I use uMatrix with very restrictive default settings. These[0]: https://smichel.me/hn/umatrix-global.png https://smichel.me/hn/umatrix-global.png When a page doesn't work, and I care enough to un-break it, I will first try enabling just js. If that doesn't work, I'll add XHRs, too. So, I can say with confidence that there are a good deal of sites that fall into both camps. I cannot say the ratio with confidence, but there are enough sites that work enough with just js that I choose not to enable XHRs. Here are a few examples: - Kotlin documentation gets collapsing menus and nicer code formatting: https://kotlinlang.org/docs/reference/visibility-modifiers.html https://kotlinlang.org/docs/reference/visibility-modifiers.h... - This person's blog gets inline/popup footnotes and, er, a functional "hard mode" (top right): https://mango.pdf.zone/finding-former-australian-prime-minister-tony-abbotts-passport-number-on-instagram https://mango.pdf.zone/finding-former-australian-prime-minis... - https://represent.us/ https://represent.us/ renders about halfway without js. The final example is the most relevant to this conversation, I think. Especially, there is a phenomenon, common enough that I've noticed it as a pattern of sites that display images with js (and sometimes content), and don't require XHRs to do so. ---------- Looking through my history to find these examples, two things become clear (about the sites I visit; I don't claim my browsing is representative): 1. Regardless of whether they also need XHRs, sites that require JS fall overwhelmingly into one of two categories: either I use them regularly and they're already on my saved whitelist (eg, YouTube), or I decide that I didn't care enough about them to bother enabling javascript 2. Yes, you're right; most sites that require js, also require XHRs. However, if we limit ourselves to the subset of sites above that I haven't whitelisted and don't want to walk away from — ie, the ones where I'm actually fiddling with uMatrix — it's somewhere around 50%. In conclusion, I think the functionality is useful and should not be axed, but it's probably a also good idea to have a simplified mode like you suggest: combining js, xhr, and other into one column. Maybe also removes the "cookies" column — most browsers have built-in preferences for those; 3rd party cookies almost never have to be unblocked; and I don't know (m)any people besides me who block 1st party cookies by default. [0]: Here's what that looks like when actually applied to the page. The keen observer will note that scripts are only temporarily enabled (I do this only when I want to use the collapse functionality). This (enable it when I want it) is a common browsing pattern of mine on sites that do progressive enhancement. https://smichel.me/hn/umatrix-hn.png https://smichel.me/hn/umatrix-hn.png
