@matigo Not I. I was using Netscape Navigator 3 on a G3 iMac running Mac OS 9.2.2. After about 18 months I upgraded to Jaguar (OS 10.2.6) and started using Safari. Then a glitch caused by an app that went overboard with stripping out excess language files corrupted things so Safari & Mail stopped working. This was rectified with the arrival of Tiger, but until then I used Firefox & Thunderbird, both of which were indirect spin-offs of Netscape. Then Netscape Navigator 9 came along & I used that on Tiger until they dropped support in 2008. I dabbled with SeaMonkey for a while before coming back into the Apple fold with Safari & Mail. I have 4 G4 & 2 G3 Macs in my collection & they use TenFourFox, itself a fork of Firefox for PPC Macs. It’s a slow web browser though.
These days, if something doesn’t look or work properly in Safari, I’ll use either Edge or Vivaldi as alternatives.
