Firefox Support Forum

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

Starting about a week ago, when I use Firefox 124.01 on my Windows 10 PC to visit Ebay, the pages show in Portuguese, and the country shows as Brazil. I'm in the USA. This problem does not occur when I use Chrome, Opera or Edge. Any idea about why this has happened and what I can do to fix it. On Ebay, I can manually change the language and location, but if I close Firefox, the problem returns. I'm using the version of FF that keeps no cookies or history. Thanks

I hope this applies here. I tried using the "-p" command fro Librewolf. Wiped out my sessions and settings.

Is there a way to do this in Firefox and or Librewolf?

Starting on 12/1/23 Firefox browser on Windows PC is Not Responding while loading up bookmarks toolbar. Switching to "Never Show" is only way to load the browser. Trying to open or manage bookmarks freezes up the FF browser again.

TO MOZILLA DEVELOPERS

In spite of hundreds if not thousands of users reporting this issue over and over again, and your suggested workaround to reduce memory usage in the settings that doesn't do anything - FIREFOX is still using unacceptably HUGE amount of memory.

With just FOUR (4) tabs open in one window, in the Task Manager I can see 17 (!!!!!!) Firefox windows open using 830 MB of memory. The highest usage of all my apps including memory hungry media apps. It's using THREE times as much memory as my Adobe Audition processing edits of a 1.5 hr audio with several clips.

This is insane!! You have gone crazy with caching to the point of making this browser unusable.

It's freezing up and crashing my Audition so before I work in it I must shut Firefox down completely - and I work on a powerful tower PC designed for media.

If you don't seriously cut back on this insane caching for the sake of browsing speed IN THE NEXT UPDATE, I won't be using your browser at all, it's simple as that. I'm already migrating my bookmarks and setting up Chrome which uses about half the memory that Firefox does with the same tabs, and I suspect that many users will follow suit.

The workarounds you offer DO NOT WORK. Any app that uses more than 500 MB of memory at any give time on my computer - goes.

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.

The problems occurs with all PDF file both local and from the internet.

The attachments are highlighted in blue in t he opened PDF file but cannot be opened. There is no way to click on the attachments.

Attached is a screen shot of one PDF file because I cannot attached the PDF file itself

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

If I have many tabs open, and pull one away, instead of the previous tab saying in focus, it clicks to a different tab.

If I have 5 tabs open:

1. Tab1
2. Tab 2
3. Tab 3
4. Tab 4
5. Tab 5

I'm focused on Tab 3. If I pull Tab 5 away, it snaps me into Tab 4 even though I was previously on a different tab.

I think this isn't a bug but not desired?

Where are my answers ? Could you email me the answer of my yesterday numerous questions. At first: HOW CAN INSTALL JAVA SCRIPT ??? I wish you get this problem with your system 100,000 times and maybe you will do something

My original question was how to prevent McAfee demands to be installed. The reply was "That isn't a Firefox issue but McAfee support to resolve for you. Also check with McAfee site and support about their software issue. Also Firefox Browser doesn't do popups to buy a product or software. " However the title of the popup IS Firefox. Would you suggest that McAfee is the originator of the malware?

Hello,

this topic is about two things.

1. How do I reset the data of the built-in Protections Dashboard without resetting all of Firefox?

2. and probably more complicated, how do I stop Firefox from checking for "Login breach information"?

I do already have and always had "Show alerts about passwords for breached web sites" in options disabled. Still the Dashboard shows that "1 password stored securely.".

Mozilla says "[i]Firefox Monitor warns you if your online accounts were involved in a known data breach. For more information, see Firefox Password Manager - Alerts for breached websites. To get the latest login breach information and more, Firefox connects to firefox.settings.services.mozilla.com/i"

So now I've gone as far as blocking "firefox.settings.services.mozilla.com" through HOSTS. Still the Dashboard shows that "1 password stored securely.".

Why is it still checking? How is it still checking? How do I stop this?

The solution given by cor-el works very well.

Thanks cor-el ! I needed that.

But you won't know it until you access more unique folders than you already have in the list.

For instance, when you access the 8th folder that is different it will be sticky, when you access a 9th that is different it will be sticky. Kind of like a "most recently used" list. You won't see the extras until they happen.

Solution given by Cor-el: There is a pref on the about:config page that defaults to 7 to set the number of entries to show in this list of recently used folders.

- about:config => browser.bookmarks.editDialog.maxRecentFolders = 7

I am on Windows 10 on a relatively new Dell Laptop. Only two years old. All of a sudden when I go to AndyMark.com it displays in a menu on the left as if I'm on a mobile device. Looks like either Windows has changed indicating I am on a mobile device (which a laptop is mobile) or Firefox has changed and defaults to mobile for Windows? Selecting ask for Desktop View is no longer available. I do not want Mobile view and the mobile view on my laptop for this site is not useable. I have been using Firefox since 1990. Never had this issue before. Please help.

Firefox on my other laptops and desktops with linux see the site fine. Chrome works. Edge works. But my preferred browser has an issue.
