Per-tab private browsing white / black lists

I've read that Firefox 20 will allow users to open private and public tabs simultaneously. That's cool! For example, I'd love to navigate Facebook, Twitter and Gmail on some tabs, and read news websites on other tabs without telling the former website that I'm reading those news.

My question is: will Firefox 20 have white and black lists for per-tab private browsing? I mean, I'd like Firefox to create new tabs on public by default, but create private tabs of certain blacklisted websites (eg Facebook, etc). Thanks!

Keazen oplossing

The new feature in Firefox 20 is per window private browsing, not per tab.

  • You can have 2 windows open simultaneously in Firefox 20 with one in PB mode and one not in PB mode.
  • The user will determine in which window the new tabs are being opened; therefore, there will be no such blacklist as you suggested.
  • There are visual clues for the PB window, with a different color Firefox button that contains a "mask" at the left end of the Firefox button.

If you have not updated to Firefox 19.0.2, please do so.


You should check your Plugins and update as needed.

A follow-up.

It appears that there may be per-tab private browsing in Firefox 20 for Android only.

And I found this regarding 1). an add-on available for Firefox 20, and 2). a reference to a change in the Nightly Firefox version (as of 03/26/2013, that would be Firefox 22). I have not confirmed any of what is in that article.
