Firefox Support Forum

After upgrading firefox to the latest version 110.0.1 few users are getting a prompt that firefox version is old and they need to create new profile.

"Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I have tried: -uninstalling/reinstalling newest version of Firefox -using run, firefox -p to open the profile -creating a new profile altogether -setting my default profile

Please let me know if there is something else we can try or a fix out there I haven't found

Whenever I try to launch Firefox on my windows 11 pc it always crashes even when I true the official fixes and install it through different means it always crashes on startup

I'm not sure whether it happens at current version of Firefox or already happened previously, but if you close your Firefox main window without closing your Private window first, all your session tabs will be lost when we launch Firefox again. Is there any way to recover my previous tabs?

I have problems with dragging files from downloads directly to my desktop. Now, in order to drag downloaded files I have to open the downloads folder, which is an additional step and a nuisance.

Is there any way to get the old functionality back?

Im using Firefix 111.0.1 (64-bit) on my Mac M2 2022, with the Ventura 13.2.1 MacOS

With the latest update of Firefox, my laptop, which is a high end DELL, is experiencing big difficulties just running a Firefox with 3 tabs open. the CPU usage is skyrocketing and it is also heavy on the memory. I am running the same 3 tab on the same websites as I have been doing for the past 6 months, but since the latest Firefox update, this has become impossible. What happened to Firefox? I have had no other significant updates but the Firefox update.

my facebook ends after a dozen posts with the error message saying reload bur reload does nothing I still can not scan down my facebook posts this only happens on Firefox no other browser has a problem

Hi,

As the title says, Firefox throws "We can’t connect to the server at m.imdb.com." error every time I try to open a page while everything else works like Chrome, Edge and when I ping via command prompt I get replies and other applications. (Win 10 64-bit with latest Firefox)

I think it's a system-wide problem but I can't figure out where. I was under the impression that it's a DNS problem but it doesn't even open IP addresses like 192.168.1.1 and it doesn't open instantly, no matter it's Google.com or my router IP, instant error message.

I tried everything I could find which are:

• Refresh, clean re-install with deleting profile directory
• clearing cache and data
• Toggling these in about:config: network.http.http3.enabled, network.dns.disableIPv6, network.dns.disablePrefetch
• Enabling/disabling my adapter
• Running a couple commands:

   ipconfig /flushdns
   ipconfig /registerdns
   ipconfig /release
   ipconfig /renew

   netsh int ip reset resetlog.txt
   netsh winsock reset catalog
   netsh int ipv4 reset reset.log
   netsh int ipv6 reset reset.log

• Setting proxy to None
• Restarting with Troubleshoot Mode (add-ons disabled)
• Removing Firefox entry from Windows Firewall. (I haven't installed any Firewall and Anti-Virus)
• WIndows's Network Reset
• Rebooting machine and router

I'm sure there are more, these are all I can remember now.

This happened some months ago but can't seem to remember how I fixed it.

The only way it opens sites is with a VPN that sets a system proxy and setting Firefox's proxy to "Use System Proxy Settings".

Cheers

'bold textpr end of file error, pages will not load have to constantly press retry. mostly in email and home page. I have reloaded deleted and reloaded still the same things '

Updated to latest Firefox, 111.0.1 64 bit. Browser is now extremely slow to load. Hangs up on some web sites. Lots of little blue time out circles. Almost unusable. Have to reboot to get the browser to load.

Congratulations your browser is useless thanks to your latest update. I am unable to open numerous sites that EDGE, Chrome and Opera open without issue. Firefox is my default browser. I'm about to switch to something else permanently because you've made it a total pain in the ass to use.

FIX IT!!!!!

Firefox is showing all the time "The connection has timed out. The server at xxx.localhost is taking too long to respond." on loading or changing pages on localhost. When calling the same URL everything runs smoothly using Chrome.

Environment: Firefox 111.0.1 / Ubuntu 24.04 / Apache/2.4.56

Which settings can I change in Firefox in order to solve?

I found that when starting Firefox on my school's WiFi, it starts up very slowly. Using `strace`, I found that it was taking it's sweet time making a DNS request to try to resolve my computer's `/etc/hostname`. After searching the Firefox source code with https://searchfox.org/mozilla-central/source/, I found that the only occurrence of `/etc/hostname` was in [SandboxTestingChildTests.h](https://searchfox.org/mozilla-central/source/security/sandbox/common/test/SandboxTestingChildTests.h). So I was wondering if it's possible to disable these tests when Firefox starts up.

I watch a live stream from back in the UK from talkSPORT daily. Lately I noticed that my video rate was too low and the play back was skipping and stopping. I run a 64gb Nvidia graphic card so it cant be that.

I normally run firefox and it's always the latest release. Today I tried it out on Chore and I had zero issues withe playback.

I can only come to the conclusion that firefox has cocked summat up. This is only been happening for the past past month or two.

I don't know if it's anything to due with Nvidia software or not but it needs to be sorted out. I've been using firefox since it started. I'm used to the ecosystem. I don't want to have to adjust to chrome.

Everytime I try to upload a file to my desktop, Firefox gives me the message File Uploader Not Responding then gives me the option to close or wait. if I wait, nothing changes.

I use Bing as my Firefox home page. Today, after a Windows BIOS update was installed and the computer restarted, the top of home page is cut off. I have to fiddle around to find the sweet spot to move the page down so I can see the tabs, the minimize and maximize buttons, and the close button. Zoom is set, as always, at 100%.

Confused as to why there 44 instances of FF showing up in task manager. Win 11.

ANy help appreciated.

My PC is running v slow.

No viruses as per MWBytes scan.

After a mistaken forced restart (inadvertent pressure on the shutdown/start key), one of the 3 windows I had open is invisible. It shows in the 'Windows" menu as one of 3 but when I select it - nothing. It does not show as a recently closed window in History. I have restarted Firefox multiple times, including deleting the xulstore.json file then restarting (a fix from another similar thread).

How can I restore this inaccessible window?

Thanks

I just started a windows 10 computer. When I try to go to google drive, I get this message:

____________________________ Did Not Connect: Potential Security Issue. Firefox detected a potential security threat and did not continue to drive.google.com because this website requires a secure connection. drive.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the website, and there is nothing you can do to resolve it. If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem. ____________________________

I also got this kind of message when logging into outlook, but I was able to click the override button to login.

When playing a youtube video, I can hear the audio playing and see the time passing on but the on screen video is just stuck even when buffered full clip. I check on chrome browser, this doesnt happen there. Reset firefox, the issue is still here

I get this error message and then it shuts down if I don't stop it by deleting it....

“Error while installing” :Expecting value: line 1 column 1 (char 0) Fire Fox then shuts down if I don’t delete it.
