Search Preview does not Work
I have the SearchPreview extension installed, but when I do a search, I get no previews. This is true for at least Google and DuckDuckGo. I have 1.11.917.39 (Stable channel) (64-bit) on Win10. This extension does work in Chrome and Slimjet.
Try my own SearchenginePreview https://gwendragon.de/tools/browser/extensions/index-en.html#searchenginepreview
It is better.
