I use it on Android smartphone, LInux with Firefox, Chromebook, and win8 with Firefox. Never an issue, neverfail. Excellent product. Easy to understand, easy to use. After Bitwarden installed, just start logging into your various protected accounts, Bitwarden will ask if you want them added. Note: go into your browser and make sre to turn off any stored PW, Bitwarden won't do that for you (yet, hint).
