I find that my desktop browser firefox is very slow or doesn't work at all on a lot of websites like amazon or fortnine.

My internet connection and computer are not the issue: 270Mbps (wired connection) Processor AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz) Installed RAM 32.0 GB (31.1 GB usable) Graphics card NVIDIA GeForce RTX 4070 Ti SUPER (16 GB) Storage 3.58 TB of 10.92 TB used System type 64-bit operating system, x64-based processor (Windows 11)

My old PC and my mobile phone runs these website fine.

Sometimes the website will work for a moment, but stop and just load for ever after I open a new tab or clink a link. My task manager doesn't show any ethernet usage despite the tabs indicating they are trying to load. Refreshing the tabs does nothing and no matter how long I leave them they don't load. All my drivers, OS and programs are up to date. I have disabled my enhanced tracking protection and I don't have any adblockers. I have tried using the CMD "ipconfig -renew" and using ccleaner to clear out my cookies and cache but, nothing seems to have any lasting effect.

I am losing my mind trying to fix this. Why can I not browse the internet on my PC?

Any help on this would be amazing and much appreciated.

Sincerely, Calvin

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

This what you said: "Today we’re introducing a free built-in VPN in Firefox, a new IP-protection feature designed to keep you even more private while you browse. We’re starting by offering an industry-leading 50 gigabytes of free VPN-browsing each month." But all I see are the paid options. I want to try before I (might) buy. After all, you constantly preach that we have to be careful & trying to be careful.

I have completely cleared relevant history. I am in the UK, so only use Amazon UK. Yet, even within a day of removing all trace of amazon.com, it shows up again in the list of top sites on a blank tab's address bar suggestions. (.com is not in bookmarks, shortcuts, or recent searches, which are the only other selections)

The only explanation I have for this is that amazon.co.uk is making back-end calls to amazon.com and polluting whatever mechanism is used for this list – even though the browsing history as I can see and manage it does not include any references to amazon.com whatsoever.

Please, either:

• tell me how to get the browsing history as shown in the new tab's suggestions to respect the browsing history as recorded and manageable, or
• tell me how I can have control to blacklist certain sites that contaminate the list despite there being no record of them within my browsing history

The only other detail that may play into this; the first time this appeared out of nowhere I suspect was also the point at which the Suggestions from sponsors magically appeared in settings, and was on by default. Ever since then, getting rid of amazon.com has been a Sisyphean struggle, as though unchecking the sponsors option were being ignored.

I have looked at some of the comments about Firefox automatically opening pdf docs. Myu concern is twofold. Most importantly the password in the doc is somehow being overriden; that is a severe security issuen for me. Destroys the whole concept of security. Makes me very uncomfortable and may discontnue using Forefox after more than 15 years. Secondly this caught me by surprise; it only occurred for the first time this morning. How can i overcome this to prevent Firefox from performing merely as a browser?

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

when i use Chrome or edge to access yahoo email I can write & edit. when using Firefox browser; I cannot write & edit/highlight/change text colours etc before sending. tried deleteing & re-installing Firefox . please help. Driving me crazy rsvp

I run the current version of Firefox (152.01) under Windows 11 Pro on a Dell Inspiron 15-3530 laptop. More and more frequently, I'm getting "Access Denied" messages when I click on a site link t56o an internal page. This happens on several sites, most notably Dell.com. I get the error in Troubleshooting Mode, and clearing the cache doesn't help. I've searched the information here, but all the responses seem to involve Windows 7 or Windows 8, not Windows 11. Can someone tell me how to resolve this situation in Windows 11?

Thank you.

Hello. I have two questions about settings. 1. I want to hide the "Take Screenshot" option from the Firefox right-click menu. 2. I want to hide the "Original Profile" option from the options that appear when you click the Firefox hamburger menu.

I'm asking about these two points. 1. I'm trying to hide the "Take Screenshot" option, but I couldn't find a solution even after searching. about:config ↓ extensions.screenshots.disabled ↓ From true to false ↓ Even restarting Firefox didn't hide the "Take Screenshot" option. 2. Regarding hiding the "Original Profile," I can't find any information about this option, so is it impossible to hide it? I'm asking about these two points.

On last Firefox update my Password manager was blanked out. I had no username/passwords in my Password Manager although I had previously had over 100. I managed to recover it by logging in to my Mozilla account but now have access to over 7000 of other peoples usernames and passwords on my password manager. You seem to have a major data breech or is this a quirk I don't understand? These other names/passwords show up when I try to log into certain sites, such as Schwab for example, and I have to pick mine out of a host of others to fill in the login info. What is going on?

Recently, I've been having a problem with signing in to things via my Google account – the problem being that I can't.

Whenever I click on the "sign in with Google", it redirects me to the "accounts.google.com" page, prompting me to choose my account, but once I do, I get redirected to "accounts.google.com/gsi/transform", which is just a blank page with nothing in it (see image attached).

I know this is not a problem with Google, as I have no problem signing in anywhere else.

This happened to me once before, but the reason was one of my extensions, which for some reason interfered with the sign in; however, this time this solution does not work. I tried disabling every single one of my extensions, turning all kinds of protections in the settings on and off, deleting all cache for all relevant sites, but to no avail.

I of course also tried looking this problem up on the internet, but whenever I found someone with this problem, the solution that worked for them was always just disabling an extension.

Thank you for any answer.

Yesterday, Facebook started to take longer and longer to load a page. Whenever I tried to post something and it took forevahhhh for it to show up on the timeline. I had to reload and repost several times since yesterday. All other websites are loading up just fine, but Facebook has taken as long as 30 seconds, sometimes even more before it refreshes a page.

Then.. it got worse. All I could see was the Facebook logo in the middle of the screen and nothing else.

Then it got even worse. As of this morning, I can't even get any results when I google Facebook! I put Facebook into the search bar, click return -- and nothing happens, absolutely nothing.

I'm not seeing any problems with any other website. I have already restarted my modem. I have already cleared out the cache and the cookies. I have restarted my laptop three times. I even looked up Downdetector, but there aren't any problems with the website in general.

Those are all the solutions I've found when searching about this, but the problem is only becoming worse, with everything I try. If there's something I need to change in Facebook settings, I can't do that, because now Facebook is completely inaccessible.

This is only happening on my laptop. Mobile is fine.

Even when I open a new tab in Firefox, the focus remains on the address bar. I'd like to know how to fix this. When I open a new tab, the address bar gets the focus, which I find inconvenient. Is there a way or setting to prevent the address bar from getting the focus and instead focus on the search box in the middle? I've searched online and tried the "settings in about:config" suggested in the search results, but it didn't solve the problem. Is it impossible? Firefox 153.0.3 64it

I don't know who was the absolute [edited] to have the idea of forcing updates while the user is still working on the browser by shutting the browser down. Can someone else help me understand how to stop this nonsense??

And yes, I had the option "Check for updates but let you choose to install them" selected, and I'm still being molested by this forced restart """feature"""!

Every time I'm in the middle of an important work session, Firefox will suddenly refuse to open new tabs and prevent the ones that are already open from connecting and receiving updates. It erase private tabs and messes up everything!

I was in a call with my boss, and it got dropped because Firefox decided to update?? And DEMANDED that I close the browser IMMEDIATELY to continue using it????? What the hell???????????

I've only been running into this problem in the past few months, and I'm honestly shocked by how little uproar I'm seeing online about this bug. This is by far the worst think I've ever seen in a browser.

Anyway, I appreciate any help. I saw a trick to permanently disable updates, but I don't want to disable them. I just want them to be installed either when I CHOOSE or when the bloody browser is NOT in use!

Previously downloading files did not close the source website. Now when downloading a file, the source website is closed. Requires logging into the source website for each file downloaded. How can closing the source website be stopped.

I'm using Firefox in Windows. I lost all of my bookmarks... never mind how, I think I can prevent it from happening again... and I'm trying to figure out whether there is a way to recover them.

Looking in the profile folder, I see three profiles. One is listed on the about:profiles page, and is identified as the default. The other two aren't listed there at all.

I need to select each of those other two and see whether my bookmarks can be recovered from them. But how. The about:profiles page has a button for creating a new profile, but not for adding an existing profile to the page. Either it's listed there or it's not.

It seems to me that I could create a new profile and make it the default folder, then quit Firefox and replace it with a copy of one of the profiles I want to investigate. However, I lost my bookmarks by doing something similar to that, so I'm wary of doing it again.

Can someone explain what is happening here--why there are three profiles in the default profile's folder but only one list listed, and why there's apparently no provision for making Firefox list the others?
