Does not work on eBay, after a few seconds the site will freeze up and become unresponsive.

Does what you expect it to do. I have three complaints though.
1: The CPU usage is absolutely absurd. Unless you have a strong PC, you should probably not use this add-on. It seems like it gets worse the more sites you whitelist. I've had to re-install it multiple times to reset it (and I have an AMD 7 3800x).
2: Would be nice to have a blacklist, but as an alternative, you can block elements (or images) manually with an adblocker.
3: Some reCAPTCHAS or websites using Cloudflare simply won't load with this extension. You can't even whitelist them and re-load the website. You have to disable the extension and open the site in a new window to fix it.

I second the opinion that a blacklist would be a welcome addition to this addon!

With Firefox 94.0.1 (64 bit) there is a large amount of cpu used, i tried it on youtube and my cpu go at maximun, need an update this addon for Fiewfox 94.0.1 (64 bit). I deactivate the addons to prevent this bug. With old Firefox version works well.

The most hated app on the whole web. I swear by Fast Image Blocker.

This add-on is good in many ways, but the fact that it lacks a blacklist is a significant problem. It made me stop using it. Wanting to browse with the default being that images are normally active, unless on a blacklist, is not an unreasonable expectation. Having the blocker on by default and constantly adding to the whitelist would be very tedious. Posting this review in the hopes that the developer changes this. Also, the fact that you have to reload before the effects apply is a pain.

There is no facility to export/import the whitelist, for backup and transfer purposes.

It works on some site like Google but it doesn't on eBay for example. Also, I miss the feature of loading only pictures I hover over or select.

Does what it's supposed to do. Would appreciate an extension icon suitable for a dark theme. The icon itself is dark, so it's invisible in a dark theme. Otherwise amazing addon.

Yes, this is very good job. Performs 100%. Great way for this historical era with other competitors

Would there be any way you can create keyboard shortcut to toggle on/off? Other than that does exactly as advertised.

I was looking for an image blocker that would allow me to go to "news" (gossip) sites without being tempted to click on the latest celebrity photos or the indiscreet protestor trend that seem to be on the rise. This did exactly what I needed it to. And when it doesn't, I can add the site to the whitelist in a split second. I can turn it off and on. I tested about 10, and this is the one I use.

Pretty decent app. Does what need to be done.The only reason i gave four stars is that the image should be blocked/unblocked on "Enabling or Disbaling the Button" instead of refreshing the page

it works great!

Simple but effective add-on. Compatible with FF 57.

ページ内画像の表示・非表示の切り替えが、いちいちページ再読込をしないと動作せず、どういう意味でFastなのかよくわからない。希望の機能ではなかった。

Does what it says, even blocked javascript loaded images, which another addon couldn't. No issues to report.
