Firefox Support Forum

I have been a "light theme" user for 15+ years. Since updating to 96.0 today, a dark mode spreading across Firefox has been forced onto me, including:

• New tab background
• Background of any tab waiting to load a page
• Google/Youtube background
• Settings/add-ons/password menu backgrounds
• Automatic username/password drop-down background
• Background of the little box that appears on the bottom-left (the one which shows the URL when you mouse over a link)

I am unhappy with this and wish to have my usual theme back. Can anyone please assist?

(In addition, there is some sort of white border around the current tab, which I do not like)

After new 96.0 update today, browser changed to white on black background; always had the opposite. Can't see method to change back. Setting in font section still says black on white, to no effect.’ Don't want the white on black.

I use Kaltura to record lectures and post them to my course at the U of Utah on Canvas. This semester, Firefox will not allow me to open "my media" where the Kaltura recordings are posted on Canvas. I get the following message: It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve this issue, please update your settings to allow 3rd party cookies.

I copied the Kaltura web address 670542.kaf.kaltura.com that I can see in Chrome and pasted it into a Chrome browser and it goes to my recordings in Canvas when I use Chrome. The same site doesn't work in Firefox. How do I unblock Kaltura third party sessions? Thank you.

Suddenly the backgrounds to many Firefox screens - browser, history, settings - changed from white to black. This makes it very difficult for me to read whats on these screens. How do I change them back to white?

The browser screen was black and I did that "about:config" thing and toggled the "browser.proton.enabled" to False which converted the background of the browser to back to white but all the other drop down menus are still black. The bookmark toolbar menu is black, the background of the hamburger menu is black, and the "customize menu" background is black. These areas are now difficult for me to see.

When FF developers start fooling around with colors in the FF browser they need to tread lightly and be aware of all accessibility problems their users may have. Where accessibility is concerned, one size doesn't fit all. Some people have problems with white backgrounds and others, like myself, have problems reading screens with black backgrounds. One simply MUST be aware of sight problems in users.

P.S. I tried uploading photos of the black backgrounds in question but the upload wheel just kept spinning. The photo size was within accepted parameter. Also, I tried to check the box "Email me when someone answers the thread" but that wouldnt work either.

Attached is what happens when I try to go on reddit. I have no idea what is happening. I was using it just fine 10 minutes ago. I restarted my PC, firefox, opened reddit on chrome. Nothing has fixed it and I have no idea what's going on

Hi, We currently connect to a vendor devices admin page that is inaccessible via Firefox because of the following error "Secure Connection Failed" (Error code: SEC_ERROR_INADEQUATE_KEY_USAGE) and won't present the option to proceed via the "Advanced" option. Long story.... The vendor is aware of the issue and as the configuration page is always accessed internally and uses TLS in some form they do not want to allow us to make any changes to uploading our own certs.

Anyway recently I was made aware of a keyboard shortcut to force firefox to bypass the error screen and force a connection, however I have not been able to find it since on the Shortcut guide for firefox. Can anyone provide me with this shortcut, It will save having to switch between multiple browsers.

Thanks is Advance,

The themes I use normally have white backgrounds and black text. Following an update, the default colour scheme changed from a white background to a black background for web pages without the theme being changed. Google, YouTube, and Firefox pages are all using black backgrounds. I ensured that the Dark theme was disabled, selected the Light theme, then switched back to the theme I had been using; the black background returned when I switched back to the theme I wanted to use. I tried changing the colour settings under "Language and Appearance: Fonts and Colours: Colours..." to white text and black background and back to black text and white background, but no change was noticed at any point.

How do I change the page background back to white?

I updated to the latest version yesterday and now my Bookmarks ,History and a few other things have gone into Dark Mode. I really don't care for it and have tried looking into my settings but I see nothing that I can do to go back to the normal white. I am using Windows 11 on an HP All In One Desktop computer. Is there anything I can do to revert back to the way it was? Thanks for any reply.

bold textThis is 2021. White-on-black is NOT an acceptable DEFAULT theme for our favorite browser.

Thank you very much in advance

I have a custom theme on Firefox called Charlies Red. Up until two days ago, Firefox would always consider it to be in light mode (which I prefer) whenever I'd use it. Now, however, it's in dark mode, and the only way I can return to light mode is to give up my custom theme and instead choose Light as a theme, which I don't like as much as Charlies Red.

Is there a way to force light mode on regardless of which theme I use? One source said I could go to about:config and create a ui.systemUsesDarkTheme number, setting it to 0, but I tried it to no avail and so deleted the number.

I used to be able to have a custom theme and have system pages (home, settings, etc) be black - dark theme - but now the system pages are white - light theme. Is there any way to change system pages colour back to black and keep a custom theme?

Thanks.

Suddenly and while Firefox was open I lost access to Reddit, all it now shows is a black page with the word "Blocked" in it. I've disabled addons, tried a Private Window and am about to do a cache flush. I'm not banned from Reddit, I can still log in on Edge and on Android apps no problem and Reddit seems to be the only page that is having this issue. There doesn't seem to be a ban or block list in Firefox that I can find, I'm at a loss as to why this has suddenly happened.

All of a sudden I have started getting "Secure Connection Failed" (see attached) on way too many websites. I have not changed ant settings or software on my computer. Please tell me this is something Firefox knows about and is fixing.

Yesterday, before I received the update, my Wowway.net email was working as it should. After the update it would not let me log in. All I get on the email login page is Please Wait While We Are Logging You In. This happened on 2 laptops and a desktop. My Wowway.net email is working properly on Chrome on all 3 computers.

We are able to open website on previous versions older than 96. and facing below issue .

The page isn’t redirecting properly. This problem can sometimes be caused by disabling or refusing to accept cookies.

Also we check solution and applied as per your help portal but still facing same difficulty , please help regarding this .

I can't log into wowway.com email in Firefox, but I can access my email in MS Edge. I'd rather use Firefox, as I do for everything else. I have turned off the enhanced tracking protections and turned off my ad blocker and my anti-tracking add-on from Disconnect, and it still won't work. I had this trouble earlier today when there was an internet outage in my area for my Wowway internet service, but after service returned I was able to log back into their system and open my email.

Now, I can still log into their system for my account, but when I click on the "email" icon, I get a message that says "attempting to log you into your email now" and something flashes in the bottom, left corner of the screen and my email never comes up. Normally, this message does not appear and I go right to my email account. I have also unplugged both my router and modem, waited 30 seconds and powered them back up. This did not fix the problem.

Any suggestions would be very much appreciated.

Thanks,

Andy

I'm very sorry if it comes off as hostile. It's actually kind of out of fear that one day it will all break down.

As person on autistic spectrum I really need ability to maintain pleasant-to-eyes user layout. Even before the Quantum updates Firefox moved from pretty much perfect-looking browser to worse and worse (kinda Chrome-looking) one. That's why UserCss was a godsend.

http://prntscr.com/26cyw7p

But every few updates stuff breaks and I have to download yet another updated version of custom CSS, and often at least one option I am using actively is no longer available because firefox update broke it for good. Today was such day - after Firefox updated, suddenly tabs were way too high, extending into favorites tabs. After updating and reconfiguring (since config files are different with each iteration), four more customization options gone in between last and current CSS update.

I understand going forward and such, but if the visuals peaked in 2007, why not keep all the CSS working properly when doing so? Just do not remove old calls and such?
