If I'm using Firefox and filling out a big form (with lots of text to write), and for some reason I accidentally press F5 and all my text in the forms is lost, I can use e.g. HxD on Windows to retrieve the text, because they're still in memory. How can I do the same under Ubuntu?

You can browse through the virtual /proc/kcore file (the image of the RAM) and look for a string you typed. So for example (all as root)

strings /proc/kcore | grep unbelievable

will look for a string unbelievable

hd /proc/kcore | less

will give you a hex formatted output of all the RAM.

As a sidenote, I would recommend using the Lazarus FF/Chromium extension, which can save your bacon/forms and prevent these problems.
