Rated 3 out of 5 stars

IH caused a major problem in version 2.8 for those who also use the popular TabMix Plus add-on.

This problem was acknowledged and repaired in version 2.9. But the update to version 2.9.1 brought back the problems from v 2.8.

Again, the first opened tab will no longer close and the page load on the first tab never seems to complete.

I sent an email to IH 3 days ago but have yet to receive a reply in return.

This review is for a previous version of the add-on (2.9.1). 

This has been fixed

Version 3.0 resolves this issue.
