It seems it doesn't support e10s but since e10s is disabled on my profile, I couldn't say if it still properly works despite that.

I know mozilla changes too frequently and it's pain in the as* for dev to maintain their add-on. I empathize with you. I hope it will be compliant with future firefox release. I love it.

Do you plan to update it?

This add-on is dependent on XUL/XPCOM which will no longer be available on e10s. e10s will only support the new WebExtension API. Regrettably, I have no plans to migrate to the new API for this extension.
