Firefox Community Forum

Hello! Please report this bug to the developers. When I first launch Firefox after turning on my computer, the window title bar and buttons in the upper right corner (like "Minimize," "Minimize to Window," and "Close") sometimes disappear. If I minimize the browser via the bottom taskbar and then restore it, these buttons and the title bar appear. I'm using Windows 10 x64, with a screen resolution of 2560x1440 (scaled to 125%, but I don't think this has anything to do with the scale or resolution, as other browsers (Opera, Edge) don't have these title bar issues).

See screenshots at the links: https://imgur.com/a/Hbc9yvE (There are two screenshots: 1 - with the window title and buttons (as it should be), 2 - when the window title and buttons disappear)

I've noticed that if I let Windows sit for a while after turning on the PC (2-3 minutes) and then launch Firefox, the problem with the disappearing title bar and buttons seems to disappear. Apparently, Firefox doesn't have time to load properly after Windows loads, and if I launch Firefox almost immediately after Windows loads, the problem described above occurs. And when the OS sits for 2-3 minutes, Firefox apparently loads all its services and processes normally and then works normally, without this error. Firefox ver.: 150.0.3.

This bug was also discussed on the forum by some other users, and they are also experiencing this bug: https://forum.mozilla-russia.org/viewtopic.php?pid=818805

I would like to make the toolbar and bookmark font larger. When I search for answer it keeps telling me to change layout.css.devPixelsPerPx to a larger number. I have done that a couple of times, and after restarting Firefox the font is still the same size. I search the community and didn't see an answer either, so figured I would ask. Thanks Jack

Hello, I somehow have gotten a slimmer sidebar that is attached to my bookmarks sidebar on the left. I can't get it to disappear without losing my bookmarks at the same time. When I re-open bookmarks it has this sidebar again on the side. Is it possible to get just this slim bar to go away? Thank you

I got a new Samsung monitor and the Firefox tabs and taskbar icons are suddenly tiny. I can enlarge web pages with the zoom function, but can't enlarge the tabs or icons. How can I fix this? Thanks, Alan

Ever since updating to Version 143.0.1 all my custom PNG Bookmark icons for individual Bookmarks and also for Bookmark folders that are inside Bookmark folders on the actual Toolbar, do not show up anymore.

When I drag out a individual Bookmark or a Bookmark Folder out from a Bookmark folder and then place that same individual Bookmark or Bookmark Folder directly onto theToolbar itself the actual custom PNG icon will re-appear and work like normal, but the custom PNG icons for Bookmarks and Bookmark folders within Bookmark folders, no longer show the custom PNG icon.

This problem with the userChrome.css document in the chrome folder which BTW is also where all the custom PNG Bookmark and Bookmark Folder Icons are, was not happening prior to Version 143.0.1

Can somebody please help me out?

Yet again Mozilla have decided that yellow folder icons are not needed and have amended the code so user chrome files no longer work. Is there a new way to return the folder icons to yellow or are we stuck with the black icons with a white frame?

So I just noticed an odd thing today. In the URL bar there is a new icon listed as 'add to taskbar' and 'toggle reader view'. The former interests me more than the latter. I get the idea behind it, but it's not really for me. Is there a way to remove these from the URL bar? I looked in settings, but didn't see anything. So if it's not there, I'm guessing it needs to be fixed in about:config? If so, where do i look for these?

I'm including a screenshot of the icon in question.

I am somehow getting the new letter rendering on Windows 10, most letters are very pale, 't' is bold , tabs pale , looks horrible. I didn't change anything. So, annoying, difficult to read. Please help.

The refresh button in my firefox desktop browser suddenly disappeared. One day the usage was normal, but on the next launch of the browser, there was no refresh button. I currently use the "F5" button to refresh but it would be better to use the button again.

I just moved to a new computer. Still using the latest version of Firefox (145.x). But of course I have a much higher rez screen. So I'm looking at many more bookmarks across the menu bar, and they are all very small. As are the tabs at the top of the window. I can not find a way to make these larger in Settings. Grok tells me to work with CSS in the profiles folder, but that doesn't seem to work. (And I bet that every time a new version came out, I'd have to move or remake that CSS file and/or folder.) Is this just the way it is on the high-rez screen, or can someone point me to a solution?
