User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0 Build ID: 20180511100427 Steps to reproduce: 1. create new nightly profile 2. Open google.com in tab1 3. Open https://bugzilla.mozilla.org/page.cgi?id=user_activity.html&action=run&from=-14d&who=jdemooij%40mozilla.com in a new tab (tab2) 4. Scroll to the bottom. there is a link in the bottom left saying "show as a bug list" 5. click on that link, AND IMMEDIATELY switch to tab1 6. Let the tab2 load 7. Switch to tab2 by clicking mouse on the tab2 in tab-bar Actual results: page doesnt paint unless you move the mouse inside the tab Expected results: not so Regression: Using url: https://hg.mozilla.org/integration/autoland/json-pushes?changeset=31b295f557db579744feb07900a5aa5e145452b0&full=1 2018-05-11T21:16:42: DEBUG : Found commit message: Bug 1176019 - Fix browser_tabswitchbetweenplugins.js r=mconley After digging into this, I'm still not entirely sure why the timing has changed such that the checks don't work immediately. I have a strong suspicion though that it's simply because our tab switch is now instant, resulting in the necessary messages just being a little bit behind. Hopefully this is an acceptable bandaid.

it could be that tab2 should load in background in step 3. As in, paste+enter the url in the urlbar, then seitch to the tab1 while it loads
