Doug could you look at this issue and determine next steps?

It seems like this test occasionally goes over our time budget not because it
falls off of some cliff and hangs somewhere for a chunk of time, but just
because it's big. Accordingly, this patch just splits it up.

Backed out for causing mochitest failures in browser_block_mozAddonManager.js.

Doug, could you please take a look?

There is no need to create a formal uplift request as the changes are only to test files. Just comment if the changes shall be added to 91 (= beta, esr) or not.

I think there's no risk adding them to 91. I believe the file that was split up didn't have any changes made to it recently, so it should also apply cleanly.

So yes, I think adding them to 91 sounds good.
