no console errors
In the Safari dev tools "Console" tab, the following error is shown:
Failed to load resource: The file “scriptlets.js.map” couldn’t be opened because there is no such file. safari-extension://523679BF-9975-4F60-AA52-C4DFF501648D/b109a5c9/scriptlets.js.map

same here!
fixed in 1.8.3 beta
Just curious - when will 1.8.3 be released? I am seeing this on 1.8.2 as well.
Me too.
As a web developer it's really annoying to see this every time I open my console to check on what's going on. I checked https://adguard.com/en/adguard-safari/overview.html and even the direct-download version is still only 1.8.2. Can you release an update please?
