Tab Behaviour Changed with Most Recent Update

What happened?

Waterfox updated to 6.0.13 recently and now the "Focus On Left Tab After Closing" no longer opens the left tab when one is closed. It seems to have defaulted to "last used" I think. I don't use the new tab side bar feature. Is it possible a setting has changed with the updates to this new feature?

Reproducible?

• [ ] I have checked that this issue cannot be reproduced on Mozilla Firefox.

Ahhh I see what has happened. The recent update reset all my about:config customisations. Perhaps some warning next time? Or better yet give us an option in settings to control tab behaviour.
