My go to extension, thank you so much! If it is open source, someone could help publish firefox add-on. If it is not, is it possible for you guys to publish it(PLEASE, this could help thousands of users/developers).
Please add dark mode support.
Best tool. Couldn't find on the opposing Browser. 10 out of 10
Monokai into the browser… Wonderful!
working great for me
When I click Beautify, it won't beautify the code unless I close the tab and re-open it and click Beautify a second time. Using this extension in Chrome: Version 106.0.5249.119
要自己敲代码，学学人家styleBot!!
Works as advertised and UI is not intrusive. Struggles at SUPER HUGE files (may crash) but works OK in general. For example when I tried to beautify "bundled" typescript compiler it failed midway, but that seems harsh ^^;
How to set font size
I opened .js files and nothing happened. I haven't found a way to make it work.
Add possibility to change font-size or to set own css
For me it doesn't beautifies the JS, CSS files opened from local PC. Can this be improved, please?
Doesn't work anymore on latest Chrome. Please fix it.
This extension not working right now this time.Please fix this ASAP. Thanks
Did exactly what I needed from it, awesome plugin!
Simple and easy to use. Love the beautifying Seamless Highly recommended
Nice work.
Very useful.
Exacly what I was looking for!
Wonderful Plugin, its amazing when it works- but it requires ".json" to be on the end of the document so when viewing generated jsons online its useless, I have no work around for this but if that could be fixed i would rate this 5 starts, perhaps on pages that don't end in ".json" have a button to attempt by checking to see if whats visabel is in a json format
Nice
Amazing extension. Could you support JSON by response header? (content-type: application/json)
i cant use it.
I like it. Add functionalty to set custom font name such as 'Fira Code' and font size.
Perfect
useful
很棒的插件！希望logo可以更美化一些。
Great work
方便快捷，好用
I LOVE THIS EXTENSION !!! Javascript never looked so beautiful! Thank you for your contribution. :D
Comigo não funcionou no site que estou desenvolvendo. O servidor responde que o conteúdo é JSON, mas mesmo assim não deu certo.
I'm using it for one year and I love it.
Azt vártam, hogy a forrást pl. megmutatja formázva. Ehelyett egyáltalán nem csinál semmit a plugin, csak létezik.
Está bien, pero no te deja guardar el archivo convertido. Esto ya lo hace el depurador.
请告诉我怎么用
Work perfectly!
Perfect!
Awesome Plugin saves me a lot of headache simply excellent.
Just want to say GOOD JOB, i liked it a lot
like it
