A tab you switch away from is frozen (page lifecycle "frozen": no JS,
timers, network callbacks or media) one second later and thawed the moment
it is shown again. Right-click a tab → "Keep running in background" exempts
it (music, calls, dashboards); the strip marks it ▶. Dormant restored tabs
and tabs waiting on a page dialog are never frozen. Settings › Performance ›
"Stop tabs in the background" (on by default) turns it off. Freezing uses
the per-tab debugger applyFingerprint already keeps attached; Chromium only
freezes hidden pages.
The downloads, site-info and engine-picker popups close when focus moves
elsewhere in the window or to another app; the toolbar click that caused
that does not reopen them. Focus only moves into a popup while the window
is active — focusing it from the background blurs the window and closed the
popup it had just opened.
Also fixes a bug in the lazy overlays: isLoading() is still true while
did-finish-load is delivered, so a first show waited out the 4 s timeout
before appearing. Finished loads are now recorded explicitly.
The browser — the consumer face of the stack. Native .bch support with the
resolver built in, so a user installs one app instead of modifying their
operating system. Named for the thread through the labyrinth: the chain is the
thread.
Scope
Electron shell (Chromium engine, no forking): tabs, address bar, history.
In-process .bch resolution — no system daemon, no NRPT, no OS
trust-store changes; reuses bns.js from the BNS repo as a library.
Record handling: h render, ip connect, p/s3 via in-app gateway,
u redirect.
TLS via cert-verify hook (Electron setCertificateVerifyProc) against the
BNS root / on-chain tls fingerprints — no OS store touched.
Provenance indicator: shows whether a page came from the chain / Sia / a
direct server, with NFT category and record type — the decentralized padlock.
Status: not started
Build it in its own session/repo. The ready-to-paste brief is
BROWSER-PROMPT.md (a reference copy in this folder; canonical source is
D:\Dev\NameCoin\BROWSER-PROMPT.md — if they diverge, NameCoin wins). It points
here and reuses the resolver core. theseus.bch is registered and should
eventually serve the browser's own homepage over the protocol it implements.
