Love it! I have been a 1password user for years.

The latest version hugely improved performances
A must have! Awesome extension.

I've been a user of 1Password for close to a decade now. I was so happy that they made 1Password X for Firefox. I had previously used their browser extensions on Mac and Windows and I knew the integration is stellar. 1Password X did not disappoint. It helps me create unique, strong passwords for every site, auto-fills my credentials upon asking me (without any significant number of false positives, which is exceptionally rare among password managers) and even handles the 6-digit TOTP TFA codes for me. When I had a technical question about the encryption used its developers were more than happy to address it than waving me off or giving me a market-drone reply. That was impressive and what truly sold me; you get to talk to the developers if you have a problem, not some script-reading, underpaid kid packed in a sardine can sized cube halfway across the world. But I digress. The features of 1Password X are well worth the small annual fee, especially if you go for their family plan.

I would love to edit items in the addon and not have to open another page. But otherwise 100% excellent addon.

Terrible experience. When I try to make 1Password to suggest a password in a password field, Firefox becomes unusable. Not just the current tab but any tab. 1Password doesn't respond at all and I have to disable and enable 1Password so that I can at least use Firefox again.

Since installing this add-on and the latest version of 1password I am frequently unable to do simple things like save a new item, without opening the 1Password app and/or the website. The experience needs simplification. Still not sure why there are two extensions (1PX and 1P).

1Password is the best software of it's kind; perhaps it should be considered life-essential. But excluding 1Password 6 customers from being able to use the new extensions is a true disappointment. Heavily investing in the Family iOS and desktop versions in 2013, it's understandable that ongoing development cannot be funded exclusively by new customers, but eliminating the previous extension version without giving users the opportunity to pay for it... again a disappointment. It is likely I'll upgrade to 7, but the change to having my data reside on their servers is of concern - having been president of a technology company I will share that (in general) having the data stored (even in an encrypted format) does hold much higher risk than encryption options used with 6 and earlier. The only online storage we've identified as the safest is pCloud (I'm not a former employee). I'll be checking out specs shortly.

If you have once made an attempt to register with 1password which failed, it is very difficult to register again.
