Firefox Community Forum

Hello,

Hopefully this is something that can get answered quickly. These past few days I have not been able to use FireFox on my laptop.

It doesn't seem to be a wifi connection issue because other browsers work and other devices are connected just fine.

I also tried opening FireFox in the "troubleshoot" mode, but I am still receiving the same errors. I would appreciate any help I can get on this issue.

Below is a screenshot of the error I keep receiving.

Thanks,

For two days I have been unable to access the internet using my default Mozilla Firefox browser. I have used Mozilla as my default browser for many years with no problems, but have had to use alternative browsers not only to access my emails on Outlook, as well as other nominal sites, but even to sign into my Mozilla account, I had to use Microsoft Edge browser. I have made no changes to my settings or internet security. Please advise. Thankyou

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.

Long story here:

A few weeks ago, I lost internet connectivity on my desktop PC at work running Windows 11. I checked Firefox, Edge & Chrome but couldn't access any site. It took a few hours and a lot of updating Windows, rebooting each time the internet kicked out, but I got it to work again.

Fast forward to this past Monday the 29th when the issue happened again. Within roughly a minute, the internet just died on my desktop again. I grabbed my work laptop, also running Windows 11: same issue happened within 60 seconds. I checked Firefox on a desktop running Windows 10 - had no issues at all.

Today, I installed Firefox on another laptop (the same model at the other one) running Windows 11. As soon as it synced my account, the internet stopped working. I though it may be the Sync option, so I reinstalled Firefox on my laptop but did not log in to Sync - the same issue: dead internet within 30 seconds now.

I have:

• Run anti-virus
• Run network diagnostics and reset
• Rebooted a multitude of times
• Uninstalled, reinstalled at least twice
• Run troubleshooting in Firefox (which I cannot attach the logs due to it being uninstalled right now)
• Checked to make sure my modem/routers are working right (no one else in the building has this issue and we all use Firefox, but none are synced to my account)
• I even asked my company's tech team (who are mostly software developers) and they said No, sorry, we don't help with that (wonderful right?)

I've attached a screenshot of the OG machine's information. Not sure if it will help at all, but it's worth a shot.

I keep getting the same DNS error for pages that I have been to 100s of times before. Why is this happening now? I'm guessing it's because of a recent update, but can't imagine why Firefox has an issue with Rebel Sport all of a sudden.

Have attached a copy of the error page. Hoping someone can explain why this is happening and how to get rid of it.

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.

Dear Sir/Madam I am unable to reach Jiohotstar website since last three days. The same site is accessible through Microsoft Edge and Chrome browsers. I also tried through Firefox browser on a different machine but could not succeed. I have cleared all the cookies and cache as well but it was of no use. Firefox is running with the latest version. There seems to be a glitch in the browser somewhere. Pankaj Mittal Mail : pankajmittal105@gmail.com

I just purchased a year subscription for the Mozilla VPN. I want to be able to verify that the FireFox browser I'm using is accessing the web via the VPN. How do I verify that? I don't see any icon indicated that it's a VPN connection.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

I have a secure private network on my CPU. Why does Firefox not allow my secure websites to remember this browser? The website gives me the option "Recognize this browser." I check that box. But it is a vicious cycle. There is such a thing as too much protection. This makes it time consuming to access my accounts, requiring a cell phone and code to access accounts. Please advise.
