addon to Stop Scripts Which Are Running on the open tab?

more options

There are web pages where a "spinner" never stops. I have NoScript, so its probably blocking execution as I desire. But some pages never stop trying, and it overheats my computer -- this can be happening on tabs that are not "on top" and I have no way of FINDING the problem.

In 2015 there existed an addon that would allow me to stop scripts on the open tab: https://www.ghacks.net/2015/01/15/disallow-scripts-temporarily-on-web-pages-in-firefox/

> One of the best extensions to deal with scripts is the NoScript add-on for Firefox. While powerful, it is rather complex and difficult to get right after installation thanks to its default script blocking configuration and the need to distinguish between good and bad scripts.

Disallow Script Button is another Firefox add-on that you can use to turn off scripts temporarily on sites you visit in the browser.

It is useful in situations where you are stuck on a website, say one that loads popup after popup, or redirects you all the time around, or prevents you from leaving as you can hit the button it makes available to block all scripts running on it. >

Not too long ago, before Containers? - there was an addon which would pop up and tell me the tabs which were using the highest number of clock cycles. That was useful, I could FIND the tabs running scripts without ceasing.
