How to temporarily DISABLE Norton Safe Web Extension without Removing it from Browser?

I want to temporarily disable the Norton Safe Web Extension in my Firefox browser settings.  I need to do this in order to troubleshoot a rendering error I am encountering when logging in to a website.
In Firefox Settings > Extensions & Themes, I see that Norton Safe Web is Enabled.  The 3-dot option dropdown gives me only 3 choices for this extension:  REMOVE, REPORT, MANAGE.  If I choose MANAGE, there is no option to Disable.  I really hate REMOVING the thing because then I have to figure out how to add it back in right away after I troubleshoot the web  page that gives me the rendering error.
How can I temporarily disable Norton Safe Web in Firefox without having to remove and reinstall the extension?
[I will ask the same question of Firefox Support.]
