Firefox ESR is based on the outdated firefox 115 engine. supermium is based on the latest chromium 121 engine and runs even on windows xp
Firefox Esr is updated regularly and is the same as the one on my Linux(s). And Supermium is not ungoogled
I use Ecosia just to annoy Duck and Gargoyle. Remember, a tree is planted every time you search! Floorp still works in Win 7 and is fully up to date with Firefox, as is Vyvfox. If you were using Ungoogled up to 109, simply move the Local and Roaming folders to your newly installed Supermium ones and you will then have Ungoogled Supermium which can be updated.
If it was that easy... Obviously is better than nothing, but google isn't just search, the sources of chromium are infested by any kind of Google services and IP addresses, as I already said the Vivaldi guys spent months cleaning UP the sources, and I guess (at least I hope) that a similar work was done in the unggogled chromium. It's just the supremium author would have done a way better job backporting the unggogled chromium rather than the plain one (with just a couple of patches which have little to do with privacy, imported from UG)
As you say, better than nothing. It´s only there for those odd occasions when a Chromium-based browser is needed. I accept some session cookies but everything is wiped when the browser closes and during the session IPv6, third party cookies, webrtc, webgl are blocked, DNS is limited, IP and SSL are obscured and there is precious little useful data for Gurgle to collect. I can live without javascript too. However, that is not what the average user wants which is what Supermium caters for.
Sorry, but recommending a browser that has Google, as a non-replacable serch engine is a preposterous joke. Why on earth would anyone make an ungoggled Browser and leave the Google search engine, which is THE basic data collecter.... An you DID recommend it as a Ff replacement, should Mozilla stop the Win7 Updates in September.
Personally I prefer to use the last supported Vivaldi release. I can live w/o being obsessed by the last update sindrome. Usually I would agree, but here Supreimium is aimed at people who aren't average Joes. Average Joe, just update his OS. People who use Supreimum is usually, the same people who refuse to update to W8.1/W10 because "privacy reasons", which I find really funny. It's like fighting because the syphilis, then catching the AIDS voluntarily...
I was not recommending anything - just correcting your inaccurate information: the Gargoyle search engine can be deleted and Supermium is only of use to those who need a Chromium-based browser in pre-WinX systems. If you tighten it up as I suggested then it will serve its purpose. Otherwise use one of the Mozilla forks which still work: Floorp, Mullvad, Vyvfox or Waterfox. If Mozilla pulls the plug, there is MyPal, New Moon and Serpent 52 which will continue to work as that is their purpose. Opera 12, Otter and Falkon work as do non-updated recent versions of Iridium, LibreWolf and Vivaldi. There´s plenty of choice.
