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 ?

My tab bar and menu bar background is white. I have the latest FF version and I hear it should be black but it isn't. It used to be but I may have changed something and lost it?

How do I make it black for ease of visibility - but not the web pages (just the upper bars). I have searched for hours and none of the answers either match what to do, or work.

Dear Community, after one of recent Firefox updates I experience an issue with text display on certain pages. Some text is not visible because it is white on white background. The text is there, I can highlight it. I am using latest Firefox release as suggested by auto update. This white on white issue is regardless of selected Theme, even in dark theme it is white on white. Please have a look at the attached screenshots.

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

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'm finding that Twitter is not loading in my desktop Firefox browser (89.0.1), and I'm getting the error "failedScript=polyfills". I do use an ad blocker, but it's turned off for Twitter, so I'm not sure how that could be the issue. I'm not having the same issue in Safari. Thanks for any help!

So I have been using a theme for Firefox for some time now, years, called Abstract Electric, makes the tool bar dark with a nice little streak of lightning or something. The tabs are dark but the drop down menus used to be white with black writing. Now this morning there was an update to Firefox and everything stayed the same except the drop down menus are now black with white writing. Can't figure out how to keep my theme which I like but put the drop down menus back to white with dark writing. I only want to change the drop down menus, not the color of the tabs or anything else, just want to put the drop down menus back to black on white

The floating tabs are awful. They all mix together and look like one giant tab which makes it infinitely harder to find what I'm doing when I have many tabs open. The proton design is disappointing all around but these tabs are unacceptable.

I've searched this topic since last week and I haven't come up with a proper solution. The "density" solution is still too big for me. I tried doing css, but I don't know what I'm doing wrong because there's no effect.

If you know anything how to make the tab bar thinner to make it less intrusive to the websites I always visit, please let me know. And btw, I'm not that smart in changing settings, and especially in coding like css so please do a step by step of everything I need to do if you know a solution. Thank you so much

I used to use a lot the three dots next to a webpage to share the page via airdrop (to have it/share it with my own phone or others'). Now the three dots have disappeared and, although I read here that I could do that by right clicking the page, the option for SHARE does not appear. Can you please explain how to do this now? (I use a Mac).

When I now open my firefox browser it will only open in a minimized window located in the upper left corner of my monitor. I then need to click the "minimize window to change to "maximize" and then click it to open the window to a full size screen. As I open new tabs after this they open in full size screen mode. But once I close the browser I have to start all over again. Is this happening because of the new update? Would appreciate your help please. Note: I did not take a full pic of my desktop, just the top portion that includes what I see when I open the browser.

Ok so it's been a long time that i left chrome and joined the firefox community but there was always something which felt left out, so i downloaded chrome again and found what that was. It was the size of toolbar.. In chrome toolbar is smaller but in firefox it takes some space. So i want smaller toolbar here in firefox because i love every other thing here. So is there any way to do this? Thanks,.

Hello, until yesterday, I had the video downloader helper icon on the right hand side of my top list of sites near my Firefox account icon. Now in the 89.02 version, it's gone so I can't download directly movie trailers for example. How do I put that icon back on around there? Thanks Luc

After a crash, or even after shutting down the computer without closing all Firefox windows, Firefox will restore all the windows and tabs from the last session on restarting Firefox.

There can be many reasons why this may not be preferred behaviour for many users: Sometimes Firefox or the computer crashes because too many windows and tabs are open (and other applications running), killing Firefox may be a measure against malicious pages trying to hijack the browser, discarded pages after shutdown do not need to be restored, ...

So is there a way to make Firefox immediately ask whether to restore the session, like it already does after the second crash? This should actually be an option in the settings.

I cannot access to Facebook or Messenger on Firefox, when i open, Firefox said Secure Connection Failed. I got this error for a week,i have used Edge and Facebook still work,pls help me.
