Cpu usage is 100% and firefox 10

Question

I have a question. I'm on dial-up and have a older desktop computer. I guess it's about 5 years old. Lately when I'm on firefox, especially sites with a lot of graphics like ebay, firefox freezes and then I have programs that say that they're not responding. When I check windows task manager, firefox.exe usually says it's anywhere from 120,000-180,000K. How do I get the computer not to freeze? Sometimes it takes up to an hour to close down everything because it's not responding. How do I fix this? Can I tweak something in firefox? While searching google, I found the following info. There was no date on the article. Would this work?:
Lower the max number of HTTP connections
On slow connections, too many HTTP connections may cause timeouts.
In the Location bar, type about:config and press EnterReturn.
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
In the Filter box at the top, type network.http.max-connections.
Double-click on the network.http.max-connections preference, the "Enter integer value" dialog box will open.
In the field, type 30 which was the default value in old versions of Firefox and click OK.

Yes, you can try that, see for more info : [http://kb.mozillazine.org/Network.http.max-connections Network.http.max-connections ]
also if you have this '''network.http.keep-alive''' in about:config TRUE (probably yes)
then type in the about:config bar '''network.http.pipelining''' and '''double-click''' on it to make it '''TRUE''' (it is false by default)

'''BUT''' keep in mind that dial-up connection you have is the big problem for fast load pages, just it is not fast enough, not fast at all.
If you want to reduce memory(60%) '''only when firefox minimize''' ['''and only in windows os'''] there is an easy old good trick:
type in the address bar '''about:config'''
then press the button''' i'll be careful i promise'''
then '''right-click''' anywhere in the list of preferences and choose '''new''' > '''boolean'''
then type in the open window '''config.trim_on_minimize'''(or copied from here)
then click '''OK''', and in the next window select '''TRUE''' and click '''OK'''.
exit firefox and restart-it.
