Hi, on my ~slow PPC 1GHz, i've noticed that firefox freezes when it renders
pages that have a lot of javascripts. For example, http://www.linuxfr.org uses a
lot of javascript for messages scoring : when i open several threads into tabs,
firefox freezes until every page has been rendered. "Firefox freezes" means that
i can no longer scroll the current page, switch to another tab, click any link
nor open any menu. The rendering of a single page is not that long as i don't
get the warning popup telling me that some javascript is hogging my cpu.

This is really painful.

Argh. Seems to be the same when I click Install on a WWW page on
addons.mozilla.org to install any Firefox extension (like Adblock). If I switch
JavaScript off, the click results in a windows appearing, with offer to install
the XPI.
