For the last couple of days I have had to restart Alitools to get the search by image button to appear at all.
However, the search does not work when you click the button, nothing happens at all.
In my opinion, the program is getting worse instead of better, because when you make a purchase, you always get the nice hint that you are looking for better offers, but Alitoos has never found anything else to date. I haven't used this option for a very long time because it just takes time and has never brought any result. I'm seriously considering uninstalling Alitools because the extension is useless.
