Just did a Mozilla update and noticed the Incognito Mode isn't working the same. I can click a link to New Private Window, but it looks exactly the same as a regular window. Incognito Mode was always purple which help me know I was in that mode. Anyone else notice this? Any suggestions? Thank you in advance.

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?

Hi - Recently when I was on either my desktop or laptop I saw a notification that the sidebar would be going away. I can't seem to find any information on that now though. Will the sidebar still be going away soon? I for one would like to say that I enjoy that feature and would like to see it stay an option on desktops/laptops. If it does go away, how do we access bookmarks and synced tabs? Is there anything I need to do ahead of it possibly going away? Thanks in advance for your help!

The Firefox icon looks like it has a shopping cart on the top-left hand side. What is this for? It is only happening on the Windows 11 taskbar (not the desktop or menu shortcut).

I've recently noticed that the minimize button on the top right of the screen is missing, all I have is the close app button and a drop down. I'm on Bazzite, I have the sidebar disabled, I've already done a refresh. The only thing I really haven't done is a full uninstall then reinstall, but I wanted to see if there was a setting I missed anywhere. I've attached a screenshot of the drop down and close app button, but no minimize.

As I said I opened my browser and ff said they were going to have a new bookmark system did I want to try it...I clicked yes and now everything has changed my tabs are now on the side rather than on the top...my bookmarks are now longer readily accessible. I'd like to get back to where I was...or at least find a tutorial to show me how to navigate the new configuration... Help

Greetings...

I successfully deleted the new weather widget that appears at the top right of my Firefox homepage but the horizontal space at the top of my homepage remains. I followed all of the steps (3) to delete the weather widget but none of them also deleted the horizontal space. As a result, there is a wide white top "margin" that appears on my homepage, below which the customary Firefox graphic logo appears.

On my Firefox homepage, I have three rows of shortcuts that now appear lower on the homepage and a vertical scroll bar now appears on the right side of the homepage. Before the new weather widget appeared on my homepage, the three rows of shortcuts were vertically centered on the homepage, without the need for a vertical scroll bar to appear.

Either there is a way that the horizontal space at the top of my homepage can be deleted, or I will have to resort to creating a custom HTML webpage containing my shortcuts.

Please advise which solution will resolve this problem. Thank you very much for your time and feedback.

Take care...

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'm on Debian 13 stable with firefox nightly (tarball) downloaded from the firefox website with firefox running on wayland. I don't recall the exact time / build that this issue happened, but it has been persistent for over a week or two already.

The issue I am seeing is where secondary menus or popups do not scale properly in firefox. This includes Popups for extensions, right click menus, or even link previews (long click left mouse btn).

<See screenshots>

Things I tried with no luck:

• Restarting my computer
• Restarting firefox / Updating firefox from the firefox website (https://www.firefox.com/en-US/channel/desktop/)
• Changing my display scale (100%) to (90%)
• Changing firefox display scale from (130%) to (100%)
• Refreshing firefox through the settings (aka clearing extensions and all the other stuff)
• Switching to X11 and back to Wayland... X11 worked fine, but back to Wayland just got things borked again
• Updating all system packages on Debian (nothing much except for security updates on debian stable)

Now the questions I have:

1. Is there a way to fix this issue? 2. Where could I file a bug for this issue? 3. Are there other people with this same issue?

I am making another plea: how do I change the font size of the working bars in firefox? The Title BAR, the Menu BAR, the Tab BAR, etc. On my computer, they're minuscule, and I can't see them. I'm not a programmer, I don't know anything about code, so that limits the way things can be explained to me, or that I can understand. Several of you have been kind enough to suggest different solutions, but they all make things worse. I think I've screwed things up almost irreparably. I can barely recognize my browser any more. I've even tried to refresh Firefox, and that also made the situation worse. And now, every tab crashes constantly. Thanks to anyone who can help me solve this problem.

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.
