435810 - when switching between tabs and typing something into the find toolbar firefox freezes for a long time

Status: RESOLVED INVALID

(Firefox :: General, defect)

User-Agent:       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.

Since the facebook game is no longer available, can this bug be closed?
