Someone on another thread was talking about similar stuff and they'd solved it by rolling back to Firefox 3.6.20. Apparently 4, 5 and 6 were all falling over too much. Don't know if that info is any help to you but good luck!

Yes, I had that. It is in the preferences (General / When Firefox starts...)

They've moved the 'actually do that then' to, amongst other places, the history menu and, if you use it, their default start page. I suspect it's partly a plot to get more people to use that.

(Usually with 500+... and yes, the version number thing is stupid.)

They decided that the prompt to save on closing was usually the wrong time for people to make the decision, and it would be better for people to make the choice when starting...

Firefox saves your session by default, so you can get your previous session back by choosing "Restore previous session" from the history menu (or history submenu from the Firefox button). You can make it restore every time using the preferences, as lovingboth said.

As for the version numbering (not that I imagine you really wanted to know)... With the rapid release thing they're doing now (release every 6 weeks, and whatever stuff is ready to be released that day gets released), the 4.1, 4.2 would be tricky, because it leaves the question of when to go to 5.0. They don't plan or know in advance what features are going to be in which release until very shortly before it happens. Deciding to make a particular version a major version jump would require having a debate shortly before each release to decide how to number it, which firstly means everyone spending time debating whether to make the major version jump or not on that release, and also means the numbering might go 4.2 -> 4.3alpha -> 4.3beta -> 5.0. Given that each release is date based rather than feature based, what they could have done instead of 5, 6, 7 would be 2011.1, 2011.2, 2011.3 and flip the major number with the calendar year, which might be slightly more meaningful than just counting on from the previous scheme...

I use the Session Manager extension because it gives more options on how to save/restore sessions than the built in stuff and keeps more history.

With so many tabs, did you notice that you can group your tabs in groups? (In the drop-down menu with the tabs, there is a new option Tab Groups).
In addition to this, I am now trying the extension "TabGroups manager", which allows those groups to be visualised by (yet another level of) tabs. It can also unload groups from memory, to make Firefox use less memory. They will be reloaded when you switch back to them.
I also use "BarTab lite" so that Firefox won't try to load all tabs at once.
