SEOBook toolbar no longer in View/Toolbars even after a redownload and full reboot. Video download gone too. Your updates are downgrades to me.
Booted up computer this morning. Auto update of Firefox to 19. No previous tabs available. Eventually restored previous tabs but some of Add-ons didn't work even tho no message to say so. SEO-Book toolbar was there after update but later disappeared. Tried downloading SE-Book toolbar again still did not appear in View / Toolbars tab. Did not appear on screen. The video download prog I had in the Tools tab no longer there. Got rid of download helper as it didn't work anyway.
