Tor Browser 6.0a1 is released

A new alpha Tor Browser release is available for download in the 6.0a1 distribution directory and on the alpha download page.

This release features important security updates to Firefox.

On the usability front we improved the setup wizard UI flow. We also changed the search bar URL for the DuckDuckGo search engine to its onion URL.

YES. I tried adding it a couple days ago, it's like you've read my mind.

I actually didn't mind the donation banner; the only reason I didn't donate is because I'm broke right now. Will it be re-introduced in the future or are there sponsorships in the works that would help with funding?

We will definitely do

We will definitely do another donations campaign. The exact timing is still to be decided though -- we really want to get our infrastructure better in place for handling donations, before doing a second drive.

Thanks!
