Unfortunately Bitwarden has had performance issues on Firefox for over a year. The latest performance issues within the last month now is typing on many webpages is extremely slow with the extension enabled. Disabling/uninstalling it appears to fix the problem.

slow down typing, especially youtube

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.
