Hello, does Firefox has a function where the bookmarks only show in a Bookmarks toolbar when a blank tab is open please? Once a bookmark is selected from the Bookmarks Toolbar, then the Bookmarks Toolbar is no longer needed and should disappear to maximise webpage space.

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'.

Hi, is there a way to customize sidebar to move the controls to the top or bottom of the sidebar? With sidebar open there is a lot of wasted space with just 3 icons - settings, history and sideberry buttons. Not really an optimal situation.

Attached screenshot and another picture explaining where I would like to move the buttons. Either top or bottom of the sidebar is preferable than taking the side.

The UI font on Firefox UI appears to be corrupted. See screenshots attached.

The app was installed recently and not used much. When I launched it today the font appears like this. No other apps are affected.

I only have a handful of custom fonts and none overwrite any system fonts.

Hello people,

I have a problem. At the moment I am running a Firefox version 143 on Linux with different windows. At the top left you can then select which windows you want to use. Only now it has disappeared. You get a home page. I have tried several solutions. Anyway, how do you get the rest back? Thanks.

I recently installed Win 11 on a new Acer Aspire (with MSI MAG244F monitor) but the issue seems to be present on my Acer Nitro 5 with built-in monitor as well.

I don't think it's an Acer issue but I am only running Win 11 on the two Acer machines. If I open a web page with colored graphics or pictures and then drop down a menu of the browser (bookmarks, etc.) the colors of the graphics bleed through. It's annoying and somewhat obstructive. It does not occur if a window from a different app is opened on top of the browser window no matter how bright the colors are.

I attached a few edited screenshots to show the issue. The edits are only to cover personal information etc.

The issue seems to be color saturation and does not occur on my other Win 10 machines or in other browsers. Not even the same version Firefox on the Win 10 machines.

Is there a way to increase the opacity of the drop downs or lower the color saturation in the Firefox browser?

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.

Hello,

I am using a website with text input fields in a dialog box. When I open the dialog box (show_modal()), I see the entire dialog box (Figure 1). When I type in one of the text fields, it automatically enlarges (Figure 2). How can I prevent this?

Greetings..

I upgraded with a new cpu and windows 11. When I open firefox, I noticed the "Home" tab missing from the upper lefthand tabbar next to the refresh. Is there a setting that I am missing or is it part of a update that eliminated that feature ?

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.

Mozilla sidebar has been replaced by "Choose an AI chatbot to use in the Firefox sidebar." How do I undo this and return to Mozilla standard Firefox sidebar. Not at all what I want to do. Help

I updated Firefox on my iPhone 16 yesterday. How can I permanently remove the purple coloring from the top and bottom, and restore a neutral white or gray? Is it possible to restore a previous Firefox version on my iPhone 16, or do I have to wait for another update? Thank you.

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 !!
