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.

Hi there,

This has been escalated for further investigation. If you have more information that can help us, please add it below.

Thanks!

Thanks for looking into the issue, and taking it seriously: The Zimbra version is 9.0.0_GA_4615 (build 20240415043222) and only affects people who use the classic interface. I hope this helps you to reproduce the problem.

Same here on Windows 10 machines with Firefox 127.0 with Bitwarden plugin 2024.4.2 and Zimbra 10 - also when using Zimbra classic interface only.

Not sure what's causing this but if I disable the option for asking to save and use passkeys in the extension it seems to work again.

I can confirm, that disabling "Ask to save and use passkeys" restores the correct behaviour of the plugin.

I have the same problem, and it is also fixed by disabling passkeys.

[hboetes]

Alright, that's a good workaround, and it will help the devs narrow down the problem.

Hello,

I'm having the same issue and I can confirm that disabling "Ask to save and use passkeys" is a good workaround for now.

[WoutResseler]

Have the same issue and indeed disabling "Ask to save and use passkeys" works as a temporary fix

[zenone87]

This still happens with version 2024.6.2. The above workaround works.

Same issue here with Zimbra 10.0.8_GA_4611 (build 20240412081044), Firefox 127.0.1 and Bitwarden Version: 2024.6.2 Disable "Ask to save and use passkeys" resolved this issue, thx

I can also confirm, like the others, the same behavior.

Zimbra 9.0.0_GA_1337 (build 20220211171033)

Doing the "disable" stuff workaround is working.

Tested on Chrome (126.0.6478.63), with the same option enabled, it's working just fine, so this only occur on Firefox so far.

[Finii]

Same here, broken on Firefox 127 and 128-nightly, ok with Firefox 119 and Ungoogled Chromium 126.0.6478.61

Bitwarden 2024.6.2
Zimbra 9.0.0_GA_4612 (build 20240412104050)

In the popup show mail window the mouse turns into a ... how is that called, circle with strikethrough thing:

Disabling passkey workaround fixes it.

Even if the popup mail window is forced into an ordinary window (via Firefox browser.link.open_newwindow.restriction = 0) there is no passkey dialogue visible (which is I assume the problem).

[syserr0r]

I use passkeys on other sites, is there any other solution?

At present I'm using Google Chrome for Zimbra access as Chrome does not yet appear affected.

[dagobert]

Hi, I also use Zimbra and suffer from the same problem. The temporary fix works.

I investigated further and found something that might help the developers:

The described problem only happens on HTML emails. On plaintext emails the content is displayed. Looking into the source code of the Zimbra page, I found a possible reson. The difference between these two types of emails are that HTML emails are inside an iframe.

I hope that helps to fix the problem. I can give more information if necessary.

[dagobert]

I searched more and found the following when using bitwarden with passkeys option activated.

As you can see, the Iframe content is empty and only filled with the src tag for the JS file.

Same issue here with Zimbra 9.0.0_GA_4571 (build 20230921061510), Firefox 127.0.2 and Bitwarden Version: 2024.6.3 Disable "Ask to save and use passkeys" workaround still working

[dagobert]

I tested the problem in MS Edge using the newest bitwarden Addon. In Edge everything works fine, no problem there.

@dagobert the issue appears specific to Firefox - I have no issues with chrome (and presumably chromium based browsers like Edge)
