No need to be obnoxious.

I noted the tab count because it's a weak measurement of memory requirements, which is directly relevant to the topic at hand.

I keep tabs because they're better in most ways than bookmarks. I'd be happy to expound on that opinion, but I suspect you're unreceptive.

FWIW, Firefox with Sidebery can handle more tabs than you or I need. Someday I'll clean them out, maybe, but I don't need to. Thanks to Mozilla, Apple, and Sidebery.
