I'm trying to create a Ubuntu Firefox Kiosk but I cannot disable the resource:///, about:config back doors. Can I make it so a clever user cannot access this?


I'm attempting to make a Ubuntu 10.10 Firefox Kiosk for public use and I have everything set except for the built in back doors that Firefox has. I was able to block "file:///" and "chrome:" with a proxy filter but "about:config" and "resource:///" still gain access.

Most of the people that will use this Kiosk won't have a clue how to access these but I need to prevent a few clever people from messing with settings. Is there a way to disable or block these "back doors"?

Any help would be appreciated. Thanks!

Hi Es44pop,

I don't have any personal experience of trying this but I have found a few likely looking options for you. I hope one of them will help:






Let me know if none of this works and I'll try to point another volunteer, who may have more experience, to this thread.

You would probably need to run Firefox in a virtual machine to disable browsing to real folders on your computer. You can't do that with locking prefs (you can't disable protocols).
