I would like to use an open source web browser, but I see lots of different places offering a download of Firefox. How do I tell which one is the correct place to download from?

    I'm voting to close this question as off-topic because it is a Firefox support question, not a question relevant to people who participate in open source projects. See this meta thread. – Gilles 'SO- stop being evil' Jul 2 '15 at 17:06
  • There is a possible question about why this is a huge issue for software licensed under floss licenses - adding unsafe stuff into them might actually be legal. But that would involved more research to be a good question anyway. – Michael Schumacher Jul 2 '15 at 17:11

Wherever possible, you should download software directly from the vendor. If that's not possible, use a trusted, preferably secure (HTTPS) alternative source.

Firefox is made and released by Mozilla, so you should download from them wherever possible. The downloads page is here.


There are some indicators I use to determine how trustworthy a downloads site is:

  • Page written in bad English - bad but not 'leave this site now'
  • Page served over HTTP - ditto
  • Page doesn't have a HTTPS version (not just they served over HTTP, but no secure version exists) - bad
  • "FREE! ABSOLUTELY FREE! NO RISK! VIRUS SAFE!" - get away from there
  • If they can't get the name right ("Fire Fox", anyone?) - bad

The best way to know if you are at the correct site is to look for a "clean" link. By this I mean:

  • no subdomains (ie: firefox.download.ca)
  • look for https in the url

In this example, this is the correct link for downloading mozilla firefox:

https://www.mozilla.org/en-US/firefox/new/
