I am not able to select multiple objects to then use the Align option in Gazebo. I use Firefox browser.

Hi @andres.alamo ,

Welcome to this Community!

Since you are using a Virtual Machine to do this, usually the left Ctrl button will not work.  
Use the right Ctrl button on your keyboard to do the multi-select. It worked for me.

Let me know if this fixed your problem.

Regards,  
Girish

Hi @girishkumar.kannan,  
Thanks for the welcome.  
I tried what you indicated, but I still have the problem. Also, I tried using Chrome, but had the same problem.  
I hope there is another alternative.  
Kind regards
