Who still uses opera mini?
This is not in a any way an act of spite towards opera mini makers but to realistic, opera mini only renders people's site and make em inaccessible claiming its conserving data in the process. Other good and better browsers like UC browser and Google chrome respectively also have data conservation features which seemed more effective. Opera mini also preaches about ad blocking which other browsers also have. Using opera mini will only deprive you from good user interface and good features of the sites you're browsing on, that's my own opinion.
That is absolutely correct. Gone are the days when websites are simple HTML. Back in those days, Opera mini was a useful tool.
Now many websites are more like an app which makes Opera mini not very useful.
