Stylish - Custom themes for any website

Sadly all of the styles are shown as added even though theyre not and i cant install any style :( (please fix this bug)

the extension is alright by itself, problem is the website has a major bug where you just cant add any styles due to it showing every single style as added ALSO ADD IN PROPER MODERATION, THERE ARE PEOPLE POSTING BLOODY NSFW LEFT RIGHT AND CENTER AND SOME OF THE TIME IT ISN'T EVEN CENSORED!!!! like dawg i have seen literal CROPPED NSFW.

it says i added the style even though i havent even added it please fix

i can't download styles. For some reason it says "added" but i didnt even click anything. And it didnt even add. I dont know why. I tried refreshing and reinstalling the extension but it didnt work.

its bugging it says i added everything but i didnt fix it please

Even when I try to add a style, it shows as “Added,” so I’m unable to add it. When I try to create and publish a style, I get the error message “An error occurred, please try later,” and it does not get published.

Fix YOUR extension please, thank you.

Installed it, immediately asked me to give it permission to read information from the website I was visiting, and I can't add styles unless I create an account. Uninstalled within one minute

Basically asks you each 2 secs to login just annoying and disfunctional pick dark reader instead

It doesn't even work.

Consider uninstalling the malicious Stylish extension. In 2016, with no input from the userbase, through some guy, pretending to be an independent developer, it basically was sold to a shady web analytics company, Similarweb. Since then, it is actively sharing your entire non-anonymized browsing history demo with them, assuming you ever clicked on one of the flashy "Agree" buttons. It initially did this without even asking for consent, and was banned from extension stores afterwards. Currently, it still breaks store policies, yet is not banned for unknown to me reasons. do not install this install stylus instead

I can't create or use any style.

Clickbait nothing but anime with no way to delete account

Used to be perfect. Updates ruined it over the years. Completely unusable and bloated now. Do not use. Go with Stylus.

Wouldn't let me create a custom theme without creating an account and publicly publishing it. I tried to delete my account and data since I won't be using this anymore, but there is no way to do so.

**URGENT WARNING: Uninstall the Stylish Chrome Extension NOW—It’s Spyware Linked to Israeli Data Harvesting** The Stylish browser extension, once a popular tool for customizing website appearances, is **actively spyware**. In 2018, security researchers and users exposed that Stylish was **secretly logging every website you visit**—including sensitive pages—and sending that data to servers controlled by **SimilarWeb, an Israeli digital intelligence firm based in Tel Aviv**. **Evidence You Need to See:** - **Independent security researcher Robert Heaton** published a technical breakdown showing Stylish **exfiltrating full browsing histories** to SimilarWeb’s servers. His network traffic analysis proved the extension was **stealing URLs in real-time**, not just collecting anonymous analytics. - **Google and Mozilla removed Stylish** from their official stores after the scandal, confirming its malicious behavior. - **Xinhua News Agency** reported that Stylish, owned by SimilarWeb, was pulled for “privacy violations and private data collection,” with 2 million users affected. - **Reddit’s privacy community** sounded the alarm, with users confirming the extension’s new privacy policy was a thinly veiled attempt to legitimize mass surveillance. - **Hacker News discussions** revealed that browser extension developers are frequently approached by companies offering cash for user data—Stylish was a prime example, with users’ browsing habits sold for profit. **Why This Matters:** - SimilarWeb, Stylish’s parent company, is **headquartered in Israel**, a country with a controversial reputation for digital surveillance and intelligence operations. - The extension’s permissions allow it to **“read and change all your data on all websites”**—a red flag for any privacy-conscious user. - Even after being reinstated, Stylish’s history proves it **cannot be trusted**. The open-source community abandoned it en masse, creating the safer alternative **Stylus** to escape SimilarWeb’s data dragnet. **Action Required:** - **Uninstall Stylish immediately.** It is not just a privacy risk—it is **active surveillanceware**. - Switch to **Stylus**, the community-backed fork that respects your privacy and offers the same features without the spyware. - **Never trust extensions with broad permissions**—especially those linked to data brokerage firms like SimilarWeb. **Your browsing history is not for sale. Protect yourself—remove Stylish now.**

why am i being charged!? i didnt confirm any purchases. how did you even do that

Cool. 😁 ALSO PLEASE USE EMOJIS!!!! YOU ARE SO LAZY TO USE EMOJIS!!!!! I might use Stylus if you don't. 😊

useless completely laggy cant work on even 32 gb ram and very very complex to even change a minor thing

didnt realize this was tagged "just for fun". aside from it being the biggest resource hog on a page load according to devtools, and now has eaten ALL of my styles inexplicably. so if you use this, better compulsively keep a COMPLETELY separate copy to stage on because this WILL compulsively eat ALL your styles for NO REASON. G A R B A G E AVOID AT ALL COSTS this extension SINGLE-HANDEDLY is the reason I am back on firefox and away from communistic chrome

this extension STILL steals your info. PLEASE GET RID OF IT!

Can't save styles without creating an account

Bad

dumb ahh keeps saying i have an ad blocker installed even tho i frigging uninstalled it to use this thing (made me uselessy uninstall my ad blocker)

has been broken for god knows how long, and sells your data while watching everything you send and receive

I installed this just so I could leave a review: this is a junk app that sells your data if you agreed to their terms of service. It tracks everything you do on your browser and monetizes your data. Uninstall this. From their ToS: "We need access to your browsing activity data for the websites you visit in order to provide you with available styles for such websites as well as AI inputs and outputs (including uploaded files, attachments and images) that you input and receive to provide you with our services."

bad its only work roblox on chrome

All of my styles got removed all of a sudden...

** !! ABANDON ALL HOPE THOSE WHO ENTER HERE !! ** Regarding the technical aspects of the extension itself: It loses all my styles every once in a while. Their userstyles.org portal is full of bugs. It was quite a hassle to publish my styles there. Don't get me wrong, this was once great. _Was_. In 2016 the original creator sold it, and then in Jan 2017, the new owner sold it to SimilarWeb Ltd, which is a Web Analytics company, which owns it today. They got forcibly removed off the ChromeWebStore in an emergency action and remotely uninstalled from all users browsers, because they were literally STEALING ALL USER BROWSING HISTORY without even asking anyone for permission. They literally sent every address you visited to their `api.userstyles.org` server. With all the keys in the URL and all. EVERYTHING. You got a link to reset your password, with the long unique string in the URL? They stored it. You got a link to share a document, that only a person with the link can open? They got it to their servers. You've got your search history? Clicked something on a Google Maps? Read about your medical issues on a site with some data in your url? THEY GOT EVERYTHING! And your unique ID and IP address too, since it's your browser that sends that data to their server. Read more here: https://robertheaton.com/2018/07/02/stylish-browser-extension-steals-your-internet-history/ Now, in 2025, they give you the option to agree to this absolute invasion of your privacy. That's why there is 11 colorful buttons for you to agree to their lie "We’re BEST at showing you styles for sites WHEN you visit them meaning we need access to that information. Meaning we're gonna need your agreement". Just check their website. See what they do. They are a web analytics and data company. They literally sell information about user traffic to the highest bidder. That is what they offer. They do that, and they lie to you that they need your data for something else. They also do not seem to care to fix the bugs or evolve this software. In their Privacy Policy they say they anonymize all your data. After reading the above. Do you believe them? ALTERNATIVE: There is a healthy and open source alternative fork of the old Stylish from the good days. It's called `Stylus`. See you there. === DO NOT INSTALL THIS ===

i agree with Amanuel Girma because it happend to me too.

kinda good but add more boy ones

All my local styles suddenly disappeared and I can't get them anymore... What's the point of having us create an account to apply styles if you guys can't even save them to the server?

I'm not one to 1 star projects. But the amount of spam and questionable behavior with this extension has made me rethink having it installed. I will be uninstalling it and in search for a lighter weight alternative. The only use of this extension is the website hosting the styles, which they are trying desperately to monetize. I don't have problems with monetization, and I imagine its difficult to make money off this sort of thing. But it's no longer a project of passion and is now a project to make money by any means necessary. I cannot trust the creator of this extension anymore, therefore the extension must go.

It wants me to create an account to save the custom styles. No, I won't do that. Also, it seems like it doesn't support custom properties (variables)

I do not want to subscribe to an extension, sorry. I tried saving the style I needed to change the color of visited links, which should be a default option into chrome by the way, but it asks for login. NO

Over the years, this extension has grown into multiple forms of generating profits and degrading the security of an extension that was once safe to use.

Ridiculous extension. I was looking for one that's similar to the one of Firefox to create site-specific styles for my own use only. Did the creators think once that some users don't want to share/publish their styles?

It is not working anymore on my account for lichess

Never had a worse experience with an extension in my life.

Terrible extension -- instrusive and zero privacy. Requires the user to have an account and store their code on the extenstions website, rather than just locally. This probably adds a performance hit as well, if it's phoning home on every page/site load. Pass. Just write your own bookmarklets to adjust site styles.

used to be good until they deleted all of my *personal* styles for some reason

Can only use it by logging in or through the website. No bueno.

this thing is cheeks

Why the hell do I need to create an account to save simple CSS styles? I want this to be LOCAL. Insane.

website isnt working

Cannot define variables.

its nice and stuff, but most of the themes i try using dont work. and i end up having to scroll very far to find something good. ( once i went 50 pages down trying to find a basic pink background for youtube but didnt find anything). oh also, if u even so slightly go down. theres many creepy images, im glad where blurred out but they obviously, supposed to be drawn images of adult content. even more graphic stuff id imagine if you went further.

Cant publish ANYTHING. Anytime I do it always show up with "Theres an Error with your css" When there clearly ISNT, I haven't been able to publish ANYTHING on the website because of this one dumb bug. PLEASE FIX THIS.

if your a male and not gay, you'd be highly disappointed on the themes, spent half an hour looking's for any themes, other then ANIME GIRLS AND HELLO KITTY.
