Did that. No change, I'm afraid.

Yes, I have left the firmware update window undisturbed and in the foreground until I gave up waiting and did something to abort.
Have tried again on a different computer, (W10, Chrome). This set up got the Bangle to stick on the message [loading] but the progress bar didn't move. I waited for 6+ minutes without any change.
Tried this both before and after deleting all apps.
(Original set up still switched straight back to the clock.)
As far as the Android/DFU method goes I am sure the watch was in bootloader mode. The screen shows
DFV start
BTN1 reboot
until the error message in the DFU app appears and the watch reloads the clock. -

Thank you both for advice. Unfortunately nothing I have tried so far has made any difference.
I'm not sure if I understood exactly what you intended by
" you long-press the button (~10 seconds or so) until you see the Bangle.js boot up showing just the Bangle.js logo. Then you could try connecting with the app loader "
but I had a go at disconnecting and reconnecting once the Bangle.js logo was showing on the watch. When I eventually managed a connection the Firmware update failed in the same manner.
I made a backup as Gamblejs suggested.
Mindful of "some app installed that is forcing Bangle.js to reload " I deleted all apps and tried the Firmware update. No change.
Then I did a Factory reset and tried to update the firmware. Same result.Life is short and none of this is quick so I've just restored from the backup for now. Any further thoughts on this mystery would be welcome.

Tried many times to update to latest firmware (espruino_2v15_banglejs2) with no success. Have tried all the methods:
- Firmware updater gets the Bangle's attention for a moment, but then the watch goes back to the clock while the App Loader page just shows a constant whirling arrow, which goes on indefinitely until I disconnect. (Same behaviour on Android and Windows (10, Edge) ).
- DFU app on Android fails showing Error: The device does not support nRF5 DFU
- IDE/Flash page reports NotFoundError: Web Bluetooth API globally disabled
If there's a setting on the Bangle that has disabled the Web Bluetooth API, I can't find it. In any case I can connect and load/update apps via the App Loader.
Grateful for any advice.

I have now managed to update the firmware, so the problem is fixed, for the moment, if not resolved.
Just so you know, this is the sequence of events. I can't see it being of much diagnostic value, though.
I tried updating the firmware via the app loader using another phone, mindful of what you said about the problem possibly being with the phone's BT, however the result was the same. The app loader was complaining that the Bootloader was old (although it was already updated to the latest version.) Tried updating that: no change.
Then I did another factory reset and updated the bootloader. After that the firmware update succeeded.
None of this makes any sense to me.
