RE: Extensions for Opera 12??
First off, when I go to the page for the extensions, or when I choose one I already have installed (Ghostery), at the top I get a banner stating;
"These extensions and wallpapers are made for the Opera browser."
The button "Add to Opera" is grayed out. If I click on it I get "Opera Required"
I unfortunately uninstalled a ad blocker that was causing issues with a few sites that I couldn't figure out how to selectively ignore blocking on those sites. BOTH of these I just installed to a fresh install of Opera 12 less than a couple of months ago.
There were many that wouldn't work in this version, but others that would as it's been since 2-3 years ago. This is really BS! All the crap they seem to have for their 'toy idiot phone' designed, so-called browser looks like some childish grade school cartoons.
