Features of “JavaScript Toggle On and Off (WebExtension)” is enough good now and works smoothly for people who like switching enable/disable javascript quickly on Firefox 55.0.3. Specialty, Whitelist is really useful functions.

Would it also get “Blacklist” function to make more convenience in the future? With Blacklist people could browser with javascript execute on normal site, but auto disables javascript execution on that appointed page which has bothering javascript function.
