I've used it for many years. But, after Firefox client redesign it has lost many useful functions, it's not so great anymore.

Ich wünsche mir Einstellungsmöglichkeiten, für das Verhalten des Addons in Firefox, ohne den Tresor entsperren zu müssen.
Bitwarden ist wirklich großartig, aber das Firefox-Addon auf dem Desktop ist mir zu aufdringlich. Es nistet sich in jedes Textfeld ein, ist dort häufig im Weg und solange der Tresor nicht entsperrt ist, gibt es keinerlei Einstellungsmöglichkeiten. Ich möchte meinen Tresor beim regulären Surfen nicht permanent entsperren müssen, nur damit es mich etwas weniger stört.

2025.7.1 and 2025.7.0 have BUG,can't login,told me KDF *******.2025.6.1 is ok.

it does what its suppose to do ty

Version 2025.7.0 is bugged: github com bitwarden/clients issue #15899 If you need to downgrade, install previous version 2025.6.1 from the "see all versions" link on the addon main page.

Marc, ohwnez, Twist3r, Firefox user 14609807, DR, Firefox user 19236894 that issue is going on with all password managers right now which is interesting. Noticed it a while ago.

The last few days when I login with the master P/W Firefox freezes and the cpu utilization goes up. I can only kill it through task manager.
It works fine in Edge and Crome
Please fix it.

Critical issue. Like other recent reviews note, the current version of Bitwarden is unusable and even detrimental. Logging in triggers a runaway process that uses more and more memory and CPU cycles. I am forced to kill Firefox in the task manager before I can do anything else on my computer. A single browser extension using 7+ GB of memory is not normal.

UPDATE: Works as expected again with version 2025.7.1 (so far). Rating changed accordingly.

The developers seem to to be testing their extension at all, as since the latest update, the extension freezes completely on every single installation I've seen.

### updated August 25 2025 ###
The crippling issue rendering the extension totally unusable seems to have been fixed - the extension version that seems to work OK again as I write this is 2025.7.1.
I am changing my rating from 1 star to 4 stars - but not 5 stars, as the previous issue is cause for concern - maybe it could break again. Also the UI / UX has become worse in my opinion in recent redisigns - more clicks to do the same thing as before, and often clicks do not do what I expected.
### end Aug. 25 update ###

Trying to use the Bitwarden Extension in August 2025, it caused Firefox to freeze for 10+ second for any operation, and the extension didn't even work - trying to fill in a password would just cause a 15+seconds freeze, and after that the password was not even filled. Disabling the Bitwarden extension caused Firefox to become lightning fast again as usual, immediately, so this was really a problem with the Bitwarden extension. This is totally unusable and unacceptable, and very sad as Bitwarden is a great service. The extension worked perfectly the last time I used it a few months ago, so this is a new issue (in the meantime I was using the Windows App, which works fine). I really hope this will get fixed quickly.

Latest update is completely bugged. The whole extension goes into panic mode when you first try to log in. Have to restard the whole browser to fix for now... Needs a critical update asap it's non functional as is

The last update do not work properly the add-on icon still in gray colour and when I enter the password to unlock the vault it causes Firefox to shutdown accidentally fix that please

The latest version lags out enormously and uses a mind-boggling amount of RAM when logging in, making Firefox go from less than 1GB of RAM usage to just shy of 11GB. It freezes the whole browser for ~30 seconds while doing so, before finally letting all that RAM go and actually logging me in. I'm not sure if it's compromised, but I've tried reinstalling Bitwarden and I get the same results. The addon has been nearly flawless for years before, so I'm hoping this is just a temporary issue, but as it stands I find it unusable and highly suspicious about what exactly it's doing to use so much memory and freeze the browser.
