Hello, today I suddenly had the following problem: whenever I try to check on add-on updates, the manager opens multiple occurrences of Firefox and multiple tabs, most of which seem to point to
https://versioncheck.addons.thunderbird.net/
The Firefox pages only show the icons of each of my add-ons (half of which are disabled currently, as not Version 60-worthy).
Is there any way of correcting this glitch?
I also cannot reconnect Lightning to Google Calendar, I keep getting the error message “Invalid_request” once I have entered my gmail address.
I’d be grateful for some help.
Thanks
