Well, I guess if one uses tabs, the back button goes to the previous
tab...?
No, it's greyed out, just like on a new window. But...
Other than that, the only difference (vs. new windows) I see is where
the "buttons" are - top or bottom.
When I open a link in a new tab (here by clicking the mouse wheel), and
I'm done with that new tab, I simply close the tab, which brings me back
to the original tab. Unlike using the back button, I don't have to wait
for the original page to reload, because it never went anywhere, and who
knows, maybe I want to keep the new page/site open. Maybe I'm shopping,
and one tab has a list of goods, and three other tabs have different item
details.
I taught my wife how to use tabs with her Yahoo mail. Want to read an
email, click it with the mouse wheel. It opens in a new tab. Done with the
email, close the tab and there's the original list of emails just like she
left it. No waiting. No confusion of multiple Firefox windows showing in
her taskbar. Tabs rule. Back buttons are soooo 20th century. ;-)
However I understand that some folks just flat out don't like'm. To each
his/her own, but I think they're missing out.
