Very annoying issue. So simple for developers to allow a "remember this decision" option when accepting the error. This has been an issue for years, but it never gets solved.
Ultimately it may cause me to move on to a different browser because I administer several servers with self-signed certificates and I have to go through this multiple times a day. Firefox allows these decisions to be remembered but in a different issue, it go so slow for me I had to switch to Opera.
