How to stop all scripts in the browser or for a specific Firefox tab (if possible)?

Question

JavaScript

I have been researching this issue for a long time, but I could not find an acceptable option. What is it for? When 100 tabs (or at least 50) are open, the browser starts to slow down terribly (and eat resources) and you have to make a choice - restart firefox (it doesn’t help for long) or close a bunch of tabs (and still restart Firefox, because resources, like generally, Firefox doesn't like to free). I would like a real-time tool to solve such problems without restarting the browser or even refreshing the current page.
Clarification - disabling scripts is not required! what is needed is their termination or suspension (with subsequent resumption).
I'm also considering options: instant unloading of all occupied Firefox memory (exactly real unloading, as after forced termination) or a separate tab.
The solution should be ready-made, and not a set of tips from 3 sheets. For example, a button in the toolbar, or in the context menu of a tab, etc.

Answer 1

Tab Suspender

Answer 2

The best solution in this matter is to learn how to use bookmarks, thereby greatly reducing the need to keep open such a number of tabs. My peak number of open tabs often does not reach 10 (at the same time) per evening of active surfing. I highly recommend.

Answer 3

create a blocking operation.

Answer 4

Here is an extension for Firefox
