After today's Firefox update my bookmarks menu now has a black background how can i change it back to a white background with black font? I added a dark theme which changed the bookmarks menu background to a black background.

Thank you very much in advance

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.

Hello,

I am a college professor at University of New Haven, which uses the Canvas online learning system. Within Canvas, we have access to the Kaltura media content system where we can create, upload, and share videos with our students through the Canvas application.

This has worked fine until recently. Now, whenever I try to access my Kaltura media through Canvas, I get the following error 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." (see attached photo for reference)

I assume there was a routine Firefox update sometime recently that imposed stricter restriction on third-party cookies. But I have followed all the instructions here (https://support.mozilla.org/en-US/kb/third-party-cookies-firefox-tracking-protection?redirectslug=disable-third-party-cookies&redirectlocale=en-US), and I am still unable to access Kaltura through Canvas (I get the same error message).

FYI - I am able to access Kaltura through Canvas on Chrome, so I know this is a Firefox-specific issue. But I hate Chrome and want to keep using Firefox!

Is this something you can help me with?

Let me know - thanks!

I've been using Elijah Lopez's Matte Black (Red) theme for months. Recently, I think because I added the ClearURLs extension or some other change, certain websites enter some sort of "dark mode" when accessed.

Websites that do this include Twitter, an independent blog, and Youtube.

The website appears normally with the default light theme enabled. In the second photo, the website appears in the "dark mode" with the black Firefox theme enabled.

I have deleted cookies and cache, reinstalled Firefox, and reinstalled Extensions. I think this problem only occurs with dark themes, and nothing else. The moment I change to dark theme, the problem comes back. It is strange because the dark theme was working just fine for months until recently.

How can I keep the dark theme, preferably the same Elijah Lopez's dark theme, while using websites normally and not in this weird "dark theme" style adaptation?

Firefox (desktop version 96.0.1 64-bit) just updated itself on my laptop. Now, it will not load any pages. I'm sending this message using Chrome.

Please help.

Hello,

I connected my router to my PC via ethernet cable and I want to change the SSID and password but the site router.juplink.com is flagged as insecure. I get this message:

"Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to router.juplink.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. Learn more… router.juplink.com uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT View Certificate"

Please advise.

Thank you, Mlichael Pilger

Hi I am having intermittent email problems especially sending. It gives me a timed out message. It will often do it 5 times, and then send as normal. Then it might work perfectly the next 3 times. But then it starts timing out again.

Its been going on for weeks.

Same server, same settings, same programs, nothing different that I did.

I don't use any firewall except what is built into windows 10 and I have never actually seen it.  

Please explain like I am a 5 year old. I write stories and take pictures and do that reasonably well.

 I am a mechanic so I can swap the power supply fan in a desktop pc in minutes flat.

Software type problems though? Please speak very slow and very clearly.

thanks scott

I tried sharing my screen with audio to my friends in Discord and Google Meet, but my friends couldn't hear anything from my pc besides my mic. I tried sharing a tab in Mozilla and the entire screen, both doesn't work for me.

I was running 91.4, automatic update told me it failed and I should download and install 91.5 manually. So I did. 91.5 became a new install and didn't pick up any data & settings from 91.4, which was still there. I uninstalled 91.5 and it deleted all my 91.4 data & settings, so 91.4 was now a new installation. I uninstalled 91.4, installed 91.5 and restored an old profile (yes I should backup profiles more often!) The big legacy is that I can't click on a file in File Explorer and share it by email. 'No associated program' is the message. (Thunderbird is my default email client). I read that File Explorer can only do this operation with 32 bit apps. Outlook users are being advised to downgrade their 64 bit app back to 32. Certainly I have a 91.5 64bit install (I don't recall what 91.4 was). Can I downgrade? Is 91.5 available in 32 bit?

The tab is large enough, but the font size of tab bar is too small. The font size on tab bar discriminates old people, very age-unfriendly. I suggest to make the font there larger and bold.

1. Firefox apparently disconnects in Wordpress when making revisions to pages. 2. Toolbar in Firefox does not work when the main tab is open (or is extremely slow - hard to tell the difference). 3. Twitter links to threads, articles and embedded videos does not work most of the time. 4. Everything is slower.

I'm using Windows 8 - and have no intention of upgrading as I am gradually migrating to Linux. Should I revert to older version of Firefox? None of this happened with earlier versions.

Thanks

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.

Please I just have read lots of people here with the same problem: I want to get rid of this dark mode and there's no help at all to solve this....how can this be possible? Help me please, please, please !!!!

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

I just updated and FF will not load any https site. I'm on Ubuntu 20.04

Secure Connection Failed

Please help me get my messages back. The upgrade to 91.5.0 knocked them out. I have had this problem with an earlier upgrade. Some, but not all messages, become illegible (not in text form). I would like to go back to an earlier version that does not have this problem.
