Symptom: on any machine that had been through a series of installs, one or
more older "BNS Local Root CA" certs from earlier builds could accumulate in
LocalMachine\Root -- an unconstrained root from before 2026-07, or a rotated
one -- and every install added the current constrained root ALONGSIDE the
stale ones. Two certs with the same Subject-DN defeat browser chain-builders:
Chromium/Edge/Firefox pick one candidate and refuse to try the others, so
every .bch site failed with ERR_CERT_AUTHORITY_INVALID / SEC_ERROR_BAD_SIGNATURE
in every browser EXCEPT Theseus (which trusts the on-chain tls fingerprint
directly, not the machine store).
Reproduced on the dev box: two BNS Local Root CAs present (thumbprints
EB5DBE98... constrained + 23538FD7... unconstrained), DNS answered correctly,
strict Invoke-WebRequest to https://coinspectrum.bch/ failed. Removing the
stale one and re-running the chain-build restored HTTPS 200.
Fix (install.ps1):
- Before Add(imported), enumerate the store and $store.Remove() every
"BNS Local Root CA" whose thumbprint differs from the one we're about
to trust. Post-condition: exactly one BNS root remains after install.
Fix (uninstall.ps1):
- Switched from `Get-ChildItem Cert:\LocalMachine\Root` to X509Store direct.
The Cert: PSDrive is not always loaded in Inno's [UninstallRun] -NoProfile
context, so uninstall could silently leave the CA behind on the store side
even while it removed everything else.
Verified end-to-end on this box: 0.1.4 upgrade over 0.1.3 finished cleanly,
BNS Resolver Daemon Running, 127.0.0.1:53 open, exactly one BNS Local Root
CA in the machine store, strict HTTPS to https://coinspectrum.bch/ returned
200 (506,997 bytes) with X509Chain.Build ok=true leaf -> BNS root.

- Security popover redesigned to resemble Firefox's site-info panel:
lock/shield hero, "Connection secure" status, host, plain-language
subtitle, and a details grid; the overlay view auto-sizes to content.
- Search-engine picker returned to the toolbar with an "Add / edit engines…"
entry that opens Settings; added Ecosia, Mojeek, Presearch.
- Custom search engines: add (name + URL template with %s) / remove in
Settings > General; used by address-bar search.
- Address-bar placeholder: "Ask a search engine or enter web address".
