This is for blogger.com (Blogspot).
In the past 2-3 days a tweak has been made to the site, and now my addon (BBCodeWebEx) is no longer writing to the dialogue window in WYSIWYG mode, though it still does in HTML editing mode, as well as in the title bar.
Looking at the console, I get this: (Ignore the moo, I need to edit that out)
If I do this in the HTML editor, I get:
selection content https <empty string> content_script.js:200:12
moo content_script.js:223:12
And inspecting this text box, I get:
<textarea jsname="bqeLof" class="Fdco1c" style="display: none;"></textarea>
If I do this in the WYSIWYG window, I get:
Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist.
moz-extension://2ae82be5-6163-456b-9115-88560de9366c/context_menu.js:147
context_menu.js:147:30
where that line of the code is:
`browser.tabs.sendMessage(tab.id, clickArg, {'frameId': info.frameId}); // send argument to content script for execution`
The HTML editing window on examination looks like:
<iframe frameborder="0" style="padding: 0px; background-color: white;" class="ZW3ZFc editable" id="nsoPic1772516791250"></iframe>
It’s been about 5 years since I’ve mucked about in JavaScript, so I’m clueless.
