How to get mods with the old minecraft launcher for pc?

I just want to use the old launcher, it felt better to use. Now I can't get forge or anything because they are all adapted for use in the new launcher.

Try usiing Multi-MC to Launch Minecraft. It's a great program that does all you need and more.
It also has a built in Forge isntaller.
