[Cialug] Firefox for paranoid people

[Matt Stanton]

I'm not sure if there is a difference between linux FF and windows FF as 
far as plugins are concerned (I think they are OS independent byte-code 
style plugins), but I have perspectives running just fine on Firefox 
3.6.3...  Their spot on the Firefox add-on site is pretty old, it seems, 
but if you follow the link to their homepage, you can get the 
perspectives version for 'Firefox 3' (and the source code, some info on 
making the perspectives network verify ssh targets, and all their 
research papers on the subject):

>>
>> Then I went into Preferences->Privacy and set Firefox to "Never remember history" and suggest "Nothing".  I also cleared my history that was created thus far.  In Preferences->Security, I told it to never remember passwords, block reported attack sites, web forgeries and add ons.  (By not remembering passwords, I render myself less vulnerable to risk from theft of my profile directories, but more vulnerable to keyloggers... it's a good tradeoff to me.)

>> cd ~/.mozilla/firefox
>> cp -a blahblah.default research
>> cp -a blahblah.default secure
>> cp -a blahblah.default webdev
>>
>> Then I edited profiles.ini and copied the four top lines of [Profile0] to new blocks of Profiles 1 through 3.  I edited the Name and Path to reflect each of my new profile directories (research, secure, webdev).  Then I edited the FIrefox launcher and appended "-ProfileManager" to the "run command".  This way, when I click on the little icon, Firefox will prompt me for the profile I want each time I launch it.

>> I then launched it and selected my "research" profile.
>>
>> Here, I went back into Preferences->Privacy and told it to go ahead and remember history and make suggestions (as when I'm researching things, I often forget where I found things and what I searched on.)  Then I installed the following add ons:
>>
>> * Add N Edit Cookies for cookie manipulations
>> * HackBar for SQL injection fun
>> * PassiveRecon for exactly what it sounds like
>> * RefControl for mangling HTTP headers
>>
>> Then I added the following search engines to the dropbox:
>>
>> * Offensive Security Exploit Database
>> * Security Focus Vulns Search
>> * Security Wire Search
>>
>> I'll probably add more as I play with it.  I'm still not used to using this feature to search the deep web.  (Wonder if one could be written to access our corporate wiki?)
>>
>>
>> Then it was time to restart Firefox and activate, set preferences, yada yada yada.
>>
>> After that, I restarted to access the "secure" profile.  Really, I should have named this one "paranoid".  I went into Preferences->Security and turned on ALL warning messages.  It's annoying to use now, but that's partly the point.
>>
>> I set StartPage to my initial home page, using the "Generate Custom URL" feature on the site.  Since I'm not storing any cookies at all, this is how it has to be done.  I removed all search engines and added IxQuick HTTPS, Startpage HTTPS and Scroogle SSL.   On the AddOn side, I added Force-TLS, though it really doesn't do all I'd like it to.
>>
>> Lastly, I installed the Orange Fox theme, which is ugly and garish, but since I wanted a visual reminder that I was in the paranoid profile, it was exactly what I wanted.
>>
>>
>> After another restart I entered the webdev side.  The fun new add ons here were:
>>
>> * Firebug for tracing DOM and CSS issues, which I don't do much anymore, but it's still nice to have.
>> * FlashGot for massive download fun on archive.org
>> * Greasemonkey for fixing stupid sites (and integrating with FlashGot to bypass trivial Javascript-implemented "security" checks)
>> * Live HTTP Headers for watching traffic in real time, when I don't want to launch a real proxy
>> * Web Developer for the same reason as Firebug
>>
>>
>> So, can any of you think of anything that I missed?
