Cannot start Brave or Thunderbird, but Opera is OK

General Help

Hi,
I've just installed Zorin 18.1 Core as dual boot on a Surface laptop 3. Everything was fine until I installed the Surface-specific patches to enable the touch screen. Touch screen now works, but Brave browser will not even start (just a busy cursor for a few seconds). Uninstall/Reinstall does not help.

Tried installing Thunderbird and the same thing happens - no response.

I managed to get online by installing Opera from the Zorin software store. Opera works perfectly.

How did I break Brave?

Thanks for any help.

Steve

Welcome to the Forum!

Can You start them over the Terminal please? So, You get an Output in the Terminal. That could be helpful.

When Brave is installed as .deb/APT Package, simply type in Terminal brave-browser to start it.

Thank you for the rapid response!

I tried the Terminal start, as you suggested, and I discovered why I had the problem. It is due to the fact that I changed the Device Name in Settings>System>About and the instance of Brave was locked to that old name (Terminal output below).

The obvious question is: how do I unlock the profile so that Brave (or anything else) is not affected if I change the device name?

Thanks.
P.S. I mistakenly mentioned Thunderbird in my original question - I should have said Firefox. I presume the problem occurred because Brave shares code with Firefox.

Take a look at this thread, that may help for brave-browser:

Hmm ... You could try it for now with a Reinstall:

sudo apt reinstall brave-browser

Or You could try to delete the Profile and create a new one.
