Go to Download Firefox v3.6.17 and download it to the desktop.

Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).

Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox

Finally run the installation file you downloaded to the desktop earlier.

Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

After you complete the installation, go to the Plugins Check page and update those where necessary.

However, before you go that route, here are a few tips to make FF4 look like the previous version.

• Right click a blank part of the tab bar and click "Tabs on top" to remove the checkmark. Tabs will subsequently reappear below the search bar.
  
  
• Repeat the same steps, but click the top one called "Menu bar". This will reinstate the text links at the top.
  
  
• To rearrange the layout, repeat the same steps again and choose "Customize". A panel will open and while that remains onscreen, you can move elements like toolbars, buttons etc around and place them anywhere you wish. You can also drag anything you don't like into that panel and add anything you want by dragging it out of there.
  
  
• To replace the status bar at the foot of the page, install this add-on: https://addons.mozilla.org/en-US/firefox/addon/status-4-evar/
  
  

See screenshot. Both top and bottom views are FF4.

thank you, it worked great. all i wanted was to have menu bar back. really appreciate it.

You're welcome.

I don't like the new look either, but my biggest issue is not being able to use the "Back" and "Forward" buttons. I like and missed (after only a few minutes of using version 4) the ability to choose which page to go back to. Just going back one page is never very helpful. If there is a way to fix that I may upgrade again, but at this point I may just go back to using Windows Internet Explorer.

I've got a non-default theme but you should be able to call up a list of pages by right clicking on the back button or holding on to left click on the arrow for a second or two.

@ CharityLea4_21, install this add-on to get a drop marker on the Back/Forward buttons: https://addons.mozilla.org/en-US/firefox/addon/backforward-dropmarker/

@ukrkoz: In Firefox 4, right-click in an empty space of the Tab Strip and select Menu Bar.

i ended up going back to 3.6.

4 is just beyond me. thanks everyone who cared to response.
