Issue on Zimbra Webmail

[Parvares]

Hi Mike,
I'm trying to use your extension with Zimbra webmail in Chrome, but when I click on the target URL, nothing happens.

In the Chrome extension settings, the "Site access" permissions are set to include all sites, and the extension is enabled in "Incognito" mode. Interestingly, the extension works perfectly when I'm in Incognito Mode on the same webmail page.
For reference, Chrome’s embedded context search works as expected.

I receive the following error from the Chrome extension page:

Uncaught (in promise) Error: Cannot access "about:blank" at origin "https://mail.bibliotechediroma.it". Extension must have permission to access the frame's origin, and matchAboutBlank must be true.

Could you help me troubleshoot this?
Thanks very much!

Can you elaborate on the issue a bit, since i can't log into that website? Are links broken? What do you mean by "when I click on the target URL, nothing happens"?

Interestingly, the extension works perfectly when I'm in Incognito Mode on the same webmail page

That's interesting. Definitely a place to start.

Hi, I noticed two issues, both in normal mode and incognito mode in Zimbra. When accessing the extension from the extensions bar, a new page opens, but the search function fails to work as expected. The extension almost never works properly from the context menu within Zimbra. Specifically, links almost never open when selected. Please refer to the attached video for comparison.

This is the code of the webmail page (I have removed some sensitive information for privacy reasons), link.
This is what ChatGPT suggests: link.

Hi Mike, I noticed that the extension with Zimbra webmail works perfectly from Firefox, but it still doesn't work from Chrome.

[ssborbis]

Did this get resolved in any of the recent releases?

[Parvares]

Hi Mike, I've updated both the browser version and the extension, and I've tested it on different PCs. It works fine in Firefox, but it still doesn't work in Chrome.

Here are the new errors I see on the Chrome extension page, let me know if you need any additional details.

Is Zimbra webmail the only site you're seeing this behavior?

[Parvares]

Yes, only in Zimbra webmail, excluding Firefox browser, where Zimbra Webmail. works fine.
