Please update to Firefox 19.0.2 Update Firefox to the latest release then re-explain your problem?

Scrapbook Plus is only supported 'til FF 17.0.3esr, therefore i'm downgrading now ;-(

There is a Scrap Book+ support thread over here:

Thanks for your hint, but there's still no solution for that problem ;-(

I'll have to pin my Firefox-Version 17.0.3esr, until the author of Scrapbook Plus has developed his new Addon-Version.

Thanks

b.t.w.: does anyone know, how to pin this special firefox-Version under apt-get (Linux Ubuntu 12.04 LTS) ?

Does Ubuntu even have the ESR version available??
