User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130119055004 Steps to reproduce: Simple. Start browser, go to www.wiktionary.org. Actual results: CPU usage for 1 core goes to maximum. (I saw 25% usage on a quad core system, and 50% usage on a dual core.) CPU usage stays high until the user scrolls down and reaches the line that says "Other languages". If the user reloads the page, CPU usage goes back up to maximum. I tried Firefox 15, and did not see this problem.

Is this still a problem?
Not a problem any more, as far as I can tell. Checked Firefox 22 and 23, and could not reproduce. Some change before Firefox 22 seems to have fixed it.

Thanks for testing. I don't see much value in keeping this bug open then.
