(Firefox :: General, defect)

Attachment: screen shot - about:support with multi-account containers UI open

I'm on MacOS Firefox Nightly 78.0a1 20200521214934. My update history says I was on 20200521093657 previously, and that didn't exhibit this behavior.

Essentially, all my addon UIs are blank. The addon icons to the right of the awesomebar show up properly, but when I click on them, they show me a white rectangle where UI would be. If I click on the rectangle, things happen, so the buttons and functionality are there. The UI is just pure white. I have a screenshot I'll attach.

Disabling all but one addon doesn't seem to help; I've tried a number of combinations. Disabling all addons, or restarting with addons disabled, helps, because I can no longer get to the addon UI.

I had fission enabled a while back, but I've refreshed nightly (purged my profile) since, and I don't have fission enabled currently.

I'm not able to see anything informative in the console.

mozregression came up with this:

which points to bug 1592416, mac only issue ?

ni? Haik for analysis.

I haven't been able to reproduce yet. @aki, could you include which macOS version you're running, which Mac model, and what your display setup is?

Can't reproduce on windows 10, or on mac with only one screen. Needs (at least) two for this to manifest. I'm using Catalina.

Since this isn't a severe regression, and we've frozen updates for all platforms, I'm thinking we should re-enable updates.

Thanks. I can reproduce this now. I'll request the fix for bug 1592416 be backed out. I don't think I'll have a quick fix available.

+1, I'm on Catalina 10.15.4, on a 2020 MacBook Air 13", with an external monitor. This happens on both the external monitor and the laptop screen. This looks better now with the backout; thank you!
