When I try to login it says "NetworkError when attempting to fetch ressource" Can't use it. Bitwarden Desktop client logs in just fine on the same machine on the same network, Bitwarden works on my iPhone, iPad and Mac but not in Firefox on Windows.

I've used this for years but recently (Oct 2025) having the extension enabled is now making typing in text fields in Firefox slow down noticeably, like it'll often show 2 or 3 letters behind what I'm typing. Disabling the extension fixes the performance problems but then I can't use Bitwarden :(

Bitwarden v2025.10.0 causes stuttering in some JavaScript animations on my site. I tried adjusting various settings, but nothing helped. The only way to fix the issue is to disable or remove this extension.

Slows down YouTube even if autofill is disabled. Slowing down browsers (even Chrome) for over a year. Will try an alternative.

The add-on has massive performance issues and slows down pages a lot, especially if they have many dynamic elements, which is now very common. It often causes freezes and sluggish animations/scrolling.

I was hoping it would stop the constant scanning for form fields on page changes by disabling "Show autofill suggestions in form fields", so it only does its scan when autofill is requested with the shortcut or from extension panel, but it made no difference.

Only excluding the domains worked, but then why have the add-on at that point. Disabling it significantly improved general navigation.

I hope they address the add-ons performance concerns soon, as they have one of the better products out there.

Poorly coded, booting the latest edition of firefox as of 2025/10/17 opens multiple copies of the app asking you to log in to your passwords, doesn't detect settings well, doesn't detect autofill in firefox is off and keeps asking to turn it off, pretty janky rubbish, I expect americans coded this

Doesn't sync with app. Have to manually sync multiple times to get it to work.

does not work. useless. can't log in even though the stuff i'm putting in is right.

Version 2025.7.1 ist leider unbrauchbar: Lässt den ganzen Browser einfrieren!

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.

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 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.

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.

Убогий интерфейс! В прошлых релизах было сильно приятнее использовать

does not always show up on the menu bar or provide login info. Have to repeatedly go to the vault page to get login info.

The UI update is terrible. I cannot copy the username or password like I used to be able to before. Please can you fix this.

I've used this extension for years, and really liked it. However, with the last few updates the UI has gotten progressively worse and less functional. The UI was fine. It didn't need a rework.

Why is the new UI so ugly and useless?

Why is the new UI so ugly and difficult to understand? Has the plugin been hacked?

was good at the beginning but once i got really scared because it was not possible to log in at all. was a wake-up call for me. better use KeePassXC has tons of features and best of all - your passwords are in your hand, not on someone else's PC. you can use Syncthing as well to maintain regular backups and make it available on several devices. never looked back since then.

Franchement très en dessous de la concurrence. L'application et l'extension ont besoin d'une interface plus moderne, et qui fonctionne sur tout les sites. Je déconseille ce gestionnaire de mot de passe.

Terrible.

Never change your password. I did so only because my password was leaked out on the dark web. Since it was similar to the one used with accessing Bitwarden, I changed it.

Bad move.

Now I can no longer sign into the Bitwarden Add-On in Firefox.

However, I can sign into Bitwarden through the online vault, and while remaining signed in, I can then sign into the stand alone Bitwarden application and yet still not sign into the Bitwarden Add-On in Firefox. It refuses to recognize the new password. You can sync the app everywhere and it won't make a difference.

You can delete the add-on, re-add it, restart Firefox, and dance naked beneath a full moon and it will not recognize the new password once it is changed.

Oh, and even trying the original password doesn't work either. Yes, I even tried that.

Also, forget turning off two-step sign in, because no matter how many times you do that, it will turn itself back on again and usually at a time when it is most convenient.

I remember the days when signing into things was a breeze, now you have to bend over backwards and shove your face up your arse to get into even the most ridiculously unimportant sites. Thus having a password manager... that doesn't work with it's own password.

Oh, and forget trying to use it easily with an iPhone. I have the new iPhone 16 and it has been reduced to ridiculousness. It is almost impossible to use it easily without have to circumnavigate Apple's BS making anything but their own password manager easy to use. What used to be a single step process, is now three or more steps. Don't expect to create new passwords on the fly, or for Bitwarden to recognize website that exist within it. You will have to manually got into the app and do it the old fashioned way... click click, type in website and search, click click, copy username, click click, paste into website sign in page, click click back to Bitwarden, click click copy password, click click paste into website password field... and hope.

This is as much Apple's fault as it is Bitwardens, and perhaps more so. Apple doesn't want anyone using anything other than what they can force you to use that they can make more cash on. Which is why I detest them as much as I once loved them when Apple was still Apple before that Microsoft hack, Tim Cooke was taken on as CEO. What in hell was the board of directors of Apple thinking? Profit and ever more profit that was all.

Enough ranting. Now I have to figure out how the hell I'm going to be able to sign into accounts made with Bitwarden when it still worked. Passwords of 135 characters long.
