Rated 5 out of 5 stars

Using ver 3.5
The "New window" only appears for a moment, when I click on the toolbar button. "Popup window" appears fine.
As I remember, previously there was no such problem.
From the right click context menu on a selected text works fine.

This review is for a previous version of the add-on (3.5).  This user has a previous review of this add-on.

Could you give me more details?
What settings do you use?
If I can reproduce it, I can fix it.
I did released 3.5 yesterday but I've changed only Google Translate related code to fix problem with the consent page Google shows for some users.
