Diễn đàn hỗ trợ Firefox

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!

I use gmail for both personal and work (business) account. I have both accounts logged in and open on Chrome and Firefox. On the Firefox browser every 5 to 10 minutes the web page shows error 001, and the page wont reload. Only fix is to restart Firefox. However, at the same time the same accounts are not having problems via the Chrome browser.

I have no add-ons or extensions enabled on the Firefox browser. I have already done a Firefox reset, that did not fix the problem. I have done a uninstall and re-install of Firefox, that also did not fix the problem.

Getting error message on mozilla when try to log into godaddy, same message does not occur on microsoft edge, went through all possible godaddy glitches, they say it isn't one of theirs, rather the browser

Hey. I have this weird bug on Firefox ( left window, right window is librefox ).

The bug is the " select text" thing. As you can see, librefox don't have this bug, edge same too. Already tried to reinstall, downgrade, update, delete all files related to firefox, deleted pref.js.I think I already had this on youtube for exemple, but not quite sure. I tried different mouses, but it's purely firefox.

While I'm doing my emails, I get a yellow error message: this page is slowing down your browser. To speed it up, close this page. That's my hotmail inbox. Happens often. If I close the hotmail then reopen it it works ok for a while, then does that again. And in general it's slow. Feels like firefox and hotmail are at war with each other...

Internet explorer works!

Hi! Upgrading to version 100 has made Firefox completely unusable for me. Every time I open it, the "Password required" popup appears, which is normal. However, whether I enter my primary password or click "Cancel", the popup goes to the background and I cannot close it, nor click on anything in the app. In fact, I cannot even close the app except from the upper menu bar (I'm on OSX). See the attached screenshot to get an idea. Please help!!!

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?

Firefox Freeze after today's update when attaching files on Gmail. Crashed multiple times HELP !!!

Attachment window opens on Firefox program files

Then as you search for your file the attachment window , it freezes the entire browser.

Since installing v100 I have had problems where tabs will not load anything. They will work fine for anything from 5 minutes, to an hour, then randomly just seem to hang. The only way to fix it is to close firefox and restart it, which is a PITA if you are trying to research stuff with multiple tabs and so on.

Additionally, some customers I support started getting SSL_Error_Bad_Mac_Alert errors... only on Firefox, and only when accessing google, and even then it might work fine for half a day, then continuously get that error- but open same page with chrome, and its fine. PCs on the same LAN also running firefox also had no issues with google at the same time as one of the effected PCs, but once updated also started getting the error intermittently (but again still not necessarily at the same time as each other). As you can imagine google is used a lot, and so this can be particularly painful. I have tried most of the suggested fixes for that error, and prior to the upgrade there were no issues.

Issue has occurred on both Windows 10 Pro, and Windows 11 Pro

Is there a way I can roll back one or two versions? It is really starting to become disruptive, and if it continues we will have to look at changing the deployed browsers completely.

Any time I visit a google page that has a map anywhere on it the page goes into a continual loop of refreshing until the google security page opens to make sure I am not a robot. When I click the captcha it reloads the page and the loop starts again. So then I entered about:config to turn autorefresh to false but it still does not stop the google page from a continual reload loop. What else can I do?

Hello, I have trouble with browsing Facebook, sometimes there is a huge memory leak (please check the first uploaded image), and as you can see in the second uploaded image, after I "end task" the Firefox tab that use a lots of memory, the Facebook tab crashed. The third uploaded image is the addons I have installed.

Is there a way to solve this? I go to about:memory and click on all there buttons in "Free memory" but that seems to have no effects.

Thank you for your time, Tom.

I did a refresh yesterday and lost my passwords. I have another computer where the passwords are functioning and I have the "old file" but I don't know how to use it. I clicked on the old file, but just came up with another file called EP7i0nok. It doesn't do anything but it just opens up and it doesn't have anything to restore data.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again?

In the past few days Firefox has stopped showing html pages on my other partitions. Has Firefox changed the way they are doing things or is this a new bug?

The screenshot below shows a web page I regularly use that I keep snippets and brief programming notes. It and all links on all partitions except the root drive are no-longer accessible.

I have used Firefox for over 10 years and never had this happen.

Any ideas what may have happened?

I run into this at least once a week, on sites that I know are completely legit, including sites that I recently visited successfully. Once it starts happening for a given site, I can't figure out how to get past it and regain access.

I've asked other folks to visit the same sites at the same time, and they can get through. I've tried accessing them on other devices on the same wifi network, and get through just fine. But I can't get to them any more on my main computer.

I've tried clearing cache and deleting cookies and data, and that hasn't helped.

I'm on Windows 10, and (now) Firefox 100.0. I'm in the UK, using Sky internet -- I don't know if that's relevant, but I didn't notice this problem before I moved here (from the US) last year.

As I said, I can still access the sites on another device (an iPad) on the same wifi, so I don't think it's the firewall in my router.

I don't have any antivirus installed -- just using Microsoft Defender. And I'm not using a VPN or anything like that. My browser privacy setting is "Standard"/

The only extensions I have installed are Facebook Container and LastPass.

What can I do to fix this? It's breaking the internet for me.

This is a horrible web browser that crashes constantly and is slow as hell. Even Internet Explorer is faster than this, and I am switching to that browser and am never reinstalling Firefox ever again.
