Many about:config entries in Tor Browser that were presumably changed for security reasons appear as modified, and can be reverted back to their ‘defaults’, which I assume sets them to what the default would be in Firefox, not Tor Browser.
Would it be good for Tor Browser to come with a different default configuration, so that people don’t end up in a state where they can’t revert their about:config changes back to what they should be in Tor Browser because it assumes the wrong defaults?
