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.

After the most recent update, all of my Firefox tabs, bookmarks, and general UI fonts have gotten larger. Is this intended or a bug? There are not options that I know of to reduce the size of the fonts to how it looked previously either.

Hi Please could someone help me re-order my firefox toolbars. Previously I managed to arrange them in the order I prefer, but an update seems to have destroyed the order again, and I can no longer find the web page which explained how to do it. reading from the top, I would like to see: • Title bar • Menu bar • Navigation toolbar • Bookmarks toolbar • Tabs toolbar • Web content area

Instead I have • Title bar • Menu bar • Tabs toolbar • Navigation toolbar • Bookmarks toolbar (I even seem to have lost this now and don't know how to get it back!) • Web content area Thanks for any help that can be provided. Brox

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

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!

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.

Firefox mozilla recently updated, now the bookmark side bar has made the fonts dark on a dark background, now unreadable. How do I change the fonts back to white on a dark background?

I just updated Firefox and the bookmarks on the left become all black. Black font on black background. Unreadable. Before that, the font was white.

How do I change that ?

Thanks !

Reference: Firefox Desktop 139.0.1. See the attached image. What does the overlaid blue (cable with plug?) icon mean on top of my Grid Overlay bookmarklet? The overlay appeared after the update to v139.0.1 (desktop) on Arch Linux. And only on top of my bookmarklet. In case it's relevant. The bookmarklet consists of JS that injects some HTML in the rendered webpage and then beckons my grid overlay. Self developed to overlay my own web layouts.

I recently needed to reinstall Firefox to attempt to deal with an issue. It turned out Firefox was not the cause but when the new browser opened, it did not have the Home icon on the toolbar.

I went to "Customize toolbar" and added it but now it shows up on the far right end of the toolbar. It used to be to the left of the URL area. I tried to grab it with the mouse and drag it but it won't move.

Every time I need to jump to a home page I end up going where it used to be. I realize this is small potatoes but is there any way to get it back where it used to be?

Until recently (like last week-ish) My Bookmarks Sidebar ONLY showed bookmarks. NOW, within the past few days the "bookmarks tools column" has been added to the screen-view. I have removed the 'tools' but the 'blank column' remains and takes up noticeable space on my laptop screen. How can I remove that 'column' ? Was this caused by a recent firefox update OR a win-365 'auto-update' ? Attached pic of screen - Here at the LEFT side is the 'blank column' with the 'settings Gear' at the bottom of the column. That is the column I want to 'Remove'.

I want to turn off a recently added search bar icon in the new version of the newest version of firefox ? I only use google and don't have other search functions enabled but i dont like seeing this icon that suddenly appeared without warning ?

It is too distracting.
