クソ以外の何物でも無い。
今まで設定していたユーザーCSSが全然効かないうえに、再度管理画面から中身をチェックしたら、コードが消えてるじゃねえか。
欠陥品も良いとこだ。

Works well but it needs to be integrated with userstyles page. something like additional button or clicking "install on stylish" will add it to stylus.

Edit: t could be another addon interfering? Yes. Stylus. but with new version I am facing less issues. Git is bookmarked.

管理画面が開けるようになった。
thx

All is well, but there is one but a drawback.
I noticed that when I go to the page youtube it freezes, it can get wrong that the page does not respond.
waiting for fixation

Awesome!

57.0へのアップデート後、使いにくくなったStylishを止めて、このStylusを使用した。以前のStylish同様の機能を持ちながら、それ以上の使いやすさを実現している。もうStylishに戻ることはないだろう。

各種項目は日本語化され、内容は適切でわかりやすい。特に、何か期待する動作と違うことになりそうなとき、その理由が表示されるのがとても良い。次に何をすればいいのか一目瞭然だからだ。

Stylusは、ユーザーCSSを駆使する人たちにとってより良い選択となるだろう。

The UI is kind of ugly and some options are not entirely clear, but it does the job. Thanks! Would be awesome if you guys could lobby Firefox for an API to change userChrome.css via Stylus.

New to all this. Tried installing Stylish 3 on FF 57. Install repeatedly fails with database error, and could not find any way to resolve this.
Installed Stylus, install went perfectly, created a new theme using CSS copied from userstyles.org. Worked perfectly first time. Excellent so far!

Non-intrusive alternative to Stylish that actually works.

Does not work on Firefox 56 for Android.

awesome replacement for stylish!!! and the one that keeps compatibility with firefox 52 and windows xp (this is my grandpa's pc and it's too old for windows 7 onwards)
please don't ever sell our information

- PS: for the people looking for custom and/or dark firefox options and about pages just install a theme that changes that, I have FT Deep Dark theme and "my favolours" style for a dark and non-eyehurting web experience
- PS2: One thing I liked from old stylish is that it had omnipresent application of global themes. With stylus sometimes is visible a white screen for a second after clicking a link. Also sites like this one and firefox start page are not included in stylus for global themes. If you could fix that it would be awesome. Thanks for your work

I am getting "This add-on requires a newer version of Firefox (at least version 55.0). You are using Firefox 52.0." But I am actually using Firefox 57.0! What sorcery is this?

Edit:

I downloaded version 1.1.4.2 of Stylus and was then able to update to version 1.5 from Firefox's add-on manager. Stylus add-on page still says my version of Firefox is 52.0, though.

Stylish for the free web. Fan-fucking-tastic.

Please enable Firefox Sync to transfer styles between computers :)
