I just want to view not edit tabs and I think paying 60 bucks to listen/edit is too much.
There's also TuxGuitar. It's not as good as Guitar Pro, but should be enough for your needs.
My favorite is TabToolkit for iPad. If you have an iPad, it is $10 well spent.
I know the title says free, but in the questions you said that $60 is too much. I agree, but I don't think $10 is too much.

Guitar Pro Tabs Online Viewer:
and many more...
is an online Guitar Pro playing site. It's a "freemium" model, where the free version gets you limited functionality (from memory):
- No turning individual parts up / down / off / on.
- No printing
If you subscribe then those limitations are lifted, but...a year of it costs more than Guitar Pro! I just got it for the purposes you describe - and as a backup band! I thought it was worth much more than the $50 I paid for it. Check Amazon, Guitar Center, etc.. for discounted pricing.
There are Chrome extensions to view guitar pro tabs directly online: https://chrome.google.com/webstore/search/guitar%20pro%20viewer?hl=es&_ac=0
