Hi,

I recently set a custom background image for the Firefox new tab page (and possibly the homepage), but now I’d like to remove or replace it.

I’ve already tried:

   Going to about:config and enabling the following:

       browser.newtabpage.activity-stream.newtabWallpapers.customWallpaper.enabled → true

       browser.newtabpage.activity-stream.newtabWallpapers.ui.enabled → true

   Searching for a gear icon or any UI options on the new tab or homepage – but nothing appears.

I also checked about:preferences#home but there are no visible options to manage background images.

How can I remove or change the custom background image? I’d appreciate instructions, config paths, or a file location where I can delete the image manually.

Thank you! p.s. I'm stuck with a background image that makes my shortcuts unreadable and it's driving me crazy. 😅

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 !!

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

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 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.

Good afternoon. Yesterday I updated the Mozilla version from 135.0.1 to 136.0 and now the Firefox logo has appeared on the main screen (where the shortcuts are), thus reducing the size of the shortcuts and creating the inconvenience of having to scroll with the mouse, because before that everything fit nicely. Please remove the logo from the Firefox home page. Or tell me how I can return to version 135.01 without losing my data. This is very inconvenient, so much so that I decided to write to you for the first time.

how do I change weather widget position to left side of Firefox homepage? It was always on the left side and I ran an update this morning and now it is on the right.

I have a Firefox icon on my Windows11 desktop, Start, and one on the taskbar. If I click one either the Firefox icon on the desktop or Start I will get another icon on the task bar and I can do this over and over on my personal desktop getting many Firefox icons.

I just purchased a new Dell Windows11 desktop and have installed Firefox. I set it up just like my personal desktop and have icons on the desktop, Start, and taskbar but every time I click the Firefox desktop or Start icon I don't get a separate icon in the taskbar but they pile up behind the original Firefox on the taskbar. If the cursor hovers over the Firefox icon then I can see the multiple Firefox homepages that I generated.

I have searched for an answer to this problem but have been unsuccessful. I would really appreciate some thoughts on this issue. Firefox has been my one and only browser for many years and I love it 99% of the time, just not this one time. :-) Thank you in advance. Chuck Hall

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

Some extensions, like Bitwarden or Notes, seem to have added their own shortcut icons between the settings cog and the other functions below the tabs, with seemingly no way to remove them? I already have them in my regular toolbar / extension overflow, which has much more space available, so I don't see the point of why there's duplicate ones in the sidebar taking away tab space?

I am so tired of the stupid banner popping up every time I put something into full screen, that says "press escape to exit full screen".

Is there a way to disable that?

I am on a windows 10 PC.

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?

Why is this font so small, I have tried everything so much so that I have the about.config on my bookmark tool bar, I have tried the extensions that do not work, zoom makes everything too big, increase the font on my desk top. When I go into the about.config ....To increase the font size in the Firefox address bar, you can modify the layout.css.devPixelsPerPx setting in about:config or edit the userChrome.css file to apply custom CSS rules none of this works. as you can se from the picture the font is SUPER TINY!!! I have changed the setting on my computer for the desktop also and nothing.

Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you 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?

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

I cannot make fire fox work at all.for me. I need the file, edit, history, bookmark tool bar back. I'm pleading with you. Please I BEG you to uninstall the upgrade. Please let me have the Firefox I had last week. I,m 88 and will die before I ever!!!! i can't make anything work.I have over 5,000 bookmarks. I write for a few dollars to partly support myself. Right now I'm out of business. Where is the invisible email address? I have been using FIREFOX since it came out. i can't go through your circus. A browser should have a high degree of instinctive coordination, it shouldn't be similar to experts cryptic calculus level, when your totally unfamiliar with the level of calculus I'm sorry, I won't be able jump through hoops..

Just purchased a new desktop that came with Windows 11 pro installed. I don't like it. Also having to start from scratch is annoying having to redo all the fixes to Firefox I did on the old computer anyhow.

The attached shows the Toolbar drop downs and what I have done to get rid of them of course the "Show an image preview when you hover on a tab" does just that but the description box (see attached) is still there.

OK I have Firefox 134.0.1 (64-bit) as mentioned Windows 11 pro Any help please and please keep in mind I don't understand a lot of computer speak I am 69yo but can do a bit.
