Comment:

 `bug_32618` (https://gitweb.torproject.org/user/gk/tor-
 browser.git/log/?h=bug_32618) has the backports. I did not build the
 changes yet but I looked at possible `parseFromString()` calls that might
 still be problematic AND on esr68 while not being present anymore when the
 patches landed on Mozilla's branches. We are good here, though.

 I also double-checked that the patches for those two bugs are the only
 ones we need to backport:

 Bug 1585769 is relevant here but the picture-in-picture video feature is
 only enabled in Windows nightlies if the code is esr68, so I think we can
 avoid backporting that fix.
 Bug 1585588 is not affecting us as we don't ship that extension and it
 should be fixed by bug 1590526 anyway (which fixed bug 1576508 as well).
