Can't run downloaded jar files?

I have windows 8 and after downloading jar files (specifically mods for minecraft) i receive the file in my downloads folder or my desktop (tried using both). Firefox, Chrome and IE give me the same problem. I've disabled my norton firewall/antivirus protection when downloading to try and help. Someone suggested going into about: config in Firefox and changing Browser.download.manager.scanwhendone to false however in the about: config page i searched for it and it wasn't there. When i go to Firefox it tells me i'm using the latest version. Other files (such as downloading and installing Firefox) work just fine and it seems to only be jar files. I have tried opening them from the miniature popup in the browser and from their download file locations. Every time i would run/doubleclick or open with java, absolutely nothing happens. Just yesterday (6/21/2014) i was able to run the same file type in any normal way. I do not have windows 8.1 however when i went to reset my computer i did "restart and update". When i go to my java folder i have jre7.

Can I not use Forge mods on Minecraft?

I just bought Minecraft 1.7.9. I installed forge 1.7.2 and tried to run it. It said you have to run 1.7.2 at least once for it to work. So since I don't have Minecraft 1.7.2 does this mean I can't use forge?

How to summon Bosses from Orespawn in Minecraft?

I'm sort of new to modding minecraft and I've installed the mod already. I've looked for the eggs in my inventory but they aren't there. I've tried using the commant box/text, but it doesn't work. Is there anyway to summon Orespawn bosses? I read on their website that I have to find certain items to make it, but I think that's a load of bull since I see the people in videos spawning them whenever the heck they want. Can you help me out?
