Extensions no longer functioning after firefox refresh
I refreshed Firefox, now Lastpass and Ghostery don't show up in my toolbar or work anymore (Mac OS 10.9.5). I removed the Lastpass extension, then reinstalled to no avail. Oddly, Adblock Plus is in my toolbar and works fine. Attached photo shows Adblock, but no Lastpass or Ghostery icons in my toolbar.

What kind of preference changes? I have one in mind that could have unintended consequences.
If you change Firefox to using automatic private browsing -- on the Preferences page, Privacy & Security panel, History section, either:
- Firefox will: Never remember history
- Firefox will: Use custom settings for history + [x] Always use private browsing mode
-- then your extensions need to be enabled for private windows or they will not run.
On the Add-ons page, if there isn't a purple mask icon next to the extension's name, click the name to view the Details panel, then scroll down to where you can grant permission to run in private windows.

It’s possible that there is a problem with the file(s) that store the extensions registry.
Type about:support in the address bar and press enter.
Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.
Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
After, restart Firefox.

+++++++++++++++++++++++++++ You will have to approve the updating one last time.
Did as you recommended, but no go. Removed the extension files, etc, reinstalled Lastpass and Ghostery, but they still do not show up in the toolbar (see attached). Lastpass, Ghostery show up as "enabled" in my Add Ons manager. Was unsure what you meant by "you will have to approve updating one last time." Appreciate your help, thanks!
Look at the far right of the toolbar. Do you see a double arrow? Press it.
No, no double arrow. I trashed Firefox, including any folders. After reinstalling I was able to add Lastpass, Ghostery and Adblock Plus. But after making changes to some preferences in firefox, they disappeared again. I trashed Firefox a second time and re-added the extensions. for the moment, they are showing up in my toolbar area, but I have not made any preference changes. Not sure what the heck is going on, but thanks for your assistance!
You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no
Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Thanks Jscher2000 ! I was changing that setting for History, and think that's what kicked my add ons off my toolbar. Appreciate it!
