Diễn đàn hỗ trợ Firefox

I've been using Firefox for many years without a problem and have always liked it, but I've recently starting encountering a problem where Firefox consistently crashes after closing. After I close Firefox, the Windows Task Manager shows it still in memory. After a couple of minutes, the Mozilla Crash Reporter screen pops up informing me that Firefox had a problem and crashed, with an option to restart Firefox or Quit. I tried refreshing Firefox, which was a challenge because of the problem of hanging in memory after closing, but it did not resolve the problem. I also tried uninstalling it, then deleting the Mozilla folders and clearing out any references to Firefox in the Windows registry, and reinstalling it. I haven't installed any extensions yet; but sadly, I continue to encounter the problem. Any ideas about how to resolve the problem?

I should mention that I had bought a new SSD for my computer and migrated everything over from the old SSD to the new one. The problem with Firefox began after the migration. Everything else that was installed there works without a problem. I would be surprised if this is related to the issue considering I've reinstall Firefox.

I have updated my Firefox on PC to the newest version available (version 120.0.0.8720 as of 24/11/23 00:30 UTC). Unfortunately whenever I try to open it, it loads a blank screen and then crashes, and brings up the crash reporter. This has happened every time I try and open Firefox, even during Troubleshoot mode. I have over 180+ tabs and thousands of bookmarks on my account that I do not want to lose (I have not used Refresh Firefox for this very reason) but if I can't even access them on my computer then what can I do?

Please help me, I want to know how to fix this and keep my tabs and history. I am desperate.

Version 120 (PC) continuously crashes and asks me to refresh and nothing happens (including after rebooting) so I had no choice to uninstall. I normally trust your updates but I'm really regretting this one. Can you help me not switch over to chrome? Maybe you're already aware of this bug and will have it fixed soon.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

Hello!

I often log in to a service ticketing website to help my customers. Before emailing them I must reference the service ticket number somewhere in the email, but this is very difficult to do in Firefox. If I inspect the element this is what I see:

<em unselectable="on" style="width: 2161px;">Service Ticket #55474079</em>

I understand the unselectable attribute is on but even if I try setting it to off or deleting it all together the problem remains. Moreover, I've tried it in several browsers (Chrome, Edge, DuckDuckGo) and it works fine without any extensions or tricks.

In other words: only Firefox keeps me from selecting this very important piece of info.

Any help would be very much appreciated! I looked up help articles but nothing similar to my case. I did find an extension for the browser but I am afraid to try it due to security reasons.

Thank you!

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

xdg-desktop-portal xdg-desktop-portal-gtk

Firefox bowser stopped working suddenly. Tried uninstall and install multiple times with multiple options.

Still not working even after cleaned all Firefox related files using uninstall tools and installed again.

I am using a Dell Inspiron 3847 with the standard keyboard which came the system years ago

Recently, when viewing a large online page, when I try to scroll down, the scroll doesn't start until about two seconds after I press my scroll key (which is the lower-middle key of the 4 keys between my right-hand "Ctrl" key and the "0" of the 10-key keyboard at the far right of the keyboard).

This delay started happening a few weeks ago. I do not know whether something I did caused it.

How can I scroll my view starting immediately, rather than having to wait two seconds for it to start?

Hi,

I am running Firefox 108.0 on Ubuntu 20.04.5 and videos on Reddit don't play, they just buffer (?). Youtube works fine. I've tried the suggestions on this page: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#search but nothing seems to work.

Thanks

Hello!

I recently got a new PC, and every time I open up Firefox it instantly closes. I have tried downloading it on the Microsoft Store, it seems to work fine for 5 minutes and then it happens again.

Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on. But it didn't. I honestly have no idea what to do next. Firefox has worked on that computer before. Everything else works fine, it's just firefox that won't work. If anyone has any ideas, please let me know.

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

I have been using firefox for more than 4 years now. But from about a year, i m facing the issue with the Sudden High CPU usage in Windows task manager.

The task manager has 2 different firefox processes. One being actual instance i am running. and the 2nd being the automatically opened in background.

i have figured out whenever i have active internet connection and my system is on charging the 2nd task automatically starts in background and uses upto 80% of cpu usage. Ending the 2nd task form task manager doesn't affect anything. only the cpu usage drops. Also Closing my firefox instance does nothing to that 2nd task.

I have tried lot of solutions i found on community. Nothing seems to help. problem still persist. I even posted comments on ongoing threads. but no reply from anywhere.

this is the last time i m trying. if i get a solution its good. otherwise i am going to shift to edge. I have no other choice.

Screenshots from multiple dates are attached.

I have a blog hosted on Render. The base URL provided by them is https://parker-codes.onrender.com. This URL works perfectly, in all browsers.

I purchased a domain from Google and then linked a CNAME record to the Render one: https://blog.parker-codes.dev. This URL works in many browsers except for Firefox Mobile (on Android). I receive the error "Address not found. The browser could not find the host server for the provided address."

- I flushed the DNS cache and checked that it propagated across the globe. I used nslookup to verify the domain resolution. - I tested in various other browsers on desktop (Safari, Chrome, Firefox) and mobile (Chrome) and they all work. - I turned off mobile extensions. I also tried in a private window. Still no luck. - I reached out to Google support. They don't see any domain or DNS issues on their end.

From all of this, it appears that the Firefox mobile browser has a bug that can't load the site for some reason. It can't properly resolve the host even though many other browsers can.
