Since recently I get this page when I open a browser with a hundred open tabs. It is mendable by refresh, but it didnt use to have this issue:
…any chance of this being suppressed in a reload-previous-tabs scenario ?
I have seen it several times too and in my occasions it occurred because of a timeout. As you also noticed, it is resolved by a reload of the page. Of course this only helps if the internet/network connection is available.
I’m aware whats causing it, but is annoying to have to refresh a page when you are opening a browser with tabs saved. You expect the reload to happen on pageload, which it did until recently.
Just disabled a plugin, can you check if it happens again?
Seen it several times last week. But a refresh made it go away though.
