Bug#569905: URL completion bogs down after a few months of browsing, with no way to truncate

[jidanni at jidanni.org]

Package: iceweasel
Version: 3.5.6-2

After a few months of browsing, when the user attempts to type in a
location into the location bar, there will be too many helpful guess
possibilities suggested, and firefox grinds slower and slower... and all
the while the user is unable to fill in where he wants to go.

The user quits and starts firefox again, clicking all the buttons he can
to get rid of all the history he can, but alas, this memory cannot be
removed.

A workaround is, after a few months of browsing, type in
http://www.faceboo... instead of faceb...
That way firefox's helper engine guesses a lot less.
