When I first start Firefox everything is fine. And everything remains fine as long as I don't type into any web page's text boxes. I can type into the address or search bar all day long without any problems.
But, for example, just typing into the edit box to ask this question on this site will result in the problem after I type in over say 150 characters. After that typing ANYWHERE in Firefox will be painfully slow, even the address bar or the search bar. It doesn't seem to matter which site I use to type in text. All cause the problem to occur after typing in enough keystrokes.
Browsing & mouse clicking remains fast -- it's only typing that seems to be affected. In order to recover I have to restart Firefox.
If I look at the Firefox.exe cpu usage in Process Explorer I can see that once the problem occurs, the cpu usage starts spiking every time I type a key. In fact Firefox maxes out one of my dual cores so the cpu is at 50%! It drops down to 0% again once I stop typing.
As mentioned in the subject this is in Safe Mode with all extensions & plugins disabled. I am running on Windows XP SP3 with an old AMD Athlon 64 X2 Dual Core Processor 3800+ (1.81Ghz) with 2.00GB of RAM.
I think this started to noticeably happen with Firefox 3.6 (it's amazing how long I can browse without typing) but it used to happen occasionally with earlier versions. Now it is annoyingly repeatable.
I have to use "-no-remote -P ForTyping" to start up a separate Firefox session that I just use to type into text boxes so I can restart it at will. I also compose messages in an external editor and just paste them into Firefox to avoid typing as much as possible.
