Firefox's add-ons where showed on the right, next to address bars and some where pinned to the hidden menu.
After today's FF 63 update all extensions are gone and there is no hidden access menu icon. On add-ons page all are there but in practice they don't work so I have no access to password manager and others.
Here is how the hidden access menu icon should look like:
The fact that in "Adjust" page is grayed out means that there are no add-ons to show, so when we go to usual browser window/tab I see only this:
So once again, add-ons icons are not showing and they are also not working, although they are marked as tuned on on the add-ons page.
