Firefox Community Forum

Ever since upgrading to Windows 11, my Firefox installation has occasionally been unable to resolve domain names of some websites. Example domains:

• apps.powerapps.com
• static.cdninstagram.com
• google.com

As I was trying to debug this, I discovered that the DNS resolution and connection timings are just over 30 seconds (see the attached image). This is highly unusual.

• The issue does not occur with other web browsers on my computer (i.e., Microsoft Edge).
• The issue has persisted across reboots.
• I have already reinstalled Firefox (and wiped the temp files and appdata profile before installing again).
• The issue does not occur with other devices on my home network.
• DNS over HTTPS has been manually disabled.
• Changing DNS resolvers in my Windows settings does not fix the issue.
• The issue is still present with a fresh, unmodified installation of Firefox.

Any help would be greatly appreciated! I love Firefox and do not want to switch to a different browser.

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

It has always been the case that when I closed Firefox, it asked if I wanted my open files saved and reopened when I opened the browser again. I needed to restart my laptop and I decided to close Firefox first. It asked if tabs should be saved and I said yes. After I restarted the laptop and reopened Firefox, all of my open tabs (I think about 35) were gone. Can I get them back?

Hello, any best practices for converting Firefox bookmarks once they're exported? The exported_bookmarks.html are an html file which are impossible to edit. Converting so the data for folders, titles and urls can be edited is what's needed.

I tried Vi with some Regex code, however the cleaned file is not so clean.

I am suddenly unable to login to my iCloud account using Mozilla Firefox. I was always able to do so before now. I am able to login using Microsoft Edge browser. I have disabled the Firefox pop-up blocker but still not working. When I input my username and password, iCloud sends me an authentication code... but that next pop-up screen from iCloud having a place to input the code does NOT pop-up, so I cannot enter the code. That pop-up screen comes up in MS Edge. Any help is appreciated!! I'm running Windows 10

Best regards,

At the beginning of 2025, I created a private theme and installed it locally (Windows 10), consisting of a manifest.json and a GIF file. It worked perfectly. Now, on Windows 11, I'm trying to use the theme again, but when I upload the file (.zip or .xpi — via about:addons -> Install Add-on From File), I always get the message that the file is corrupted. However, if I test it temporarily under about:debugging, it works immediately without any issues.

I would really appreciate a solution! <3

I just had another credit card get fraudulent charges. I have no clue how they are getting my card numbers, I have pulled all but 1 from anywhere online, but they just got another one. I couldn't get Mozilla VPN to work it just quit working at all. I turned Pocket off but I'm still getting 17 to 18 instances of Firefox. Dont know where to go now. Thinking of pulling the plug and starting over.

I would like to eliminate the websites which are done by an AI in my brownser. Especially those were no redactor is mentionned. Is it possible ?

Thanks

Greetings everyone,

Earlier, when I opened Firefox it didn't restore the tabs and windows I had been using from about 2 weeks ago. I tried looking in "History" in the Firefox menu but it only displays tabs and windows that I've closed and it doesn't have the tabs and windows I had actually open.

I've had the same Firefox settings since I first installed Firefox a few years ago and this is the first time this has happened... :'( :'( :'(

I must have had about 70 Firefox windows and even more tabs within those windows so this really hurt me... :'( :'( :'(

Thank you for any help!

msn.com comes in just fine on Firefox on Windows 10, 8, 7 computers. What's causing the undefeatable block on Windows 11?

Suddenly I cannot log into icloud from your browser. I can log in using other devices and other browsers. Fire Fox gives me an error message "Failed to verify your identity. Try again"

we use fire fox for all our bookmarks. We are unable to login to our bank of America account, it shows our ID but it will not allow us to enter any password.

I am running Firefox on Windows 10 64-bit, and I have lots of windows and tabs open. Occasionally I will get a message from Windows that I am running low on disk space. Recently I got the message, and I saw on my C-drive" "336,044,032 bytes free". After I did an Exit in Firefox, I saw "10,082,402,304 bytes free". The space that was freed was in the pagefile.sys file. Is this normal?

I just received a toast from a sidebar app. Unsolicited notifications are the fastest way to get me to dump your app. I recommend Mozilla implement user-level control to disable notifications from sidebar apps. In theory, Mozilla is already supposed to be respecting my preferences on notifications. I have authorized notifications from only one website, and it wasn't the one for which I received this notification. There's a disconnect there.
