How many tabs to you usually have open?

How many tabs do you usually have open at once? I usually have anywhere from 3 to 6. Sometimes more if I am doing a lot of work, but I prefer to keep the tabs under control.

Sometimes, I have from ten to twenty tabs open, if only because I've forgotten to close some. Most times, I get super laggy due to the volume of open tabs and end up just shutting down the browser to regain control of my computer. I know there is a much better way to do things. I've tried having several browsers open but feel like that makes me even laggier. Also, I can't stay organized if I'm always having to switch windows.

I have a few tabs open now, including a Youtube video (playing in background); this forum page and a few others from Google search.

Right now I have ten open. It is a lot to manage but I like to be busy so that is fine with me.

It really switches a lot. I'm usually having 4-7 tabs at time, but it switches and depends what I am doing, programming etc.
