This is likely a bug in Firefox, not WebExtensions, now that I'm thinking more about it...

The problem is that when selecting a tab that's been suspended using tabs.discard(), the URL bar is briefly blank, before filling in with the URL.

This is quite visually jarring.

Easy example is using Dormancy, and add-on I wrote that suspends tabs after a set amount of time: https://addons.mozilla.org/en-US/firefox/addon/dormancy/

Yep, I restarted Firefox, and see the same behavior when selecting suspended tabs in a restored session.

Switching product/component.

So this sounds like a more general bug regarding lazy browser loading.

A short screencast that demonstrates the issue (the glitch you're talking about) would be very useful! :-)

So some months have passed, and I think the behavior I'm seeing that feels glitchy is:

1. See an unrestored tab, has the correct favicon and title

2. Select it

3. The tab title goes blank (<-- THE GLITCHY PART)

4. The tab title fills back in as the page is loading

IIRC favicon is cleared and reloaded as well.

Sadly... I don't see this *all* the time, only sometimes.
