COMPUTER SECURITY: Does the Number of Internet Browser Tabs on Open Matter?

COMPUTER SECURITY: Does the Number of Internet Browser Tabs on Open Matter?

I like two tabs on browsers but use one at times.  For one thing, you can, if stuck in only browser, get information like an email out to save a file if you have two tabs.

Plus, the enemy when you start up already has to make a decision: follow tab 1, 2, or both?

There may be more to this.  It will suffice!
