Assuming it is not due to a keyboard hey repeating, is it only happening with firefox and not anything else ?

One thing I can think of is that you have multiple home pages set, possibly accidentally, try resetting the home page. Another possibility is that you are restoring previous sessions that themselves had multiple windows open, try setting firfeox to use just a single homepage, and not to use previous pages. (Set it to : When Firefox starts : [Show my home page])

• See how to set the home page

Another possibility is some site opening multiple popups, but they are not normally going to be displaying as blank pages. Note Firefox may use the pipe symbol | to indicate blank pages.

I only have one address in address area, as my home page. I have 64 bit and i think i saw 32 bit (says system 32) does this have anything to do with it. Tried your last suggestion, didnt have an icon to the left of my address bar, just a grayed out file. Do you have any other suggestions. Thank you for your assistance.

I am not at all familiar with 64 bit systems, so I will let others comment on that aspect. I do not know the cause of your problem, and can only guess at possible solutions. Unless anyone comes up with better ideas:

• you said "Tried your last suggestion, didnt have an icon to the left of my address bar, just a grayed out file."
  

If that relates to whatever is at the end of the location bar when you try to follow the instructions for setting a home page it should be possible to drag and drop it onto the home page icon. I think one the few exceptions is where you are using a blank page, that has an icon that will not drag and drop. (although there are other ways blank pages can be set to be the, or one of the, home pages used).

Other possible reasons for your problem are given in this KB article

• firefox keeps opening many tabs or windows
  although I think I have a vague recollection the problem with Firefox being set to open incorrect types, and entering an infinite loop may have been resolved. The restore session and malware problems are still definite possibilities.

• I suppose yet another possibility is some other application looking for updates or something, that is trying to use Firefox for that purpose.

When all else fails try using Firefox's [safe Mode]], but do NOT make changes at the first window with the options list, just click on continue, if that fails to help disable all plugins also.

See if this helps you - Firefox repeatedly opens empty tabs or windows after you click on a link

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.

• Help > Troubleshooting Information > Profile Directory: Open Containing Folder
• http://kb.mozillazine.org/Profile_folder_-_Firefox

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
