If you wanted to point to the year where they've been the best financed they've ever been and where they've had the most resources invested into browser development they ever have, that year would be 2026. Only to be exceeded by 2027 and then 2028, 2029 and beyond.
At a bare minimum, their endowment gives them probably a two to three year firewall in the event that their funding is cut off, which it hasn't been. I also thought the accusation was supposed to be the other way around, namely that we all knew they were going to get funded into perpetuity as controlled opposition.
With Librewolf I can get proper WebGL, full UBo -with the AI blocklist too to avoid all the slop- and Bypass Paywall Clean from Giflic or whatever was called. Yeah, eh, y local newspaper won't mainly get adverts' money but the rest of local company ads show up well even with UBo/BPC, so they get some money after all.
On RAM usage, Librewolf it's far lighter on the long term and it doesn't ping back as Firefox, and many times less than Chrom* based browsers where, I repeat, Chrome based browsers don't allow UBo any more even if installed from their Github repo enforcing some about:flags variables related to legacy extension support.
The web today without UBo it's unmanageable. Popus, more than the ones from 2003, malware disguised as ads even on mainstream, safe sites, and all of these running zillions of cookies and trackers converting your -otherwise perfectly usable- old amd64 Celeron machine with 2GB of RAM into some crawling Pentium III with 256MB of RAM. With LibreWolf and UBo I could even test Yandex Maps with Prypiat and the like and InstantStreetView too. No slowdowns, no OpenGL >= 3.3/Vulkan video card required, and no need to own a 8GB machine.
HN developers there without UBo if they depend on the web for documentation they are bit screwed if they use Chrom* based browsers, sorry. Half of the resources for their machines coudn't be used, you know for IDE's, compilers, virtual machines/containers and whatnot. And, yes, I know about ZRAM under GNU/Linux, and just imagine how many tasks would anyone accomplish with a ZRAM compressed chunk (~1/3 of the physical RAM), a light desktop environment as Lumina/LXQT and a non-Chrom* browser blocking all pests. Up to 3X more tasks in the same machine. No need to waste money on upgrades, and compilng cycles are cut down for the good.
