HelpFiddler or cookie finder?

Hello
What is the diference between using fiddler and cookie finder?

I don't understand why some people use fiddler when it's easier to use a cookie finder with a save injector?

Thank you

i had an issue with my internet and i couldn't use proxy, so i had to u use fiddelr
when I fixed my connection it's pretty easy to use cookie finder
and i'd recommend flynn1's finder
