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

Hi All,

I would like to hide the "New Tab to Right" option on the Tab Context Menu, and also remove the separator line right below that menu item.

The first line in the following code removes the Menu Item, but none of the 4 remaining lines succeed in removing the separator line. It remains at the top of the menu (see attached image).

Could anyone suggest some code to also remove the separator line at the top?

This is in FF 135.

Thank you.

#context_openANewTab,
#context_openANewTab + menuseparator,
#context_openANewTab_separator,
#context_reloadTab_separator,
#context_reloadTab + menuseparator::before {
   display: none !important;
}

This code below removes the first menu item and ALL separators from ALL menus, which is "ok" but not optimal.

menuseparator,
#context_openANewTab {
   display: none !important;
}

This solution provided by cor-el a few years ago appears to no longer work (the separator remains): https://support.mozilla.org/nl/questions/1340761

How do we convince Mozilla to add dark mode? It's a simple thing, and quite popular today.

I'm referring to Firefox on Desktop, but on Android, before the dark mode revolution, I would to root my phones to control the silly bright screens - it was a lot of work - but worth it. I still avoid apps that refuses to comply with popular and sensible dark mode.

The bright background fixation is due to people growing up writing on white paper... they don't get that it's silly - staring at a flashlight - or 1920x1080 flashlights. I started computers in command line days - dark was default. Then came blinding Windows - many years of blinding nonsense. Finally, in the last 10 years, while most tech has enabled dark mode, MOZILLA is a huge disappointing exception. Why?

The only way I've found to fix Firefox decreases security! about:config, extensions.webextensions.restrictedDomains ... not recommended!

Is there a working way to move tabs to bottom currently?

This was working until the latest Firefox update and I do not specifically remember how I had changed it last time but I believe it was via the about:config settings page but I no longer see such an option there. I tried achieving this via 3rd party plugins/extensions for Firefox but not a single one worked for the current version of Firefox. I even tried using the UserChrome.css file, as I found an article about this in the forum but it did not work either.

In the attached screenshot I have shown what I have currently and what I used to have and wish to set again if possible.

OS: Firefox version: 136.0.4 (64-bit)

I just noticed this today when my browser updated to 136.0.1 (64-bit).

In the Picture attached you can see the tab width changing when playing any audio that brings up whatever that audio symbol is officially called. This also happens when you mute a tab. When unmuting a tab or stopping audio the tab goes back to the regular size.

Is there any setting in the about:config that could stop the resizing of the tab or any setting at all to not have this happen?

Additional info: I have set browser.tabs.tabMinWidth to 140 in about:config. This setting has been this way for years and those tabs with the audio never resized until today.

Dear sir or madam,

Can you please help me with a deeply frustrating problem I'm having with Firefox? After the last update, the shortcuts on my FF homepage disappeared and I can't restore or rebuild them.

Under settings, the homepage is set to show two rows of shortcuts but none are visible. I changed it to show more rows, closed & restarted FF, but no shortcuts appear. I then changed it to no rows, closed & restarted FF, then set it back to two rows, closed & restarted FF - still no rows. I've tried starting FF in troubleshoot mode, but to no avail. Looking through the Community Forums, I can't find anything that directly relates to my problem. In case this may help, I've had this problem once or twice before but I'm afraid I can't remember how it was resolved or if it was anything I stumbled upon that fixed it.

The environment is FF version 136.0.2 (64-bit) on an Acer Aspire E5 PC running Windows 10 Home, 64-bit, version 22H2, last updated 16 March 2025.

If you can offer any suggestion how I can resolve this and stop me pulling my hair out (in my case, it's an endangered species!), my remaining hair and I will be eternally grateful.

Yours faithfully, Peter Palmer

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?

I want my bookmarks toolbar to be across the top of the page but I can only find it from the 3 bars at the top right of the screen. When I click on it, I am given the option to hide the toolbar, but it's already hidden. I have also navigated from the View menu as well, and the toolbar is set on Always Show. I have run out of things to try. I am on a laptop with Microsoft Windows. Can someone offer assistance?

DELL's new monitor, U3225QE, can be connected via Thunderbolt 4. I can display 120Hz and Edge and Chrome display without any problems. Only in Firefox there are some areas that should be displayed in white but are displayed in pink. By the way, when connected via HDMI 2.1, the display is 120Hz without any discoloration. If you turn on the dynamic refresh rate, the screen will go black every time you move the mouse. When it is OFF, Firefox browsing does not change color and can be used normally, I called Dell support and they told me, "That's probably a problem with Firefox." By the way, the hardware configuration is CPU:AMD Ryzen7 9700X Mother Board:Asrock B650M HDV-M.2 Video Card:Asrock Radeon7600XT Challenger 16GB OC Thunderbolt 4 Expansion Card: GIGABYTE GC-MAPLE RIDGE It would be helpful if Mozilla could address this issue.

Since the last update, my bookmarks sidebar does not open automatically when I open Firefox. A minor annoyance, perhaps, but an annoyance nonetheless, especially since it used to work until Firefox monkeyed around with it unnecessarily.

Every help I've found gives the same answer: Make sure the Bookmarks Toolbar is checked "Always Show." Well, it is checked, it was never unchecked, except that I tried unchecking and rechecking it in the vain hope that it would jumpstart something.

Is there any way to fix this? Or is it cursed forever?

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

So, I just now installed Firefox and now I want to change the background of the home page (new tab), the same way you would do in chrome. I did some research and created a chrome folder and a chromeContent.css file in there.

I tried first the code in this link: https://support.mozilla.org/en-US/questions/1271362 and then this one: https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

neither of those worked, even though I'm pretty sure I followed all of the instructions correctly. help please, will be greatly appreciated (i don't know if i chose the correct topic)

Hello,

My experience with Firefox has been great for more than 15 years. However recently there's been a trend of adding new functionality without asking the user whether they want it or not. Moreover, some things cannot be disabled even if I try hard enough.

It was an unpleasant surprise to discover that "This time, search with" panel was removed without my consent, and is now replaced by an extremely inconvenient button. I firmly believe that this is not how UX design is done, and whoever made that choice needs to reevaluate their decision.

How can I revert this change besides rolling back the browser version?

The setting "browser.urlbar.scotchBonnet.enableOverride" did not help, it reverts to *true* on every restart. I have not been able to find any other settings, and I believe that this is not something that a user should do their research on.

Is there a way to affect this change?

Since the 135 update, the pinned shortcuts on the new tab are now not centered under the search bar. I've found a temporary fix in about:config (see below) but this makes the icons incredibly small. I would just like the pinned shortcuts to be centered now instead of left adjacent.

browser.newtabpage.activity-stream.newtabLayouts.variant-a browser.newtabpage.activity-stream.newtabLayouts.variant-b

Does the recent update Firefox 137.0 retain the separate address bar and search bar? One of the things I hate about MS Edge is that there is no separate search bar. Have not been pleased about the small size of the Firefox search bar the last few years. The user should be able to size it at will.

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.

Just recently, the Bookmarks sidebar quit appearing automatically when I opened Firefox. In each new window, it can be selected manually.

I posted this thread under "Privacy and Security" because other threads on the Internet (some quite old) say this issue can be fixed by changing the Browsing history settings. I tried that, but got a strange result: the Bookmarks sidebar did appear automatically, but the webpage I was on would not display any images embedded in the page. And then I wondered: why must I eliminate Browsing History just to automatically display my bookmarks?

Any help would be deeply appreciated.

Firefox 137.0.1, how can I make the scroll bar wider? I tried modifying 'widget.non-native-theme.scrollbar.size.override' in about.config but setting it to 40 made no difference.
