1Password does several things well, especially in Google Chrome. However, in Firefox, the 1Password experience is genuinely problematic and highly unreliable.

The most serious issue is that it does not work properly with HTTP Basic Authentication pop-up login windows. In Firefox, I often have to click multiple times and even navigate back in the browser before eventually receiving a different error message, after which the login may finally work. This issue does not occur in Google Chrome.

This has been going on for months. I pay for an expensive subscription, but I do not expect to renew it unless this problem is properly resolved. For my work, I use a very large number of HTTP Basic Authentication links with login pop-ups, and this simply has to function correctly. At the moment, I am forced to click repeatedly or switch to Google Chrome just to get basic functionality.

Support from 1Password has also been extremely slow. It often takes several days to receive a response, which is very disappointing.

My subscription runs until November 2026, but I am already considering alternatives. That is unfortunate, because 1Password does many things very well. However, when it comes to Firefox, the overall experience has been a major disappointment. Judging by the large number of negative comments here, I am clearly not the only one experiencing this.

Sidenote: also the 1Password application for Android phone has issues; it reports 9 out of 10 times, that it has no connection, so all passwords I am adding, do not show up on my desktop. #fail #1password

The plugin is significantly slowing my browser, tested my suspicions on a browser benchmark site and speed score went from 8 with the plugin on and 30 with it disabled (nothing else changed)

glad I found this

Crap application, intrusive, pop ups all the time. Obscure ways to configure, tries to be "intelligent" but of course is not and then hides its internal "guessed" configuration, much less flexible and customizable than Keepass.
When imposed by companies, have to use it, else avoid like hell ! (and do not use it for personal side, your data is on a cloud and a company which is not trustable !)

If you already have 1password account, that has some kind of order, this extension will ruin the order you created by duplicating records you created with records called "Sign in" or something.

Works well for the most part, but it can get annoying when I don't want to save a particular account used for log-ins. The pop-up should have a "No, and don't ask me again" option so that it doesn't come up every time.

It works but introduces severe performance degradation, you can prove this by going on browserbench and running the test with it disabled and compare

Nul. Intrusif au possible. Je dois utiliser 1Password car mon entreprise l'impose... mais KeePass est largement plus adapté. On a sans arrêt des popup au cours de la navigation. Dommage, les options qui auraient pu être intéressantes pour être moins pollué ne sont pas paramétrables. Insupportable. Désinstallé direct.

descent add-on. Please add a mobile compatible version!

I've used this for years with no problems, but recently (within the last few months) it's been hyper-aggressive with the pop-up prompts - even when not signed in. Click out of it and immediately it comes back when you focus on the next field on the same page. It's gotten so bad I've had to disable the extension until the time i actually need it, and then once i'm done i have to disable it again. Not sure what the heck they changed on the back end but it needs to stop.

Breaks sites that use prism.js (code syntax highlighting)

It works good in most of the time, but sometimes it doesn't. Mostly when it comes to OTP it could make mistakes, and also auto-fill sometimes won't work. But it's ok overall..

Works Ok for most of the web sites but it is buggy and doesn't work if I try to use my access key to login in account.samsung.com, it works for other browsers like Chrome and Safari but not in Firefox

1password is great, but this extension - omg.
This is true for all extensions actually, including mobile.
It will just assume that you want to use 1password for everyfield: name? age? postcode? etc... the 1password autocomplete will hijack, hide buttons, misbehave when arrows are being pressed for the default/browser values, etc...
It's the most annoying thing - you have to chose: have a good password completion experience and a terrible for everything else form related? Or the inverse?

Horrible!!
I had to change password manager because of lastpass not being able to prevent a data breach every other week so i opted for 1password!
I regret the day i chose this slopy mess! 1password is comically bad in everything it does

Used 1Pass for about 7 years. Generally pretty solid, and usually the first to adopt new security practices. I like how smooth 2FA is.

The Firefox support could be better—the app always says "Firefox needs an update". Might be Snap related. Otherwise it functions fine. Sometimes the password autofill replaces fields that should be left alone.

1Pass uses a secondary password, called a "Secret Key", it's required when you use a new device. Be aware that you absolutely cannot lose this.

To the reviewer calling it "enshittification"—that's not what that word means. 1P has had secret key as long as I've used it (since 2019), that's long before Cory Doctorow even came up with that word.
