@sunflowerinrain I used Pale Moon for a time. It's a fork of Firefox from way back when (wouldn't be surprised if over a decade at this point) but actively developed since then. It has the usual issues of a niche product: harder to find troubleshooting info, fewer extensions available, some websites complain it's out of date, etc. That said, it worked well for me and if you want something like Firefox was historically, I think it's reasonable to try.
@khird Thank you. I didn't know of this one.
