What happened?

The list all tabs window is slow to render in with 1500 tabs. Takes around 10 seconds.
I would expect it to render in in sub second times.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.

Thank you for bringing this up but I believe that right now that is alright for 1500 tabs. We can look into this in the future. Closing

How does normal Firefox render 1500 tabs?

[benni347]

In Firefox when going over the Firefox view, View All open tabs, it is loaded instantly for 1700 tabs.

Try using about:firefoxview instead of the button.

[benni347]

In zen that is also instant.

Can you try also using the list all tabs button on Firefox? This may be a Firefox problem instead of a Zen issue.

In Firefox still not instant but way faster than in Zen:

Seems this is legitimately a Zen problem, hope a dev can look into this. For now you can just pin/add as essential and use about:firefoxview.
