Hello. I often use a frame interpolation application called Lossless scaling (LS) for watching YouTube videos. LS captures frames from a window using APIs like DXGI or WGC and generates interpolated frames between them. When running LS with YouTube videos played in full-screen on other browsers, it correctly detects and operates at the video's native framerate. However, when using Firefox, the application detects a framerate 2 to 3 fps higher than the actual video fps. For instance, a 60 FPS video is detected as 62 FPS, resulting in poor frame pacing and a noticeably choppy playback. It works fine in Chrome or Edge, but I would really like to resolve this issue.

FF sometimes doesn't open links from email, and sometimes other links in a site. Frustrating when I need that download but can't get it. I disabled all my extensions, closed and reopened FF, but it didn't change anything. Had this problem with Brave too and it got so bad it was inopperable and had to delete it. I'm using Google for DNS.

Any help is appreciated

Have been "printing" web pages to PDF for ages. All of a sudden one site creates a PDF output with 0-bytes. i.e. it's empty. Other sites I use still work normally.

Firefox 134.0.2 (64-bit) on iMac

sometimes when I open a new tab and type in a new url and hit enter the new tab will close. Also if I right click on a link to open a new tab, sometimes that new tab will open, and immediately close. What can I do to stop this?

I am running Windows 11 and the latest version of Firefox. Firefox was working perfectly yesterday, but today when I tried to open it, I got the message "This app can't run on your PC". What could be the problem and how do I fix it?

Thanks,

David

I have a development copy of my website that I run directly from my local disk. I have indexes with links to pages that I load in frames. When the target is another frame, the link will not work. This stopped working when I did the last update to Version 134.0.1 The links work when I load my online version from HostGator.

By using Process Explorer or Process Hacker or maybe task manager, I hope you can also verify that Firefox consumes a few GDI handles per open tab. Windows has a global limit and a per process limit of 10000. GDI objects are used for windows, for the file save dialog and also for user interface elements like buttons or lists. However many applications like Firefox draw everything themself like XUL etc. But still, Firefox consumes 3 handles for me (verified on another computer) per open tab.

If you have a lot of tabs open (for reasons not to be discussed in this topic) this can be problematic. If it reaches 10000 windows will not create more. Sometimes firefox hangs, but often Fullscreen (e.g. youtube videos) will not work and the gui will disappear. Also the context menu will not open and the save dialog cannot work and is hidden.

Am I the first to report this? I did not find anything. Can this be fixed? Can I post this to bugzilla?

Can anyone confirm this? The latest version does not fix it.

Hello,

I am experiencing discoloration on the top left corner of my firefox browser theme when I am in "full screen view". The discoloration disappears when I exit from full screen mode to "window view". This discoloration is happening on every theme I enable. I have attached two pictures to show what I am seeing between the full screen view and window view.

I am running Windows 11 and have a 32" curved monitor. I searched for solutions such as disabling hardware acceleration, but nothing seems to be working.

Any help would be really appreciated!

Thank you!

There is a bug in Firefox Browser where it doesn't allow you to scroll up in the chat during the livestream and keep your place there to read a message. It auto scrolls down to the new messages everytime a new message appears in the chat.

Firefox is the ONLY browser that does this so it must be a bug. Chrome, Edge, Opera, Brave, etc none of these do this. It is especially problematic in livestreams with many viewers and an active chat, making it impossible to read a previous message if you want.

It happens on all platforms, twitch, kick, YouTube, Parti, Rumble, anything with a live chat
