We don't implement FF's new add-ons manager page and this causes some problems (i.e. Menu button on top of search bar instead of previously being beside it, missing nav buttons, etc.)
Proposed solution
Revert commits 21c8262cf2b80d0e25945a4ec1116dce619f9b9e and 7707a7401c416124fefb824ffed0fe362a9a0f7b
