@fnwbr And yet, here i be, revelling in the delightful UX that is my  , with all the #telemetry disabled, the #AI disabled, numerous other parameters hardened via my #userJS, with the exquisite #Sidebery & its infinitely-nestable tree-tabs & multiple #Workspaces on its LHS, & the brilliant project #FirefoxSecondSidebar with my 21 #WebPanels on its RHS. It's such a great daily browsing UX, unfazed by the last ten days of global #FUD [all the so-called nasties can be disabled, either via simple clicks in the Settings UI, or otherwise via about:config / user.js]. Herd-mentality is a ridiculous trait of humans. 🙄🤦‍♀️

 #FirefoxNightly + #Mv2 #uBO + #Sidebery + #FirefoxSecondSidebar = THE best browsing & sophisticated tab management + Web Panel UX i've ever had, easily eclipsing Vivaldi,  #Floorp,  #ZenBrowser, Waterfox, LibreWolf... ergo = 💜🥳🎉👯‍♀️

 #FirefoxNightly + #NativeVerticalTabs + #uBlockOrigin + #FirefoxSecondSidebar = Very usable already as of Feb 2025, albeit less powerful than Sidebery, ergo = 💜 🎉

@msdropbear42 I sussed it out! 🎉 Once more i can use #DoH Max Protection, ergo also #ECH, & still have fast responsive tab loading. 💃

No, that infers some smarts by me. I was not clever enough to analytically solve it, but instead i merely obstinately stumbled onto the root cause by a tedious investigative process of trial & error elimination.

Several months ago i had added this innocuous string to my #userJS in order to block being fingerprinted via HTTP/2 Fingerprinting [eg, test at https://browserleaks.com/http2]:

user_pref("network.http.http2.enabled", false);

Once i reset this to its default of true, all those many many "problematic" sites now once more load fast again. 🥳

That's cool, but my happiness is tempered by annoyance that here's yet another example where i have to trade away privacy for convenience, damnit! 😡
