The best extension
Great extension but fails to work in page iframes :( yes the iframes are for the same domain it just doesnt attach the script or CSS to them
This is what we have been waiting for. A great app, simple and works great. Sr JS Devs don't require JS Validation ;)
I use (and love) it for many websites!! Thx
Bagus tapi tidak bisa menginject html :(
excelente, cumple con lo prometido
I wish there's a keyboard shortcut to delete a line of text in the editor
Could add a night mode theme to be perfect!
thanks dear for this awesome extension
