please, have a look at this document

That document on using tabs to organize lots of websites in a single window isn't helpful to me for the following reasons:

1. I already organize lots of websites in a single window, the problem is that some of these tabs will suddenly be opened in a new window when interacting with them.

2. The section on opening a tab in a new window does not seem to be what is happening to me. It says:

"To move a tab to its own window, click on the tab and drag it below the tab strip. Or, to move a tab from one Firefox window to another, click on the tab and drag it to the tab strip of another Firefox window. "

The second method is the one I have to use to move a tab that has been mistakenly opened in a new window back to the window it should be in, so I know that works and I know that's not what's happening. The first one doesn't seem to be relevant either as my problem does not happen when I click on the tab and then drag it, rather I am interacting with the page inside the tab. For example trying to scroll, or select some text, and then it opens in a new window. It seems to me whenever it happens I have ended up touching the touchpad with a second finger. Is there some way that it could mistake it as selecting the tab, and then my normal scrolling/text selection behavior actually ends up dragging it below the tab strip? If so the document describes my problem, but it does not describe how to fix it, since I am not doing it on purpose.

IS there any way to disable the drag a tab below the tab strip opens a new window behavior?

So to clarify etc.

IS there a way to turn off open tab in new window, since currently the functionality it gives me is not worth the headache.

What would be best is if there was a way to have a popup ask - do you really want to open this in a new window before allowing it, but I guess that wouldn't be likely.
