Firefox supportforum

Firefox was working like a charm on my MacBook Pro '16 19 with Venture 13.0 macOS, without any issues. But somehow, after I did upgrade to Venture 13.2.1, Firefox started random hangs/freezes after each 30-60sec. And it takes ~5-10sec. I started to get random panics 2-3 per day.

I did not changed anything in the settings. This also happens in Private Window mode. I usually restart the computer everyday. (Eventually a new Firefox instance each new day, before Ventura 13.0 and still do after upgrade)

I have read the followings:

• https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
• https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

But didn't help me. I have everything (tabs, favs, extensions, works, etc.) so that I do NOT want to reset/refresh ANYthing. I'd prefer to fix the root cause and understand the issue why it keeps occur.

I either change my main Firefox browser (after 8+ years) or look for a solution to fix the root cause without doing any refresh or reset (or something that cause data lost).

Is this a known issue?

Could you please help me on this? Thanks!

My Environment:

• Firefox 110.0
• macOS 13.2.1

Also, in the Troubleshooting Information section below, browser somehow couldn't collect to data and showed a "manual way documentation" button. I clicked it and it redirected me a doc. When I back to previous page, I lost the data I've just written here. So had to rewrite everything... Can you please fix this?

I found that when starting Firefox on my school's WiFi, it starts up very slowly. Using `strace`, I found that it was taking it's sweet time making a DNS request to try to resolve my computer's `/etc/hostname`. After searching the Firefox source code with https://searchfox.org/mozilla-central/source/, I found that the only occurrence of `/etc/hostname` was in [SandboxTestingChildTests.h](https://searchfox.org/mozilla-central/source/security/sandbox/common/test/SandboxTestingChildTests.h). So I was wondering if it's possible to disable these tests when Firefox starts up.

Ref Firefox Ver 84.0.1 OS > Win 7-64 Dear Firefox Support,

 I have already contacted MS support about the subject issue and they were no help.

I am trying to find out what is causing the issue and how to get rid of it.

 I can't be sure but it may be caused by a Microsoft "START" App.  The issue appeared

to begin about two weeks ago, so it's obviously caused by something new, which may be Microsoft related. Below is Dropbox link to a screen capture of the issue.

 Any tips for ridding my PC / Firefox browser of the issue will be greatly appreciated.
 And thank you for the superb browser.

Best regards, Ken Boardman > elsmoko@cox.net

i installed the latest version from the website, and it only opens for a split second before it crashes. no error message, it just closes before its even fully open. same thing in troubleshoot mode: the troubleshoot mode popup only appears for a second, i dont even have time to read it before it closes. no error message. i tried a clean reinstall and nothing changed. i opened it in safe mode and it worked with no problems. i read that there are sometimes issues with avast, which i used to have, so i deleted the residual files i found in AppData and Program Files. still nothing. now the only antivirus/firewall software i have is windows defender (and i know that because windows defender keeps telling me haha), and i tried adjusting the windows firewall- still nothing. i would love to include a crash report ID, but there are no crash reports in the folder (photo attached), even though ive tried to open the app half a dozen times since reinstalling.

not sure if its relevant, but just in case- when i couldnt open the version from the website, i tried installing it from the microsoft store, and it actually worked fine at first. but shortly after i finished setting it up (it was probably open for less than an hour), it crashed and then it was the same- crashing immediately upon startup. i have since uninstalled it, in case they were interacting in a weird way, so now i only have the version from the website. i also have the mobile app on my phone and it works like a charm.

i consider myself pretty good at troubleshooting, but im completely stumped here. sorry for the long post, any guidance would be greatly appreciated

When I try to open "www.metservice.com" Firefox freezes completely. This did not use to happen and does not on Chrome. I have to restart my laptop to fix the freeze!! As it is a site I use regularly it is somewhat of a nuisance.

I tried using troubleshoot mode and the crashes happened on there too. I uninstalled and reinstalled firefox, created a new account, removed and added my extensions back on, restarted my computer, and yet the issue keeps persisting. The browser doesn't prompt me to send in a crash report when this happens either, it's only the tabs not the browser itself that repeatedly crashes.

Since the last update various programs we try to play on ITVX.com hang Firefox. Again tonight we ended up having to switch to chrome which behaves ok. End up having to crash FF from Task Manager.

Windows11 Firefox 111.0.1 (64 bit) intermittently stops loading page while scrolling. Won't refresh or go back to previous page. No error message. Have to restart Firefox.

Youtube has this issue the most. On any other browser YouTube works fine; however, on firefox, videos sutter, play at a very low FPS and if I try to interact with the page like pause the video, it takes somewhere between 5 to 20 seconds for the site to respond and actually pause the video.

This happens on other websites as well that have interactive features

Additionally, when on sites like discord or LinkedIn, if a video starts playing and I pause it the audio will continue playing and loop and overlap over itself. The only way it will stop is if I refresh the site.

I have tried updating my video drivers, reinstalling them, changing all the settings possible on my computer to make it work but nothing yet. Thanks for the help.

In the last 4 days Firefox is constantly freezing on the Tile Pages of multiple streaming sites. It becomes non-responsive, and won't let me reload or use the Home button. I have tried turning off hardware acceleration and clearing the cache and I still have the same issue.

When DNS over HTTPS is not enabled in Firefox and I set network.dnsCacheExpiration to 600 seconds, evidence from about:networking#dns shows that the minimum DNS cache expiration time is indeed 600 seconds. However, when I enable DNS over HTTPS and set network.dnsCacheExpiration to 600 seconds, the network.dnsCacheExpiration setting seems to be ignored. New DNS cache entries are able to have far less than 600 seconds to expiry. Why is network.dnsCacheExpiration ignored when DNS over HTTPS is enabled? Could this be a bug in Firefox?

I am using Firefox on Ubuntu 18.04 (current release 111.0, but the problem has occured over the last two releases). I like to open the individual page from a Youtube playlist so that if I get distracted, I won't lose my place. I do this either when disconnected from the internet or using the "work offline" feature. Previously firefox would show either "Problem loading page" or "Serve not found," but now it keeps trying to load youtube which sucks up time, cpu, and memory.

These are pages that I have never been to before so there should be no record in history, but even so I have tried clearing my history and this did not help. I have tried a bunch of other sites, but Youtube is the only site that I have seen this behavior on. Attached is an example (The google page and the first youtube tab were loaded online). The shown youtube tab (second tab) and a random webpage from google (last tab) show this behavior.

Could you please help me.

Ever since the update Firefox has been taking at least 10-15 minutes to load. The when it does finally load, I can't always get a webpage to load...at least not for another 10 minutes.

I restarted the computer, cleared the cache and cookies, disabled all extensions...nothing helped. This happened the last time Firefox updated. At the time I just stopped System Mechanic from interfering and it worked easily again. This time it isn't System Mechanic, it doesn't seem to be the extensions....what now?

None of my bookmark functionality is working. I have restarted Firefox and cleaned out all extensions etc and so doing have discovered it's only when I reinstall Last Pass that the functionality stops.

Is there any known fix for this, or can I simply no longer use both Firefox and Last Pass together?

Thanks

Hi, using firefox for a long time. 2-3 days ago FF started to start slow. If I open FF, it shows me FF GUI without any icons and after 3-5 seconds it starts completely.

Tried to disable all extensions (bitwarden, ublock, easy screenshot, feedbro), same result. Tried to clear cache, cookies, history - same result. At the end I made a reset of firefox via menu, same result. FF is latest version.

See screenshot - this is what I see after start firefox (for about 3-5 seconds) Any idea / fix please?
