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 f̶i̶x̶e̶d̶ mitigated somewhat, it took them TWO MONTHS to address such critical issue after being made aware of it on GitHub.

EDIT2: 5 months later the issue re-appeared (2026.4.0), potential fix in the next release.

EDIT3: 2.5.1 did not fix the issue, actually made it much worse on some sites like monkeytype.

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.

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

What I find absolutely frustrating is the apparent lack of synchronization of access data across different devices. It either doesn’t happen at all or takes days to complete.
It’s really annoying to always have to log in to the web version just to access the most current and complete version of your login data.
A manual “Synchronize” button would be extremely helpful!

TOP CLASS !!!!!!! THANK YOU !!!!!!!!

works good, has sometimes problems w detecting username and passwors fields
