Firefox Support Forum

Video on some websites is choppy after updating to a newer version of Firefox (115.8.0esr). I have attempted to upload a video of the problem but it seems only still images are allowed and this doesn't illustrate the problem. An example website where this occurs is https://www.fiat.it but there are plenty of other examples. It looks as if the playback is jumping forwards and backwards between frames. Strangely Youtube videos seem OK.

Some information which may be of use

OS: OpenSuse Leap 15.5 HW: Dell Precision 7510 with Nvidia Quadro M2000M video card and driver version 550.54.14

I have also noticed that when starting Firefox from the command line I see frequent messages like

Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index3/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/present Sandbox: attempt to open unexpected file /sys/devices/system/cpu Sandbox: unexpected multiple open of file /proc/cpuinfo

Probably not relevant but I included it just in case it is useful

Any help you can offer with debugging would be much appreciated, thanks

The video from most websites plays out of sequence. It appears that approximately every one second plays its frames in reverse order. This occurs with most video streaming services and major sites. For example, all Amazon, Sam's Club, Walmart and other website product videos. Occasionally, Amazon product videos just say not compatible. However, YouTube videos with very rare excepts play fine in Firefox. Those problem sites play the videos fine under Edge for Linux. But, I would much rather use Firefox. I'm sure this a codec related issue. Possibly related to the NVIDIA GeForce GT 1030 video card in this computer running openSUSE 15.5. But after much searching, I'm at a loss on how to resolve the problem.

Hi all, due to the occurring problem I cannot select topic to describe best my type of question:

Description of fault: Using Open Suse Leap current version 15.3 (KDE) with all patches installed (zypper dup: no action required) In either thunderbird and firefox application (but e.g. not in dolphin or k3b or gimp...) I have following problem: When pressing any entry in File ... View... bar I do not get a visible dropdown menu to chose from Firefox specific: When I try to use a bookmark folder in the bookmark bar there is no visible dropdown menu to chose from When I try to chose from a dropdown menu inside the content of a web site i will get no visible feedback at all.

BUT: when I want to chose a bookmark that should appear in a dropdown list and I move the mouse to that remembered position I see in the lower left corner the bookmark's address and I can chose it! The same happens with the dropdown menus from the the File.... View... Help line. I am able to chose a command once I remember where to point to.

So I guess all what is missing is the overlay plane where the menu contents reside.

This problem occurs in 95% of the time I use both applications, BUT there are 5% of the time where everything works like a charm. I have no idea what i do differently in that usage. Whenever Firefox works normal, also thunderbird does. Is it somehow a KDE releated problem?

How can I fix that problem? Any hints?

Thank you

Johannes

For the last few months YouTube appears to have broken CSS and text in multi-line blocks is broken and overlaps. I'd guess this is only for text that auto line wraps. The example screenshot is of a pseudo dialog but the problem is everywhere on multi-line text in YouTube.
