Script started stopping while Web pages are being loaded. Had to disable. Otherwise was working fine

As a long time user I'm very disappointed. I switched to this after no script went on hiatus and it was perfect, almost every functionality I could want in a script blocker. As updates continued ublock started to break and lose functionality to where it is now, my only options being on or off. I've stopped using ublock and gone back to noscript now that it wants me to choose between breaking a site and having no protections. Unacceptable.

Update: Repeat again: No interest to read technical. from my view of point as an user I see the addon fails to work on websites in one browser and works perfectly in others.
So it is the work of technical specialist (the addon creator) among others technical specialists (browser computer programmers).
Please do not reply just as to reply and make some one the victim. Just solve the technical problem on your side.
Thank you and I hope you will be more carefully to read user review because most users are professional not in your area.

Mix together two programs functionalities leads to wrong way working tool.
I tried to send email to developer but got infinite sign up..sign up . I am just user one of most people whom programmers create software. No interest to read technical. Please check this link it works perfectly in Chrome and broken in Firefox (no flyer to see), Chrome 84 /Firefox 68. Windows 64 English. ublock installed by default only, no any other addons/extensions.
