Dark Reader works for all sites except for mozilla.org, I think these webpages are over-ridden by the Firefox browser? I saw a couple archived posts recommending global changes for all sites via Firefox -> Settings -> Language and Appearance -> Colors, or to install themes. Neither option would work. I don't want to override all sites to dark globally, that's way to much change, just let Dark Reader change just mozilla.org.

Is there a setting or add-on for firefox (Windows) that will block tracking pixels? My email client hi-lites when present and as I understand they are incorporated within images so I dont down load attached images to reduce them. On their pro version they allow blocking of these pixels. Unlike cookies there doesn't seem to be an option on reception to opt out. I'm not fully clear what harm they do or whether they are session use only and delete on power off. I would rather not recieve them atall. Companies when challenged smokescreen and refer to cookies rather than pixels or bang on about their companys integrity.

Thanks for your help

Update to Firefox (120.0.1) in Linux Mint blocks CNN - its the only site which appears to be blocked. I get a message telling me that configuration of the site is blocking CNN from loading, and goes on as follows.

"" We apologize, but your web browser is configured in such a way that it is preventing this site from implementing required components that protect your privacy and allow you to view and change your privacy settings. This functionality is required for privacy legislation in your region.

We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser). ""

Rather strange, since I'm using Firefox.

In general, I am thoroughly annoyed with the way the Internet experience is increasingly fouled up by various sites implementing "safety" aspects. It used to be fun, now its a crap experience. Firefox is getting bigger, slower, and infested with site 'improvements' which do absolutely nothing for me - Is it so hard to provide a simple, clean, straightforward browser without so many 'add-ons' that its grinding to a halt? Time was software was written for the users, now its clearly written to give software developers something to do. Can't you create a revolution in software and do something useful, instead of "clever"?

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

I am running Firefox v 120.0 (64bit) on Windows 10 Pro version 22H2 OS build 19045.3570 and today Firefox has stopped playing the video track on youtube videos or any video that is embedded in a page. Audio works but the screen just shows a blank field of green. The progress bar will show frames from the video. IF I run Firefox in trouble shooting mode the videos play as normal with video and audio tracks.

I have already refreshed fire fox and uninstalled and reinstalled it but the video track is still a blank field of green in both full screen and small screen modes.

Anyone have any ideas on what configuration setting may be causing this? Thanks in advance, Brocky

New computer, Win 11 and FF 120.0.1 all fresh installed and updated with latest versions. The double line spacing in bookmarks and all other menus is back. There was a fix for ver. 89 with the css file trick, but that DOES NOT WORK with this version. All other options I've run across don't work either. Why do the Mozilla software engineers think it's a good idea to break their flagship application every few years? Rhetorical question, I know.

Does anyone have a user fix that actually works with this FF 120.0.1 version? Something an experienced user can do that is not a programmer. analyst or engineer? I've been using FF since it first came out to challenge Microsoft's IE. Late '90s? I'd like to keep using it but this is too annoying to tolerate.

If anyone can help with step by step instructions, I would be eternally grateful.

I've been trying to sign in to pinterest, duolingo, etc using the 'sign in with google' option since my account was saved there. Whenever I click it, a sign in window opens up as usual, but it only ever shows a blank screen. No matter how long I wait, nothing shows up. I tried clearing cache, and it still didn't work. It worked before, but recently since the past 2 weeks, it became like this and I don't know how to fix it.

I have some extensions on my account so I'll list them out just in case one of them is the one making this problem: -Search by Image -Firefox Relay -uBlock Origin -DuckDuckGo Privacy Essentials -TWP - Translate Between Pages -Ecosia


(Below is a screenshot showing what I mean by the sign in window being a blank screen.)

I've set custom fonts through Settings > Fonts > Advanced, but the fonts I have specified are not being used on any websites even if I uncheck the box that says "Allow pages to choose their own fonts, instead of your selections above". For example, I've set the default sans serif to Source Sans 3, but websites use Arial regardless of the settings. The only custom font I've gotten to work is Segoe UI (the UI font on Windows); all other just fall back to Arial. The problem persists even if I disable all extensions/add-ons. I'm also experiencing the problem for non-Latin scripts; I've tried to set the default Bengali font to Noto Sans Bengali, but websites are using Vrinda instead.

I'm running Firefox version 120.0 on Windows 11, any help is greatly appreciated!

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

OS: Windows 10 1607, FF - 120.0, issue was present for many versions before.
