Describe the issue

When I try to log into my email through Chrome, it takes a very long time to open the inbox, and sometimes I can't log in at all and have to try again. Additionally, the address book is incredibly slow; it takes about a minute for the search window to open after clicking on the address book icon. I've tried the same actions in Firefox, and I don't experience any slowness issues.

1.5 is in low maintenance mode. You'll have to update. Also I see the same refresh request could take a long time, but also short time. I doubt this is Roundcube issue.
