I like to use access keys via context menus sometimes, but when I right-click on the Spam folder, both "Search Messages" and "Empty Spam" have "S" as their access key, so I can't just hit one letter to empty spam. ... View more

We desperately need the option to have mail marked as having been read when it's deleted or not having it marked as read. This has been suggested before but no option has ever showed up. If I delete hundreds of emails, and one was deleted by accident without having been read, it's so much easier to find it in my deleted folder if it's still marked as not read. Even if I accidentally delete something and then undelete it's marked as read even though I never opened it. We need the option of working one way or the other. ... View more

One of my favorite extensions in Chrome was the ability to double click a word and it would give a pop-up with the definition. I have not found any extensions like this for Firefox (at least ones that work).  ... View more

The "URL Filter" field on the DevTools Network tab accepts certain keywords to allow filtering by values other than the URL:         A list of those keywords can be found here. Many of the keywords correspond exactly to the column headings displayed on the Network tab, and those that don't at least begin with the same letter as the column heading, so that, as you type, the input hint guides you to the correct keyword. The one exception is the keyword "mime-type", which can be used to filter by values displayed in the "Type" column (which originate from the "content-type" response headers). Since typing neither "type" nor "content-type" into the input field results in the necessary hint to reveal the actual keyword ("mime-type"), I find myself having to keep revisiting the documentation to find the keyword. Having a keyword alias "type" for the "mime-type" filter keyword would help alot. (i.e. being able to enter either "mime-type:text/html" -or- "type:text/html") ... View more

When I'm browsing in private mode and I reset the app by swipe-closing it on iOS, the app should completely reset to normal browsing. The problem right now is I'll swipe-close the app in private browsing and every new tab that opens from a clicked link will still open in private tabs, negating any logins I have. ... View more

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you. Idea/enhancement request opened based upon Mozilla Support discussion. ... View more

Hi everyone! I often use Firefox windows for websites like WhatsApp or Telegram. These websites are not really just “regular websites” but rather full-featured, semi-standalone web applications. It would be incredibly convenient if, for such windows, I could hide (remove) the navigation toolbar with the back/forward buttons and the address bar, so that only the website content remains visible. F11 does something close to what I want, but it switches the window into fullscreen mode. Would it be possible to add a button, menu item, or shortcut (for example, Shift+F11) that hides all browser UI in the window without going fullscreen? ... View more

Currently, empty lines at the end of signatures are removed. But these lines may be helpful to add some space between the signature and the quoted email, if the signature is placed above the quoted text. Without extra lines, there is almost no space between the new email and the quoted text. ... View more

I use four windows, with many tabs in each, for different purposes. It should be helpful if each background of the windows were of a different color, to identify in what window is the current tab (specially when I use the "search tabs" tool). Using many tabs is not a mistake, is necessary to who work on web.       ... View more

When saving messages to disk (or dragging&dropping them) it can be extremely useful to touch the date and time of the saved messages to the date and time of the original email message. This feature allows you to maintain the chronology and properly sort messages also on disk. ... View more

To make the experience smoother for users of different computer generations. We would like to give users the ability to select the "Prefer hardware accelerated codecs" option in performance browser settings. The idea is simple: Firefox will first select the codecs that are confirmed to be hardware-accelerated for the user's computer. Today, Google YouTube tells browsers to use the AV1 codec with high priority. And browsers follows this, despite the fact that VP9 and AVC codecs are also available.  We can change this to ensure smooth playback across diverse hardware configurations. The goal is to ensure smooth, seamless playback for all users by effectively adapting to the specific hardware acceleration capabilities of each machine.  Let's vote to change how Firefox prioritizes codecs that will unlock the full potential of hardware acceleration for everyone. Let's change the default behavior so more people can enjoy the pleasure of using Firefox. Let's provide this opportunity to all users. ... View more

Firefox is the biggest consumer of my RAM. With RAM prices being ridiculous high at the moment it would be nice to look for other options Many people who have bought more expensive notebooks have dedicated GPUs, but most of the time you are not using this GPU and the VRAM connected to it. There are usually many Gigabytes of VRAM available. It is easy to read and write to VRAM using the OpenCL interface supported by every dedicated GPU. It would be very useful to offload the RAM being used by inactive tabs to VRAM so more RAM becomes available to active processes.   ... View more
