Firefox Community Forum

Greetings,

Following a recent Ubuntu update from 20.04 to 22.04, Firefox 129.0.2 has started spamming my syslog with messages like:

[Parent 39719, IPC I/O Parent] WARNING: process 262891 is a zombie: file /builds/worker/checkouts/gecko/ipc/chromium/src/base/process_util_posix.cc:245

These seem harmless, but I'd like to identify a way to suppress the warnings, because they're mucking up my syslog. Is there a setting in about:config that would do that? I see lots of log-related settings there set to Warn, but have no idea which one could silence the warnings I'm seeing. Any tips or suggestions are much appreciated!

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

I need to uninsntall my present version of firefox and reinstall an upgraded version . i have a desktop frontier has ended their e-mail and therefore I no longer have the e-mail that everyone knows me by I have no e-mail except on my phone. My reachaable E-Mail is marcumgrover@gmail.com

I have used firefox for quiet many years now, but recently after the update, it i sucking in a lot of resources, I am not sure what the problem is but the cpu engagement of all the 4 cores are getting to 50 percent and longer uses are making it go as high as 95 percent. So, I have already done the following,

• Previously I thought it to be snap issue, so I changed to deb but that also didn't changed much.
• Then I thought it to be some other issue and tried to fix few log issues of ubuntu which I think were unrelated to the problem.
• The system is running so hot that one can't put his hand on it for long.
• Ultimately I switched to fedora, and everything came to normal. The firefox then was of version 123 or 125(or 126, but it was 2-3 versions back, you may find it with what version fedora ships with but I remember it to be significantly lesser than 129).
• I use 3-4 windows at a time with 6-10 tabs open(but mostly pdfs). The firefox was working all fine with no temperature and resource issues, then I remembered to do update, and soon as firefox is upgraded to 129. It has started to cause the same issue, it is damaging the hardware, the hissing sound and temperature increase have come back.

The outcome is that I have came to know that there is some problem in either the upgrade process or the new version. THIS IS HIGHLY DISAPPOINTING. Please provided instructions on how to fix it, or should I open a issue in bugzilla, I can not understand what is the problem? please ask for an other information if required.

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

I mistakenly dragged a text from a search box and dropped it on my browser page. If this text is a url (Ex: www.some_site.com), Firefox will navigate to that page. How do I prevent Firefox from opening dropped links on pages?

For languages that don't put spaces between words there's a Unicode character zero-width space - ​ aka ​ - that a browser is supposed to use as a cue to break a line. Firefox ignores it.
