Mozilla removed the normal settings toggle a while back, so your options are to manually set javascript.enabled in about:config or use an extension. I agree in general that extensions aren't great, but I trust uBlock.

I think Chrome actually is fine although I don't know of a keybinding for it: Don't they still have a toggle right in the site menu (click the icon to the left of the URL to toggle all kinds of these things)?

In Vivaldi (which I'm 99% certain matches chrome for this part) you click the icon to the left of the URL and then click "Site Settings" at the bottom of the resulting menu where you can toggle a slew of permissions, including javascript.

It's about the best UI I could come up with for this particular knob and the other things adjacent to it.

You can still disable JavaScript via the developer tools. Although it is this session only and auto-reload, so you must tick that checkbox every time you navigate to a new link.
