it throws error on console:
Uncaught ReferenceError: jQuery is not defined

It breaks some pages, by far I have found the inoreader browsing page. If you click the some menus or buttons which open some popups on the pages, it can't pop back. Additional error message if I enable this addon was below:

Uncaught ReferenceError: jQuery is not defined
https://www.inoreader.com/sinner.php# :1
sinner.php:1:445

Does what it says it does, but doesn't feature a whitelist nor blacklist, meaning I have to go into my addon settings to turn it off every time I want to use Google Docs. Annoying, but serviceable. Would be nice if I could also toggle different functions separately, like make it so I can select unselectable text without replacing site-specific right-click menus.

Real nice addon. But there are two destructive problems:

1. It disables secondary click (right click for most people) on sites like YouTube, and google drive and mega. Without right click, google drive and mega are completely unusable.

2. As a developer myself, I tend to write my own HTML and CSS, and every time I do that, and open my own app without jQuery, I get Uncaught ReferenceError: jQuery is not defined
file:///tmp/p.html:1
p.html:1:445

... so for any developers, that wrote 20 lines of HTML CSS will be surprised to see what's going on! The developer of this extension must be very noob because they haven't considered this small yet very important problem!!

So 2 stars but not 1 star because it gets the work done.
