Firefox 技術支援討論區

The page I was on randomly crashed earlier today, and now every time I try to open another webpage, it crashes within 1-5 seconds of when I try to open it. I have tried restarting Firefox and running it in troubleshooting mode, neither of which helped. My Firefox version is up-to-date, and I have never had this issue before; I'm also not getting the "crash reporter" dialogue so I don't have access to information about the crashes, even through the Finder library. I'm not sure what's going on?

Hola, tengo un problema, Firefox ha dejado de cargar, da este mensaje "Couldn’t load XPCOM" he intentado hacer otro perfil, he borrado las carpetas he reinstalado... pero sigue dando el error. gracias.

Solucionado viendo un video en Youtube:, por alguna extraña razón, simplemente cambiando el nombre de Firefox.exe por firefox1.exe, carga y funciona a la perfección

Hi,

I seemed to try everything I found at the net, but since I updated to Mac OS Monterey, Chinese and other non Latin Charaters don't show up. It works with Chrome and Safari, What's the problem.

I look forward to you help asap.

Thanks, Carolyn

Hi, I run windows 11 on my laptop. Whenever my laptop goes in sleep mode, all Firefox tabs closes automatically for no reason! and when I open it again a button appears saying (Restore old session) I need it Firefox to stay opened when the laptop goes to sleep. How can I fix that? Thanks in advance.

This is the issue: anytime I have firefox open, it is running between 16%-30% CPU usage (consequently running a train on my battery when not plugged in, and making the laptop fan go wild 100% of the time, reducing battery life from a normal of 2-3 hours to less than an hour). It doesn't matter if I disabled ALL addons/extensions, same issue; closed all tabs, issue persists; turned off "restore tabs after I close firefox", issue persists; cleared all but the last 2 months of browser history, issue persists; flipped all performance/use hardware acceleration settings on and off again, issue persists; loaded firefox in safe mode, issue persists. I've searched through all possible similar solutions given on these forums, and none of them have helped, I'm at my wits end here because chrome will not do anything near this on the same computer even with like a dozen tabs open.

I have firefox on multiple computers with windows 10, both laptop and desktop, and this issue is only occurring on a single laptop of mine with windows 10, a mobile i7 processor from 2018, 16gb ram, and a mobile nvidia 1050ti gpu, so it's not like this is an underpowered laptop. I keep my browser updated, my windows updated, my graphics drivers updated, and my addons/extensions updated regularly. This only started in the last few days and the only thing that changed was a windows update (minor not major), but again it's literally only firefox that is having this issue.

Hi,

I recently spent hours troubleshooting, reinstalling the browser + addons, editing profiles + themes, etc. and isolated the problem to the Firefox Color addon (v2.1.7).

When using the following custom theme the bookmarks toolbar does not show up, and the Extensions or Themes sections under settings do not work. Sync does not seem to work correctly too.

I believe this only started happening recently (within the past updates on or before 99.0.1).

Does anyone know if there's a bug in the recent Firefox update or if something else is the issue?

Thanks, HC

Firefox is unable to send the request at the startup, meaning it's just keep showing loading... and then opens the webpage after a couple of minutes. For example, if I open instagram.com: At the bottom it says, "sending request to www.instagram.com" and it stucks on that for some time as I'm not able to click anywhere in the webpage. And sometimes, it says, "transferring data from www.instagram.com" PC and the internet connection is fine. What could be the issue?

I have tried to Install Firefox Multiple Times. Firefox doesn't retrieve any pages when searched (Example:google.com). Even the Settings option is not opening. It is all blank Page.

Tried various options like Refresh, trouble shoot mode, Restarting, System Updates, Uninstalling Visual Studio, Changing Proxy. Nothing works. Kindly help on this solution.

Hello, Firefox has been getting worse with the latest updates to the browser. There are several websites I've attempted to visit that I received an error message when using Firefox, but opened without a problem with another browser. I am also having issues when trying to open attachments someone has sent to me in Outlook. I can read the email, but cannot open the attachments to the email. Are there any indications Firefox has been having these problems? If yes, are there fixes in the works?

Thank you, Marc

I get an ERROR when I try to access the OKCupid.com Site from my PC (Firefox, latest version) or use the link from the email sent to me by OKCupid (which should open in Firefox).

I’ve cleared all cookies and still get a screen that says :

“It’s not you, It’s us. We’re having trouble reaching our servers. Please try again”

Retrying does not help.

I can get access using Microsoft Edge.

Is there a solution for the problem ?

Thanks, Rod

I am using the bookmarks sidebar with Firefox on Windows 11. Several times a week, the bookmarks toolbar will become unresponsive - Clicking on links or folders to open/close doesn't work. Closing and reopening the browser solves the problem. I can still click on links on web pages and open or close tabs, just the bookmarks sidebar becomes unresponsive.

I have literally no extensions installed in Firefox, just the default Facebook container. No themes other than the system theme either.

Any thoughts to resolve the issue?

Thanks!

So i have been doing some research on a topic and had tons of tabs open in private tabs (I have this bad habit to start researching on some topic in private windows coz more user access this laptop ) , i had to note down all the info but then suddenly the firefox browser crashes and i lose all my tabs .. is THERE ANY WAY TO GET BACK MY TABS OR ATLEAST THE LIST OF THE SITES SO I CAN GO BACK ON THEM TO RETRIEVE SOME INFO ???

My application www.myfloorschedule.com has always worked well with Firefox. Beginning last month users report that they are being taken back to the home page while trying to work in the application. This occurs intermittently. Internally, our code does returns you to the home page when the session variable is null. I am able to replicate this problem. It occurs all the time when I turn on strict privacy. But with strict privacy off, it still occurs, although not on every page, all the time.

I suspect Firefox because testing with Chrome and Edge give no similar problem.

Thanks for any ideas on this. Terence

Hello,

I've identified a 1-2 seconds jank when I open a page containing a .webm player. This was a trial and error kind of thing but eventually, I realized that was the common pattern among the pages that were giving problems.

I ran the profiler and it's very clearly visible when the problem arises but here my knowledge of Firefox and its tooling falls short and I don't know how to find the root cause of the issue, that probably is not an extension since it appears on different Firefox accounts and in incognito mode.

Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

Hi

For some reason i have to format my PC, so i took firefox profile backup "a4bbv2q5.default" and after reinstalling windows and firewall I copied the content of a4bbv2q5.default to new profile "n9pw9oja.default-release". But as i start firefox the important files get renamed "corrupted" and a new file replaces, hence my restore of old profile is not completed. Screenshoot for reference.

Please help and assist.
