Extensions do not load in Tor Browser 9.0 when directory path changes
Following upgrade to Tor Browser 9.0, extensions fail to load if Tor Browser is used as a portable application i.e. when launch directory path changes. Event occurs on Windows 10 1903 update with all extensions, including NoScript and EFF-HTTPS Everywhere. Disabling/Enabling extensions has no effect. Extensions can be re-added under new path; extension settings do not carry over, and extensions fail again upon subsequent path change.
Issue tested on separate Windows 10 device with 1903, extensions also fail to load. When path is changed back to original setting from before upgrade, extensions load normally again.
about:debugging displays the Extension ID for all previously installed extensions, but no other information is available. Issue cannot be recreated in Tor Browser 8.5.5.
