Environment: Firefox 134.0 (64-bit) , Snap for Ubuntu canonical-002-1.0, Ubuntu 24.04.1 LTS Desktop

Jump Cutter is interfering with the operation of my webmail client: Zimbra 9.0.0_GA_4718 (build 20241203044225) . I can log in and see the emails, but when I try to open an email It opens with the subject visible and everything else blank.

I troubleshoot the problem to Jump Cutter by turning off all my addon and activate one at the time. I also use Private Browsing to not have to disable the addon.

The email client has HTML and AJAX options but only the AJAX option fails with Jump Cutter active.

I found a recent related issue with Bitwarden https://community.bitwarden.com/t/firefox-extension-rendering-ajax-webmail-client-unuseable/68565.

I expect the addon to be activated and to read my email from my webmail.

A potential fix would be to integrate a blacklist URL, for example like "Ublock" or "I don't care about cookies". My suggestion relates to the workaround in #181 which relates to #26 (comment)

I confirm that using the handy shortcut of Alt+Shift+X to toggle the extension on and off allow to email to render properly.

Hey, thanks for the report!
That Bitwarden post is helpful.

Do you know how I can test it myself? Is there a free server running Zimbra?

And what is the error message? I wonder if we can do much, besides blacklist / whitelist. Jump Cutter shouldn't be that intrusive to the point of breaking entire pages, especially ones that don't contain any media elements.

You are welcome @WofWca , I don't know were you can get a free running server of Zimbra.

I forgot to mention some settings for Jump Cutter v1.27.5.

In the settings, I checked or choose :

  • 🧪 Use experimental algorithm
  • I want to control playback rate (sounded speed) through the website's UI or through other extensions, not just this one. This will update sounded speed whenever playback rate gets changed.
  • Apply to both Videos and Audios
  • ❌ Don't apply to muted media elements
  • relative to sounds
  • 🔄 Use separate silence skipping settings for different algorithms (related to the "Use experimental algorithm" setting)
  • ⌨️ Enable hotkeys
  • ⌨️🚫 Disable hotkeys while an input is in focus
  • 🔗 Show the "open a local file" link

The error I get in the console when trying to open an email with the feature enabled is the following :

Uncaught TypeError: w.body is null

Followed by another error which also happen in the console once when the page loads for the first time. :

Error: Could not establish connection. Receiving end does not exist. [305.js:2:163](moz-extension://7ec862c8-1eac-446c-aec5-a0ea103d4846/chunks/305.js)

Where z.foo.com refers to the webmail client made available on subdomain z of foo.com

Hmm this is a weird issue.

I'm tempted to blame Zimbra here since it also doesn't work with other extensions with content scripts.
Again, I am not sure if much can be done besides blacklist / whitelist. But maybe I'm missing something. But then we need to debug, a reproduction example.
