Bitwarden extension has been a total nightmare in Firefox for a while now with no fix in sight.
Freezing webpages, crashing tabs etc.

The extension does not connect with the desktop app and im unable to use biometrics. Unnacceptable

Issue with Firefox has not been fixed for a week.

This worked great in my firefox on windows. Until last week. Constantly pop ups saying it would slow down the browser. Of course, i dont know what the reason is. I have to deactivate it and then activate again to log in somewhere and then deactivate again, and its annoying and feels like i can´t trust it anymore.
I can see that others have the same problem recently.
Dear developers, do somehting or at least give a sign that you read our recent reviews.

DO NOT INSTALL Version 2026.5.0 !
Slows down webpages significantly. I suggest installing the older version, you can do that below the add-on page under the section "See all versions".

DO NOT INSTALL THIS VERSION!
Slows down webpages significantly for some reason. I suggest installing the older version, you can do that below the add-on page under the section "See all versions".

Crashes my browser, terrible update! I can only use my browser if I disable the extension

They've made changes to this that effectively make browsing certain sites painful - the extension consistently stops responding and slowing the browser down.

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.

Eigentlich super zufrieden aber zZ wird dadurch Firefox bis zur unnutzbarkeit ausgebremst.

Wenn es wieder läuft gibts sofort wieder 5 Sterne

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

Can't keep dealing with this extension's issues. There's always a problem with biometrics. Now, there's an issue where, if Bitwarden is running, Firefox starts to freeze/slow down and gives you a banner advising you to stop it to make Firefox faster. Come on. It's always something.

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.
