MutationObserver not firing

[adrianbegi]

I was able to successfully run the optimizer once. Ever since it seems like MutationObserver is not running on var element = document.querySelector("div[class*=backtesting-content-wrapper]") I have tried clearing my cache and even trying to observe on an element on level higher but the code does not seem to pickup any mutations on that or its children.

Always end up with Rejected Timeout exceed error even with a fresh install of the extension directly from chrome extensions.

Ok seems like simply restarting chrome fixed the issue. Don't know why it was happening but didnt occur to me to restart chrome. Closing issue.

Hi @adrianbegi I have also tried extension with multiple computers and didn't have any issues, fyi
