H-ify ავტორი Master of Blinchiki

Upon loading this add-on, every Latin letter will be replaced by the letter H.
Lowercase letters are replaced with 'h' and the uppercase ones with 'H'.
This add-on works on every website EXCEPT google.com/search, as it entirely breaks the site for some reason and makes it unusable.
The goal is to turn every letter into the letter H without making a website completely unusable.
