I was customizing my background by loading a picture. It's adult in nature. It should be my computer in my in my private home. When something amazing started happening. If I load ANY image with a naked woman on it After a few minutes Fire fox auto removes it. I have done this 30 times. I use ANY fire fox picture it's fine stays there forever. Load ANY picture with a naked woman on it and poof 2 minutes later it's gone. So please can you explain to me why whats claimed to be the most private and secure browser around is censoring me in my own home about what backgrounds I can have? I find this highly disturbing. And I am quite serious I have had them removed at least 30 times. I'm 56 y/o If I want a naked woman on my background it should be my business not fire foxes. Also no chrome is not doing it. neither is windows. It's Firefox removing them. Any explanation would be nice.

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.

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.

I have a vivo pad 3, and when I'm using it in landscape mode, the firefox app would only occupy part of the screen, leaving the two sides empty. It used to work fine and I don't know what made it to behave like this since I didn't touch the settings, and no other app is like this.

1. My left-hand sidebar contained about 150 URL links, mostly not bookmarks. I have used this constantly for the last 10 years to access desired websites. 2. After installing 149.0.2 this sidebar with all links disappeared when Firefox was restarted. 3. I tried several suggested remedies such as changing profile or settings on General or Home tabs. None of these were successful. 4. I have seen a portion of my list twice, enough to believe the entire list is stored someplace. It displayed in a box on the Firefox page, but I cannot remember how I produced this list.

How do I get back to having a sidebar full of links?

macOS Tahoe, Firefox 152.0.3 macOS settings include "Appearance - Auto"; i.e. system switches from light to dark at sunset. While the "top area" (tabs, address bar, bookmarks bar) of Firefox follows this - some of the pages themselves do NOT???

I found this website which was at top of the search results. I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config. I set this to "True", but may have screwed this up!! First question: Should I "reset" this somehow?

Finally: To get at the primary question, there are two "sub-questions" that may explain my confusion more clearly:

1. Is there no ***simple way*** to get Firefox & webpages I view to follow macOS Light/Dark appearance?? What are the CORRECT steps?

2. Do individual webpages have the ability to "decide for themselves" whether or not they will adhere to the system light/dark settings. This may well be an officially "stupid question", but while "most" webpages remain "Light" (including this Support page), a few pages appear dark.

On Arch Linux with the latest version of Firefox, the interface elements turn black due to a theme loading failure. 'This issue persists even when using the default theme.

Going to Settings and disabling the theme (which automatically falls back to another theme) resolves the problem.Re‑enabling the problematic theme does not reproduce it immediately. However, the issue reappears after restarting Firefox.

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?

Thanks,

DC

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..

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 !!

The old menu is more user friendly and everything shows up. Unlike the new menu where you have to search for stuff. Please incorporate an option to choose between menus.

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?

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?
