Mac OS dictionary in Opera and Firefox?

Question

Opera

Good afternoon. Tell me how to make the standard three-finger tap work to call the dictionary in Opera or Firefox under Mac OS?
This is the only thing that keeps me on Safari so far.

Answer 1

There is a wonderful utility BetterTouchTool, which is also free, allows you to reassign tapas as you like for any program, set and bind the necessary tapas for Opera and Fox to the desired key combinations or actions.
