My gratitude goes out to a player named Zarcon who has managed to cure all my problems with seeing the left-hand menu. Don't know that this is the proper place to put this but do think someone else might have the same problem someday and this sure will solve it.
1. If you haven't already got it, get the GreaseMonkey addon.
https://addons.mozilla.org/en-US/firefox/addon/748/
On that page, there will be a button to either "Download" or "Add to Firefox" either way, click on it and wait for the install dialog box to come up. Make sure to click the "Install" option on that dialog and wait for it to install(very quick).
2. Restart FireFox after installation of GreaseMonkey
3. Install the script to make the menus scroll with the rest of the page.
http://userstyles.org/styles/33820
On that page, there will be a link/button in the top right to "Install as userscript" for GreaseMonkey users... Click that and follow the prompts in the dialog to install it to greasemonkey.
4. Login to Earth and try to scroll the page.
If these instructions aren't good enough, I can make screen shots of each step and post them on my website for you.
Hope this has helped you,
