Firefox "Tab grouping" appears broken by https-e
I recently installed https-e (v3.5.3 stable) on Firefox 26.0 on Ubuntu. It seems it triggers some odd behaviour:
- When I look at tab groups (Ctrl-E) none of the groups have any visible content in them (they're all grey rectangles rather than image-previews of webpages) and I can't seem to click on them to get to the pages.
- Also if I press Ctrl-E to go into the tab-groups view and then press it again to go out of that view, my browser now has an extra blank tab in addition to the tabs it already had.
I deactivate https-e and the weirdness stops.
