So, this has been going on for a while in multiple devices.

If for some reason the network that I'm connected to loses connection to the internet and I connect to another network that has internet access Firefox fails to recognize that there is internet access from another network. The only way to get Firefox back online is to close it and open it again, losing any work that was being carried out.

This happens with multiple devices on different networks

¿how do you get Firefox to understand that there is internet access from another network? (like when switching from wifi to a cabled connection)

"I'm experiencing an issue where Firefox shows a 'Trouble finding site' error every time I visit a new website. However, when I refresh the page, the site loads correctly. This issue persists across multiple websites and requires a refresh every time I navigate to a new page. Has anyone else encountered this problem? I'd appreciate any help in resolving this issue."

below example shows: visited site -> error -> refreshed -> now works

this has been happening for years now, every time i open a link or a website, 9/10 times it gives me the

Hmm. We’re having trouble finding that site.

We can’t connect to the server at (literally any website).

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

and i always assumed it was a laptop issue so even when i got a new laptop a few months ago, since day 1 it has done the same thing with any website, and i have to refresh so many times before it decides to load in finally.

Hi Mozilla Team,

I'm currently using Firefox version 142.0 (64-bit) and I'm having trouble setting up a proxy. I've tried configuring it through the usual settings under Settings > General > Network Settings > Settings..., but unable to configure the Proxy in Firefox 142.0 (64-bit), but no luck.

Is there a known issue with proxy configuration in this version? Are there any new settings or changes I should be aware of that might affect proxy setup?

Thanks in advance for your help!

Could someone clarify where Firefox stores the list of domains that bypass the proxy (the ‘No Proxy for’ list)?

After refreshing the browser this information is gone from settings.

Thank you!

I'm experience trouble with firefox loading pages. It seems that some pages (about 1 in 10) will not load first try. Instead it results in either a "unable to connect", "Hmmm... Can't reach this page" or simply a blank page. I have not noticed any pattern in the pages on which this occurs and they all display correctly after a refresh. This problem only occurs on firefox. I have already tried disabling the proxy without any success. I'm looking for any suggestions for solving/diagnosing this issue.

System info: Firefox 142.0.1 Fedora 42 Linux kernel 6.16.3-200.fc42.x86_64

With the most recent updates of Firefox with secure server substitution, I often open the Firefox browser for windows and cannot even reach an initial page because reaching the secure DNS substitute servers (Cloudfare) is failing. The NextDNS server also does not work. I love this security but it appears something is wrong. I have long been using Cloudfare as my listed DNS sever on my router for the entire home LAN, but now it is not connecting by that or by Firefox (and Waterfox) - and this includes using Google and a few other major DNS alternatives , but the Chrome browser, I keep as a backup, works. Moreover, I have had to swap my default DNS on my router and in windows to be my local Spectrum (Charter) DNS servers 71.10.216.1 & 71.10.216.2. They always work when I turn off all Firefox securre browsing settings for DNS and HTTPS. I WANT THOSE PROTECTIONS FROM FIREFOX, BUT I DO NOT KNOW HOW TO MAKE THIS WORK OTHER THAN TURNING ALL SECURITY OFF!!

Hi. I've been having trouble with Firefox.

When I enter a certain website (https://app.helpwise.io/) using my PC, after a few minutes my internet connection gets disabled. When I try to run 'Diagnose Network Problems' in Win11, no issues.

First time this happened, a restart fixed the problem. Second time, a DNS flush fixed it. But after that, those solutions don't work anymore.

I initially thought it was that website (which I use for work) but I tried running that website on my Android phone using Firefox as well and I did not have any connectivity issues.

So, I tried running the website in Chrome - no issues. I did work side by side with Firefox opened as all my bookmarks for work are there, and eventually after a few hours my internet was disconnected again - even though https://app.helpwise.io/ was not opened in Firefox.

I have tried refreshing Firefox, then disabling all extensions and running https://app.helpwise.io/ and still it immediately disabled my internet.

There are some times that it even turned OFF my Avast anti-virus.

I have tried running Avast and Malwarebytes and no virus or malware was detected.

I still want to use Firefox and I'm now thinking of formatting my computer. But when I run Firefox again after formatting, I may have the same issue.

Can anyone help?

Until yesterday I was able to get into the Internet from my windows 11Pro pc. Suddenly I am unable to sign into the Internet using Firefox. It is saying the server name is not valid and the password is incorrect.

Trying to log in to Starlink and get a message "Fastly error: Misdirected Request (E2815). If you are the owner of the domain, please ensure the DNS settings are correct. Details: cache-pdk-kpdk1780113-PDK"
