I miss double clicking on a tab to open a new one
I found this
extension that's supposed to bring that back.
(EDIT: I had said it didn't work for me. Suddenly it does. Maybe it takes two restarts.)
The link above is to the extension's description. To load it, go to Tab Clicking Options at the top of the page in the middle, and click on installation.

each tab requires you to mouse over to it's own "X" to close it where in 1.5 you could just go to the end of the tab bar and close each one by multiple clicks on the fixed "X".
This
did work for me. Open a web page, and in the browser URL strip type in
about:config
and hit return. The strip that appears across the top is a search bar. Type or paste into it
browser.tabs.closeButtons
That setting will immediately be isolated. Double-click it, and a window will appear. Change the number to 3 then close the window. This will return the close-tabs behaviour to the old one after you restart Firefox.

clicking and holding on links doesn't open a new tab like in 1.5
A Mac forum has the following suggestion — but this one didn't work for me, either, maybe because of the previous changes I made.

go to about:config and search for "context". There's a value called "ui.click_hold_context_menus" which is set to false by default. Double-click on it to set it to true, thereby re-enabling the old click-and-hold thingy.
