RETURN MY TABS IMMEDIATELY OR PAY

Flash Player doesn't control your tabs, the browser does.  Most browsers have a "Recent Tabs" or "Recently Closed" list in their history.  Keeping a hundred tabs open probably isn't an optimal way to manage them (particularly because you do need to occasionally exit the browser), but you shouldn't let me stop you from living your best tab-filled life.

"When in doubt, reboot" is always sage advice in weird situations, like when your computer only shows a pixelated at symbol.  That's probably the best place to start.  You might get lucky and the browser could offer to reopen your closed tabs, but more than likely, you'll need to reopen them, and any content you were typing into forms is probably lost.

I'm not a lawyer, but I believe that the End-User License Agreement that you agreed to during installation covers any entitlement you might have.  If you have further questions of a legal nature, I believe the EULA offers guidance in terms of contact information, etc.

Finally, you're always welcome to not use Flash Player.  I've included links to the uninstaller for your convenience, below:

Good luck!

first of all, calm down or you won't go anywhere.

Tabs and Flash are managed by your browser, not Flash.

where did you download Flash? browser name and version? OS?
