It should be a must have to group tabs with a right klick on the tab (like it's possible in Google Chrome) and  assign the group with a description and a color. Then you can easily open and close a whole group with multiple tabs in it with just one klick. It would be beautiful! Greetings Paul ... View more

I think there should be a lot of work done to have the profiles working, like for instance making them native and customizable like in Chrome. I think a lot of us are switching over to FF because of Chrome's latest version that doesn't allow adblockers, but there is so much more that Chrome does better which is making this a difficult transition. I created separate profiles, one for work and one personal, and they both have Ublock Origin, however the filters I create don't sync automatically. The only way to do it is to backup/restore, which is very irritating since I am on the same computer and I shouldn't have to copy/paste or backup/restore. ... View more

Not sure why Firefox does this. Please explain if you know the rationale behind this. And if there is no good reason Firefox should stop doing this because it can cause all kinds of headaches when you copy and paste stuff around. There is a config flag for this and it's the first setting I change on a fresh install: `layout.word_select.eat_space_to_next_word=false` should be default in my opinion.    ... View more

I'm often viewing PDFs in Firefox and I use the tab icons to quickly find the right tab, but when a tab contains a PDF it has no icon. This makes it harder for me to find it quickly as I'm looking for the absence of something. Some icon for a tab containing a PDF or just an icon indicating a tab is viewing a local file would be really useful. ... View more

When using Firefox desktop version, there is this glaring issue when private tabs are opened - if normal tabs window is closed before private tab window, you lose your entire browsing session!! I lost 200+ opened tabs so many times I can't count anymore, why isn't Mozilla fixing this, and who thought it was a good idea? ... View more

I really like the sidebar, and I think vertical tabs are amazing, even though really new. I want to make a lot of extensions like "side view" that open a website as a sidebar popup, for example a dictionary. This would be really useful. But currently the vertical tabs are in the same sidebar, so a sidebar popup will be next to the sidebar, which is not ergonomic as it squeezes the main website to the very left. See this image: Instead, 2 options would suffice for this: 1. Allow having the vertical tabs in a separate sidebar on the other side With 2 sidebars this could then look like this. Tabs are one, sidebar is the other. I think this makes sense? As the vertical tab bar does not have the default "sidebar spacer" this also looks really nice, not like 2 sidebars at all. 2. Allow addons to spawn a window on the other side The popular (even recommended!) extension "SideBerry" is basically the same as the new vertical tabs UI-wise. It integrates nicely and works well, at least for now. But with the new sidebar, Sideberry seems to use the "spawn popup window from sidebar" feature so it cannot be displayed at the same time as for example a "SideView" window would, which makes it a pretty bad tab bar. You would need to switch between them which is really bad UX. So if Sideberry could spawn a separate popup on the opposite side, it would look like this: Sideberry in this case would not be launched from the sidebar anymore but from an extension menu, or always shown. I am not sure how buggy that would be, for example the "overlay popup" or the "Orbit" extension covers part of the page and thus does not work at all. So that popup would need to restrict the usable space to render websites, so that they adapt instead of being overlaid. Regardless, any of those 2 features would be really nice! Until then I will stay with horizontal tabs which is kinda sad. ... View more

about:preferences#containers My simple request is to make this list reorderable with drag-and-drop. For example, if I have 10 container tabs, and I add a new one, it goes to the bottom of the list. I would like to be able to drag them around to sort them so I don't have to delete them to change the list. When selecting a new container from the context menu in the tab bar, the order of this list is already respected. This would let users simply change the order without any hassle. Thanks.   ...

Themes are a major reason why I choose Firefox over other browsers and the addition of vertical tabs is great and very welcome! I get that vertical tabs provide more vertical screen real estate, but I really enjoy themes and was wondering if it would be possible to make the height of the theme area adjustable or taller, so more of the selected theme shows when vertical tabs is switches on? ...

It would be great like in Chrome to have a button or a command that can run in the search bar to restart all instances/windows/etc. of Firefox, including different profiles. I created a work and a personal profile, but if I run the about:restartrequired (which seems to be the only option right now), it only closes that window that I am in. ... View more

E-ink screens like displaying high-contrast, static content. Most of them is monochrome. Basic e-ink mode is a cheap feature with: animations disabled smooth scrolling disabled  high contrast skin (theme) - preferably black-and-white I suppose it can he achieved by tuning already existing configuration options and merely requires exposing a friendly switch in settings. Maybe even an extension would suffice. A full-fledged e-ink mode also adds: overriding the content CSS to improve webpage contrast page up / page down buttons (or clickable areas) on mobile To be honest, there are no mainstream browsers optimised for e-ink (as of 2025), while the market is growing (ebooks, phones, desktop displays). ...

E.g. if you have a manual with multiple languages (lots of pages), and you want to save just your native language pages into a new manual. I'm currently using the Save to PDF printing feature, but not sure if it's the same thing, i.e., cropping pages from the original pdf. I have no idea how the Save to PDF works under the hood. Text find seems to work in the new pdf file, so I guess it's at least close enough. Would be easier/faster to have the page range selector (e.g. 1, 3, 5-32) directly in the file save dialog. ...

Once a tab group is made, its mobility is extremely limited. Groups themselves cannot be moved, and we can only move individual tabs from the group's left to the group's right, but not visa versa without adding the tab to the group. ... View more

I recently switched from Google Chrome to Firefox. I do much accounting work and one nice thing that Chrome did was auto-select full numbers (including commas and decimals) when I double clicked anywhere on the number. For example, if I double click somewhere on "234" in "$1,234.56" on a page: - Chrome would auto-select "1,234.56". - Firefox only auto-selects "234". Firefox stops at commas and decimal points. ...

I think it would be interesting being able to open new tabs in inverse order. I mean: 1) When using horizontal tabs:     - Show the "Open a new tab" icon at the left of the opened tabs     - Open the new tabs (when clicking that icon) at the left of the rest of the opened tabs 2) When using vertical tabs:     - Show the "New tab" element above the opened tabs     - Open the new tabs (when clicking that element) above of the rest of the opened tabs ...

  It would improve both discoverability and usability. 1. Discoverability: These features, despite being older than every web browser available today, seem relatively unknown. Unfortunate because it alleviates two problems I think are probably common:    ▶ First: I grew up with myspace and like things to look how I want    ▶ Second: accessibility    ▶ The secret third one: a mix of one and two with built in dark mode that is superior to chromiums invert colors version and any third party extension dark mode. 2. Usability: Since I started complaining about this problem, then discovering Firefox already solved it, then posting how awesome a feature it is, it does seem like (from my terminally online first hand experience) more websites have started preferring the slightly different settings Firefox uses instead of other browsers - but still some that are in between or have a dark mode/high quality accessibility settings built in, or just generally don't work well with the Firefox override (like when filling in forms, configuring display settings for other websites (like this post, for example), etc). Thus, while not super common, I do find myself needing to turn the override off and on somewhat often, and it is tedious to switch tabs and would be much easier if the settings were in the sidebar. I have tried to poke around in the code to see if it was something a non-coder could figure out with the help of an AI but soon learned it was not gonna happen that way lol - but despite that it does seem like something that would be a quick thing for someone who does know what they are doing. Maybe. mostly unrelated but I can't help myself so I gotta mention it: not sure whats up with the settings page spelling it colours before and now colors but thats... interesting... also not sure whats up with the firefox colors extension but I am slightly more than slightly amused the implementation of the windows OS theming on the default Firefox theme is slightly better than what either chrome or edge has lol ...

It would be amazing if Firefox could add an option to automatically delete the history after a certain period, similar to other browsers where you can keep only one month, three months or one year of history. Often, my browser gets filled with sites I've used that have since changed domains, leaving it cluttered with useless suggestions overall.   ... View more
