Open Sim in a New Tab
When you submit a sim, you can have your browser open the sim in a new browser tab by using the "Report and Notification Options > Open sim in new tab" checkbox, middle-clicking the submit button, or control-clicking the submit button.
Your browser may prevent this on the first use and show a warning about pop-ups. Most will show this in a banner bar at the top of the page content and will have an option to allow a pop-up. Make sure you allow pop-ups for raidbots.com to skip this warning in the future.
Note for Firefox users: Firefox will not allow you to open more than 20 tabs at once using this method. Once you have opened 20 tabs, Firefox will prevent additional tabs from opening. Close some Raidbots tabs to open more sims this way.
