Firefox 技術支援討論區

When typing comments on a web blog, after the spacebar is used, the first letter of the next word eliminates the previously typed space. So what I end up with is all words in a sentence running together. Tried other browsers and they work fine. Changed keyboard as well no joy. Typing is normal in applications like adobe, word, etc..... Only happens during Firefox use......... Uninstalled and reinstalled Firefox, also no help..... How do I fix ?

I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

Over the past few days FireFox v. 99.0.1 had been non-responsive on a tab.

Got to the point I had to close FF and tried to use cCleaner to clear cache/history etc.

However cCleaner could not proceed as it claimed FF was still open.

Using Windows Task Manager I found FireFox was "Suspended" (screenshot 1)

I then terminated the task - so cCleaner could proceed.

Then FF appeared to work OK. Until the next time....

It just happened a few minutes ago closing FF - using cCleaner - once again FF was "suspended" and had to be terminated in Task Manager.

On FF help it said Update to version 100 which I did BUT the update got stuck on the FF Update - for several minutes (definitely over 10 mins) so I had to terminate the FF Updater using Windows Task Manager (screenshots 2 & 3) again used Task Manager to terminate that.

FF appeared to open OK even showed the version 100 What's new tab.

BUT when I used FF help to check version I got Restart FF to update to version 100 (screen shot 4) Perhaps the last might temporary due to terminating the what appeared to be stuck Updater, but it was worth mentioning.

Any help appreciated.

I don't know when it started (quite awhile), but when I go to some websites even in FF safe mode, I wait a long time but get nothing displayed and it stops spinning/waiting (the circle arrow upper left stops). Occasionally when I reload, it comes up but usually it doesn't. Other websites it works fine.

In fact, if I browse to some websites, sit and wait awhile, then go to chrome or edge, type in the same website, the page displays even while FF is sitting there waiting.

ebay.com seems to work great, but for instance this morning, this one doesn't: https://www.crowdpac.com/news/741938 but sometimes this works: https://www.crowdpac.com then try it again (refresh) and it never responds.

And in fact, I'm using Edge to submit this question because when I browsed to https://support.mozilla.org/en-US/questions/new/desktop#search in Firefox/Safe and clicked on the Sign-In/Up button, nothing happened. With Edge it worked fine and I'm able to type this in.

Hello,

For a few weeks now, I have a lot of crash when using firefox (I'm on windows 10). Not the whole application is crashing, just the current tab that I'm browsing. It said that a random error occured and offer me to reload the tab. It then works but crash again a few moment later (irregular). I tried to update my drivers, to uninstall and reinstall firefox (even did a full wipe of the app and its files before installing again), I tried some old firefox versions but I always have the same issue.

When I check the event viewer I have these kind of error for firefox.exe : Faulting application name: firefox.exe, version: 96.0.3.8061, time stamp: 0x61f17d54 Faulting module name: xul.dll, version: 96.0.3.8061, time stamp: 0x61f17d85 Exception code: 0xc0000005 Fault offset: 0x0000000001e75563 Faulting process id: 0x1a84 Faulting application start time: 0x01d81552ce22efba Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: C:\Program Files\Mozilla Firefox\xul.dll Report Id: 6154e84a-b617-4067-a5f6-b49760fffb03 Faulting package full name: Faulting package-relative application ID:

Any idea on how to solve my problem please ?

Thanks in advance

I use Firefox a lot, and a couple of months ago, it started duplicating images whenever I ctrl-v'd the images into discord. Since then, I've completely reinstalled firefox several times, with no addons-I also tried the beta and nightly versions, and even Waterfox, and still run into this problem. It seems to be an issue that strikes a lot of firefox users, and I haven't been able to find a fix yet.

In short: copy image paste image into discord (it doesn't matter if it's ctrl-v or right click paste) two images are attached to the message instead of one

This only happens to some images, mainly .pngs. I have no idea what is causing this problem and I would appreciate some kind of fix.

Just installed Win 11 on a new SSD an dam having trouble downloading files. Some come down ok and others not. The attachment shows shows 2 Logitech files. I can download them with Chrome

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

Several sites I use (Yahoo, American Thinker) and occasionally other random sites won't load when I use your Add-Ons Privacy Badger, and Ublock. I get server can't be reached errors. I use ESET as my security app. Suggestions?

Since a few days, I keep experiencing constant crashes with Firefox.

In the most common way, a Tab will crash first, often followed shortly by the whole browser crashing.

Crashes occur on, but are not limited to, following pages: • YouTube.com • Reddit.com • Google Account Login • about:preferences • about:crashes • about:support • The very same Support-page I’m writing this on

Crashes still occur after: • Rebooting Computer • Clearing of Cache • Starting in Safe Mode (crashes in Safe mode) • Deactivation of hardware acceleration • Refreshing Firefox • Reinstallation of Firefox (Uninstalled with the Uninstall/helper.exe) • Use of Windows Deployment Image Servicing and Management tool (DISM /Online /Cleanup-Image /RestoreHealth)

Crash logs list: • Crash Reason EXCEPTION_BREAKPOINT Crash Address 0x00007ff88082381f • Crash Reason EXCEPTION_ACCESS_VIOLATION_READ Crash Address 0x000001f4465fffe8

I’m kind of out of options. Most support pages are 2 years or older, so I don’t really know if I’m experiencing the same errors as they did.

If there’s any more information required, please let me know.

Frequent crashes. I've run Onyx. Reset extensions. Reinstalled firefox. I've been using google maps frequently, so I switched to safari and that crashed too. Trying chrome now -- no problem yet. I'm wondering if GPU is at fault. I've ramped up cooling based on GPU. Still crashing. Tried holding down D and option D to test ram but I just get a command line on a non-responsive screen.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

Hi, For about the last month or so, the Yahoo mail tab closes itself after I click on an email attachment to open the download dialog box. This happens exactly 30 seconds after clicking on the attachment, whether or not I go on to open or save the attachment. It does not happen if I merely 'preview' the image. I don't know if all attachment types behave the same, but it applies at least to jpg and pdf files. The tab can be reinstated via History/Recently closed tabs.

Firefox does not crash, and there are no crash reports. In other respects this is similar to a previous post by 'eladopoulos' on 4/30/22, 8:17 AM (https://support.mozilla.org/en-US/questions/1375635).

Using Safe mode makes no difference. I had set browser.download.improvements_to_download_panel to False, but reseting to True makes no difference. Thanks in advance.

I'm running Debian Stretch and the packaged version of Firefox (91) runs fine but seems a bit dated. I installed ver. 104 manually and everything is fine except that there is no audio. I changed the setup Privacy and Security Autoplay to 'Allow Audio and Video' -- no audio. I've restarted in troubleshoot mode -- no audio. Other browsers, including ver. 91 of Firefox have no trouble with audio. Any ideas? On quitting I get these messages:

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

When I open Firefox, I'm getting ** 12 ** instances of Firefox opening up and spamming the hell out of my hard drive (even slowing down other processes), even without opening a page (I have mine set to not open any pages on loading Firefox). This is annoying and intolerable. I have looked around to find a workaround, but the only post was from last year, and gives instructions to turn off recommended settings, then says to set Firefox instances to 1, where there is no way to do that in that section on the version I'm running. So, how do I fix this? I want the hard drive spamming stopped.

I Am on desktop:

i5 9600KF (high performance mode) 16GB 3200mhz ram NVME... Windows 10 Pro x64 Firefox last stable

When I open Firefox tabs aren't loaded all at the same time, but they are suspended. So after that: when I switch between 6 tabs quickly - they start to open at the same time. And CPU usage skyrockets to 100% LOL! Given I Am on high end PC - this is joke! I was using chrome and had hundreds of tabs and Chrome doesn't even suspend them by default. They open all at the same time I think!

So there is something wrong! I tried troubleshooting mode and it was the same problem!

Thanks for help!
