Hi!
This is not a plugin idea, but rather a browser extension... anyway:
I use
this add-on on waterfox classic. (
this one works for me only when called from context menu, but not from the toolbar button, so I prefer the former)
Those add-ons enable me to have a Goldendict toolbar button and a shortcut key that allow me to select text on a webpage and have the dictionary program open and look it up seamlessly.
Analogously, it would be awesome if one could select text on a webpage and have Calibre
open a FTS search for the selected text.
As Goldendict is also a QT based program, I suspect this might be feasible...
I've tried adding Calibre to the newer External Application add-on, but I couldn't get the selected text to be passed to the Calibre search bar either.
