I had been a very happy Google Chrome user for years but have now switched to Slimjet on Windows.
Chrome is based on the open-source browser Chromium. In April 2016 Chromium stopped supporting Windows XP and Vista. The former was fair enough as that had been officially obsolete for two years but Vista still had a year to go. At the same time Google removed support for 32-bit Linux but Chromium didn't.
I can't say that this bothered me as most of the up-dates are only security things and other changes are rarely for the better — one of the last ones I got buggered the scrolling up, though I managed to fix it.
The problem was that after a few months Chrome wouldn't stop belly-aching about not being able to up-date itself and I couldn't find a way to shut it up. There were suggestions on the internet but most of these were for older versions or involved the use of administrative templates which the Home editions of Windows don't support.
I started looking for alternatives and settled on Slimjet. This is another Chromium derivative but has more functions, eg a build-in ad-blocker and video downloader, and the developers say they'll support XP and Vista while ever it is technically possible and 32-bit Linux for the foreseeable future. It's also easy to switch off it's up-dates. Another advantage of it is it allowing you to log into your existing Google Account making the transition from Chrome quite painless.
I used this for a couple of years but then got dis-illusioned with it. There have been no up-dates to the XP/Vista branch since early 2017 but no announcement that they've given up on it either. As I now mostly use Linux that isn't a huge problem but the main version is far from perfect. The video downloaded rarely seems to work, again this doesn't matter when there's a great program like YouTube-DL available, and the built-in add-blocker isn't a patch on uBlock origin.
The final straw for me was there being problems with version 23 about which the developers seem to be aware but unable, or unwilling, to fix. I've therefore gone over to Chromium on Linux.
