Its funny how people are saying that this hasn't been updated in a long time. If you go back and look at the version history there is only once they didn't update for 3 months other then that it has been almost monthly. For the fact that it makes your Firefox run slowly or makes it crash then maybe you have too many add-ons on Firefox I'm not saying this doesn't take too much resources to run but in whole Firefox takes a lot of resources if you keep it running with a lot of add-ons and tabs open. Don't just blame one thing when you for a fact don't know exactly what the issue is because I guarantee the people that have those issues are that too many add-ons and too many tabs open on an unstable system for a long time. If you are trying to keep your passwords on an encryption location then just keep them off the cloud and keep them stored on a encrypted file. No I'm not going to tell you which one because I'm not here to promote any software but do some research and fine something that will do the job. Yes I use LastPass but I also have passwords stored off line in a encrypted file. It does the same exact thing LastPass does. So people that are giving it 1 star and are just trolling because they want to promote another software. Lastpass does the job and if you really think it's taking too much resources, hasn't been updated, crashes too much. Then store them offline and stop promoting other software.
