I don't think this will be concerning for Tor Browser; aside from
needing to set the appropriate bits for the bundled extensions.

This is an FYI so you don't get surprised in the near future.
The extensions API includes support for an "incognito" entry in the
extension manifest where an extension may opt-out of running in private
browsing windows. Chrome has since made that the default, and requires
an opt-in by the user to run an extension in private browsing. We're
playing a bit of followup on this, since we bypassed the feature during
the crazy ramp-up for webextensions.
The intention is to land this for 66, and a large chunk of it landed the
other day. Extensions currently cannot make use of what has landed
(though tests can and do). Extensions will continue to work as they
previously did until we pref the feature on.
The next part to land will be additional UI in about:addons that
allows the user to enable an extension for private browsing. A pref
(off for now) will be introduced to enable this. At that point, you
will be able to play with it, however there is more work to be done at
the webextension API level. The pref will not be turned on until all
necessary API modifications are completed.
Assuming that everything goes according to plan, you will see this
pref'd on during the 66 nightly cycle. At that point, all of your
extensions, excluding system extensions, will stop working in private
browsing until you enable those you want to work there.
If you are curious you can look through the meta bug. If you have
questions, please feel free to reach out to me, mixedpuppy, on
#webextensions irc channel or #add-ons on slack.
