Windows 10: Browsers Works for Some Users

The browsers connect to internet according to the Windows Account. I have three non-administrative accounts on my Windows 10 Pro (version 1903, OS build 18362.535) computer that I will refer to as Pu, Org, and Ma. Currently Firefox cannot connect to the internet in any of them. Opera can connect in both Org and Ma accounts but not the Pu account. I have used Firefox and Opera without any issues for the past few months. I have not had any connectivity issues with Edge or Chrome.


CHRONOLOGY

1. Late last week Firefox and Opera stopped connecting from either Pu or Org while Chrome and Edge could.
2. Removing Firefox and Opera from the list of allowed programs in Zone Alarm, cold booting and adding them to Zone Alarm did not work.
3. I upgrade Opera from 65.0.3467.62 to 65.0.3467.72
4. I executed netsh winsock reset and netsh int ip reset. As a result Opera can connect to the internet from Ma.
5. After uninstalling Adobe Flash Player Opera was able to connect from Ma.
6. I updated the Zone Alarm security software, removed firefox.exe 51.0.1, crashreporter.exe 54.0.1, and pingsender.exe 54.0.1 from its Application Control list and added these three executables back to the list (The version numbers of all of the executables changed to 71.0 when they were added to the application list). I still get the "Unable to connect Firefox can’t establish a connection to the server at ….".

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.

 

Unable to set default browser

• Does this issue happens while you try to set other browser as default too or is it specific to specific browser?

Any browser.

Already did the steps you suggested. It's some kind of bug where it's impossible to set a default browser at all.

I heard elsewhere from one other user that it seems to be a problem with upgrading to 10 on the SP3. Sounds very specifc.

The tutorials provided are just a list of troubleshooting steps. Use only the steps which apply to you.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.
