How do I set default web browser?

[BartTheBoxer]

When I click on the "Remote" icon, I get an error message:  "Unable to open your web browser to 'git@github.com:xxx', do you have a default web browser set?"

Where "xxx" is the name of a remote repository on github.com (which does exist).

How do I get past this?

This problem has nothing to do with the default browser.  When you click on the Remote-Globe icon it will attempt to redirect you to the remote server that is defined in the Repository Settings Optional extended integration window.

To reach this window click the Repository pull-down Menu, Select Repository Settings.. and you will see the Repository Settings Popup menu.  From the Remotes Tab select the "origin" line that contains the path to the remote depository.  Then click on edit, and the "Remote Details" popup window should appear. 

From the "Remote Details" popup window you can select the public Bitbucket, GitHub, Unknown, or Bitbucket-Server as your Host Type.  If you select "Bitbucket-Server" you will be able to enter the Host Root URL of your remote server under "Legacy Account Settings", aka "default brower"

Once this is done, you should be able to click on the Remote-Globe icon and start a browser view of the remote repository.  It may be necessary to enter your host's username and password too.
