UPDATE: Auto fill and field fill drop-down options don't work in the latest version. Downgrading to 2025.8.1 restored the functionality.

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

Now it is fixed it is very good after two monthes

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.

Very easy to set up and use and connect to your own vaultwarden server too. have not had any problems

The extension forces me to enter a password instead of using my biometrics. This error has been occurring for a few weeks; it worked flawlessly before.

Logs me out every few days even though I use it every day. This is insane.

I'm disappointed that bitwarden doesn't take potential security exploits very seriously, months after a proof of concept that shows that the extension is vulnerable to data exfiltration a resolution is still outstanding. It's hard to continue to have our organization use the service when users have to be instructed to disable the auto-fill functionality.

I find it mind-boggling that the chromium version is at v2025.7.0, while the one on gecko is still at v2025.2.0, which is still dated March 21, 2025... why don't you update it? It's a great extension but I find that the version gap is just huge... the version on the add-ons is listed as v2025.6.1, but I can't update it on my browser I'm stuck on v2025.2.0

Easy Helping me

Ich komme von einem anderen Schutz-/Tresorprogramm. Inzwischen setze ich Bitwarden seit ca. 4 Jahren ein.
Sehr gut gelungen ist die Synchronisierung zwischen der Android- und der Windowswelt auf verschiedenen Geräten. Gut gelungen sind (meistens - selten klemmt es anfangs bei Updates von Browsern) die Eintragungsmöglichkeiten im Browser von Firefox, Chrome, Edge, duckduckgo, u.ä..
Die Einstellungsmöglichkeiten sind vielfältig, aber es fehlen an allen Ecken und Enden Best-Practise-Beispiele, um zu verstehen, wie die unterschiedlichen Einstellungen effektiv genutzt werden könnten. (Excel hat genau solche für die Formelsammlung - hier würden sie ebenfalls effektiv helfen). So rätselt man gerne mal, was bei bestimmten Formulierungen in Hilfe, Beschriftungen, usw) wohl gemeint sein mag. Ein Beispiel? Auto-Ausfüllen => "Vorschläge anzeigen, wenn Symbol ausgewählt wird" => klar soweit? Symbole auf Handy, Desktop von PC, Menüleisten-Symbole .... ? Selbstgewählte Symbole auch?
Sicherheitstechnisch fühle ich mich gut aufgehoben. Kostet ja auch.

switched from lastpass in 2015 after their systems were breached. turns out that was a good move because lastpass has been breached again in 2022 and 2023. bitwarden is opensource and has never suffered such security failures. its beautiful, easy to use, and packed with features, all for free.

I love it. Bitwarden has both finally and successfully overcome the 'Bad GUI' curse of open-source software with a their beautiful user interface panels.
