when switching between tabs and typing something into the find toolbar firefox freezes for a long time
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9) Gecko/2008051206 Firefox/3.0 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9) Gecko/2008051206 Firefox/3.0 When I have multiple tabs in the Facebook application Warbook: Rise of the Infernals I will switch between a tab showing user information to the tab showing the log of all attacks/messages since I started the game and search for the username in the find toolbar which is kept open. Often the first letter of what I type will appear and firefox will freeze for up to 30 sec with 100% cpu usage, then will work as normal and highlight what I was searching for (if present). I can delete what is there and type something else, or type random letters, and it has no problems jumping around the page to highlight what I am searching for. It just seems to be that 70% of the time I switch from another tab and then start searching that it freezes up. Often I open multiple tabs at once, then click one, find a piece of information, and click back to search for that information on messages tab. Reproducible: Sometimes Steps to Reproduce: 1. Click the messages button in the Warbook: ROTI game, then click all. 2. Open another (or several) tab(s), for instance right clicking a user in the log and opening that page. 3. Open find toolbar if not already open. 4. Click back to messages tab and start typing in find toolbar. Actual Results: Took several tries to get it to work. First couple times with a few tabs open didn't work. Open a few more, click a form submission button (I guess, its called Attack in this game) and the page reloaded. After it finished I clicked back and searched for another term and it froze for about 15 sec. Expected Results: Not frozen up.
Freezing of the main thread is - most probably - not caused by the findbar in this case, but because the game tabs are eating up all the CPU time and memory.
