CRX Installer автор FoxRefire

I recommend using this extension with the following supported browsers.
It will work with the regular version of Firefox, but additional steps are required.
Supported browsers
* Zen browser (Recommended)
* Firefox Nightly
* Firefox Developer Edition
* Librewolf

Except for Zen, value of xpinstall.signatures.required have to set false in about:config.

Caution
Installing untrusted extensions can pose a serious security risk.
Developer will not responsible for any damage caused by the user's actions.
Always act prudently and at your own risk.
