I would say 15% of the time it doesn’t work and this is frustrating as it is an invaluable tool.
I get this and it never loads
I’ve never waited more than 20 secs in the past but when creating this post I got this:
I clicked the disable labs and it loaded!
I tried the extension again and it didn’t load. After about 45 secs I got the “if that doesn’t work…” window again. Clicking the disable labs did work.
