Perfect. Makes me spend less time on YT.

Works as advertised. Very helpful when trying to show videos to toddlers!

love this addon - i found it after trying to cover up thumbnails with multiple Jimmys(sadly not yet posible), id love to be able to pick my own colour for the single colour option.

just came back to say, it would also be amazing if video lengths were on for all modes not just blur

Great add-on. It sadly doesn't work anymore tho. I wish it was updated.

marvelous. makes clicking a lot more intentional and does peak curiosity a bit more based off of the title

This extension is great and does as it says but for the past 2 days, none of the thumbnails on youtube are being blurred. Im not sure if this is because of a setting I disabled or because of a bug but I would really appreciate if it could get fixed.

Excellent. Thank you!

Must have extension, please keep maintaining it

Thank you. A clickbait result came up during a search and the thumbnail was a big close up of something I found very disturbing. I searched for a way to hide thumbnail images and found this. It works. I especially like that it hides them not only in search results but also recommended videos. So, if that horrid clickbait video comes up I still don't have to see the image.

The only issue and it's a minor one is hide unless hovering doesn't seem to work. When I tried that option the thumbnails were just visible. For peace of mind I'm choosing to just hide thumbnails all the time.

love this extension, but i wish it would have a few more options on hiding the thumbnails. i.e blurred thumbnails but they appear if you hover, or the ability to change the thumbnails to a solid color. other than that, i can't complain, it's pretty much what i was looking for! keep up the good work!

This extension is useful but please add these features:
1. Blur thumbnail instead of hiding option
2. Show the video duration while blurring thumbnail
3. On/off keyboard shortcut

This is exactly the extension I was looking for. I watch a bunch of youtube channels & videos with "scary" content, but i tend to hate the thumbnails that go along with them (the clickbait-y trend for ~scary~ videos being what it is - "find the most disturbing visual & distort it into something even less pleasant to look at"), which makes it a slog to scroll through some of the channels i actually enjoy! thanks to the developer for making this add-on available, it works well & makes youtube a more accessible site to navigate. 5 stars

Way better than what i was expecting. Over the years, i have developed a bad habit of going to youtube when I get stuck on a tough problem or just unconsciously. I noticed that the thumbnails where a huge problem because they were the main reason for me picking a particular video. I wanted something like this to deprive my mind of the colorful thumbnails that it uses.

Thanks. This is really helpful.

Great! the only thing missing is a button icon to place on toolbars ("customize"-friendly), to turn it on/off.

Does exactly what it says and shows on the screenshots. Man what a relief for the brain

Thanks a lot @domdomegg!!! This is exactly the FF extension I needed to slow down my Youtube-ing....
