Last week my opera started updating while I was using it and afterwards I lost all my customisation settings.
This was unfortunate, but I can live with it. What I find harder to deal with is that after the update, my Whatsapp extension and some others such as fb2mate or apknite has become so slow. Whatsapp shows text a full second after I've typed it and it takes 5 seconds to open up after I have closed the extension window (but it's still running in the background)
Does anyone have any tips on how to improve the Whatsapp extension speed?
