Firefox 140.0.2 on Windows 11 All localization settings are correct (English / US)

I like to use the Inter font where I can due to its legibility, etc. I've used it as the default font in Firefox for a long time and I have Firefox set to not override fonts. Recently I've noticed some glyphs aren't getting rendered / chosen correctly. This is just one example (a message entry field on a forum) but I've seen it elsewhere so it's not just this page. See the attached images comparing Segoe UI and Inter.

Font issue or Firefox? I'm tempted to suspect the latter since I've used Inter all over the place previously without problems and being a font, once done it's done. I've also not seen issues in places using Inter.

Thanks.

I really need help with a border around my Firefox on windows 10. I've tried every UserChrome workaround that I can find and it may be an issue at the system level. But I've never had this issue on any program.

-This issue is only present on my win10 desktop and not my win11 laptop. -F11 fullscreen DOES fix the issue but I don't really want it in fullscreen. -Displaying the titlebar also DOES fix the issue but I'd like it hidden. -I do have a second monitor, but I unplugged it and restarted FF. It's the same resolution. -It's not a profile or theme problem. It persists on new profiles and reinstallation.

Firefox on my Windows 11 machine does not display a bar at the bottom of the screen. This is a problem when a web page is wider than my display, there is not slide bar at the bottom to grab and pan to the right. I have not found a way to get the bar back. Is this intentional? Am I missing something?

How do I get my default display before I updated to 139.0.4 (64-bit)? I'm on a Mac, and I don't like what it's doing to all of my screens. It's driving me crazy. I want how it used to react. How can I go back to an earlier version?

Prior to FF140 the context menu button labels left placeholders on the left that aligned the labels with extension buttons. Currently the labels moved to the left edge, which is a bit annoying after them being in the same place for years.

Was this a planned change or is this a bug I should report to bugzilla?

Curiously, if there is at least one item with a checkbox (e.g. this textbox) all items return to their old alignment. I find that even more distracting.

Hi Firefox

The sidebar isn't showing the buttons. They are there but I can't tell what is what without clicking on them which makes them useless for a shortcut.

Thanks for any help

Hello, Since the update on 24 June 2025, bookmarks are displayed in black text on a black background. Is this normal? If not, how can I resolve the issue? I had set it to dark mode, but even when I switched back to light mode, nothing changed. I would appreciate help from the community or Mozilla if anyone has a website address to contact them. Have a nice day.

Hallo, ich arbeite gerne mit geöffneter Sidebar und bisher (bis Firefox-Version: 139.0 waren sowohl die Ordner der Sidebar, wie auch die in Ordnern abgelegten Webseiteneinträge immer in weißer Farbe (vor dunklem Hintergrund). Jetzt nach dem Update von Firefox auf Vers.: 140.0 ist der Hintergrund der Sidebar 'dunkelgrau' und die Schrift der Ordner und Webseiteneinträge sind in schwarzer Farbe, sodaß man diese nicht mehr richtig sehen kann; lediglich die Icon's der Webseiteneinträge sind in der entsprechenden Farbe/Logo der Webseite korrekt zu sehen. Liegt das jetzt am Update von Firefox 139.0 auf 140.0 ?? Die Sidebar war bis gestern noch korrekt und lesbar dargestellt !!

I installed the new 140 update, and now when I open the bookmark sidebar, the "Search bookmarks" field is highlighted, and the entire list of bookmarks is darkened to the point that it's pretty much unreadable. This was never the case before. I NEVER use the 'search bookmarks' function. My bookmarks are organized into folders and sorted alphabetically. How can I undo this setting so the sidebar looks like it used to?

Thanks!

Firefox 140 I use Tree Style Tabs for my tabs, and have for a long time. I updated to 140 and now, at the top of the sidebar is "Tree Style Tab X". Clicking X closes Tree Style Tab and the sidebar. My question. Is there a way to not have Tree Style Tabs and the top of the sidebar, but return to "BookmarksHome" which was at the top previously? Appreciate any help or ideas.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

Hello,

Since update 140.0, the side panel is dark (no problem), but the text is black instead of white!!! Which makes reading black on dark is very complicated... Could you fix this problem with a new update? Thank you so much in advance.
