Days ago, I had many bookmark icons changed in this way: 
Then I followed Synetech's advice at How to refresh bookmark favicons in chrome and that worked to correct the bookmark icons at the sites I revisited.
If I open each website, I get the correct icon again. If it's already bookmarked with the strange icon, I delete it and save it again. But, I have hundreds of bookmarked websites. Therefore, I'm looking for a way to get all correct icons back.
Is there a more efficient way to do this than manually revisiting every one of those websites?
