running xubuntu 14.04 Lastpass version is 3.2.21 and I can't upgrade to version 3.2.42 there are two lines on the FireFox Extensions screen:

   LastPass will be updated after you restart Firefox

and

   LastPass will be installed after you restart Firefox

yet the LastPass icon is on the toolbar and I can open my vault.. Neither of these lines have any affect.

I have deleted LastPass and reinstalled... not affect I have uninstalled FireFox and reinstalled .... no affect.

It is possible that there is a problem with files in the profile folder that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled or not compatible extensions in "3-bar button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this didn't help then delete Add-ons.json and possibly prefs.js in case there is a problem with preferences.

You can use this button to go to the current Firefox profile folder:
