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.

yeah what the heck is it doing? quitting and restarting bitwarden on desktop fixes the issue. but you have to do this periodically.

Confirmed here.

Bitwarden 2025.11.2 (51375)
macOS 26.1 M1 Pro 14" MBP

I happen to have reinstalled macOS recently, and experienced this before and after reinstallation, even on the fresh install.

Just wanted to update on the workaround I'm now using daily, which others may find useful. To make my browser usable (e.g. to be able to type in text boxes), I have to keep Bitwarden disabled by default. When I need to sign in to a site, I:

• Open the extensions pane,
• Toggle Bitwarden to enabled,
• Log in, and then
• Toggle the extension to disabled again.

Looking forward to the day this isn't necessary :)

Just chiming in to confirm this issue on my end.

M5 MBP MacOS 26.2RC 25C56 48 hours of system uptime, 3:18:33 cpu time on the Helper.

Like others have said, restarting the desktop app appears to temporarily fix the issue.
