Yep, As i know, Most of Chrome extension works fine in Opera
So the extension author(s) officially say that the extension supports Opera? I don't see such extension in Opera's addons page so it seems to not be officially supported.
Not officially support. But i think you also know Opera have same layout engine, same dev tools....at least...Look's same.
I never see there have any special feature for Opera's dev tools, so... It they just use origin code of Chromium dev tools, this extension should work. or may i miss something like namespace...
