Investigate exception in 81
# In 81, marionette.get_url() sometimes fails with: # `UnknownException: TypeError: browsingContext.currentWindowGlobal is null` # It happens when clicking "Always Prioritize Onions" in the doorhanger: # opens a new tab + refreshes the previous one, then when we close the new tab # and move to the old one, marionette.get_url() throws the error. # Until a proper fix, this workaround seems to work fine.
If there isn't a clear reason for this happening, maybe the solution should be #40006.
