I will have to deactivate this plugin until this is fixed. The '@' char is required everywhere, now i can't even enter my e-mail adress because this dict quick search toolbar pops up when pressing ALT+Q.
@Follow Up answer Sorry, i meant Alt Gr + Q. It happened on a Windows 7 Prof System while trying to comment to a Youtube comment. To test it again, i reactivated the plugin and i think i now narrowed the problem down. It seems to be, that my keyboard layout was accidently set to the English layout (EN) during that session (i have that windows language keyboard layout icon in the lower right corner) and i didn't noticed that. When the layout is set to English on the software side in Win 7 pressing Alt Gr + Q will result in this pop-up of the dict search bar. If i set it back to DE layout in the lower right corner, everything works fine again. So probably my fault. I don't know if its possible to make the plugin ignore the key combination of Alt Gr + Q if the layout is accidentally set to English layout but it would be a good thing in my opinion. I will give the plugin now 5 stars. Thanks for your answer.
Thanks for the report, but that has never been the case for me. On Windows and Linux, Alt Gr + Q is used for @. Not Alt + Q. Alternatively, Ctrl + Alt + Q can be used, which also does not trigger the add-on. I've researched Mac, but they seem to use a completely different combination for the @.
Could you give some insight into what system uses this shortcut for the @? (It's not the keyboard layout, as I'm using the german keyboard layout as well)
Sadly, there is no way to change this from firefox. chrome would allow to edit those shortcuts. But I could make this different per OS. The only other way would be to use a different shortcut or to not have a shortcut. Let me know if you have suggestions.
