A few weeks ago, Francis wrote a piece here about the (formerly) secret developer menu accessible via URL, Developer menu is a great finding but is not the only one URL hack available. These are some of the URL “hacks” I use:
Selections performed under “identity 1” won’t impact on the tab session “identity 2”, alternatively you could share selections in different browsers by using the same identity in each one of them.
Adding /ttl/ and a number representing seconds will override the settings of session-expiry time in the server, setting it up to the number specified in seconds. For example, adding 1800 will set the expiration time for the session to 30 minutes.
