uhh its good and all but when i have it on, youtube videos dont show and it shows a black screen
bad, my youtube is mixed with werid colors
This is a great extension for youtube. I have really enjoyed using it and it has really been a great tool to use. I'd recommend you to download it and try it out for yourself. I've recommended it to all my friends and family, and they've had nothing but positive things to say about it as well. NIce Job to whoever developed this extension, I look forward to more useful and easy to use things like this.
Completely ruined youtube. Made the site unusable. Complete browser reset needed to repair damage.
the save feature doesn't work and resets to the default black theme >:(
It opened a tab without my consent after my browser was left alone for a while. It was "Addonup.com". I know it was this extension because it's listed on the site it opened. I removed it immediately. I won't use an extension that behaves like a virus and neither should anyone else. There are other extensions that will do this same thing and not open an ad in my browser with no warning it would and no way to opt out in the options. A company that will be this shady just to open an ad for itself is probably doing worse things behind closed doors. People should steer clear of them.
Bro I couldn't even find where to change the color
What made you think anyone would want to use an extension that behaves like adware. Removed.
Doesn't work !!!
Poor. Constantly removes all the changes you made after it updates. I've had to keep a text file with the hex values on.
After 3 days it just randomly stopped working.
It resets and deletes my presets often.
thought it woked but its virtually useless
Doesnt stay when leaving tab
The colors you pick don't stay. everytime you close the browser the colors reset back to default. in addition, you cannot use hex codes to set colors, it doesn't work. your only option is to drag your mouse around on the gradients until you get a color you like. Annoying if you want all the colors to be the same
doesnt work
NOT CHANGING COLOURS ACCORDING TO CUSTOM HEX CODES
at the first, i was quite satisfied with this extension however i guess that there are some glitch because i just spotted my font was invisible on the searching bar
was working perfectly well for like 3 days i actually really loved having a pink youtube.. now whenever i click on a video a black box starts fading in around the video and only when i scroll down do i see the color i chose.. everything else around the video is just black. it does this with all the light colors i choose idk what's going on bruhhh i miss my pink youtube :(((((( i uninstalled the extension and added it back and it still does this..
It's annoying how the progress bar overrules any other extension. I don't want an ugly monochrome colored play bar when I watch my YouTube videos. It limits its purpose -- which is customizability.
It doesnt save when you refresh the page and you can't see what you are typing and the youtube logo bugs out too
Thought it worked at the beginning, but it just ended up making the Youtube icon blank, the search bar not work properly (can't see what you're typing) and doesn't stick after quitting browser.

Its very outdated and doesent change all the colors, you cant change subscribe button like or dislike button colors, it makes the youtube home button color white for some reason, and its built in themes dont look very good.
the colors and presets are fine but you have to reapply the colors every time.
The app doesn't fully function and you have to reapply the theme every time you click a new video or open a new window. I did like the plethora of light themes that the author made
It needs a way to make a certain part default because when you use a color for the search bar you cant see what you're typing
it's not working or i just don't know how to use it
It was super nice but it had a fatal flaw that made it unusable which was it would make it so you couldn't see the font in the search bar. No matter what color I made the top I couldn't see the font until I reset it to default Youtube
Even if I click the color I like on the color selection screen, it is not reflected on YouTube. How can it be reflected on YouTube?
Nice, but I recommend using Stylish as you and put custom pictures and there is way more variety. Also there are custom progress bars there, like Nyan Cat and Loli. But nice job, StickerMania. One thing that annoys me though is the very less choice of colors to use. and you cant use hex codes. In the next update please fix that, if you do I will rate this a 5/5!
I really appreciated the custom color options, and sliding the colors to make custom themes of my own, but the one fatal flaw this YouTube color changing extension suffers is that everytime I try to put in personal hex colors of my own replacing the pre-set ones from the color theme collection, nothing happens. Everytime when I try to hit enter to activate my YouTube colors, nothing works. I try changing the header color, nothing also works. Same goes for the sidebar and content colors. So please PLEASE fix this for a new version update, StickerMania. I really don't want to go sliding random colors all over the place.
Firstly, there is the issue, like others have said, where it resets every so often and all your options are deleted. It also would be nice to have an on and off button. Otherwise, it is a really great feature that I enjoy very much and I'd always use. So I really wish that the kinks are worked out. Thank you.
it would be nice if it didn't reset every like 3, 4 weeks Kind of sucks, it'd be nice if I didn't keep putting it back to its original settings.
Im scared. I clicked open and it brought me to mccafe. it said i had over 68 viriuses im not downloading mccafe because i know its bad and it can slow down my pc
This extension could be so good, but as others have said, when you create a custom theme, it disappears after a period of time. You spend a bunch of time creating some themes you really like- all for nothing when they disappear. There isn't even a way to import/export settings. Though, even if there was, you'd be doing it every other day.
This WAS a great extension but I think they removed a vital section where you can change the color of the YouTube logo itself and a few other text words but they kind of grouped some stuff together so it is less flexible. Please fix this and it would be 5 stars!
not bad, not great, i just wish you could have easier customization to anyones delight & wallpapers
Very cool extension, but the save function doesn't work, so i have to make duplicates so that the presets actually save and there's no way to delete presets, which should be a standard with extensions like these. And i don't know if this is just me, but I have a hard time trying to contact them. When I click "feedback" and hit "submit" nothing happens (just like the save button) and should be fixed.
Simple and great when it works. however.... a) it's a bit fiddly to create your own theme/collection b) doesn't seem to have an option to save/transfer/etc. the theme to a different browser/device c) no separate preview, and it can take a while to load (but that might be a personal, device problem) d) seems to have deleted themes I've previously created/saved after a few days?? as some ppl have mentioned, the text colour for certain video/playlist titles may remain black, which can make it difficult to see when using darker themes, but this didn't seem to happen too often for me.
It's pretty good for any color customization! Only thing I noticed, you can't really like the #shorts when you have the extension on.
i havent tried yet but im going to test now :) edit: its decent but could be better with photo presets
pretty nice! kind of confusing to use (I might just be dumb) but I cant actually see what I'm typing in the search bar. I've switched between light + dark mode and it just doesnt work for me. it works like it says other than that! also the preset saving feature will not work at all.
I was excited about customizing my YouTube. The bummer is that the ppage I create doesn't save :{
Overall pretty good although you have to change it each time imo just keep the browser open if you use it regularly love this sm cos i needed to fully make my browser ADORABLE
I've tried every 3rd party theme extension for Youtube and Chrome literally prevents them from changing the actual Youtube page colors!! Everything is blinding white and the fonts have zero contrast in shading. I hope the designers of Chrome get thrown out of a window 30 floors up. This seem to break Youtube descriptions and comments, just like a certain emoji extension does. Comments and descriptions from other videos that you've watched will be displayed on EVERY other video you watch. Even when I disabled it the bug persisted. Only after completely removing it did Youtube return to normal. It is a weird bug, I am wondering if the idiots running Youtube are actually doing this on purpose because they don't like extensions that do a job they can't. The positive is that it actually freaking works on the fly! I've tried several. One worked then stopped working the same day. This one changes things on the fly and you can drag the color to be anything you like, content, title and sidebar can all be changed, though frequently nothing changes in the sidebar. Thanks for putting in the effort to make such a useful tool! One more one caveat: The like buttons don't change color if you use this.
the extension is good but the problem is that the Header color blocked the search engine
i love this extension but i physically cant use it due to the text not showing up in the search bar. I flipped through colours and every one of them covered the text. would love to use this in the future if is is fixed at somepoint.
How do i change it? I cant see the button!
its ok ig because i cant see the words when im searching up something :/
