Please correct this bug and let us use it in FF57+ so we have an alternatives for TAB GROUPS extension

Edit: info for the developer, I have 500+ opened tab with FF57, and tab groups plugin disabled after ugrading from previous FF version, I can only see one groups, but other tabs are opened and hidden.

Thanks, for your reply, I know there is a firefox bug, I give you 5 stars waiting the bugfix from mozilla.
