I do not like it, it constantly overloads my cpu and has been giving other issues with my system. Used to use add-ons to limit resource use, by only white listing specific scripts, the alternatives and "updated" ones don't have the functionality. My computer has been hick-upping due to the cpu load

Quantum is the next Firefox 57 release and is currently Beta. You can install the current Firefox 56.0.1 release if you do not want to keep using the Beta version.

You need to install the full version of the current release.

Keep in mind that your profile might be getting corrupted if you revert to a previous version.
