Firefox seems to partially freeze on my new MacMini M1 (2020) running MacOs Big Sur 11.1; I have the latest version of Firefox (84.0). It seems to happen when I log into my mac again after it's gone into sleep / screensaver mode. Firefox isn't completely unresponsive, I can still do some things, but for example: I can't enter text into the search-box, and other parts of Firefox seem unresponsive too (but it's nog 'completely' frozen. Closing and re-opening Firefox fixes it. Anyone else having this problem?

Firefox 84 - Problems with Gemalto Smart Card Reader and Crypto Module

Hi,

Since the FF 84 upgrade, FF crashes whenever I try to access certificates from a smart card reader. The smart card reader uses Gemalto classic client 7.3 security modules. The security device is loaded in FF and the installations has worked perfectly well with previous versions of FF (up to version 83). Since the upgrade however, FF repeatedly freezes and ultimately crashes when the smart card is present! If I unload the security device or of the smart card reader is not physically present, FF seems to work correctly.

Does anybody experience the same problems? Somebody has found a solution?

Many thanks in advance for your return. JBL

Location Services - Novel Latency Problem

Hello everyone,

Firefox 84.0 - fresh windows 10 format w/latest KB4592438

I experience intermittent packet loss and ping spikes upon authorization for Firefox to offer Location Services to websites like Hulu, BLS in-person skill courses, or shopping pages for stores like Target. I cannot recreate my network problems outside of this case and the issue persists long after I leave the involved webpages. Only closing Firefox restores my connectivity, while only Location Services is my only way of recreating the issue.

Thus, I open Hulu and experience high latency for however long until I close Firefox. But if I open Hulu followed by terminating the process and restoring my session, the network problem is resolved. What could possibly cause this? Why do I need to close and reopen firefox again and again to resolve connectivity problems?

I look forward to any recommendations. Please feel free ask for any further details.

It create an infinite digest loop with angularJS. Do you have any idea to fix these things? I use angularJS 1.5.8 and webix ui 5.0 Thank for your help.

Not much of an issue, but interesting. I have an iMac, 2010 that is running UBUNTU 20.04 as a development platform. Everything works pretty well (sound, WiFi, Monitor), but I get the error message above when running a certain application. The same application works OK when using Chrome, although not sure that Chrome is actually using WebGL

I tried tweaking a few settings in the browser and when I go to http://get.webgl.org I get the little spinning cube that suggests that my browser supports WebGL, but I still get that error message with the App. It might be related to the graphics drivers or my UBUNTU install, or the application software itself. Just kind of curious if there is a fix for that. I use the LINUX box mostly for development and I doubt there are a ton of people using FireFox on UBUNTU for web browsing, but not so sure about that.

One company that I support uses Firefox in Terminal Services on Windows Server 2019. For the most part it works great, no issues. But once every 10 days or so, everyone at the entire plant gets booted from their remote desktop session. They can reconnect ok, but it will only stay connected for about 5 seconds, then it disconnects again. This will repeat as many times as we try.

After some real-time troubleshooting, we have narrowed it down to Firefox. If I terminate all Firefox sessions on the server, the disconnects stop immediately and people can resume their work. Our next goal is to narrow it down to which website by closing users tabs one by one, but we have to wait for it to happen again and the entire company can't operate while we do this, so it is not an ideal troubleshooting method.

I am writing here just to see if anyone has any idea what might be causing this? We are kind of assuming it is either a rogue/malware ad trying to do its thing or possibly just a bug / memory leak in a regular website like Salesforce.

Has anyone seen similar behavior or have any ideas to try out? This has been ongoing for about 8 weeks. I was hoping a firefox update would fix it, but not yet.

I'm running an M1 MacBook Air with macos Big Sur (11.1), Firefox at version 84.0.1 (universal). Really happy so far, but probably 75% of the time, when I wake the machine from sleep, Firefox is frozen. I cannot click on any user interface elements or enter text. The only way out is to quit from the Dock.

I do run a fair number of extensions, so I suppose the issue might be with with an extension. Is there a way to find Firefox specific error messages?

If I click at that link on "Add an exclusion" and click also the next window to allow Firefox to be used, and don't say WIndows support always can access, Firefox opens endless instances with empty pages, until coming to 100% CPU load and 32 GB Ram limit load (I had to use taskmanager and closed Firefox)

E-bay and Woocommerce Problem printing shipping labels. Shipping labels print in both Edge and Chrome on both E-bay and Woocommerce site. E-bay's issue is it's printing blank labels. I can download the labels and then print. Woocommerece the page does not even come up to print. I tried removing popup blocker that didn't help. Amazon seems to printing shipping labels in Firefox with no issues. I have a Rollo thermal printer & using the latest versions of Firefox & Windows 10. So I do I fix this issue?

Win10 Bootcamp on new MacBook Pro with Radeon Pro 5600M. Device is powerful enough to run latest AAA games in high quality on 4K at 60 FPS.

New Edge plays videos like this in 4K at 30 FPS really well, but Firefox has very minor stuttering that is extremely annoying, as if it drops 1 frame out of 10, but "stats for nerds" don't show it. The videos just aren't as *smooth* as in Edge. It also has a big 1-2 second lag immediately after I change quality to 4K or unpause after switching tabs back, this doesn't exist on Edge.

Curiously, it plays 4K 60 FPS like this with much *less* lagging. I still notice a very minor stuttering compared to Edge, but not bad enough to be annoying, because it goes from 60 FPS to ~30 FPS at those times apparently.

Codec is VP9 in Edge and FF.

Tried:

- safe mode - same issue
- clean portable 86.0 Alpha 1 - same issue
- about:support is here, I don't see anything criminal
- performance profile using graphics preset is here: https://share.firefox.dev/3nMpss

I'm not sure where to dig here, since it's happening consistently even on latest nightly build and the symptoms are this weird.

Pandora is slow to load and when it does a yellow banner shows saying "A website is slowing your browser" This problem started a couple of months ago, all worked flawlessly until this. Please make it stop! Thank you ~ also, it does not make a difference if I have another website open. I tested it; same result. The Yellow Banner.

I have one PC that uses Firefox by default where Windows is attributing 460 GB/month of data usage to Firefox! Have verified via a network monitor that indeed that PC is using over 500 GB of data per month.

Not using Firefox for streaming or gaming - just looking at web pages.

What could be causing this huge data usage? How might I bore into this at a Firefox level?

Thanks, Bob
