Is there a way to toggle between the same application? (browser)

You can do that on the Mac by command + tilde, and is very convenient.

Are you talking about something like having two browser windows open and switching between them?

Alt + Tab lets you scroll through all your open programs. Hold the Alt key down and click Tab until the one you want is highlighted.

You can also just use your mouse and click on the tab that you want. I sometimes have four or five open.

However, if you mean switching between open tabs within a browser, you can use Ctrl+Tab for that.
