it's not allways work, i use 66.05 32 bytes
i tested on www.multcloud.com, the image from folders not load correctly
i put whitelist, change load all images, and still not work

проверил на гугл мейл, блокировка работает, но выборочный показ не работает. мне пришлось отключить это дополнение, чтобы гугл мейл стал показывать картинки

Load Images in the context menu doesnt work anymore (or it works sometimes, and sometimes it doesnt).

キーボード操作（ホットキー）による切替がほしい。さらに、そのホットキーをカスタマイズ出来るようにして欲しい。

Usefull, but breakes functionality on some sites. By example, with addon don't work payments in Yandex Money (button Pay dont work).
2) "Reload page when load image" doesn't reload automatically.
FF 52.5.3 ESR win 32.

Please fix problems.

I've been looking for a simple image blocker compatible with Firefox 57+ beta and found this.

Features: Can block all images, has a whitelist, can Import/Export whitelist, placeholder options (None and ALT String), each tab can have a mode independently, take over mode from current tab (new tab will have same mode as current tab), hide context menu extension.

Verdict: It can be a simple image blocker for beginners, and has options for advanced users.

EDIT: After a couple more hours of browsing, I've noticed it doesn't block images on some sites even with block all sites enabled (best example: Wikipedia). To the dev: Any particular reason, or is this a problem on my end? I haven't made any changes in settings.

Also, it blocks social media buttons on some sites, but not all of them (e.g.: I can't see the Like button on Twitter, but Reply and Retweet are visible). This could use a fix.

ALSO also, it doesn't remember my choice, it seems. After I'm done browsing, I unblock images & close Firefox. But when I open it again, the option to block all images remains enabled. I thought this was a great add-on, but now I'm starting to doubt.
