Just like mgkrupa said [(I heard that Mozilla is working on finally giving Firefox its own tab manager, so we'll see if tab manager plugins become unnecessary)].
This is with all my love and I hope the message is understood <3
I hope that all extensions like these are needed again and firefox adopts them natively, I find this extension perfect, it has magnificent synchronization, I can be between my PCs without having to look for another one or search for it in an endless list of pages/History, the I can separate it into different lists and it is simply magnificent, the only pity is that it is not available on the phone through the screen interface, as I see it, the extension does not consume cpu or memory in a strange way, hopefully the rumor that I read is true and firefox take all window managers and unify them, hopefully this extension will work natively :)

Translated from Spanish to English by Google translator, any inconsistency is due to that
