Note that the link contains "Sony Xperia Z3 Compact", "Android" and "Opera Mobile" - it is the adware which has access to your device, not necessarily the website.
You're a genius, horshack. That absolutely works! Brought back my scroll arrows. I'd disabled the animation options a while ago.
I've re-enabled all three: window animation scale, transition animation scale and animator duration scale. I noticed that the higher the duration selected, the longer the arrows stay on screen. 0.5x is a bit short but 1x seems about right. Shame animation has to be on though as I find things much quicker without. Nevertheless, I'm glad to have the arrows back.
... or simply use the website's favicon on the speed dial page.
I get a random and incoherent mix of favicons, the website's name from the url or the first letter of the websites name on my speed dial page. Very messy.
The power is in the option to choose. Good software provides comprehensive user options and choice... as well as doing what it's supposed to do properly!
