Definitely on the top of my to-do list now. I use firefox more often than other browsers, mainly due to sheer laziness to switch to anything new. The funny part is, I switched to chrome tonight after fleeing three Steem Monsters battle in a row on firefox. Grrr. It stopped happening on chrome. Then I saw your post on the firefox release. Nothing at all having to do with keychain since I have yet to install it. Now I can play eeny meeny miny mo with my browser selection. :)
Looking forward to the ease of having passwords and other cool features easily accessed. Thanks for the update!
