FireFox browser on Win 11. Bitwarden clears first few characters of master password while typing
@Onjai Welcome to the forum!
And this looks like a new and current bug:

bug

### Steps To Reproduce
1. Install and configure the Bitwarden extension on Fire… fox.
2. Unlock Bitwarden by clicking the extension icon.
### Expected Result
The password prompt should appear quickly, and the password field should not clear itself while you are typing the password.
### Actual Result
The password prompt does not appear for ~2 seconds, and any text entered in the password field will be cleared in the first ~3 seconds after the prompt appears. Waiting ~3 seconds before entering text will avoid text erasure.

### Additional Context
https://github.com/bitwarden/clients/issues/18392 is a very similar problem on a different OS.
### Operating System
macOS
### Operating System Version
26.2
### Web Browser
Firefox
### Browser Version
147.0.1
### Environment Versions
Version: 2025.12.1
SDK: 'main (93a331f)'
Server version (self-hosted): 2025.12.2
### Issue Tracking Info
- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

To reproduce:
Open browser
Click on locked Bitwarden
Cursor is blinking in enter master password field
Enter master password
Bitwarden clears characters
I noticed that on opening Bitwarden and you wait 5 seconds, the cursor stops blinking in the field and you can enter master password with no issues.
I tried this several time now and if you begin to enter master password while cursor is blinking on opening bitwarden, then it clears characters
This is a new behaviour that I have not experienced previously

Thanks! Actually, I tried to reproduce it on Firefox several times, but I didn’t see it myself yet…
And Sorry, I forgot to mention before: best thing for you would be, to add your details to that GitHub issue itself. (GitHub is the place to report bugs for Bitwarden)
