Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

Recently I have found that I cannot download statements from my bank account, also at the same time (2/3 months ago) I cannot access a Tesco website from Firefox. I can carry out these functions easily from Microsoft Edge, so why the sudden change ? Can anyone please help me to fix this in Firefox?

I have been getting the "new version available, download now nag for over 2 weeks, and I have the latest version. Still get this issue repeatedly every day. Starting to become an every hour nag to update and install latest version of Firefox. Refuse to use Microsoft Edge or Chrome, and will switch off Firefox too if not rectified.

The 125.0.2 update broke Amazon Prime Video. Firefox refuses to play ANY video, causes website to return a "That shouldn't have happened" error page. Prime Video plays just fine on Safari 16.6.1, macOS 11.7.10. Amazon says just to use Safari, but I want Firefox to work right.

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

Hello, dear Firefox Help people!

I keep a lot of tabs open in my Firefox browser (121.0 64-bit for Windows 10). Starting just recently, if I closed Firefox by clicking on the "X" in the upper-right corner of the window, then the next time I start Firefox it opens without my tabs! (It never used to do this before...) It's very disconcerting, but I found that if it starts up without my tabs, Ctl+Shift+N will open Firefox in another window--with all my tabs! I can then close the original window (the one without my tabs), and go on using Firefox in my normal way.

If I have Firefox running with my tabs present, and I close Firefox by using Ctl+Shift+Q, the next time I re-open it, all the tabs are there. (That's also the case when I close Firefox using the three-line menu and "Exit".) But I used to be able to close Firefox by simply clicking on that "X" in the upper-right corner of the window, and next time I started Firefox it would open with all my tabs intact. I'd like it to work that way again... What must I do to get it to return to working that way?

(Please note that under Settings/General/Startup, I do have "Open previous windows and tabs" checked...)

Thank you for any help you can provide...!

In the recent update to Mozilla, all of my shortcuts disappeared. I had many, and can`t remember them all. Is there any way to restore my shortcuts from what they were a month ago? If not, I will switch to Edge.

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

How do I disable the mozilla.com news popups? I keep getting annoying news popups with Mozilla.com written at the top of the popup. Todays was USAToday. I did not request this and I want it gone.

Fix the problem ! If I set up a set of bookmarks and web sites to be opened on startup of Firefox, then use them and save that list forever until I change it.

That is how you product worked until this week. Now, it sucks. And why does the header say that my options are controlled by my organization ? This is my private computer, belongs to me, not any organization !

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

I am having trouble sending tabs from my phone to my PC. My device is connected to my computer, and I can send tabs from my PC to my phone successfully, but not the other way around. I have no idea what could even be the issue, and I have only seen people asking about sending tabs from PC to Mobile, not the other way around. Is there something I am missing? None of the Firefox troubleshoot pages have helped.

When I search something in the adress bar I get the following screen when opening google (see screenshot) About this page

Why is Firefox suddenly not remembering any of my logins or passwords? When I go into Preferences > Security, the box to "remember logins and passwords for websites" is checked. When I click on saved passwords they all are there. The do you want to save box is there if I have changed a login, or added a new web site. I am not in private browsing mode. The problem seems to happen every time I install the latest Firefox update, or Windows 10 Pro updates. Some of my apps want to know if I am using a new device.
