Does Dark Reader work good on HN for you? Because it's not for me.

Edit: I just remembered I've been using an extension called "Hacker News Enhancement Suite" to enhance the layout of HN, and after disabling it, Dark Reader worked so I think that extension was somehow interfering with Dark Reader.

That extension looks to be a complete restyle of HN, which is probably why it was not interacting well with Dark Reader. I don't know what features you're looking for in the extension, but there's another called Refine Hacker News which adds features but doesn't change the styling. It does work well with Dark Reader.

I love Dark Reader but have it disabled on HN.

I use "Hacker News Readable Dark" under Stylus and this site looks fantastic.

That, and for Safari on iOS I bought Noir. Works like a charm and cannot miss it. Noir and automatic reader mode is actually a pleasant way to browse the web (although I often disable reader mode because it gobbles up images etc.).

Have you kicked Hyperweb’s tires? Not sure how much functionality you need, happy customer.

Haven't heard of it (new to iOS). Looks fine, although at home I have DNS ad blocking, and I'm not sure how the auto-clicking feature works. I wouldn't want to automatically accept all cookies; I always manually reject everything, and until now I thought that wasn't possible automatically (it's very heterogeneous).

I don't install extensions that require all my browsing data, but I was tempted by Dark Reader for a moment.

If anyone knows a similar solution that doesn't require such an extreme, I'd like to hear about it..

I use the built-in darkmode settings in qutebrowser [1], which work surprisingly well for most websites, but certainly not perfect. My impression is that the implementation is mainly in Qt, or Qt Webengine, so the same functionality may be available in other browsers with the same engine. The documentation also mentions Chromium, so perhaps equivalent settings are available there. (That said, qutebrowser is great.)

Anyway, my vague understanding of what is does is that it inverts all colors on the wrong side of a user-configurable brightness threshold (e.g. backgrounds that are too bright are inverted, and text that is too dark is inverted). This can make website colorschemes quite different, but most of the websites I visit regularly are still still readable, and often still reasonably nice-looking, despite having inverted colors.

The relevant part of my config file looks like this:

  # This requests the dark version of the website if it is available. Generally when this
  # works, I guess brightness-based the color inversion doesn't happen.
  c.colors.webpage.preferred_color_scheme = 'dark'
  c.colors.webpage.darkmode.algorithm = 'lightness-cielab'
  c.colors.webpage.darkmode.contrast = 0.0
  c.colors.webpage.darkmode.enabled = True
  c.colors.webpage.darkmode.grayscale.all = False
  c.colors.webpage.darkmode.grayscale.images = 0.0
  c.colors.webpage.darkmode.policy.images = 'smart'
  c.colors.webpage.darkmode.policy.page = 'smart'
  c.colors.webpage.darkmode.threshold.background = 128
  c.colors.webpage.darkmode.threshold.text = 128 

I haven't spent any time tweaking the threshold values, but maybe some tweaking would make it even better.

Interesting, thank you!

Any extension that injects JS on the page on arbitrary sites, is marked as having access to all data—because it does. But it's the only way that interface-modifying extensions can work, if you want them kick in automatically.

It'd be nice if there was a browser permission along the lines of "this extension adds a static asset to every page" or "this extension can _write_ but can not _read_ the page".

To add static CSS styles, you need to know the structure of the HTML in advance, which the extension doesn't. And to modify the DOM—even to add styles on it—you need to traverse it, i.e. read. Plus, the whole job of the extension is probably to figure out what styles are on the page already and how they can be fiddled into the darkness.

I kinda get your point, but I feel like there needs to be a middle ground between tweaking some colors and granting full access to my passwords.

Like, there is simply no way that is not a solvable issue.

To redefine styling in CSS, you need to know the structure of the HTML for a specific site or page. If you don't know it, you need JS to poke in HTML, fiddle with the styles and hope that it works out alright.

Dark Reader inspired me to write a similar one for myself: https://chrome.google.com/webstore/detail/obscura/nhlkgnilpm...

Where Dark Reader is full-featured, mine is minimal. It adds a translucent tinted div overlay on every page, with mix-blend-mode:multiply to make the text come out a little sharper. No themes or querying page elements.

You can audit the code yourself if you want, it's only 58 lines of JS across 2 files:

    // content.js (this runs on every page):
    'use strict';
    const C=chrome, d=document.createElement('div'),
        update=(o={})=>{
            if('tog' in o){d.style.height = (o.tog.newValue | o.tog)+'00%';}
            if('color' in o){d.style.backgroundColor = o.color.newValue || o.color;}
        };

    d.style='mix-blend-mode:multiply; z-index:2147483647; position:fixed; width:100%; top:0; right:0; pointer-events:none;';
    document.documentElement.insertBefore(d, document.documentElement.firstChild);
    C.storage.local.get(null, update);
    C.runtime.onMessage.addListener(update);
    C.storage.onChanged.addListener(update);


    // popup.js:
    'use strict';
    let XY=[150,40];
    const C=chrome, S=C.storage.local,
        send=x=>C.tabs.query({active:true,currentWindow:true}, t=>C.tabs.sendMessage(t[0].id, x)),
        torgba=x=>`rgba(${x[0]}, ${x[1]}, ${x[2]}, ${x[3]/255})`,
        dropper=(x,y)=>torgba(c.getImageData(x,y,1,1).data),
        target=(x,y)=>{c.fillStyle = 'black'; c.beginPath(); c.arc(x,y,30,0,Math.PI*2,true); c.stroke();},
        touch_xy=t=>{const r=c.canvas.getBoundingClientRect(), f=(x,ox,r)=>Math.floor(Math.min(Math.max(x,ox+1),r-1)-ox);
                    return[f(t.pageX, r.left, r.right), f(t.pageY, r.top, r.bottom)];},
        init_c=()=>{
            c.clearRect(0,0,c.canvas.width,c.canvas.height);
            c.canvas.style.backgroundColor='white';
            const g1=c.createLinearGradient(0, 0, c.canvas.width, 0), // horiz, hue
                    g2=c.createLinearGradient(0, 0, 0, c.canvas.height);  // vert, lightness
            g1.addColorStop(0.2,'rgba(255,120,120,0)');
            g1.addColorStop(1,'rgba(255,130,70,0.99)');
            g2.addColorStop(0,'rgba(0,0,0,0)');
            g2.addColorStop(1,'rgba(0,0,0,0.8)');
            c.fillStyle = g1; c.fillRect(0,0,c.canvas.width,c.canvas.height);
            c.fillStyle = g2; c.fillRect(0,0,c.canvas.width,c.canvas.height);},
        xy_send=(xy)=>{init_c(); target(...xy); send({xy, color:dropper(...xy)});},
        xy_save=(xy)=>{init_c(); target(...xy); S.set({xy, color:dropper(...xy)});},
        c=document.getElementById('c').getContext('2d'),
        tog=document.getElementById('tog');

    window.addEventListener('load',()=>{
        S.get(null, o=>{
            if('tog' in o){tog.checked = o.tog;} else {S.set({tog:tog.checked});}
            if('xy' in o){init_c(); target(...o.xy); XY=o.xy;} else {S.set({xy:XY});} // color's xy coords in canvas
            if(!('color' in o)){S.set({color:dropper(...XY)});} // hardcoded default xy location
        });
        tog.addEventListener('change', x=>{S.set({tog:tog.checked});});
        c.canvas.addEventListener('mousemove', x=>{if(x.buttons!==1){return;} xy_send([x.offsetX, x.offsetY]);});
        c.canvas.addEventListener('mouseup', x=>xy_save([x.offsetX, x.offsetY]));
        c.canvas.addEventListener('touchmove', x=>xy_send(touch_xy(x.targetTouches[0])));
        c.canvas.addEventListener('touchend', x=>xy_save(touch_xy(x.changedTouches[0])));
    });
    window.addEventListener('keydown', e=>{
        if(e.key==='x'){tog.checked = !tog.checked; S.set({tog:tog.checked});}
    });

Cool, thank you!

seems nice, would love live reloading

To me dark mode makes eye strain worse. I much prefer a deep red tint on light mode than dark mode with no red. Also dark with red tint is quite difficult.

I feel like during the day most things are bright/cool with darkness as the contrast. Text on paper. Also as much as dark mode has become an option, it's impossible to go an entire day without experiencing a light theme and the switching of light to dark or dark to light for me is worse than whatever problems each theme has. Point being it's easier to only use light than only use dark.

Anyway dark mode without red tint isn't really helping with the blue light problem? Especially if the media you're looking at is mixed with e.g. images of daylight.

I really liked Dark Reader at first but over time I ran into too many edge cases and bad themes across the web where I felt like the time tweaking sites wasn't worth the effort any more. I had to turn it off for so many sites I eventually uninstalled it. Now I'll only use dark mode if the site natively supports it (more and more are lately), otherwise I'm not crazy about playing cat mouse game hacking dark mode into sites that don't support it.

Dark Reader has 4 different themes. The default one does the job maybe 80% of the time, but whenever I encounter a site that looks a little wonky, I just click through the other 3 themes and one of them usually works much better. Then, I save that as the default theme for the site.

Same here. I can't use the web without Dark Reader anymore. It's not like other dark mode extensions that just apply a generic "make everything this much darker" filter. It seems to take a lot more into account when it's rendering the page. It usually looks pretty nice. Almost like a native dark mode.

Sometimes it leaves black-on-dark for icons and such, but that's negligible, and definitely a good trade-off to my eyes being drained.

Side note: Maps is surprisingly good with Dark Reader!

Just installed this on your recommendation. I felt my eyes relax as the screen changed colors. I'm hoping this is a long term add. Thanks!
