A problem with Firefox on a used/rebuilt Dell Inspiron laptop

This is a used/rebuilt Dell Inspiron 3541 laptop that I just got not to long ago. OS Win7 Home 64bit. When I am typing (like in this box for this post) it is taking anywere from 3 to 5 seconds for the words that I just typed to show up on the screen. It doesn't matter whether I use the internal keyboard or the external wireless (Infrared USB Plug) keyboard. Firefox is also very slow in moving between tabs and loading new pages or going back to an old page. The yellow "auto save" box that pops up in the lower right corner of the typing box when I am typing a post makes Firefox even slower. Other prog's that I have that have internet connection, like Remotehams.com live streaming remote base control prog aren't effected by what is slowing Firefox down. And the rest of Windows is fine. I have the latest version of Win Cleaner on a USB thumb drive. It didn't help Firefox. It isn't a big problem, just annoying, waiting for the screen to catch up. Especially when I have to backup the cursor to correct spelling. A question. I only have 4gb's total of memory. Is win7 64bit to much for the ammount of memory that I have? I do have the Win7 Home 32bit install disk also.

Hi

is it the same when using other browsers?

No. I am using Internet Explorer now. And IE is working fine. No slow down's, no delays with the words coming up on the screen. 1 other odd thing though I don't know if it is connected with the Firefox problem or not. In DreamMail, my mail reader in my laptop. Every time I open the prog there is 5 or 6 of the same email in the outgoing folder. They don't get sent until I hit the manual send. And I don't compose any of them.

Have you tried rereshing FireFox?

To Refresh Firefox:

1. Open the Troubleshooting Information page using one of these methods:
   
   • Click the menu button , click help and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
   • If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
   
   
2. At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
3. Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
4. Click Finish and Firefox will reopen.

After about 5 days Firefox is right back to doing the same old slow things again. As described above. The "reset Firefox" worked again. I am thinking there is some spot ether in the memory or on the hard drive that needs to be expended. Witch leads me to my next question. I only have 1 stick of 4gb of memory. Is Win7 64bit taking up to much resources?
