How in the heck do you increase the size of the UI font? I have a 1440P monitor and the TINY size of the UI font makes it nearly impossible to read the text on the menu buttons, I have lean forward and squint to read it because they are so damn small. I can't find anything in the settings to make the UI text larger. It is as if some dummy hard coded the UI font size so it's impossible for the average person to find out how to change it. It makes no sense whatsoever.

And please don't tell me to increase the zoom in the Windows settings, because that screws up EVERYTHING else...

Another thing that is driving me crazy is how do you set it so that scrolling with the mouse wheel is smooth and not jerky? When i scroll with the mouse wheel, instead of smoothly moving the page up or down, it JERKS a couple of lines at a time. This is the only browser that it does that in. I have smooth scrolling ON in the mouse settings on my computer but for some reason, only Firefox is doing this.

I just installed Firefox 140.0.4 on my MacBook Pro, and the text size in the tab headings is way too small. I've seen fixes (from years ago) for older versions of Firefox, but they haven't worked for the recent version 140.0.4.

Hello,

How do I permanently show the top and bottom menu bars please ?

I have done something wrong and now the top bar only shows when I move the cursor to the top of the screen and the bottom bar has diusappeared.

Thanks !

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

Hello everyone I just updated my operating system to refresh Win 11 and downloaded a fresh copy of Firefox signed in The problem I am having is when I switch to a theme it does not stay or show in the tabs Has anyone found a solution?

Hi... Funny behavior with Firefox after connecting an external screen. First the technical specs: Macbook Air 13" 2017, Os 10.14.5 Mojave. Firefox 115.25.0esr.

So.. I connect an external screen 800 x 480 pix. Then I go to the screen settings to adjust taht little screen. Now everything looks very big on the computer, so I adjust the computer screen in the settings. The desctopp looks normal again, but not Firefox. All open windows have now been squeezed up in the upper left corner and only filling a 4th of the sceen... strange. Apple support couldn't help. Of course I can drag out this windows again manually, this is annoying. Safari is not behaving this way... Somebody tell something.

Thanks in advance. Jesper

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

When I Hover over the Firefox Icon in my Taskbar, it shows a Thumbnail of the Windows I have open. If I have a bunch of windows it dispenses with the Thumbnails in favor of a Text based Description. I'd prefer it did that all the Time. I don't care much for the Thumbnails. Is there a Setting someplace that I can make Text the Default view ?

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing
