Open web browser with absolute path

On macOS, web browsers are opened via popen calling osascript. However,
if a user has a colliding osascript executable earlier in their PATH,
this may fail or cause unwanted behaviour.

Depending on one's environment or level of paranoia, this may be considered a security vulnerability.
(cherry picked from commit a0c57a8)
