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.

El mejor gestor de contraseñas.

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.

EDIT: The issue described below has since been fixed, however, rating remains due to the fact that it took them TWO MONTHS to address such critical issue after being made aware of it on GitHub.

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

Was working great for years but now it doesn't want to auto-fill the ID and PW with almost all sites. I have a vault with about 100 sites. Very annoying to have to manually copy and paste the ID and PW. Tried various settings including turning off Firefox passwords features.

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

Good, espicially since its free and they dont push you to a subscription
