Fonts are not fixed in the Firefox browser extention.

[agiUnderground]

Steps To Reproduce

firefox 150.0.1
bitwarden extension 2026.3.0
os linux.

Looks like extention still uses old fonts where O and zero, I and l look almost the same.
Is it because OS or browser forces extension to use different font or some browser configs could cause that?

Thank you.

Expected Result

O and zero, I and l look different.

Actual Result

O and zero, I and l look almost the same.

Issue Tracking Info

• 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.

Could you add a screenshot? (you can fill in fake data to e.g. a new login item and make a screenshot of that)

@pamperer562580892423 turns out that only password field has correct font. Everything else including logins and notes uses old font.

Hi all, thanks for reporting! This is currently the expected behavior based on how we have the fonts configured, but we know this makes it difficult to differentiate these letters. We are going to look into options to improve the readability, so I will leave this issue open!
