Has anyone tried the new Firefox 4 Beta and if so what did you think about it. One feature (Tab Candy aka Panorama) looks interesting for those of who often have multiple copies of FF running and multiple tabs in each.

Firefox 4 features

I need the extensions to be running before thinking of using FF4

Tab Candy looks useful.

Me 2.

I've got 85 extensions and I bet 70% won't work on FF4.0

I know already that 20% don't work on FF3.6, which is why I'm still on 3.5.9!

I'm surprised that they still show Firefox with tabs at the top.

When you consider that a normal web page is portrait in layout and a normal screen is landscape, why do most people put the tabs at the top? That vertical space occupied by the tabs is precious.

When you put a portrait web page on to a landscape screen, you have loads of space free at the sides. So why not make use of it by putting your tabs there?

And isn't this the place that many utilities, e.g. PDF readers, put their contents list?

How many tabs can you fit along the top before you start having to be clever and using multiple rows or scrolling them or making them so narrow you can't make sense of the label?

If you put them down the left side:

1. You can have 28 tabs, readable since they are as wide as you like. If you open more, a scroll bar appears.

2. Each new tab is indented, showing that it came from the tab above - a bit like a document contents list. You can see at a glance which tabs are children of another tab, i.e. which tabs belong in the same group.

3. You can collapse a group of tabs - as I did in the picture near the bottom - to make more room or just to get them out of the way. The number of tabs in the collapsed group is shown in brackets.

4. You can also delete groups of tabs, bookmark them, etc. All the useful stuff you'd expect to be able to do.

Those are the reasons I can come up with quickly for putting tabs on the left. There may be more.

The extension is called "Tree Style Tabs".

The essential companion extension is called "Multiple Tab Handler".

Both are by Piro Sakura.

Why not put your bookmarks to the side? This require no extension and I think looks much better.
