I Was Looking For This OPERA15+ Information A Long Time Ago.
Almost All CHROME Clones Have Several Direct Commands, Or Extensions, For Relaunching The Browser When It Is Needed ( Like When The Browser Is Upgraded ), And Only 1 Click Away, But They Do Not Work With OPERA15+.
As Far As I Know, OPERA15+ Needs 3 Clicks, Which Includes Exploring A Settings Page.
A - Create A Bookmark With The Command ( X ):flags
B - Replace ( X ) With A Single Word: about, browser, chrome, opera
> Example: opera:flags
Explore The Flags Page That You Called, And It Will Work.
It Is An Indirect Way Of Relaunching The Browser, But It Is The Only One I Know.
Cheers.
