so, how can I export the WHOLE 'about:config' from firefox into plain text file. Screenshot would be good enough although text file is preferred.

My favorite firefox extention sceengrab cannot handle it.

Please note that I am on Mac and I cannot find 'prefs.js' file.

Assuming you want your preferences on another computer you can just export the prefs.js file. I'll keep looking in case there is a specific reason you need a text file, although technically a .js is a text file of sorts. This should clue you in as to where prefs.js is on a Mac.

we needed to send it so somebody else can compare it. So it's not 'simple' export/import thing... thank you for the help – Radek Jul 19 '10 at 5:45

I have create an autoit script to automatic export the configuration content and compare with python. Check the article and scripts from my blog
