This is, without a doubt, THE best extension I've ever seen on Firefox. Browsing YouTube is now a pleasant, stress-free experience that no longer makes me feel irritated or angry by moronic thumbnails. I just wish we could toggle it for certain channels since I do enjoy seeing Binging Wish Babish's thumbnails, but that's an extremely small price to pay for the peace of mind this brings.

it's great but when i open youtube video it's lag unit somthing happen which i suspect is loading recomnded video thumbnail i have i laptop with 16 gigabyte of ram i think that could be the reson for this lags

Unfortunately it conflicts with "BlockTube", which is number 2 priority addon for me for youtube (3 is being SponsorBlock), so i have to disable it for now. But otherwise it's pretty good so far.

Reply (12.07):
I think i mostly have the default settings, but to be fair, its kind of a little buggy addon by itself, and i never found any better alternative.
It did work ok 3-4 days before that (ignoring the thumbnail and general lag), but after that some videos just suddenly stopped playing altogether, and other ones break mid-play, and disabling "dearrow" instantly stopped all of it.

I have been dreaming of this addon for years. Ajay Ramachandran is a god among us. Thank you Ajay for all that you do!

I absolutely love this addon and the concept behind it, but unfortunately, it seems to be very resource-intensive, causing my videos to chug along and lag for the first few seconds while it attempts to load many thumbnails, on top of causing all thumbnails to load slowly...

I think this add-on is a great idea, and like many other reviewers, I didn't really know I needed this until I turned it on.

Currently, my only issue is that this app seems to really mess with the initial loading of videos, like it will stutter or not start in the first 10~20 seconds before returning to normal performance.

This will only get better as more people start contributing to the process, but even now, not being exposed 24/7 to clickbait and other means to tug at your attention span makes a world of difference.

Edit: Thank you for the response. It seems thumbnail generation service is back online, and as long as local generation performance can be improved, I think that might be the better long term solution, but I'm not here to tell you how to run the add-on.

I am just thanking because this exist.

Does what it says on the tin, developer does a good job. Wish it had more community contributions but that will come with time. Love that it's open source, keep up the good work

I do not agree that there should be a pay wall for late adopters. That makes it more difficult to get good crowd sourcing metrics, which is required for good performance.

I never knew I need this but now I really need this. I just hope you will add Original vs custom/random thumbnail so we could see the original and the random one.

Total utter garbage! Tried it and Youtube completely DIED on me. Pages were still trying to load even after 5 minutes. Nothing worked, I had to close down all my Youtube tabs and it slowed down Firefox something rotten. I have deleted this utter garbage from add-ons. Do not use.

DeArrow and SponsorBlock made my YouTube experience so much better!

Seems to be working. It's by the same dev as Sponsor Block so im keeping it. 👌🏾

This addon most definitely has potential! I find that video's have started buffering... if i click at the video bar on the right I see the video tiles slowly appear. Either way I will keep trying this addon and if the buffering gets bad put it on the sideline and check back on it. Either way 4/5 stars buds! Nice job!

Edit: Thanks for the update! I do understand that it is in a 'Alpha/Beta' stage. I made an account just to give a 'Bug' or 'RFC' or 'Feedback' and once gain thank you for your effort!

Removing the clickbait from Youtube...brilliant, love it, makes Youtube a far more enjoyable and focused experience. Thanks Ajay!

It's so refreshing to not be bombarded by clickbait thumbnails. Plus, the occasional rewritten video title is nice (though I enjoy the ability to temporarily see the originals). The only issue is that it takes longer to load the new thumbnails, but honestly that's not much of a problem.
