If we are treating this like an emergency, imagine if you were a resident of the flooding in Derna, what they would do if they saw the Exxon oil executives dining on the side of a posh cafe in their suits and tie saying the death of everyone in your neighbourhood is just business?
I would very much advocate for beating them up.
Alternatively, you could create a profile, for example name your profile
a1111
. To summon it runfirefox -p a1111
then change the options to always clear the cache, never store cookies, never keep a history, and you have effectively created a private browsing tab.Or better yet, you have a completely separate profile just for A1111 that will not interfere with your regular browsing.
It should be fairly easy to find the line to launch a browser window in the config then to launch the profile you just created.
