 Someone in #tor said all of the extensions in their tor browser instance
 stopped working after the upgrade to 9.0. They had non-standard extensions
 installed (so I assume this is part of the cause). When they go to
 about:debugging, they see the below warnings:

 {{{
 Reading manifest: Error processing hidden: An unexpected property was
 found in the WebExtension manifest
 }}}
 {{{
 Reading manifest: Error processing
 chrome_settings_overrides.search_provider.search_url_post_params:
 Unsupported on Firefox at this time
 }}}

 I do not see these warnings, but apparently Firefox emitted them for every
 extension (including noscript and https-e). The about:debugging UI
 [https://gitweb.torproject.org/tor-
 browser.git/tree/devtools/client/aboutdebugging/components/addons/Target.js?h
 =tor-browser-68.2.0esr-9.0-1#n135 shows] these messages between the
 extension name and the "Extension ID" lines.

 I don't know if we'll be able to reproduce this, but it'll be good to know
 if more people are having this problem.
