Multiprocess tabs always crash, as first reported by the issue mentioned
below. It is now consistently reproducible both on NixOS and non-NixOS
for me, so I've decided to add a toggle to conveniently disable
multiprocess support as a work-around.
Closes https://github.com/NixOS/nixpkgs/issues/27759 but does
not really fix the underlying problem ...
(cherry picked from commit 69e3817eb6)
These changes reduce file accesses outside TBB_HOME or the Nix store, as
determined by running under strace -e access,open,stat.

This reverts commit 0a944b345e, reversing
changes made to 61733ed6cc.
I dislike these massive stdenv changes with unclear motivation,
especially when they involve gratuitous mass renames like NIX_CC ->
NIX_BINUTILS. The previous such rename (NIX_GCC -> NIX_CC) caused
months of pain, so let's not do that again.
(cherry picked from commit ec8d41f08c)
The `extraPrefs` parameter is injected verbatim into the mozilla.cfg
file.
Note that the syntax is a superset of the usual prefs.js syntax. The
following procedures are of particular interest:
pref() to set a preference as if it had been toggled in about:config
defaultPref() to set the *default* value of a preference
lockPref() to set a preference & prevent further modification
clearPref() to reset a preference to its default state
Example:
```nix
tor-browser-bundle-bin.override {
extraPrefs = ''
// Increase default security level
pref("extensions.torbutton.security_slider", 2);
'';
}
```
