Such a simple add-on but SO good! Nothing more than it needs to be. Why isn't this more popular???

(tho if I were to make a suggestion, maybe add a tab lock feature wherein you limit it to x amount of tabs, and instead of when you open x+1 tab and it opens in a new window, instead either just don't open a new window at all, OR warn the user they are about to open a new window)

I really love this extension. Mr. Paul is there any way to automatically turn on both the tab limit for x amt and bounce to another window feature when surpassing x amt of tabs for all windows. Basically just auto turning on the fetures and turning them off in the context menu rather than on. I bet its a limitation from Firefox bc I can't find any extension to do this. Either way, thank you.

AWESOME! [I'm using Firefox Quantum v60.0.1]
Works like an Ad-Blocker on streaming sites. Once you have your stream up and going, just right-click and choose 'Limit this window to 1 tab'. When combined with a popup blocker and script blocker this thing makes you bullet-proof from ad redirects that launch rogue tabs.

Hey Paul: You should cross-market this under the usage I suggest above---it will increase your distribution of the add-on. Thanks for making this----works nicely.
