I switched to Firefox and using DDG as my search engine about 2m ago and I’ll be honest I really don’t care for it. I’m trying my best but I use my phone for 100% of my browsing and not being able to set a home page sucks and with DDG searching for stuff takes significantly longer to get answers with. I search for a ton of stuff that I just need a quick answer to that when searching for Google would just show the answer instead of needing to open links and such. I’m giving it a bit more time but I’ll probably end up back with chrome.
Try the startpage search engine. It has been much better for me than DDG.
Firefox allows you to select a home page, tho? Not sure what your problem with Firefox is.
On android firefox just doesn’t perform so well as Chrome does and can seem slow and buggy.
