Downloading and caching images in Firefox, as well as in Opera

Previously, "sat" on Opera. But, for about 1.5 years, I moved to Firefox. What I lacked in the fox is caching and loading pictures in the same way as it is implemented in the opera.

Before I started writing this topic, I wanted to write another topic on the topic “how to cache pictures in Firefox?”, But decided to try searching the Internet first.

And, oh, a miracle! I found :) It turns out there is a wonderful addon called ImgLikeOpera. You can download it here . After installing and restarting the browser, this addon appears in the lower right corner. How it looks in the opened form can be seen in the example picture above.

I hope I also helped someone with this question :)
