Don’t do this. It will override the user agent for every site you visit which will cause a lot of problems, like failing most captchas and breaking a lot of websites.

You should use an extension (like this one) to change UA on a per site basis instead.

1. Clean steam files are game files that are unmodified from steam. This means that they will not open because they will check if you own the game on steam.

In order to fix this, you need to crack the game. One way to do this with games that only use steam DRM, is to use goldberg emulator. You can find instructions on cs.rin.ru or in the goldberg repo.

2. Cs.rin.ru is considered safe. Although it is technically possible for someone to upload a virus, as far as I know it hasn’t happened yet.

3. Very good, I would recommend torminatorr (specifically LinuxRulez repacks) to any beginner.

4. Try using bottles instead of lutris, it generally works better for me.

I use this one on my iPhone and iPad and I’ve had no issues.

Onion Browser is decent.

Gestures work no problem in Voyager here.
