How do install plugins in Safari on a Mac

I use Firefox and love it, but I read that Safari was really spiffy and fast and smoooooth and all that jazz..... so I decided to give a look-see for a bit and possibly change to safari, cause well.. it is a Mac App ya-know and if it's any good, I could clean up my dock and just use Safari (as I have several browsers including safari loaded into my dock and I hate clutter.)

Well to make a long story longer, I have a myriad of add-ons in FF and to find a new one, add it or delete it took me about 42 seconds the very first time I tried it without any previous knowledge of the whole thing, now I can do it in about 8 seconds.

So, the first thing I did in Safari was to go look for plugins, which I found a few....
BUT I have spent the last 2 hours trying to figure out how..... (those with tender ears might want to skip this part because I am going to start cursing about here).........in the @•˙¨ƒ®∂ß´∑ß&#frigøˆ∆ø©ˆ©ƒ¨©¨˙ world do i install the ø˙ˆø©ˆ†√∫ˆ¥ˆ∫ˆ˜¥“ˆø¨things. OR is it even possible.

I know what your are going to ask, because I have been to these forums before:
so here is what I have tried so far,
• Mac Help,
• Safari help (looks exactly redundant to Mac help),
• Apple website (pffffhh),
• Various plugin sites,
• You tube viedos,
• Down loading plugins

(it is not like I am a beginner, I have used Macs since 1984)

I find that ususlly when something is this mysterious and difficult, that it is because it cant be done at all. However I suspect that this is doable.

If the answer takes as long to write as the question did than I will probably just stay with Firefox.

The suspense is killing me.

 

I think it does

There are sites out there offering them ie.

Well I tried downloading one and could not figure how or where to install it.
I just got a jumble of files that I did not understand, when i tried to open them it said there was no application to open it.
