There was a bug in Open In New Tabs 1.1 which prevented Follower Checker to not work properly on some configurations. It has been fixed now.

You should get the new version in a few hours, but if you want to update manually (recommended!) here’s how to do it:

1. Click on the X icon > Manage Extension
2. Select Open In New Tabs
3. Click on Re-install / Manually Update this Extension
4. Refresh pages.

Thanks for using XKit, and sorry for any inconvenience.
