Need browser option for OS 10.7.5

hello all.
1st post here.
I am a recording studio engineer.
My back up rig is a 2011 imac with Pro Tools 8LE. I CANNOT update the OS or I will lose my Digi 002r PT8LE function. I NEED a browser option. Have tried chrome, safari, IE and fire fox with no luck... Any ideas. Thank you all. My current rig is a 2017 imac with 32 g ram and running Pro Tools 12 on a moded Digi 003r.. hope i havent broke any posting rules. Apparently not a single major browser still supports 10.7, and even some of the less updated smaller ones, last one I could find was cut off at 10.9. Would it possibly be a better option to network your two machines and have the ability to move files over, if that's what you're trying to get via browser? I'm not seeing great options for 10.7 at all here.
