Horribly optimised

slows down or freezes the browser. regularly runs `querySelectorAll form, input:not([data-bwignore]):not([type="hidden"]):not([type="submit"]):not([type="reset"]):not([type="button"]):not([type="image"]):not([type="file"]):not([type="search"]):not([type="url"]):not([type="date"]):not([type="time"]):not([type="datetime"]):not([type="datetime-local"]):not([type="week"]):not([type="color"]):not([type="range"]), textarea:not([data-bwignore]), select:not([data-bwignore]), span[data-bwautofill]`

not recommended to install, slows down the whole browser constantly

If you have to log in to a third party website a plugin should be avoided at all costs.

You are the product.

What in hell did you do to my boy, please fix this crap

Something has happened in the last 1-2 Days, the extension is now completely freezing all of Mozilla and we are being warned to disable the extension. I hope someone at Bitwarden sees all these reviews and figures out what it is, will fix my review when it's fixed, pinky promise.

Slowed down significantly lately. Even Firefox is reporting that "this extension is slowing us down, want to stop it".

Recently started to slow down and freeze webpages. Firefox asks to stop the hogging bw process

Out of nowhere this extension has began to cause unresponsiveness within the whole browser. Every time I load a new page, Firefox flags it as the culprit.

Great service that I've been happily paying for for years, but this is unacceptable and I will not hesitate to switch to a competitor if it's not resolved promptly.

Impossible to log in on a self hosted bitwarden account from the add-on since the lastest update, which makes it basically unusable.

This add-on began giving a strange error-but-not-really response with Vaultwarden sign-ins for me some weeks ago. Now it’s stopped allowing Vaultwarden sign-ins altogether. Evidently I’ll be accessing Vaultwarden via the browser page from now on. The Bitwarden add-on is dead weight. Removing.

Not really a fan of the new update. The size of the pop-up panel is way bigger for literally no reason (no further info is shown) and the pop-up has a long loading in animation that was not present in previous versions. It is also (for some unknown reason) made more difficult to fill a form on the page, now requiring you to press a tiny "fill" button instead of just clicking on the login you want to fill. There is also a strange bug where as I scroll through my logins the white info-text "Launch Website [Website]" appears in many different locations as I scroll. Terrible update. Will be switching to another service.

What went wrong with this plugin? For some time now it is so sluggish its not even funny. I can type 4 characters of my password and only first one is being recorded in the UI.

Michael Sullivan the new owner of Bitwarden was hired on to gut out the company and churn a profit so Bitwarden can be sold to the highest bidder. Find an exit and alternative like VaultWarden as soon as possible.

Poor UI and extremely slow, got me to cancel my premium.

Makes firefox unusable with memory leak.

Garbage constantly failing, printing cryptic error messages, not taking my pw, not taking my 2FA, reinstalled, works for a few then same crap.

Just garbage, avoid if you can.

can't login, cant change to .eu on extension, it's out of view

biometrics doesn't work. won't connect to the desktop app it says it needs or the native android app.
updating to add the recent version broke the entire vault system. completely useless now.

Integration does not work at all and the team does not know how to fix it. Unprofessional paid service, I am not going to prolong my subscription.

I used this for a long while and still have the app, but the extension's disabled. It reliably fails to unlock the vault, it just loops back to the unlock prompt without even a password field. But at least it's not actively harmful.

Very SLOW. Do something

The slow down still hasn't been fixed, forcing me to stay on version 2025.9.0.
