This add-on of Bitwarden is marvelous and especially the sidebar feature on FireFox work well.

Many crashes while using this extension in firefox, also not completely optimised.

Switched to Bitwarden and haven't regretted it for a second. The extension works like a charm in Firefox: autofill is instant, and the interface is clean and user-friendly. A huge plus for being open-source — it really builds trust in terms of security. Highly recommended!

Been using BW for couple years now, best decision ever to switch from built-in browser password manager to a dedicated one.

I currently have BW v.2026.5.1 in Firefox, and I don’t see any slowness. Even with v.2026.5.0 and v.2026.4.0, I didn’t have any problems with sites/logins. The only noticeable bug was on the saving of autofill settings, which was fixed in v.2026.5.0.
Disclaimer: I’m a developer, and I use very powerful PCs.

If other people are still complaining, it may be one (or more!) of the following things:
- They have a slow or very low-end PC
- They have a compromised PC
- They use some particular, specific sites, e.g., Reddit (?) (I don’t use it, so I can’t tell), which may still be problematic with BW

Bitwarden extension has been a total nightmare in Firefox for a while now with no fix in sight.
Freezing webpages, crashing tabs etc.

The extension does not connect with the desktop app and im unable to use biometrics. Unnacceptable

Issue with Firefox has not been fixed for a week.

This worked great in my firefox on windows. Until last week. Constantly pop ups saying it would slow down the browser. Of course, i dont know what the reason is. I have to deactivate it and then activate again to log in somewhere and then deactivate again, and its annoying and feels like i can´t trust it anymore.
I can see that others have the same problem recently.
Dear developers, do somehting or at least give a sign that you read our recent reviews.

DO NOT INSTALL Version 2026.5.0 !
Slows down webpages significantly. I suggest installing the older version, you can do that below the add-on page under the section "See all versions".

DO NOT INSTALL THIS VERSION!
Slows down webpages significantly for some reason. I suggest installing the older version, you can do that below the add-on page under the section "See all versions".

Crashes my browser, terrible update! I can only use my browser if I disable the extension

They've made changes to this that effectively make browsing certain sites painful - the extension consistently stops responding and slowing the browser down.

Horribly optimised

slows down or freezes the browser. regularly runs `querySelectorAll form, input:not([data-bwignore]):not([type="hidden"]):not([type="submit"]):not([type="reset"]):not([type="button"]):not([type="image"]):not([type="file"]):not([type="search"]):not([type="url"]):not([type="date"]):not([type="time"]):not([type="datetime"]):not([type="datetime-local"]):not([type="week"]):not([type="color"]):not([type="range"]), textarea:not([data-bwignore]), select:not([data-bwignore]), span[data-bwautofill]`

not recommended to install, slows down the whole browser constantly

If you have to log in to a third party website a plugin should be avoided at all costs.

You are the product.

A great extension, but recently the extension is showing massive performance issues, slowing down the browser to a halt. Specifically on Reddit for me, for some odd reason.

What in hell did you do to my boy, please fix this crap
