I recently switched to LibreWolf[0] and, after tweaking a few settings that were more zealous that I'd like, it has been just as good as vanilla FF. 0: https://librewolf.net/
Also always looking for someone to create a paid version of Firefox that:
- stays up to date with development of FF
- turns off all the stupid ideas
- gradually re-implement the most important parts that certain old extensions dependend on: scrapbook, scheduled website update checker (have forgotten the actual name), those kinds of things
I know many people here say: "everyone say they will pay for this or that but nobody does", but I am one of those persons who actually do pay for software that changes my life for the better or has the potential to do so.
So far I can only remember a single one (Logseq is good for now) in the last category that hasn't either collapsed in an honest way (rip sandstorm) or rewarded my early support by doing something really stupid, like typically breaking the thing that made me support them in the first place, but I guess I will continue trying.
If someone makes the thing I mention above at a reasonable price and I don't show up, please contact me, I might have missed it. (Reasonable = don't expect me to pay the same for bundling a set of patches as I pay for Jetbrains bundle or MS Office.)
