Somehow, the prefers-color-scheme: dark media query does not seem to behave correctly in my browser. I am using Firefox 89.0.2 on Windows 10 21H1 and even though I have set the system theme to dark (which Firefox's System Theme adapts to, the browser UI is dark), websites which usually adapt to it (like YouTube when set to follow the device theme) do not do so and are using the light theme regardless. This issue persists even in troubleshooting mode, so it does not seem to be related to any add-on I have installed.

Testing the same websites on Firefox Nightly (91.0a1) and Developer Edition (90.0b12), they behave as expected, adapting to my system's dark theme. The same had been the case when I had been using Firefox 88 (where it did not work as expected), while websites on Nightly and Developer Edition (versions 90 and 89, respectively) did behave as expected.

Is there some fix for this issue, some setting that is supposed to be tweaked, or can a fix be expected in an upcoming release?

I open the terminal (I'm using FreeBSD) and I run: `firefox --help` and I get a lot of command line options. However there seems to be no way to simply get the user agent string. This is kind of annoying because I might want to plug the current version of my Firefox browser in some automated scripts. At the moment I need to open Firefox, then go to the console and type in: `window.navigator.userAgent` copy the string manually and paste it wherever I want to use it. It would be really nice if there could be an extra option to the `firefox` command, like: `firefox --user-agent` that prints this information in the console. Maybe there's a way, if it is it must be really hidden because I couldn't find relevant information on how to do it.

Kind regards, Lucas.

I know that clearing browser cookie regularly is a good practice, but I am a bit curious if clearing out those session cookies is the same as if you log out of all the accounts manually.

Because logging out manually will make both local and server side session cookies invalid, thus log out safely.

Meanwhile clearing browser cookies only delete local side session cookie, while the session cookie on the server remains. Which means the session is still valid.

So do I clear browser cookies or log out manually if I want to log out of all accounts?

Each time I perform a search in the search / URL bar in Firefox or on the Google.com website, the search results page scrolls to the bottom of the page automatically. I have no idea why. The issue does not occur in Chrome.

I am using Windows 10, Firefox version 89.0.2.

Basically, after I search, I have to scroll back up to the top of the Google search results page. Even after I have scrolled back up to the top of the page and clicked on the first link, once I go back to the Google search results page, the screen automatically scrolls to near the bottom of the page. It is extremely annoying, somebody please help. I can't find anything online about it. I don't think this is a scroll anchoring issue. SOMEBODY PLEASE HELP.

Firefox 89 on my Raspberry Pi 4 is displaying what I'm guessing is a codec issue. Videos can be watched but the picture is corrupted by brightly coloured patches around areas of detail.

Prior to the version 89 upgrade, version 88 was working perfectly.

I have Firefox 89 on a Raspberry Pi and a PC. On the PC it still works perfectly, on the Pi video is displayed badly.

On the Pi Firefox 89 is running under Ubuntu 21.04. On the PC Firefox 89 is running under Ubuntu 18.04

Am I alone in this or have others seen the same issue ?

Assuming I am not alone, does anybody have any idea what has gone wrong ?

Could someone please provide userChrome.css which puts the tabs back below the Address Bar in Firefox 89.0?

All the other solutions I've found end up putting the tabs at the bottom of the window where the status bar is. It becomes translucent and the + button cannot be found.

I had one userChrome.css which did put the tabs below; however, the whole top of the browser went to the bottom of the screen so the Menu Bar, Address Bar, and then the Tabs appeared below the page being viewed.

Has anyone found a version that keeps the status quo but just moves the tabs to where they should be?

Thanks.

The CSS element, below, is not rendered properly in the current version of FireFox for Windows. I first noticed it with the introduction of FF 89.0.

If a web page with this element is scaled, the image contained within the element does not scale. This element renders properly in other browsers (Edge, Chrome, Samsung, etc.), and the current Firefox for Android. There may be other CSS elements that use some component of this that also will not render properly, but I didn't test for them.


.pixHolder a { position: relative; display: block; background: transparent url(xxxxxx.gif) no-repeat 0 0; /* image does not scale */ border-style: hidden; height: 100px; /* size not relevant */ margin-left: 20px; z-index: 20; }

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

I want the home page to be blank when I open the browser, I want the home button to a URL. This was possible in older versions, and when you then updated the browser it maintained this difference - if it was already set. I did that once but I don't remember how far back on versions that is an option. Is it possible to do this in 89? If not, how far back should I go to install, make my home page and home button settings, then update to the current version. Then we're all good.

If you could supply a link to the correct FF file (windows 10, 64bit) that would be even more good.

thanks

When I open a website using special symbols, the symbols are replaced by a sign with 6 hex symbols in it.

It even happens when the symbol is used in the page title (see image). Site used: https://emojipedia.org/yawning-face/).

Interestingly, other emojis from the same site are displayed correctly (means the '01F971'-type symbol is replaced by the emoji, in all occurrences on the site and title)

I have seen multiple threads about this, even on this site. However, I could not solve it with the suggested solutions. What I have tried so far:

1. Disable addons 2. Make sure fonts are downloaded through settings 3. about:config -> gfx.downloadable_fonts.enabled -> make sure its true (4. no-script is not installed)


Any ideas?
