CloseReview for Custom Buttons by ferdie ferdsen
Rated 5 out of 5 stars
I use some buttons since years. (Clear SearchBar, URL-Tools, Easy Reader (1-click) and some others...)
Now, with FF 43 I feel no difference.
FF is as slow as usual ;-) (Have >40 addons installed)
The buttons, I use work good, since years.
I hope, they will work a lot of years along.
