If you are using the latest version (0.4.2.1) then, if the site is down, the last version of the board data will be used (but it might take a minuet or two after the browser starts).
If the quick reply etc. buttons are there, then their probably not working because you have ietab installed? I'm yet to find out why ietab breaks the extension.

The latest version (0.4.2.1, or maybe 0.4.2.0 for the janitor version I forget) has caching thought it might take a minute for the local file to be loaded, I'll make this a shorter in the next version. Though if you have boards showing in the menu then the problem is something else.
All of the "4chan" menus can be disabled through the config.
the error you are getting is because 4chans sub-donains have changed, and this requires alot of changes to the extension, and I report features to add to the admin/janitor version of the extension, which takes time, I can build you a version of the latest beta if you like, which most of the problems are now fixed (talk to me on irc).
And no, I'm not going back to the "board data is build into the extension" ways, because its such a hassle to have to release a new version every time something changes (which is usually quite often). It doesn't make any sense to do it that way.
I'll remind you that the extension does NOTHING that you can't do without it, it just aims to make it a bit quicker/easier. And no one is forcing you to use it (if moot is then he shouldn't be!).
