Its about the Installation tab in Addons Manager. If the order is reversed, e.g. the last installed addon is on top of previous, this problem will gone. Reproducible: Always Steps to Reproduce: 1. Install 4 addons 2. Install some more Actual Results: You cant see the installation progress of 5th, 6th addons etc. Expected Results: Latest installed addon on top of all others.

Valid enhancement, but probably not going to spend time to fix this before the UI is reworked

Intended behavior is for list to default to "Last Updated" order after a restart, so the most recently updated add-on would be at the top in List View.

With WebExtensions being restartless I dont think this is sill valid. UI problems remain in bug 1329884.
