@acerswap This seems to be a bug with browser.js
, which is a script that runs in the browser to patch things out of various websites (think annoying thing's like "Why use Opera, when you can use X", "Your browser isn't supported, use X instead").
In the latest version it seems to be bugged and puts the version number on every page (including nested ones! yuck) instead of only on it's own information page at opera://browserjs
/ chrome://browserjs
.
For now, until it gets fixed, you'll need to open a page to opera://browserjs
and then click "disable browser.js ... for this session". Unfortunately it'll come back whenever you reopen the browser until it gets fixed.
