User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; tr; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1

I have once entered a huge text into a single-line field a week before. It now freezes for 10-20 seconds if I try to enter a text into a field. Then it continues to work properly until I restart Firefox.

I guess that Firefox have saved the text I have entered. When I enter the first  character now, it copies the saved huge text to RAM to show the previous entries below the field. If it is copied in RAM, then Firefox simply uses it from RAM and don't need to import to RAM again. So, it freezes only the first time I enter a text into a field (until I restart Firefox).

I think that Firefox should limit the length of the input (text) which is saved to remember soon, so that it won't freeze.

Reproducible: Always

Steps to Reproduce:
1.Enter a very long text into a field.
2.Copy all of it and paste afterwards. Repeat this many times. It is normal that your computer uses RAM and CPU very high.
3.You may try to post (submit) it (I don't know if it is necessary).
4.Your Firefox will always freeze the first time you enter a character into a field after each restart of Firefox.
Actual Results:  
It doesn't crash but it freezes about min. 10-20 seconds, using system memory and processor extremely high. And it is unnecessary to do all this processes.

Expected Results:  
It should limit the text to store to remember soon, or it shouldn't wait to copy all of the stored things to the RAM to respond.
