I have custom userChrome file that made my history and hamburger menu (application menu / settings) text and distances smaller since Firefox introduced this ugly feature, trying to be cool in windows 10 times. Nowadays even windows 11 brings back compact mode but firefox still uses huge spacing. I just fixed issue with custom CSS and forgot about it. Unfortunately, after updating to FF 151, my CSS is ignored and I am forced to new ugly context menu. What is weird, I still have good small pacing when right-clicking pages, UI elements and when I enter bookmarks. Only places that ignore my CSS are hamburger menu for settings and list under history view. I do not really understand this code, I just copied it from someone else. Can someone help me fix this issue?

After the resent update i had yesterday 19/05/2026 my icons section and the icon have all become smaller, i had studies on and i remove that, and it did not help. It have happened the last year now that every second or third update my shortcuts icon and the space around em get smaller and smaller, now the text under icons are all broken up, a year ago it lined up perfectly and readable with the right place for new lines.

I got so much space on my start page and it keep use less and less, is there a way to undo this smaller size.

Using Windows 11 and got display setting 2560 x 1440, which is not small but no near big neither in today.

when I opened my computer this morning all my firefox tabs are really tiny and there is a box upper right that is showing weather. I am not interested in this and I want my screen to look like before. Why do you keep changing things that work fine and give me things that I don't want or need.

Firefox updated to 151.0 last yesterday and now the background of the search selection box has changed color to white from its earlier setting. I have tried a bunch of things but cannot find the CSS needed to restore it to what it was (it was overridden with an image). The image below shows the new, white, version, and what I am trying to do is restore it so that it is overridden with the same background image as the rest of the header. What is the rule needed to override the background of this new box (the box with the colorful "G" and downward caret)?

See attachment, some sites are not loading correctly at all, which ironically includes the mozilla sign in page. I also noticed it on camelcamelcamel.com. See attachments.

I already tried clearing cookies etc. Unchecking the "allow sites to choose their own fonts" fixes it but obviously I don't really want that disabled. I switched off Chrome recently so I'm already quite disappointed tbh.

I use Firefox as it is one of the last good browsers that isn't chromium based. However, I use it for work and like a nice clean PROFESSIONAL look.

With the introduction of version 149, I see new cartoonish fox icons pop up all over the place. After a little research it appears to be Kit, the firefox mascot.

Let me be clear, I don't hate the mascot, he's cute. But that is not what I want in a browser. I find his appearance and lack of ability to eliminate him infuriating.

I try to run a firefox in a as minimalistic state as possible. Intruducutions of this character, make the browser feel cartoony and childish. Things I despise in an application. I know many people like him, but I would like the option to not have him appear in the application at all.

I was able to successfully remove him from the certificate warning page setting the flag: security.certerrors.felt-privacy-v1 --> FALSE.

However, I can't find other places to remove this nuisance. Take a look at the attached screenshot. Things like this are not welcome without a way to disable it.

Do you have any documentation or instructions I can use to disable this childish nonsense and restore an adult browser again?

Hi - Recently when I was on either my desktop or laptop I saw a notification that the sidebar would be going away. I can't seem to find any information on that now though. Will the sidebar still be going away soon? I for one would like to say that I enjoy that feature and would like to see it stay an option on desktops/laptops. If it does go away, how do we access bookmarks and synced tabs? Is there anything I need to do ahead of it possibly going away? Thanks in advance for your help!

since v150 came out ive been having an issue where i get a flash of white on start up if i have Homepage and new windows as Firefox home with a wallpaper... i have re-installed firefox and tested it as default and it still happens. seems the wallpapers have a delay till it displays properly.

In Windows 11, how do I add the Firefox icon to the extreme top left of its webpages?

When I switch tabs to Firefox, typically using Alt+Tab, I am often unsure at first which program I am in. I have searched Firefox settings, and googled extensively, and there seems to be no way to add the icon back. I believe that it was once there, but I am unsure of this.

Almost every other program places its icon on the top left of its pages. Surely it is possible to do the same in Firefox, which just has an empty space there.

(But I am wrong on the last point, because Edge, which I rarely use, also has no icon there. Surely Firefox does not want to share any problem that Edge has!)

Hello All, I'm just into Firefox. Struggling with two untidy bars across top of screen. Need advice to reduce this to one. I have my Win11 taskbar to the left on my PC. Can't we do something to put current open site in there?

I frequently need to access logs in HTML format from a particular application. I find Firefox more comfortable for this, so I visit the parent path directly in the browser. However, the default sort order is by name; since these are logs, it's more useful for me to list them by last modified time. Is it possible to make this sort order the default when visiting file:// paths?

I've attached an image of what I typically visit for completeness.

Thanks.

I use Firefox to manage an online course. For some parts, I want to zoom in to see detailed diagrams etc. In other parts, I want to see at a glance a simple list of submissions. So I have 2 windows (with their relevant tabs) open. But when I zoom into the first, the other window zooms in, so I lose most of the listing. How do I set the zoom differently in the two windows?
