unclosable popup

There is a "Not now" link to partially hide the popup.

Upvoted you, but the substantive point surely is that Facebook is a bad web citizen for doing this. OTOH every sane person already has a (negative) opinion about Facebook and this is not the forum to air those.

Post content: In almost all of the public VR critiques I have made, I comment about aliasing. Aliasing is the technical term for when a signal is under sampled, and it shows up in many ways across graphics (and audio), but in VR this is seen most characteristically as "shimmering" imagery when you move your head around, even slightly. This doesn't need to happen! When you do everything right, the world feels rock sol…

unclosable popup

Whenever i find a site with a popup window over the content I just go to firefox's view menu and select No Page Style.

If you are mostly reading text this can be amazingly useful:

No popups/covers. Text to the width of the page. No low-contrast colors (just stark black white).

I wonder, is there a way to configure it automatically for a list of domains?

Earlier quoted context omitted.

I do this a lot of the time, too. And I believe it is ridiculous to have to do it... Yes, I'm grateful that browsers today make it easy to pwn the DOM. And it is disgusting that this is often necessary to avoid spammy website behavior. People who don't understand browser internals are forced to contend with popups and forced registration to unveil content indexed by search engines. Yep I'm looking at you Quora. Thank…

Yeah, the Google query text is an oft-broken contract. I presume there is some German word that describes the feeling of searching, seeing what you want right there, bolded in the result text, and doing a CMD-F to search for it on the page, only to hear the plaintive beep of 0/0 results.

If this happens, try hitting the google cache of the same page!

I remember reading that the Galaxy phones have trouble with pixel refresh rates. In that blacks can ghost because the nature of amoled.

The Rift and Vive also use AMOLED screens, so I don't think it's the pixel tech that's the issue. LEDs can turn on and off extremely fast. It's probably that the screen's electronics were made for power-sipping mobile devices running at most 60 FPS and not 90+ FPS gaming.

Carmack: Some times you read HN. If you are reading this, please consider writing on a blog or something neutral. It is extremely disgusting for your readers to have to log in or else...half of your screen is occupied with spam. There is people out there that prefer not to report everything they read, when, where, how, how long to a big multinational associated to the US secret services.

"Extremely disgusting" sounds like an overreaction. "Not ideal" maybe, or "not helpful to those of us who don't want to read things in Facebook for privacy or security reasons". But "extremely disgusting" is over-exaggerating the importance of the choice of medium for a text post.

Watch out, the tone police are here. Any hint of hyperbole will not be tolerated.

The best part is, facebook already has dev blogs:

https://developers.facebook.com/blog/

https://code.facebook.com/posts/

No popups, sane column widths. Yet John is still cramming blog posts into Facebook user posts.
