Pale Moon is the kind of browser people choose intentionally rather than by default. It appeals to users who care about browser philosophy, interface feel, and alternatives to the dominant mainstream products, and who are willing to accept that those choices need to be tested against real modern web demands.
It is especially suitable for users who already understand why they want a traditional-feeling alternative browser and who are comfortable making a practical compatibility judgment for themselves. If your main goal is maximum mainstream website certainty, Pale Moon may not be the first browser to try.
What makes it worth keeping is that it offers a genuinely different browser direction instead of functioning as a minor variation on the same dominant theme. For some users, that difference is the reason to explore it at all.
The tradeoff is that alternative browsers live or die by real compatibility. Important sites, extensions, account systems, and everyday browsing habits must all be tested in practice. A browser can be appealing in principle and still fail the workflows that matter most to you.
My recommendation is to try Pale Moon only if you have a real reason to explore a traditional alternative browser on Windows and are willing to validate it honestly. Start small, test the sites you depend on, and let practical browsing results decide whether it stays.
