So for example, I have https://open.spotify.com/collection/tracks bookmarked. Pretty much every time I want to open that link, whether from top sites in a new tab or if I search that bookmark from the URL and click it, nothing happens. It will, however, work the second time I click it. It seems like really odd behavior.

JIT/GC/Cycle Collection hanging periodically

After my browser being open for a while, usually a few hours, Firefox starts to get some major hanging in some tabs; I can have two windows open, one with a youtube video playing and another with like reddit or something else, and when browsing reddit, I get major hanging when interacting for around 7 seconds.

I recorded a couple performance profiles to see what's causing it, and it seems to consistently be a very long JIT or GC call, also labelled as "Cycle Collection" in the waterfall view.

I saved the profiles and I can upload them, but I'm not sure if they come with any private info so I'm reticent to add it to this thread.

I've watched the Task Manager (the Firefox one and the Windows one) while this is happening and memory usage in the Windows task manager seems to rise quickly over a few seconds then suddenly drop back down. I'm not sure if that's relevant. In the Firefox Task Manager I didn't see anything particularly salient other than energy usage spiking up just after the hanging is over.

This doesn't only seem to happen on Windows because it also happens on my Linux laptop occasionally as well, in a very similar manner. I didn't collect any evidence on Linux yet.

This has been happening for quite a while now, on multiple versions of Firefox in a row. I'm using 79.0b3 Developer Edition right now on my Windows machine.

Closing and reopening Firefox usually causes things to clear themselves out and I don't get such long hanging for a while.

I would expect JIT and GC to happen in much smaller chunks to avoid hanging, it's strange that it takes that long for one call.

Two degrees of full screen mode

Using 78.0.1 on Windows 10, when I press F11 to get full screen in Youtube TV, it works, but it leaves a thin grey line at the very top of my screen (1280x800 resolution showing 1280/720 YTTV), and mousing over it drops down the Firefox tab and URL bars. That's "Full Screen Level 1". Using --kiosk prevents the dropdowns, but it doesn't get rid of the line.

If I play some video and mouse over the Firefox window while it's in Level 1 and not displaying any UI, a full screen icon appears in the upper right. Clicking it gets rid of the gray line and briefly shows the message, "youtube.com is now full screen." Now, mousing over the top middle of the screen displays that message instead of the Firefox UI. That's "Full Screen Level 2."

When I start Firefox, it remembers Level 1, but not Level 2, and the only way I see to get Level 2 is to click on the icon. I want Level 2 all the time for this profile, which I use on a small secondary monitor, and only for YTTV.

Any ideas?

Please look at the attachment, the last two titles just can't fully displayed as they are too long. But even I edit the title to make it as short as possible and recognizable, they are still not short enough to be shown fully. How to set it? I want to let them fully displayed no matter the length. Thanks

Fingers crossed - I may have solved this problem by completely uninstalling and reinstalling Firefox. The problem: Every time I opened Firefox, the Safe Access app on my Synology RT2600ac router would send an alert to say that it had blocked a connection to vice.com. I've never visted that website, so I have no idea why Firefox would keep triggering an alert from my router. Has anyone any idea what might have cause this?

My Firefox Browser deleted itself somehow and microsoft edge took over as the default browser. I clicked on the browser in my task bar and a grey error box came up and said the short cut needed to be removed because foxfire.exe was not found. Then on my desktop I had a new folder called "Old Firefox Data".

I had a issue yesterday where I downloaded 2 Viruses (in a zipped folder) off the firefox secure transfer app because I thought it was a contract for work. My virus scan software removed the 2 trojan viruses and corrected the unauthorized changes to my computer.

How did the entire Firefox.exe disappear? Do I still have a problem? Thanks in advance!
