For the new sidebarAction API we inject the sidebar-button into the toolbar, before the back-button. This is limited to nightly and aurora. We need to UX review this and consider user testing.
Hi Markus, We need ux for this part. Ask Shane (mixedpuppy) for details if not clear.
Hi Shane, thanks for triggering a review of this. how can I experience that behavior currently? (First for review, then probably for user testing.) Is this functionality already in Nightly? If so, where can I find an extension to test it with?
Hi Markus, Per talking with Kev, I'm going to land the behavior that I've created in bug 1208596. This bug should get a comment when that lands. I'll make a simple extension available here as well.
ignore in triage until bug 1208596 has landed and then UX review feedback.
I don't think there is any reason to re-triage this, its just something that has to be done.
