        They haven't fixed the previous vulnerability yet, I think due to slow Mozilla addon review process.

        Do you happen to know if Firefox add-ons get updated automatically? Trying to assess how much sense crafting a 0patch will make.

        I believe they do, after a long manual review process by Mozilla staff.

        Makes sense (both auto update and Mozilla's review)

        I have a full exploit working without any prompts on Windows, could be made to work on other platforms. Sent details to LastPass.

        Full exploit is two lines of javascript. #sigh ¯\_(ツ)_/¯

        Makes me wonder what the shortest exploit in the history of computing is, in terms of number of bytes.

        That reminds me, maybe Kingcope's old solaris `-froot` exploit (CVE-2007-0882) would be the shortest...

        greater userbase=more prone to being assessed=more vulns found, so it doesnt mean other pwd managers are any safer.
