Short description of error
Whenever clicking any button or any menu item that opens a link in your browser, it takes abnormally long to actually open the link. Takes from a few short 1-2-3s to 5+ actual seconds.
Exact steps for others to reproduce the error
Click on any button or menu item that opens a link in your default browser.
It will first go unresponsive for a couple seconds, then it opens the link.
Based on default startup file. Also tested with removing prefs entirely. Doesn't help.
P.S. My default browser is Firefox
