Bug#697910: iceweasel: performance regression

[Jörg-Volker Peetz]

Package: iceweasel
Version: 18.0-1
Severity: important

Dear Maintainer,

this version of iceweasel shows a remarkable performance regression
compared to the previous version 17.0.1. The slowdown concerns the
bookmarks menu. It can take up to seconds until the menu opens and the
display of the icons happens visibly one after the other. Also the
opening of submenus takes much longer.
Any idea?
-- 
Best regards,
Jörg-Volker.
