e2: my original complaint still stands since the default is forced for every client and there's nothing to stop everyone else from picking a worse thumbnail just because it picks whever you happen to be in the video when you edit it --- and it being a crowdsourced extension means that more often than not the thumbnails are an out of context or blurry mess. not to mention people editorializing the titles or overly sanatizing them.

e: thanks for the reply - guess i was blind due to the extension being tucked away in the 'more extensions' thing. still annoying that its default behaviour though, especially the thumbnail thing. surely picking a random motion blurred time is more detrimental than a potentially clickbaity thumbnail?

forcing titlecase is obnoxious, really wish there was a toggle for that as it kinda steamrolls the grammar/form of other languages just because they happen to use the latin script (!) or stylistic choices for the video title.

also by default it seems to choose your current position in the video as the new thumbnail even if you haven't explicitly picked it - a lot of times results in people removing an okay thumbnail and it getting replaced with motionblurred nonsense.

i know it sounds petty but if these are my only two bits of feedback then it must be good !

I love letting the community crush the stupid trends of marketing like this. I just wish it was more self-explanatory how to use the tool, as I actually needed to watch the how-to video to learn where to click to make my own changes, and even that barely covered the actual details of how it works.

Simple concept with great execution/implementation!

I love this add-on 💜

I like the idea, but thumbnails appear blank half the time (despite selecting show random screenshot in settings + I have fast internet). In the meantime, I'm using clickbait remover add-on for thumbnails and this for titles.

10/10 best extension I've installed into Waterfox!

I like the idea and the implementation very much, well done and thanks to the author!

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.
