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 on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.

For the last day or so, Firefox is refusing to resolve any web pages. I have had to write this in Safari, so I can't share the data from Firefox. Sorry.

Please help, thank you :)

I like the Firefox browser and Firefox was working fine for months but Firefox did ask me to do another update today. I did the update as requested and after the update Firefox will not connect to any websites on my desktop despite an excellent internet connection. I cannot find anyway to contact Firefox directly. For major problems such as a 100 percent failure rate to connect to any website, Firefox should provide direct help to the user as to the current major problem. I appreciate user ideas but Firefox should offer some help for major problems as the likely solutions can change over time. Hopefully if Firefox oversees user questions, someone at Firefox tech will at least respond to my question on this website or better yet contact me directly.

The problem may well be the update itself. The Firefox browser is working on my smartphone but not the desktop internet browser. I have some browser settings that I do not want to lose which a complete Firefox removal and reinstall would likely cause. Any suggestions from fellow Firefox users are appreciated and I look forward to them. Have other Firefox users experienced this major problem?

Thank you.

I wanted to open www.wattpad.com ,but firefox is not reaching the web i request u to resolve this problem as soon as possible
