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 3.4.1:
- Support upcoming WebExtension version of Notification Sound
- Fix placeholders in translations
By upgrading this to this version, your data has been migrated, so it will persist past Firefox 57. There will be another update for Firefox 57, since this version will not run there.
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!
