[tor-commits] [tor-browser/tor-browser-80.0b2-10.0-1] Bug 14631: Improve profile access error messages.
commit a61ebc88d69d6f0299dac56b4d84e4088bff2abf
Author: Kathy Brade <brade@xxxxxxxxxxxxxxxxx>
Date: Tue Feb 24 13:50:23 2015 -0500
Bug 14631: Improve profile access error messages.
Instead of always reporting that the profile is locked, display specific
messages for "access denied" and "read-only file system".
To allow for localization, get profile-related error strings from Torbutton.
Use app display name ("Tor Browser") in profile-related error alerts.
