Download Manager

An all new manager lets you download seamlessly, with even greater security. A pause and resume feature means there's no need to wait for a download to finish before you disconnect. So, if you're halfway through the download and it's time to catch the bus, just pause and pick up downloading when you get home. The resume function also works if your system crashes or is forced to restart. The manager shows your download progress and lets you search your files by name or the Web address where the download came from.

Question(s)

What are downloads? Where do the downloads go? Where are they saved? How do they look like?

Free stuff ...

Question(s)

Is free stuff on the Internet bad or dangerous?

Try to distinguish 3 types of free stuff:

Free stuff which is genuinely free. There are lots of people in this world who are honest and share...

  • the whole Open Source movement
  • universities and other educational organisations from all over the world
  • commercial enterprises whose business concepts include "free" stuff
  • people ! lot's of people like artists, researchers, Aurovilians, programmers, writers, - you name them!

Free stuff with small print

  • commercial enterprises whose business concepts include stuff with small print
  • people or companies who give you their stuff free but the free stuff is restricted by time (only valid for 1 month) or not full featured (if you want the full version contact us)
  • in the west be careful that you don't sign up for something using the "free" stuff

Free stuff that appears to be free but is malicious

  • companies whose business concept is based on ripping off people
  • individuals who find it amusing/satisfying to damage your computer or your bank account

Am I safe with Firefox?

Yes - because from the point of software Firefox can be considered as one of the safest piece of software ever written.
No - because YOU are one link in the chain and if you do certain things no browser in the world can safe you. But then - what is it that should be avoided?

  • weak passwords
  • one password to rule them all
  • free, free, free - "click here" !
  • go without discrimination for free stuff on the Internet
  • leave the Firefox window open when you leave the computer
  • don't clear your private data in a public place
  • misjudge fraudulent web sites
  • visit the dark side of the moon - illegal downloads: pirated software, videos, music and ebooks
  • Internet "red light district"

    Handy Hint

    Use your common sense when on-line. Imagine you are in the heart of a big city (maybe even in a foreign country) and somebody approaches you to give you something for free or a good deal or asks for help. What do you do? You evaluate the situation and then decide what to do...
    The same you do on the Internet!
