said by Frodo:setting:
browser.tabs.remote.autostart.2
to false should do it for this version. Later on, the preference might be something else, but by putting in tabs.remote the preference should be out there somewhere. I reset the other preferences under tabs.remote .
I'm only slightly familiar with about:config. So, I'm just wondering: Is it ok to change values back and forth like this?
You'd think there'd be an easier way to stop the icon from showing up while switching between tabs.
I'm sure the developers think changes like this have improved the browser, but not really.
Thank you for looking into the issue further,
Frodo.
Since upgrading to 49.0.2, I've also noticed that the browser stalls with multiple tabs open.
Yesterday, I was surfing YouTube (listening to songs) and waiting for a download to finish. For whatever reason, the browser became unresponsive, but the download kept going. Every time I tried to switch between tabs, I'd get the grey icon in the middle of the screen. All menus and icons were accessible, but clicking on them did nothing. The browser just hung for 10-15 minutes before it seemed to catch up with itself.
So frustrating. Also, in general, it just seems slower than ever.
