Extension verbindet sich nicht mit der Desktop App.

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)

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.

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.

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

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

This addon just never works. Constantly being taken to the website to log in for some reason. I don't want a session open to my password manager in my browser. This extension should integrate with the desktop app...not the website. That is how it used to work, if the desktop app was unlocked...the extension worked. Poor browser addon is going to convince me to leave this trash behind...

It throws exceptions in the console when tyring to open any action from within the web page

"Uncaught TypeError: window.crypto.randomUUID is not a function"

The fact that you have to jump through so many damn hoops JUST to use this thing is needlessly complicated.

And the fact that you *have* to rely on a stupid secret key, or else you're just straight up locked out of the application is horrendously bad design.

Enshittification at its finest. AVOID.

1Password forces me to press the extension button on my browsers toolbar instead of just being able to press the 1Password button embedded in the password field. 1Password UI hangs over important information in the browser and often covers up the "Show Password" button. The UI is clunky and looks outdated, and frustrating to use. Would not recommend, and have uninstalled the browser extension. I will just use the desktop app.

Seek a better password manager

The extension does not respect the "Offer to save logins" switch and prompts me on every. dang. page. load. for sites like the AWS console.

0/10. Super annoying.

As of 27-Jul it's broken - doesn't work with latest firefox at all. Was great, but now unusable.

Same problem others have reported. It no longer works properly in Firefox. I figured out a work-around: If you click the 1-Password add-on and it doesn't work, then turn it off through Manage Extensions (no need to uninstall). Then close Firefox. Re-open Firefox, and turn the 1-Password add-on back on (through Manage Extensions). Then it will work fine until you restart Firefox again. Hopefully they will get this resolved soon...

Uses 100% CPU, blocks other extensions from running.

The 1Password extension work very well for a year, but about 4 days ago it wouldn't open. I deleted the extension, restarted and reloaded the extension. It worked for 2 days and then again it wouldn't open.

Funktioniert nicht mehr unter Firefox

Was working great, then a few days ago it quit working in Firefox.
