Wait, don't just close this tab. If you don't want to see the changes when the add-on updates, just uncheck the "Open a tab with update info after an update" setting.
Changes in 2.9.3:
- Fixed an error where the extension would stop working when certain tabs are opened.
This version still can't do this nice thing!
Enjoy the extension?
Since you've already had the extension installed you seem to like the extension. It would be great if you would recommend the extension to your friends or watchers! Leaving a review on AMO is also a great way to tell me what you like and what you dislike!
