This appears to WFM with the latest trunk build on Windows XP.
Maybe you have caret browsing enabled? Try pressing f7 to switch on / off.

Caret Browsing ON  impacts this problem (F7 toggle).  
      SpaceBar,    Page Up,  Page Dn  have all been
      involved at one time or another in the past.  
      I think Home has always worked.

I reduced the problem for myself with a work-around setting caret browsing to
off in user.js,  so it always starts with being OFF,  but a workaround
is not a fix, and accidentally  hitting F7 will cause problems.

user.js  does not exist by default you have to create it in your profile,  see

You would include the following lines, so that if you accidentally hit F7 and and it goes unnoticed, you would be set up without caret browsing in the next session:

// Get SpaceBar, PageUp, PageDown to work properly if F7 hit accidentally
//   see
 user_pref("accessibility.browsewithcaret", false);
 user_pref("accessibility.warn_on_browsewithcaret", true);
 user_pref("accessibility.typeaheadfind", false);

I would recommend installing the "Open Profile Folder" extension to find
and work with your profile.

I've not had the problem lately, and use of F7 (caret browsing) does not currently mess me up.  The extension that exacerbated the problem the most was "MenuX".  You might find this helpful in setting up and using Firefox:

Thanks, David.
This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
