Hello,
While trying to build a regexp for a website, I was having trouble to make it display the data correctly, thus, I tried a "catch all" expression to see if it would work.
/(.*|\s*)*/
This would match any character or space.
This causes the extension top stop working and you need to close and reopen the browser tab to try again.
I hope this bug report helps in any way :)
Cheers!
