Firefox 技術支援討論區

When watching videos on YouTube or Amazon Prime, Firefox will eventually stop recognizing keyboard and mouse input in all windows and tabs. This can happen after just a few minutes of video or after hours. It affects nearly all input: typing or clicking in webpages, the toolbar, the address bar, etc., though I can click the 'x' button to close tabs. When I close the final window, a dialogue will appear stating that Firefox is non-responsive and allowing me to kill the process. This seems unusual, because the OS's system monitor indicates there is plenty of unused and available RAM and CPU resources. Firefox behaves normally after restarting.

OS: Xubuntu 22.04 Firefox version: 120.0 (though previous versions have been affected for the last few months)

For a while now, several bank credit card sites are not working correctly when I use my Firefox browser. It did in the past and I didn't have any problems but lately I'm having these problems happening on sites I've used for years. If I use another browser it will work with no problem. In fact after talking with some of the support people at some of the sites that won't work, the suggest trying another browser which works fine. I'm talking like American Express' website which I use a lot. There are other sites other than credit cards that are not working correctly and again, their support agent will tell me to use another browser. I have tried different remedies like clearing cache, history, etc. I only use few addons like AdBlock which helps to cut down on trackers and information gathers. I have set my preferences to clear out my history and cookies. I have used Firefox for so many years without problems and with the same addons without any problems. So what is causing this to happen? I do enjoy using Firefox but if I have to keep changing over to another browser so sites will work, then maybe it's time for me to stop using Firefox.

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

Safari is showing the links seen in blue after each line but FireFox is leaving them out. Some type of bug or coding problem. This began happening 3-4 months ago. It used to work fine on FireFox. Would love to stay using FireFox and avoid the Safari thing. Love the browser!!! Mark Miller

My Dell Laptop INSPIRON 3793 running the Firefox/Mozilla Browser when I stream in Youtube or LiveNews periodically goes into the images in the photos I uploaded here. I am compelled to do a hard restart. I have been working with Dell Technical Services and they indicate they have no history of this issue. I am running Windows 10. My system has all technical updates including current drivers . I really do NOT want to move off FireFox but I getting pressure to run another Browser and wait and see if the problem surfaces. Is there any history of this issue with this Firefox. Any help or insight you can provide would be greatly appreciated. Thank you, Cate Brown

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

I just downloaded Firefox on my new Windows 11 computer and I'm having this problem where I try to open it and it immediately closes. It just flashes on the screen, I tried downloading it off of the Mozilla site and the Microsoft store and both times I've been having this issue. It doesn't show up in task manager when trying to open it, my computer is updated, and I'm connected to Wi-Fi. I have a video of the issue but it wont let me put videos here.

Firefox keeps crashing randomly, sometimes at startup, and sometimes just in the middle of a session. Sometimes just one tab will crash, and other times it'll be the entire browser. I ran it in troubleshoot mode and it still crashed, so it's not caused by an extension or anything. It never used to do this before and I don't understand what's causing this issue.

Im running Firefox on Apple Silicon and I really do wish that there was a way to change settings to adjust experience when using the browser. As for my current needs I wish there was a barebones mode I could enable because currently it's an energy hog and I am becoming discouraged to continue using it with this inefficiency.

Ill explain my use case, I do lots of research for school, and tend to work with 30-50 tabs at a time and by simply having Firefox open it drains my laptops' battery 3 to 4 X (times) faster. While the same tabs on Safari and even newly released DuckDuckGo Mac app can run those tabs for days while still sipping on battery.

another occassion is during my job search, these tabs will stay open for a week or two as I open jobs im applying to, using 'Skillsyncer' and bunch of gmail tabs. I prefer my laptop to lose 5% battery in 2 hrs instead od 3 minutes.

As things are now, Firefox is not well optimized and would like to let the Firefox team to add the mentioned functionality above. Sadly there's no way to reach out to their team and am instead forced to post here. For now I will refer to Firefox to 'Firefix' as there's plenty to fix.

When I open firefox for the first time or after reboot or logout the internet doesn't connect immediately and it need almost 1 minute or more. I tried so many solutions, but they didn't work. If I reset Firefox, then the problem is fixed, but after some days, it's the same problem.

I've tried to login to Falcon using my usual Firefox browser and it's struggling to load and just whirling around.

It was working fine before Christmas, so has been an update from Mozilla that's causing an issue and do you have any recommended fixes.

Thanks

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.

Hello,

We are using a Sharepoint site with an embedded page, and when clicking this page it brings us to this support article. Is there any way we can edit the settings in Firefox to allow for this page to open? https://support.mozilla.org/en-US/kb/xframe-neterror-page?as=u&utm_source=inproduct

I love Firefox and am a committed user, but on only one of my PCs it runs so slow that I am considering switching browsers. The slowness happens most of the time, but not all of the time, except when I open more than one tab, when it is all of the time. (Neither Chrome nor Edge have any such problems.) The loading time for pages is agonizing, and I have tried the following:

• Clearing Firefox's cache (which usually fixes the problem for a day or so)
• Resetting Firefox (which usually fixes the problem for a day or two)
• Using all combinations of Performance settings (using/not using recommended settings and using/not using hardware acceleration

I am running the same Kaspersky software on this PC as the ones on which Firefox runs well, so I don't think that is the problem (although I'm not an expert tech user, I admit). I'm running an AMD Ryzen 5 2600X with 2x8 GB DDR4-3000 RAM. Please advise.
