Frustrating experience of missing search bar Rated 1 out of 5 stars

Version 3.0.5 of this addon removes the search bar, without any explanation/warning.
The worst part about it is that in the "customize" window, it's still possible to add the search bar but it would then disappear as soon as you close customize. This can easily convince someone that there is a bug, but a google search doesn't help at all (found that this extension was installed by chance...)

Instead of making me search all over the place.

I though all Test Pilot studies were opt-in. This is some other, new kind of thing apparently.

On 9 September 2017, I noticed that my search toolbar disappeared. I put Firefox in safe mode and the toolbar returned. I began to disable the add-ons and noticed this "Search Shield Study" thing. I disabled that and my search toolbar returned . When I disabled the thing, there were questions to answer and I did not answer the questions. To me, this is a sneaky, backhanded way to operate. Want to do a study, ask me?
