Firefox browsing failure after upgrade to 126.0 (64-bit)

more options

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

Thank you for your report. Did you un-pin and re-pin the shortcut, or did you have to make some kind of edits to it? If you could detail the steps, that would be helpful.

I unpinned the Firefox shortcut from the task bar and expected it to be somewhere on my desktop. It wasn't so I pinned a new shortcut from the Firefox executable back to the task bar.

Thanks. I wonder why the old one stopped working? Strange!

I wondered if the old version had a different executable name or was installed in a different folder.

No, on further reflection, that could not be it because the executable was launched.

IDK.
