Googleレンズは好みではないので直接通常の画像検索を行えるオプションがあるとありがたいです

Not as good as the Google Image Search add-on by BringerOfLove, which opens the new tab next to the one with the image being searched, rather than as the last window to the right. The add-on by BringerOfLove also adds the link within the appropriate section of the context window, where this version adds the link to the bottom of the list. The other also has an Icon, this doesn't... but this is compatible with FF57, and it does work.
