last pass password manager and auto form filler have disappeared from my tool bar. How do I get them back or do I have to start all over again.
I am using Windows Vista. Both LastPass and the auto form filler have disappeared from my toolbar. Is there a way to retrieve this information or do I need to start again?

Do those extensions still show as installed in Tools > Add-ons > Extensions?
If not then it is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) 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, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.
You can also check for problems with the localstore.rdf file if toolbar buttons are missing.
