LastPass has an extension available for Firefox Mobile on Android OS devices. While it is functional, we recommend using our Dolphin HD extension or LastPass app for use on the Android rather than Firefox Mobile due to Firefox’s limited integration. Bookmarklets are also another mobile option on Android devices. If you choose to use LastPass for Firefox Mobile, you will see behavior very similar to what you see on computer-based versions of Firefox.
Once installed from our downloads page, https://lastpass.com/download.php, the Firefox Mobile extension manager will be listed under the extensions/menu tab:
Your LastPass Vault
To view your Vault, visit https://m.lastpass.com/
After entering your login credentials and logging in, you’ll have access to your LastPass Vault, where you can use the search bar to search for an entry, or scroll down the page to find it. You can then launch the site directly from here and LastPass will autofill the login for you:
Browsing using LastPass in Firefox Mobile
Browsing with LastPass in Firefox mobile is very similar to using the full LastPass extension for Firefox on a computer. You have two main ways to browse sites. The first is launching sites from your Vault, as directed above. The second option is to manually navigate to the website using Firefox Mobile URL bar and typing in the URL. While a site will autofill if you launch from your Vault, it will also autofill when manually navigated as long as the site matches a saved entry (the same as the desktop version).
Autofill and Fill Forms option
If LastPass does not autofill for you, you can always manually fill as saved entry by going to your extensions option > LastPass > Autofill:
You can also use this same menu to access your Fill Forms profile to autofill forms on a page.
