Been using Open Multiple URLs for quite a while now and does what it says.

Does exactly what it says on the can. I could be improved by detecting the open tab and extracting the visible links on the page by clicking the button, or even better, this could be set as an option. This helped save my lost session with +2100 open tabs.

Came to my rescue when Firefox couldn't sync thousands of tabs.

Simple, easy to use, yet the "do not load tabs until selected" and "load in random order" settings make this add-on probably the best bulk URL opener there is fore Firefox. TY!!

It works super good. I am switching to Firefox from Chrome; this is the first extension I installed. Thanks for awesomeness.

Najlepszy!

Perfect little helper addon. Thanks!

This extension is extremely useful and was very helpful to my workflow involving switching between many tabs at once.

Excellent. Simple add-on to serve its purpose and only that.
Managing multiple set of URLs would be an added advantage.
Expecting the option to import/export URLs from/to text files.

Excellent, does what it says it will do, and only that. No fancy stuff, straight to the point. Good job.
