Kong Add-on Firefox

Kong Add-on

By: Forth
Kong Add-on adds some features to Kongregate, including a blocker of bot messages, a dark mode, a brighness adjustment, and more.

Features & Capabilities

Kong add-on will add a button to the top left of your screen for enabling and disabling the dark mode on website. Furthermore, some visual effects have been modified or corrected.

A feature has been added to adjust the brightness of games to make them darker or brighter.

Cinematic mode improved. It adds a dark background and prevents any mouse scrolling while you’re playing to keep your game in the center of the window. No more accidental scrolling while playing!

Chat updated!

To begin, the bots message blocker is able to block some words to not display some message those of bots, if they contain their website link. Then, a feature to change the text size has been added. You can now reduce or increase the text size. Really useful when you adapt the game to your screen. You can also enlarge your chat by hiding online players list, or just hide your chat completely if you only want to see your game. Furthermore, when a player posts a new message in the chat, you will be notified by a ping. You can adjust the volume higher, lower or outright mute it.

The Kongregate add-on is using cookies to store your preferences. In total, 4 cookies are used for ping volume, game brightness, dark mode on/off and text size.

By default all quick links like rating, playlist button etc. are hidden to gain some space for new features.

User Reviews

I just installed, after swapping through half a dozen zoom exts, because some game windows are so small that its hard to play without zooming and i was hoping for a way to stretch the game automatically. first impressions, its amazing! the one and only thing i noticed worth complaining about is the scroll lock: when you lock the window, it snaps to the top, and could cut off part of a larger game window (and does- Mergest Kingdom). i think the lock should be fixed or an option added to lock on the current position, not the top of the page.

Is Kong Add-on Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Kong Add-on requires very minimum permissions.
