How can I actually open multiple tabs of the same site, instead of performing the new "switch to tab" action?

Question

For example, sometimes I would like to open multiple tabs of Google Maps to get directions to multiple locations, and I haven't found a way to do so without open a new instance of the browser. Thanks.

This one colors tabs, but the author warns that it doesn't work with other tab-related extensions, so you probably need to keep searching for one that does everything you want:
https://addons.mozilla.org/en-US/firefox/addon/colorfultabs/
If you don't find a do-it-all extension, you can modify the tab titles with a userscript that is specific to that website. This is because the tab displays the text designated in the page as its title.
You either could "hard code" the list of words for each of the pages, or you could have a script extract information from the page, for example, the first main heading, or some other predictable bit of data. The script then would insert your preferred wording as the title of the page and Firefox will show that on the tab.
To see how that appears, so you know whether it would be useful, you could do this experiment:
On a web page that has useless tab text, open the Web Console using command+alt+k (Windows: Ctrl+Shift+k). In the line at the bottom next to the caret, paste the following code and press Enter:
document.title="Magic!";
If you decide you want a script written for this, you could try the request forum on userscripts''.''org:

Although some people offer small payments, that usually isn't necessary to motivate people to help.
Let me give you a brief warning about that site, though: over the past year, a lot of popular scripts were duplicated and reposted with additional code that hijacks your Facebook account. Be cautious when installing scripts, check the reviews, make sure there are no references to Facebook.
