Hi,

I have scoured the web and can't seem to find a solution to this. Either firefox doesn't support this feature or I haven't looked enough.

How can you identify the pid of a tab in firefox? There isn't a tab in the task manager that shows this, like with chrome, opera, and edge.

I'd appreciate any help.

Thanks

This is suddenly happening to me on Firefox 92.0 (64-bit) running on Windows 10 21H1. Worked on 9/12, failed consistently starting 9/13, (possibly coinciding with auto-update from FF 91.0.2 to FF 92.0). I'm using WidevineCDM version 4.10.2209.1 to watch Xfinity stream recordings. Have submitted 3 crash reports via FF.

I'm finding that Twitter is not loading in my desktop Firefox browser (89.0.1), and I'm getting the error "failedScript=polyfills". I do use an ad blocker, but it's turned off for Twitter, so I'm not sure how that could be the issue. I'm not having the same issue in Safari. Thanks for any help!

Hi,

Since I installed Firefox 89 (Windows 10 and 8.1), Firefox keeps losing the connection to Internet. I have to close the browser and re-open it to be connected again. When the connection is lost, I can go to another browser and it works fine, the issue is only with Firefox. Any idea?

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

I also tried h264ify as I read about the video codec youtube uses but that didn't fixed it and also tried a solution on the forum that said to disable H264 plugin and enable h264ify but that didn't worked as well

Hi all After update 90.0.2 installed on my computer, FIrefox started flickering all the time a new page gets opened. I have never had such a problem before, nor I had any hardware change in the last two months. I tried several proposed solutions concerning flickering like refreshing, disabling hardware acceleration etc. but nothing helps. I wonder what happened in 90.0.2 which caused that. I just installed update 91.0 and the flickering still persists.

I am using Windows 7 Enterprise 64-bit on a Dell Vostro 3750 Laptop if that matters. Thank you

I was directed here from Mozilla Connect. Since the update a few days ago, my Firefox browser keeps freezing permanently. It seems to happen mostly when I interact with Google Search (sometimes just loading Google will cause it) but it does happen occasionally on other sites. When it freezes this way, the only fix is to End Task and reload. It will successfully reload to the state it was in just a few seconds before freezing. I'm on Windows 10. I keep everything (OS, browsers, etc.) up to date, so I doubt that would be a factor. I wonder if there could there be an issue with a Google-based script (hence it occurring on other sites)? I don't know how I'd test for that.

On some websites the fonts are all displaying in a large bold text instead of whatever font that page is meant to use. It will revert to a default font if i turn off the ability for sites to choose their own fonts, but this interferes with the functionality of a lot of sites' icons so its not a great solution. This also stops when i go into troubleshooting mode, but when i went through hardware acceleration and my extensions one by one, none of them were the cause.

images in order: my roll20 homepage with the incorrect font display, the same page with fonts disabled (note the notification icons in the upper right are broken now though), the same page in troubleshoot mode with the correct font display

Ever since I started using Firefox which was months ago, I've been getting this "Hmm. We're having trouble finding that site" page multiple times a day when opening links to various websites. Refreshing the page makes it load correctly. I've tried troubleshooting this in the past but didn't spend too much effort, but enough is enough. Things I have tried:

  • Disabling all extensions
  • Disabling hardware acceleration
  • I am using the default theme so there's nothing to disable there
  • Clearing the cache
  • Checking my internet connection (I'm connected and everything else works)
  • Flushing my DNS
  • Resetting Windows, which included reinstalling Firefox (I did this to fix something else, but still)
  • Disabling IPv6 and DNS prefetching
  • I am not using a Proxy

I feel like I've tried everything. What else can I do?

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

Firefox RAM usage on M1 Mac has dramatically increased. Unfortunately, b/c the memory usage is in firefox parent process, I can't simply terminate a process corresponding to a "tab", meaning I have no choice but to restart Firefox (closing & reopening all tabs) every hour or so of usage.

This is a new issue from a long-time firefox user (on multiple operating systems). It happened after I upgraded the Mac to "Monterey", which may or may not be coincidence.
