edge, when a device is rotated into landscape, the browser automatically switches to a desktop-style user agent and layout, then reverts to a touch-optimized mobile view in portrait. No manual toggling. No workarounds. Just a seamless, intelligent shift tailored to the device's posture — especially useful on tablets, foldables, and large phones. [Reference: Edge “Touch Mode”](https://techcommunity.microsoft.com/t5/articles/how-to-use-microsoft-edge-in-touch-mode/ba-p/2823914) Firefox already has all the tools to implement this behavior natively - It supports the [Screen Orientation API](https://developer.mozilla.org/en-US/docs/Web/API/ScreenOrientation) (`screen.orientation.lock()`), allowing awareness and control over orientation changes. - It understands [CSS orientation media queries](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/orientation), like `@media (orientation: landscape)`, enabling responsive layout shifts. - It can dynamically adjust internal flags like `layout.css.devPixelsPerPx` and spoof a desktop UA string when orientation and screen size suggest a desktop-leaning UX is preferable. None of this requires a UI overhaul — just smarter defaults that respond fluidly to the way users hold their devices. By implementing orientation-aware behavior, Firefox could instantly improve its standing on touch-first devices - No more manual UA overrides or zoom hacks just to make web apps look normal in landscape. - Smarter, context-aware UX that behaves like a modern, intelligent browser — not a rigid desktop port. - Better accessibility, especially for touch users who find desktop-mode controls too small or cluttered in landscape. - Minimal risk: this could launch as an opt-in feature flag in `about:config`, inviting community testing and feedback the open-source way. Mozilla doesn’t need to mimic Edge out of insecurity — it needs to lead in user-first innovation. And in a world where devices are increasingly hybrid (tablets, foldables, DeX-mode phones), orientation-aware responsiveness isn’t a luxury — it’s a baseline expectation. Making Firefox truly adaptive across orientations and screen classes would complete its feature set not by adding complexity, but by removing friction. It's a small change with an outsized impact — one that would make Firefox not just feature-complete, but experience-complete. ... View more

I don't know if this is implemented on any other browser, or if its implementable at all. But often times I switch between tabs using shortcuts like Ctrl+Pageup/down or Ctrl+Number and am (slightly) annoyed when I have to tab through the entire page just to get to the textbox I need. Is it possible to make a custom keyboard shortcut (like Ctrl+/ or Ctrl+Shift+Tab) on firefox that focuses on either a primary textbox (type=search on sites like gmail) or maybe just tabs through all visible (or present) input fields? that way it improves accesibility dramatically for users without a mouse like me, and would be an innovation that (I don't think) any other browser has. A lot of times browsing is just about reading, and typing, almost on a site with a search box. It's probably possible to implement this with a script on some of those scripting extensions out there since it's  (seemingly) relatively simple (to do in JS), but, is it possible? is it viable? am I alone in this usecase? Should I open a bug report about it? I'd like some feedback if possible. Thanks ... View more

Because relay.firefox.com is now banned in China using google anycast, I can't use such a good feature, but cloudflare anycast can be used in China, and cloudflare's privacy protection is very good, and websites deployed on cloudflare can use privacy-protecting features such as ECH, Therefore, it is recommended to transfer the domain relay.firefox.com to Cloudflare ...

Hello, I'm not saying I don't like the current Firefox design, but maybe some would like to be able to customize the tab bar/icon style/bookmark bar/context menu more than just light/dark and color/image. Maybe some would love a Chrome-like design or even an IE-like design. I don't know if it's a good idea but maybe we could add a setting to choose the design, like this: Different designs of the tab bar Who knows, maybe some rounded corner haters would even want it to look like this 😆 Netscape mode          Nostalgia mode ...

Hi, currently in the tasks there is no practical sorting by priority. The click on priority column gives you either: 1. high priority 2. rand("medium/regular priority" or "no priority" 3. low priority or the other way around. It does not differntiate between "regular priority" and "no priority" tasks. Please consider implementing "regular priority" tasks to be on the second place, and "no priority" on last place. That is the implementation how tasks.org sorts the data from caldav tasks.   ... View more

It would be nice if the Firefox shortcuts actually worked with the sticky keys. I'm not disabled but this could be a real problem for disabled people. Activate the sticky keys, open Firefox, and press and release Ctrl. Now press T: this should open a new tab. You actually have little to no chance of getting a new tab because it will send another random shortcut, like Ctrl+P or Ctrl+E. In my opinion, no sticky keys at all is better than those unreliable sticky keys that randomly decide to mute the tab (Ctrl+M) or to close it (Ctrl+W) when I press Ctrl and then L. But anyway Firefox supports the "normal" way (press Ctrl, press T and release both), and my keyboard is not broken because the sticky keys work just fine in Windows Explorer for instance. Thank you for reading 😉 PS. I use Firefox 139.0.4 on Windows 11 Home 24H2 ... View more

Hello! When you right-click a video player in Firefox, there is a menu which offers the options Read, Mute, Speed, Loop, Full screen, etc... It would be nice to be able to personalize that menu in the settings, to hide options I never use or to add new ones. For example, 'subtitles', 'download subtitles', 'color filter', 'mirror mode (flipped horizontally)' or 'share along with current playback time'. Particularly in the nested 'Speed' menu: it would be great if there was a 0.75x or 0.25x option, or even an option to set a custom speed. Also, there is no menu at all when you right-click on a video in 'separate window' (embedded picture-in-picture?) mode. Final remark: 'Ask [AI name]' seems to be an useless option for videos because it sends a blank selection (same for images). Thanks 🙂 ... View more
