Hi, could you please advise how to prevent users from changing basically all the Firefox options, especially
-Search engines
-Privacy settings
-Security
-Network
-toolbar buttons?
Also how to prevent users from creating bookmarks (or how to delete bookmarks each time Firefox starts) and how to start Firefox with bookmarks/history sidebar hidden by default (if opened in previous session)?
It's for a public PC with Windows 10 x64, where kiosk mode is not fully suitable. Currently, there's a not-very-elegant script which restores the whole profile folder on every Firefox start, but I hope it's only temporary solution.
I've managed to block several options with GPO policies, such as homepage, addons and about:config, but it's not enough.
 
Thank you
 
Rod

We don't have plans to offer that level of locking down of Firefox. A few of them are on our list, but not all.

You might take a look at


or


Which provide some middle ground between a bare bones kiosk and full browser.

Back around 2003, when Firefox was called Firebird, I did some major surgery on the UI's XUL code to make a specially tailored kiosk-like version which ran on a dedicated Linux computer with a minimal window manager (MWM), but no "desktop". (Running Linux with no desktop made it hard for users to cause any problems that couldn't be fixed by a simple reboot.)

The purpose was to provide a museum exhibit. It had no Internet access, but could only display the contents of onboard HTML files -- and play MIDI of historical music. Many other operations, like Open, Save, Print, New, Preferences and Quit were removed, and every page had a 5 minute inactivity timer (via JavaScript) that went back to the home page (which was animated).

This was pretty straightforward to do in XUL (I did it in my "spare time"). I doubt if any *custom* lockdown like that is practical now, given that Firefox has been "improved" by the complete removal of XUL.

You can still do all the same stuff with XHTML. I do these kinds of customizations all the time.

And it works exactly the same.
