Om Macos 12.7.3 Monterey using FF 115.7.0esr (64-bit). Been using FF since God knows when. All well. But a couple of months ago windows or tabs are crashing. When I'm hitting a link and either holding Cmnd or right click "open in new tab" in order to get the linked page in new tab, the tab/window I'm using shuts down. Poof.

For the longest time (can't pinpoint when it started) I've been having issues with Firefox on desktop (Macbook) playing videos and occasionally audio. Video playback will be functioning fine, then there seems to be a "trigger"...For ex. I have noticed this is often me trying to play a Twitter video, which won't play normally, and suddenly NO video playback of any kind (and sometimes audio) will work...Youtube, Netflix, you name it.

The only thing that "fixes" the issue (until it pops up again the next time) is quitting Firefox and starting it back up again, usually clearing my cache first for good measure. I have tried disabling all extensions and it has no effect. I have tried playing the video in a private window/incognito—no effect. If I open up Chrome and try to play the same videos I have absolutely no issues.

My Firefox says it is currently up to date, though I am running an older version iOS (Mojave). I have googled and seen many other people having this issue but haven't seen anyone chime in with a fix that actually works. Any ideas?

Hello,

Firefox YouTube HDR mode works in Full Screen Mode (FSM), Picture in Picture (PiP), but not in normal Windowed mode (WiM). This bug appeared in around Q3-Q4 2023, before that the YouTube HDR mode was available in FSM, PiP and WiM mode.

In Safari the YouTube HDR content works in FSM, PiP and WiM mode.

Firefox 115.7.0esr (64-bit) macOS Sonoma 14.3 ( I updated the system from macOS 13 in the last 2 weeks ) MacBook Pro 14", 2021 w/ Apple M1 Pro (1000 nits sustained full screen, 1600 nits peak)

This issue exists in all HDR videos what I tested on YouTube.

Hello,

In Windows 10 and 11, Firefox's tab bar and other elements that may be transparent render in Windows 10 using some sort of uDWM method (speculation, I could be wrong?) rather than the traditional win32 window frame as you can see with the title bar toggled on. This leads to elements like the tab bar being black or white, depending on your theme unless you have specified otherwise in your chrome. Highlighted yellow below is my problem area.

In my CSS code, I am trying to extend the system color to be drawn to the tab bar (and in this instance, the address bar as well,) but I can't find any way to be able to do this. I have found forums that say to add -moz:appearance -moz-windows-glass, but this completely removes the window border and leaves the Firefox window unresponsive to controls. The only way to close it is if you close it through the taskbar or task manager.

Note that I am aware of .titlebar-color{color: AccentColorText; background-color: AccentColor}, but that's not what I am going for here. That still draws using Windows 10 modern UI. Windows 7 on ESR 115 or unofficially on 116 still draw with Windows Aero in all parts of this CSS code that are black (highligted yellow below.)

I can attach my CSS code if need be.

Thanks for any help!
