Hmmm.... can't say I'm familiar with those. Or may not be aware I'm using them?
Basically, if a site supports it...
... it simply opens the site in a proxy container.
Some are more sophisticated than others, 11F has a fairly
rich experience, but, it remains very site specific...,
for example, if you open your
Mailbox in a container, that's basically where you stay, right?
On the other hand, if you're on YouTube, and you do a lot of Multi-tabbing/Searching, than it's a pain in the butt!
It's a nice clean look if you're at your Inbox, for example, but, for normal surfing, I have to have all my tabs and bookmarks in front of me!
