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 have two FF profiles. When I open a private window in each profile and go to YouTube, one displays YT in light mode, while the other displays it in dark mode. In both windows, YT is set to ‘Appearance: Device theme’. Both profiles use FF’s ‘Dark’ theme. The same happens when I go to other websites that utilise ’ prefers-color-scheme’ (e.g. https://dashboard.tugboat.qa).

Since these two profiles display websites in different colour schemes on the same computer, it’s clearly not an OS setting. It therefore must be a setting in FF - one that’s enabled in one profile but disabled in the other. I’d like to know what it is.

I’ve tried comparing about:config in both profiles, searching for things like ‘dark’, ‘theme’, ‘color’, etc. But I can find no differences. Can anyone shed some light (pun intended) on this for me?

Got a new computer running latest version of Firefox 89.0.2 64 bit.

Tried YouTube and CNN, when I open a video there's audio. When I scrub (move to another time on the video) to another timestamp, the audio is gone. Dailymotion has no audio at all. I tried Spotify Player, there's audio when I play the song but if I try to scrub, playback itself fails. Chrome works perfectly fine and my old computer with the same version and setup has no trouble at all. Please help!

Running Windows 10 64 bit with the latest updates on Firefox of 89.0.2. I cannot open a new tab to the google search bar by just opening a new tab. It defaults to showing a google search bar, but Firefox will not allow me to type into it. I am constantly redirected to the address bar to write my google searches or to a separate "search" in the same address bar, depending on which option I selected in settings.

I only have two options in Settings: 1) Use the address bar for search and navigation or 2) Add search bar in toolbar. I have Google set as my search engine.

Your previous version of Firefox did allow me to do exactly what I wanted. Now I cannot.

Under "New Tab" you only allow for 2 selections; Firefox home or a blank page, the latter of which does not show the personalized "rows". If you allowed a Google option there, it might resolve my problem.

I attached a picture of my new tab; it shows the search bar for Google, but it now says "Firefox" where it use to have the ever changing "Google" Logo. I do not mind the Firefox logo, but I seriously am upset that I am forced to type searches in the address bar. Who does that?

Furthermore, by forcing me to type in the address bar, its much harder to see what I am typing and allow for me to make corrections. Once I hit enter, it sends me to a typical Google search page, where I can then make changes, but this seems like an annoying step.

Am I missing something, some setting someplace where I can type in the search bar I indicated on my attachment?

On a side note: Thank you for adding a "Personalize" button on a new tab. It now allows me to add rows for shortcuts. Before I had to:

1. Load about:config?filter=browser.newtabpage.activity-stream.topSitesRows in the Firefox address bar. 2. Double-click on the preference browser.newtabpage.activity-stream.topSitesRows and change its value to the desired number of rows and click ok. 3. Check the New Tab Page to see the change right away and modify the number of rows accordingly if needed.

Which I technically have yet to change, because I prefer more than the 4 row limit you set. You will see those shortcuts in the attachment for the new tab.

Thank you for your time. Be safe and have a good day. :)

I've used Firefox as my primary browser for many years. Recently (few days) when I watch videos on Youtube, the video will stall with a circling loading icon for 20-30 seconds. After this the video will resume play but without any sound. Opening a new tab will play videos without problem for a while before they, too, exhibit the symptom. Neither Chrome nor Edge exhibit this symptom.

I have a clean install of Firefox with no extensions.

Things I have tried: I've disabled hardware acceleration. This didn't fix the issue. I have played videos in safe mode. This didn't fix the issue.

Any thoughts?

There are many instances where I click on submit, and a new tab appears with the heading javascript_... Normally I can go back to the previous tab and continue. At times however it looks as if the javascript was never executed. In this case I'm logged into Merrill Lynch and attempting to select an account. I select the account, click submit and a new tab appears with the javascript title. The URL is javascript:__doPostBack('ctl00$ctl00$ctl01$cphSiteMst$cphNestedPage$cphStage$ctl00$Submit',). I go back to the original page and nothings changed. Other browsers work. Yes, javascript is enabled. I do have some add-ons but none which disable javascript. Any thoughts? regards, Bob

The fact that this new version always puts focus in the URL field is bad enough, but it now refuses to use the web search field for any searches. My Search settings are set to "Add search bar in toolbar" and Home settings are set to show the "Web Search" field. In about:config, keyword.enabled is set to false.

Everything typed into the Web Search field goes directly to the URL, but since using the URL for searching is turned off, a search there will always fail.

This is a new "feature" that arrived with the latest update.

Any ideas how to fix this would be much appreciated. I want to search from the Web Search field and do not want the URL to be used for anything but resolving actual URLs.

Thanks in advance.

WIN 7 FIREFOX HAD A "VIEW" BUTTON IN A TOOLBAR AT THE TOP. I USED THAT BUTTON TO SELECT VIEWING ALL MY BOOKMARKS IN FOLDERS IN A COLUMN AT THE LEFT SIDE OF THE SCREEN. THIS IS CRITICAL FOR MY WORK BUT I HAVEN'T FOUND ANY WAY TO DO IT, NOR COULD I FIND AN ARTICLE DEALING WITH EITHER OF THESE BOOKMARKS ISSUES.

I am an older Firefox user and I often find myself enlarging and decreasing size of fonts on different websites to make them readable. Lately I notice I am having trouble with the fonts I am using so I need advice. What are the good fonts to use for Firefox? Also, what is the setting to adjust the fonts Firefox uses in the toolbars and address bar?

I am currently using as follows: Default: MIcrosoft Sans Serif (I like the clean lines of a sans serif, but I'm not wedded to any particular one. ) Size: 10 Proportional: Sans Serif Serif: Newsreader Sans Serif: MIcrosoft Sans Serif Monospace: Lucida Sans Font size: 10 Minimum size: 9

The problem I am having is that text in the address bar is often unreadable due to artifacts that look like a digital font, you know, the blocks? If I highlight the URL inside, the artifacts clear up. I reinstalled Firefox but that problem didn't go away. I need to know which font Firefox uses for that area before I can even begin to try to fix it. Any font suggestions are also welcome. I particularly would like fonts that are readable in many sizes and free of flourishes.

By the way, I chose the image of Google News because I also have trouble with alt text showing, I can't figure out how to get rid of that so any ideas are welcome. It's just Google.
