• (2025-07-12) Another Planet’s Hell: When Google finally depreciated the "change all UI fonts" extension because of Manifest 3, I found your extension to be a perfect replacement. It's immensely helpful to me. Thank you so much.
• (2025-07-11) Luca Pozzi: Extremely useful, not perfect but the best choice now.
• (2025-06-27) Ankit Jain: Very good extension. Overrides default fonts too as per our convenience.
• (2025-06-19) arson: it worked awesomely before, i downloaded some fonts, was able to change the font for websites to those fonts! but after factory resetting my pc, it wont accept the fonts i download, and it will only display the fonts that come with the extension. </3 i have already tried restarting my pc, and uninstalling and reinstalling the extension, idk wut 2 do ):
• (2025-06-18) wolf jug: Works like a charm I Changed my Font to Comic sans it works perfectly i love it
• (2025-06-17) Ryan Small: Best font changer out there. Easy to use and so many fonts to choose from. Thank you so much! Please continue to support and make it even better!
• (2025-06-11) Da WhatTheFox: Completely breaks some websites like for example ChatGPT, which won't load if the font has been changed. I wish Google would stop messing around and would give Chrome an in-built global font changer like Firefox's.
• (2025-05-17) deaths grasp: This has everything I've ever wanted in an extension - I wanted a program that would keep my chosen fonts on every web page, and this does just that! I can finally browse the world wide with the Comic Sans MS font! Not the sort most people would choose for themselves haha, which is great because you can choose any font with this extension! Thank you for making this! 🥰
• (2025-05-13) Hoan Vo Le: The most convenient font-changing extension available.
• (2025-05-12) Feng SRIDI: Great extension! It would be great if, when I select some text and right-click, the context menu offered a “Fontonic” option to change the font of just the selected text. :)
• (2025-03-24) Logan Rutland: It's good but takes too long for the font to change sometimes.
• (2025-03-24) duuy: it work... but i wanna it change the font to all websites TwT *nvm it's in setting...
• (2025-03-22) Forest Whispers (Akiddo): Does what it says on the tin and lets you use the fonts installed on your system instead of pre-bundled ones. (EDIT: As of upgrading to a Windows 11 system, the extension only recognizes the default fonts bundled with 11, and can't recognize any I had been installed myself.) (EDIT, AGAIN: It now worked like a charm! Good on you for fixing the bug.)
• (2025-02-28) Frank Kuo: Usable, awesome!
• (2025-01-13) Asad: ChatGPT and Claude AI stops working, when Roboto Serif font is selected. A big and creepy bug....
• (2025-01-05) Nguyệt Minh: Incredibly good.
• (2025-01-04) M.L. 'BEWMIE' Wolff: Great extention! Could you please add a size changer, though? It can be a bit difficult for me to read the text on some webpages because of how small it is, depending on which font I'm using.
• (2024-12-25) Edy García: Works as intended, receives regular updates, and the developer is highly responsive.
• (2024-12-16) Stream One: My homework website got stuck on Arcade Normal. I cant get it out!
• (2024-12-07) Doruktan Erkan: A useful and well-working extension.
• (2024-11-30) 강민호: This is excellent replacement for Stylus. Works well in BlueSky and X and also in various portal websites. But doesn't work in law.go.kr
• (2024-10-06) Gia Hoàng: very gooodd!! im using windows so some microsoft website if i use previous font changer extension there is some icon missing, but this extension adaption very well!! keep going!!
• (2024-09-08) John: Needs a bold mode. I want to make my code blocks bold.
• (2024-09-05) Tariq Salim: It's an astonishing extension from every side, keep going.
• (2024-09-02) David C Margotta: This is an excellent extension. It's simple and elegant and does exactly what it's supposed to do and does it well. It's very easy to navigate. Being able to exclude various websites makes this extremely useful. I've had no issues at all since I've started using it and am very pleased with it. One thing that would be useful would be if the fonts in the list were rendered in the style that they represent. Thank you for your creation! Also: The ability to save, export, and import settings would be most welcome.
• (2024-08-12) Wasley: I thought the extension was really cool, very practical to use. Just one detail that I ended up noticing that some websites (LinkediN, Youtube, Twitch) when the extension is active, become slower because they have a large amount of text, especially if you scroll the page very quickly. I think it's worth doing a test, I use the Edge browser, I don't know if there is a more compatible browser for this extension.
• (2024-08-02) Rion: Good, but needs more features, such as Site Exemptions. I want to apply this to all the sites I visit but there are a few select sites that I don't want the font to change, but it doesn't have an exemption feature to exclude these sites. Would be great if this was implemented.
• (2024-02-26) Kritarthajyoti: Just tried it now...meets the expectations...Kudos to the developer.
• (2024-02-22) RUPESH KUMAR: Great to see this type of extension. I was looking for this kind of thing for quite a while now.
• (2024-02-22) Satyam Sajal: Works as Expected!!! 🙌
