I'm going to talk exclusively about the browser on pc
what the effing eff
seriously
why each user have to come here and ask to be OP'ed ?
since opera took it's big turn to looks like (or more like "be like") chrome it's just an abomination for users ...
no more options
no more customisation
and now : no more synch
looks like at opera you don't even know how to make a good reply box 
so @annelisek said :
please note that it is in an experimental stage.
then :
why the hell there's no informations about this experimental stage on, FOR EXAMPLE, this page : https://link.opera.com
(this page is useless btw because in the video it's not the last version of opera ...)
or :
Why the effing hell this link synch that doesn't work is in production and available for users ?
thank you for reading me
