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

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!

doesn't work with plain text

Very good addon.
At the moment, you have to select a bunch of text links, copy them, click on the addon icon, paste them, and then click on Open URLs. It's a bit tedious.

This could be even better & faster if the addon allowed you to open text links simply by highlighting them or highlight & then right-click on them.

Perfect little helper addon. Thanks!

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

No instructions on how to make it work on their webpage and no intuitive way to get it to do anything.

A waste of time.
