Firefox bits and pieces

You can waste a lot of time fiddling with the Firefox addons .....
So I have my 23 things toolbar and my Libx toolbar - any more toolbars and I won't be able to see the #$%@! webpage.
I've loaded Feedly, but I think I'll stay with the Google reader and its folders, and Zotero (more below) and finally, in a fit of nostalgia for the good old (simple) days, I've turned the browser into Foxscape.
Zotero is interesting - with further development could be something really good - I'm using it on my home computer to keep track of the books I read, having reached that stage of life where I have a hard time remembering the title of the last book I read, let alone what I read six months ago. I like the way I can add notes and reviews etc. It did stop working this week - resetting the translators (Preferences - Advanced) seemed to be the solution.
As it's machine specific, I'm using my work installation to figure out which resources, databases etc work with it.
