I think first we need to check on Thunderbird's startup performance. I'm 
sure there's some things that we can delay until after start-up. If 
there are then we may need extra hooks and things available to be able 
to do this.

Once we have those, then I think we'll be able to communicate the 
experience to add-on authors as well, and push harder on it.

If you mean for extensions specifically, then we have those already. If 
you're specifically on about start-up times, then it'd be useful to know 
where the Firefox pages are then we can look at providing appropriate

I've not been able to look at it yet, but I'd be surprised if that 
couldn't be easily ported to 3.3. AFAIK all the back-end supporting code 
went into core, although there may be one or two bits missing.

iirc that page display an about:startup page, this could easily be done 
in the extension. I'm not sure Firefox do more than that, I'll try and 
find out.
