firefox hangs when opening directory with a lot of files at ubuntuone.com

[Miloš Mandarić]

Binary package hint: ubuntuone-client

I don't know against what package should this be reported, so if anyone knows, please reassign it!
If I try to open one of my directories in 'My Files' which has about 269 files, firefox hangs for about a 1 minute, then loads the list of files. During the hang there is no internet traffic.

What version of firefox? I'm guessing its parser is being slow loading so much data, and blocking the UI. I often get shorter hangs in firefox on other JS-intensive sites as well.

Version is: 3.5.2+nobinonly-0ubuntu2

This bug is reproducible all the time.

Moved the package bug to firefox-3.5 (as it's the thing blocking on large amounts of JS data).

Added ubunet as project (as there might be something that can be done there to optimize the JS coming from the web ui). I wouldn't know though, someone else on the team might.

I'm assigning to the proper manager so he can set a suitable assignee and importance to this report.
