Bookmarks will not display in sidebar following upgrade to 64 bit version 43.
I upgraded to Firefox 43 64 bit last week. Following the upgrade, upon launching Firefox the bookmark sidebars are blank. If I close and reopen the sidebar, bookmarks are displayed. But if I switch to another Firefox window the bookmark sidebars are blank there too. And if I switch back to the original window, Firefox fails to render the contents of the bookmark sidebar.
I received and installed the Firefox 43.0.1 upgrade, but the error persists. I tried uninstalling and reinstalling Firefox, but to no avail.

Standard troubleshooting via the Firefox SafeMode is the first step.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
