Im glad Im not the only one. I have tried everything I can think of, and I dont seem to have any infections of any kind, but Mozilla is molassas in January slow. So slow that using my mouse and typing is ridiculous. I just cant see what I am typing it takes so long to post its likes a paragraph behind my writing. Im on IE (which I loathe) to type this.

Whats up Firefox? I love you......why are you doing this to me?

Im on Vista, I checked all my addons and I uninstalled the only one that said it was incompatible, (HP web something or other) and its no better at all. ANY help at all would be great.

I'm having the exact same issue! Typing it retarded and the faster I type the more it stops responding!!!!!!!

Can someone from Mozilla respond to this or at least tell us that there 's a solution on the way?

I'm running Vista Ultimate x64 at home and Vista Home Premium x86 at the office BOTH machines are doing the exact same thing.

I've removed all Firefox add-ons and it's not having any impact on this issue.

HELP before I get fed up and switch to another browser.

this might be related to the error message:

too many other files are currently in use by 16 bit programs

A workaround seems to be to set the value of files to 100 in

C:\Windows\System32\system.nt

most of it will not work (ie they will have a 'REM' in front of it) however the last three lines do:

dos=high, umb

device=%SystemRoot%\system32\himem.sys

files=40

make the last line

files=100

I still have troubles opening tabs from pages with flash in them

however it certainly has speed things up for me with FF4.0 and Windows Vista Home Premium
