Firefox 技術支援討論區

I am getting more & more frustrated and exasperated, as simple browsing has become tortuously slow, with many sites taking forever to load, or only partially load, or have to be refreshed a couple times, to finally get it to load. And videos constantly freezing up, despite lots of free RAM, and a very high-speed internet connection. I assumed whatever was causing this would've been addressed in the last update, or two, but no, it's only getting worse.

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

Every now and then my firefox does not respond when I click on any links on any webpage. It only works when I clear the browsing histories and cookies for last hour. This happens like every 15-30 minutes and is very annoying that I have to keep clear off the history.

Just today, firefox began slowing down and soft crashing for minutes at a time. During this time, I can interact with websites, but it doesn't change the visuals or show that anything has changed. new tabs open but don't show up, youtube video audio plays but the screen remains fixed. Firefox usage for just 7 tabs is well over 5 gigatybes of ram and 10-20% cpu at all times.

I attempted everything on the help page, including: killing and restarting firefox, updating firefox, updating windows, restarting my computer, killing firefox and rebooting again, disabling extensions, and updating graphics drivers.

after rebooting with the new windows update, firefox ran smoothly for a brief minute and showed normal cpu/ram usage, but quickly climbed back up to pre reboot numbers.

Ever since I updated, typing has become incredibly challenging... There's big delays in the words showing up, letters come out in the wrong places, & it doesn't improve even when I clear cache, clear memory, & refresh pages. I don't know what else to do. Should I delete and re-install Firefox, or replace this with the previous version?

I had tried everything. I have deactivated all FOUR of my plugins and started up Firefox again. I have uninstalled and reinstalled a fresh copy. I installed Firefox on an SSD even and it is still painfully slow. I have the same plugins and such on Chrome and that one opens up immediately. So I have been using Chrome a lot more lately because Firefox is opening slowly these days. Takes 15-20 seconds for Firefox to open every single time. I have deactivated each plugin one by one to see if they were causing the issue and sure enough, all of them were clean. Firefox still opens slowly.

On an unrelated note, I have been using Chrome a lot more lately also because some things on a webpage don't work on Firefox. I can't explain it. Like on the hickory farms website, I click on the Add To Cart button and it looks like it is being pressed, but nothing is added to the cart. This type of thing happens across the internet on many different sites. When I go to Chrome, everything works as it ought to. I have my settings set to Standard in Privacy and Security. I don't know where else I have to check and change things to get those buttons and other links and such to work.

My Firefox opens pages slowly every time after I used it for months, and clearing the cache doesn't help. However, if I create and use a new profile, it gets fast again. What could be the problem?

For quite a while I am using Firefox and had no issues, but recently, with new version , I am constantly facing two issues 1. the initial load of a page takes more then 30 seconds , sometimes 1 minute, but after the first page has been loaded if I open another page , it will be as usual 2. Completely random and without any sign of slowing down the OS - the OS freezes - nothing works at all and I have to restart it using the power button. ( and this happens when Firefox is open so I doubt Firefox)

version Firefox Browser 91.0.2 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

This past week I have noticed while using google workspace it seems as firefox will time out. This causes my gmail to show errors because it is not connected any longer. It also seems that when this does happen I can't do anything through the firefox browser such as search or browse the internet until I completely close and re-open firefox. I would like to know what I can do to resolve this issue. I have refreshed, uninstalled and reinstalled, and tried about:config settings that handle "timeouts". Please I need assistance asap with this issue.

Firefox stops working several times a day & cannot access websites. PC is connected via Ethernet to the modem/router. I get a message website cannot be found. I called the ISP a couple times & they show me connected to the internet.

Firefox will not completely close & let me run it again. Task Manager lets me remove all but one occurrence of FF, which prevents me from running another copy of it.

I end up restarting the PC several times a day to get connected again.

The last time I was looking in Control Panel > Network Connections & that window froze & could not close out of it. I could open FF over the Control Panel window but could not run FF. I let it sit while using a wireless device to look up stuff. The monitor went to sleep because there was no signal, probably because the PC went to sleep. I could not wake up the PC & had to power it off.

Another time Network Connections > Local Area Connections was stuck on "identifying..." and never found the router.

All this started happening after I tried a USB wireless adapter & installed its driver & Cisco software that got installed with the driver. I have uninstalled all this & updated the wired network adapter driver.

I tried to restore Windows back to an earlier date a couple times but a message said the restore was not successful.

Any suggestions would be appreciated, Thanks

Hello!

I got this issue when i am clicking on input tools (on screen keyboard) on google search page,it opens up with a 3-5 second delay and this problem started after i installed version Firefox 90.0.02 64 bit.

My OS is Win 10 64bit. All updates except KB5004237 are installed.

I do have a couple of add-ons like Default Bookmark Folder and uBlock Origin and i even disabled them but still the issue stands with input tools delay.

I also refreshed my Firefox but that didn't help either.

Any solutions to this issue?

Firefox is slow; so slow I have to use another browser, Brave, to get around this.

It is not about 'how many open tabs' or 'what extensions are doing'. I can have one profile open with one tab and still wish there would be a better response.

I have lots of profiles. I think the performance was better when I first started Firefox on this computer. I wonder If I eliminate profiles will I get a better performance.

How do I go proving this? - How easy can I take the profiles folder copy and rename it then start firefox with a profile folder and only one profile and one tab then What?

I did not gain a significant advantage in the load times for firefox. The load time for the browser with only the one empty tab 22 - 26 seconds . The load time for yahoo.com main page 31 -36 seconds. The load time for a link on the yahoo main page 20 - 22 seconds.

The question was "does having a large profile folder slow response time for firefox"? I believe I am seeing that this is true. When I load the yahoo profile it can take 10+ seconds more to resolve the main page and up to an addition 5-7 seconds to resolve the opened tabs.

Know that the browser was the only user process opened at the times of the tests. Know that the internet connection is the primier package and I have been monitoring the speeds frequently recently. I am good with the internet connection times. Know that I know the quick fixes and either there was no improvement or the inconvience of doing with out dark reader is no option.

Now understand I did not run these tests through a testing suite. These test were a couple one offs I used to form an opinion. Everyday usage forms an opinion in everyday users without hard data to coincide with the usage.

In the past three weeks, I have been experiencing issues with the Firefox browser on my iMac MacOSX. First, the browser, after some amount of time of usage, seems slower. Second, if I keep windows with multiple tabs open overnight and then try to use them, they don't seem to function. The YouTube videos will not play. I can't move the tabs. I need to close the tabs and window altogether to get YouTube to function. Lastly, as of now, I can't even select and move tabs. I have never experienced this problem with Firefox on my iMac.

Prior to this I don't remember having these issues. What has changed?

When I use firefox, it gets slower and slower over time to the point where it's a chore just to type. And this is on a recent MacBook pro. Everything else is fast. But Firefox gets unusable. The UI should not be a bottleneck like this.

Retarting speeds it up for a while, but then it gets slow again in a few hours.

Is there some kind of profiling I can run that I can use for filing a bug report?

I am hoping someone from Firefox Development sees this and that something can be done for those of us who need to have several tabs open simultaneously. I often find myself engaged in research that for convenience requires that I have several tabs open which eventually leads to browser slow down, hanging, and sometimes a crash. Im convinced this is the correct analysis since defragging the ssd fixes it every time. I believe it would be very helpful if Firefox were to add a compressor to its file storage routine, first blush thoughts, possibly one compressed file per tab. When I get into heavy research I find myself defragging sometimes several times in a day, which temporarily fixes the problem. Any chance this can be added, or if anyone knows of a fix to this issue? rgds, j

I have to go into task manager to stop background processors from freezing my computer. Closing background processors in disk and memory. Sometimes there are as many as 10 background processors running but it seems to be a only a few and can't tell which one's until I figure it out. Sometimes I can by the amount of usage. I have to do this several times as I use my computer.

In Email, with every other click on a mail item, I get the message "Firefox is not responding." After 15-20 seconds the mail continues, but the same thing happens again, and again. Checking the mail is nerve wrecking.

Hi, since the last update, Firefox is taking a huge amount of memory and slowing everything else on my PC right down. Right now this support tab is the only webpage I have open, yet you can see in the screenshot there are 31 Firefox processes running, and over 1G of memory being taken. I've followed all the help threads and taken the steps in them - it's made no difference. Please can you help me find a way to tame Firefox. Also - I'm really not an IT expert at all so please can you tell me in very simple language :)

For the last two days and multiple times loading the firefox browser, it has taken about five minutes for the browser to load on our Dell Inspiron desktop, running Windows 11. Nothing happens for about one minute, then the spinning blue circle appears, then firefox starts to load, then the screen goes back to the desktop, then a black screen appears, then some white rectangles start to appear across the top of the screen, then the screen goes back to desktop, then back to the black and white top-of-browser window that is still trying to load, and then finally after the five minutes, our home page loads. However, clicking on a bookmarked website, or typing in a website in the address bar results in a 2-3 minute wait for that site to load. And this happens time after time with the computer still on, and also startup after startup. If this should continue for a few more days, we will start using Google Chrome or Microsoft Edge, and also cancel our subscription to Mozilla VPN. This cannot continue!

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!
