As far as I can tell, 1Password 3.5.4 is the latest version. When I check the extension, Firefox says that version is not compatable with FF 3.6.13 which I've been suing for some time.On the toolbar there is a big X where the 1 Password icon should be. I tried re-installing an earlier version of 1P, which I was using before, but that didn't help. The 1P support is non-existent, which surprises me. Do I want to trust my apsswords to a company that doesn't even offer reliable support? Do you know of any software comparable with 1P?
