I'm using Firefox 70 and it's not working.

Since last update (I think Windows10/Firefox ) highlight is not visible.

Doesn't work the majority of the time. Trash.

I do not have a quick button to enable / disable add-on.

Tons of time has been saved for me.

Basic functionality works well. It copies text that you select.
The problem with this (and every other auto-copy webextension I've found) is recognizing which fields *not* to copy from. For example, this extension doesn't copy from basic text fields, which is good. But it does copy from Gmail's compose field, which is bad.
A simple mitigation for this would be a user-manageable site blacklist. Alas, this extension does not have that, or any options at all.
My search for an auto-copy extension that really works right must continue ...

Be AWARE, this is SPAM addon!

Great thing but no function with FF 60.0.2. I loved this addon always before.
I also use ScrollAnywhere with right mouse button. Perhaps it is not compatible?

Doesn't work on sites that have content inside frames :(

Does not work with FF 60.

С этим аддоном криво работают гугл-таблицы (не работает копипаст), не работает контекстное меню.
Отключил, ищу замену.

gd

It does what it says on the tin.

5 STARS!!!!

This is the only autocopy addon I've tried that will copy text, and let you highlight another word so you can replace it with the first copied word.

Brilliantly done, and minimally designed. Thank You!
