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

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

Using Thunderbird 145.0, I have enabled the option to put a copy of Sent messages into the same folder as the original/source message being replied to.  But that copy is marked as 'Unread' and shows in bold.  I would like to see it automatically marked as 'Read' instead.  (I am usually replying to things in the Inbox, and so then the badge-count and formatting of the folder in the side bar show as having something that is Unread, which isn't strictly true - I wrote it, so I probably read it.  🙂 ) ...

When the sidebar is clicked, it pushes the screen into a different screen ratio, and it also jitters. I want the option for the sidebar to extend out without the ratio changing. Going over the screen instead of pushing it to the side. ... View more

I suggest removing the card borders that make it difficult to read the content and identify unread emails. This will give the text more room and reduce eye strain. While waiting for an official solution, I created a userChrome.css, although it is still far from what can be done (such as improving the identification of unread emails or even could maintain the ​​the blue left rounded border to selected email, currently implemented in TB 145). Overall, it would be better if the user could have more control over the overall appearance, being able to customize these and other visual aspects of TB (maybe similar to Firefox Color). ...

I've recently started using sidebar with vertical tabs. It's very useful. I've one idea which may be improvement. I would like to toggle (view/hide) sidebar on keyboard shortcut.

When managing Bookmark Folders in Firefox one can easily move a Bookmark Folder and nest it inside of another Bookmark Folder by accident without notice!  The mechanism by which this happens is mysterious.   A Bookmark Folder upon which one has operated in someway can somehow become stuck to the cursor then moved to the next folder which one selects for an operation.  This seems to happen during a small percentage of operations, perhaps 5% to 10%.  Once moved one can spend hours looking for the missing Bookmark Folder. The problem of manually searching many or all of one's Bookmark Folders for the lost folder can take hours, and the monotony is terrible.  It is made more horrendous by two problems: 1) One can accidentally move other Bookmark Folders and loose them in the process of looking for an accidentally moved Bookmark Folder. 2) One has the nagging fear that the missing Bookmark Folder was not accidentally Moved, but instead accidentally Deleted, when one had worked upon it to "Sort by Name" This problem, and the problem of accidental deletion of a Bookmarks Folder,  must be corrected to make the use of bookmarks in Firefox a reasonable thing to do for serious purposes.  These problems have probably cost me a man-week this Fall, and some elaborate Bookmark Folder Structures have probably been deleted, not just accidentally moved.. ...

Managing Bookmarks and Bookmark Folders in Firefox it is entirely too dangerous since one can accidentally delete a bookmark folder.    With a Folder is selected during management one can open a Pop-Up Menue to  operate upon it.  Two of the operations which can be performed are:   *  Delete Folder    * Sort by Name These commands should not be adjacent.  When doing extensive maintenance on a big folder structure it is too easy to click on "Delete Folder" when one intended to invoke "Sort by Name"  for the 77th time.   Deletion occurs immediately and irrevocably without any safety interlock.   I recommend that Mozilla make all, or at lease most, of the following corrections:  1) Put a no-op link above and another below the "Delete Folder" command, so that the part of the Pop-Up menue looks as follows:      *** no-op ***     Delete Folder     *** no-op ***    Sort by Name 2) Issue an "Are You Sure?" question if someone clicks on "Delete Folder"  3) Save deleted folders and their contents to a Recently Deleted Folders Section so that they can be restored if they had been deleted accidentally ...

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).

Firefox possède déjà la fonction “Rouvrir l’onglet fermé”, mais elle est cachée dans les menus ou derrière un raccourci clavier. Beaucoup d’utilisateurs ne savent même pas qu’elle existe, alors qu’il s’agit d’une action très fréquente dans un navigateur moderne. Je propose d’ajouter un bouton visible dans la barre d’outils (ou dans le menu principal) pour restaurer rapidement les onglets fermés ou la session précédente. Un bouton clair et accessible rendrait Firefox plus simple, plus moderne, et éviterait la frustration lorsque l’on ferme un onglet par erreur. Cette fonctionnalité est tellement importante que certains utilisateurs choisissent Chrome ou Edge uniquement parce que cette action est plus visible et plus facile d’accès. Firefox already has the “Reopen Closed Tab” feature, but it’s hidden in menus or behind a keyboard shortcut. Many users don't even know it exists, even though it is a very common action in a modern browser. I suggest adding a visible button in the toolbar (or main menu) to quickly restore closed tabs or the previous session. A clear and accessible button would make Firefox simpler, more modern, and avoid frustration when you close a tab by mistake. This feature is so important that some users choose Chrome or Edge just because this action is more visible and easier to access. ... 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
