@Ken:- Edge is definitely 64-bit only, I'm afraid. Even M$ - who clung to 32-bit OSs way past the point of sheer cussedness - will, to the best of my knowledge, be dropping 32-bit versions of Windows very shortly, IF they haven't done so already.
32-bit browsers are becoming a rarity. The two remaining Chromium-based browsers that still supported 32-bit were Iron & Slimjet.....and as you well know, the end of the road came for those sometime last year. Vivaldi, IIRC, pulled the plug a year prior to that.
Only 'zilla-based browsers now support 32-bit-only hardware under Linux; primarily Firefox - both mainline 'Quantum' & ESR - and to a lesser degree, PaleMoon, though these are not 'official' builds, rather 3rd-party builds (thanks, Steve Pusser!) which have been given official sanction by Moonchild Productions.

Understand; next year will mark the 20th anniversary of the official arrival of 64-bit hardware onto the computing scene. Yes, that's right; the very first commercially-viable - and successful - 64-bit CPU was launched in September 2003.....the immortal AMD Athlon 64, which powered my own recently-expired older rig. It would have been legally-allowed to purchase its own booze as of last year!

There's still a ton of second-hand 32-bit hardware circulating round the second-hand and reseller's market-places. TBH, nobody wants it now. Where's the point in buying a type of computer hardware that is rapidly losing software support from all directions? I mean, you can pick up halfway-decent Dell Latitudes with a 64-bit Core2Duo for around £50-60 on many auction and reseller sites like Gumtree or eBay. I think the Pentium 4s were probably pretty much the last gasp of the peak of 32-bit dominance; you're there talking about 20-25 years ago. It's why I've finally retired the anciente Dell lappie; if I personally run an OS, it's got to be able to get online. Any browser pegs the P4 at 100%, and waiting for anything to actually happen is like watching paint dry. It's painful.
The Inspiron's been a faithful companion for nearly 19 years, but she's had her day. But it pisses me off no end, because everything still functions fully, 100%. And I just don't see the point in sending stuff that works to the tip.
@rockedge :-
32-bit Firefox still functions 100%, and is still being produced.....it's available from the FF release site:-

The crunch-point is whether any 32-bit CPU/system has actually got the grunt to meet its demands. That's where things rapidly go to hell in a hand-basket..... It's a paradoxical, and ironically sad fact, that it's only in recent years that hardware now has the "grunt" to really let 32-bit browsers shine.
As for the loss of DRM ability on 32-bit, that's simple. Despite the fact that there's several DRM technologies out there, Google's proprietary WideVine technology gained 100% market dominance, and everybody coded their browsers to use it. Then 5 years ago, Google made the decision (and announced that fact) to drop 32-bit WideVine support by the end of May 2021. They DID give everybody fair warning. And.....it happened. And is now history. And was hardly unexpected, given that Big Brother have been pushing for everyone to move to 64-bit for at least the last 8 years.....
