test: the Firefox suite tolerates no extension error (closes #487 )

The one entry in ALLOWED_ERRORS in tests/e2e/firefox/run.js, Firefox reporting a popup promise that settled after the page unloaded, lost its cause when the site-connection buttons stopped sending with an unawaited sendMessage before closing (#275). Left in place it would also hide the same error from any other popup code that sends and then closes. The entry goes, with the code that only printed and set aside tolerated errors, and the README paragraph that described it. Model: opus-5-5

 - 2026-10-08: The browser suites no longer read a screen before the page has
  shown it ([#502](https://git.eeqj.de/sneak/AutistMask/issues/502)). Their wait
  for a screen used to pass as soon as the element laid out, which every view
  does until the page's stylesheet has applied, so an approval test could read
  the prompt's fields before the page's script had filled them. `visible()` in
  `tests/e2e/harness.js` and `waitVisible()` in `tests/e2e/firefox/driver.js`
  now also wait for the page to finish loading and for neither the element nor
  anything around it to carry the `hidden` class that `showView()` puts on every
  view but the current one. No caller changed.
 - 2026-10-08: Switching the network in Settings now tells open pages
  ([#500](https://git.eeqj.de/sneak/AutistMask/issues/500)). Once the switch is
  saved, Settings asks the background to send `chainChanged` with the new chain
  id to every open tab, through the same function an approved site request uses.
  Choosing the network already active changes nothing and sends nothing. Only
  the extension's own pages can ask for this. `tests/chainSwitchGate.test.js`
  drives the real Settings view against the background, and the Chrome suite
  checks that the test page hears both switches.
 - 2026-10-07: A site can no longer switch the wallet's network by itself
  ([#408](https://git.eeqj.de/sneak/AutistMask/issues/408)). A connected site's
  `wallet_switchEthereumChain` request for the other supported network opens a
  prompt in its own window, through the same approval machinery as the
  transaction and signature prompts, naming the site, the current network and
  the requested one. The network, its endpoints, the balances and the caches
  change, and `chainChanged` is sent, only when the user approves it; rejecting
  or closing the prompt answers 4001. One such prompt per site at a time. The
  approval window no longer shows the connection prompt while it waits for the
  background to describe the approval, because that prompt's "Allow" answers on
  the same port as the new one; `tests/approvalWindow.test.js` checks that it
  shows no screen until then. `tests/chainSwitchGate.test.js` and both browser
  suites drive the prompt.
 - 2026-10-07: Two contradictions between the documents and the code are resolved
  as ruled on [#165](https://git.eeqj.de/sneak/AutistMask/issues/165). The
  README's 1.0 non-goal now puts Ethereum mainnet and the Sepolia testnet in
  scope and other chains out of it. The injected provider's flag named after the
  other wallet stays, as an interface-compatibility flag many dApps check, and
  is written down as an exception to the rule against naming competitors in the
  README's Policies section, in `RULES.md` and in a comment beside it in
  `src/content/inpage.js`. `script/check-censored` already allows that flag only
  in that file and its built copies, so it is unchanged.
 - 2026-10-07: Two holes in what `tests/persistedFieldContract.test.js` checks
  are closed ([#379](https://git.eeqj.de/sneak/AutistMask/issues/379)). The
  check that every swept field is driven both truthy and falsy counts only
  `hostile` and `falsy` values, which the sweep drives onto every restorable
  view, and no longer a `hostileRestore` value, which reaches only the views its
  entry names; the stale index 5 moves into `hostile` for `selectedWallet` and
  `selectedAddress`, as the one value of either still truthy after the floor.
  Each `hostileRestore` entry declares whether its boot lands on its view or
  falls back to Home, and is held to it. The limits that remain, fields that
  share a slot on one boot and anything no stored record reaches by itself, are
  restated as built in the file's header and the README, which now also say
  which boots are held to where the popup lands and that a healthy profile is
  booted onto every restorable view.
 - 2026-10-07: Every password error in the popup is shown the same way
  ([#493](https://git.eeqj.de/sneak/AutistMask/issues/493)): with `showError()`
  and `hideError()` in a fixed-height error line below the password field, as
  the send confirmation and approval screens already did. The add wallet screen
  showed a missing, short or mismatched password in the flash line, and the
  private key export, recovery phrase and delete wallet screens each had a line
  of their own above the field. On the add wallet screen the line sits beside
  the Import button, so the button stays where it was at 360x600. Each line
  clears when the screen is shown again and when the password is tried again.
  The add wallet screen's other messages, such as an invalid recovery phrase, a
  duplicate wallet and the address scan, stay in the flash line.
  `tests/passwordErrorLines.test.js` drives all four screens in the popup.
 - 2026-10-07: Pre-1.0 security review of the extension
  ([#383](https://git.eeqj.de/sneak/AutistMask/issues/383)), reading the tree at
  `99292b9` for key handling, the DEBUG mode policy, and what the background
  accepts from pages, the configured RPC endpoint and the explorer, with what
  the approval screens show from it; the site permission model and storage were
  read as well. Its summary on that issue lists ten findings, each filed as its
  own issue, and all ten are fixed on `next`; one,
  [#399](https://git.eeqj.de/sneak/AutistMask/issues/399), put funds at risk.
  Three decisions it raised are still open with the owner: the Argon2id cost for
  the vault key ([#401](https://git.eeqj.de/sneak/AutistMask/issues/401)), a
  connected site switching the network with no prompt
  ([#408](https://git.eeqj.de/sneak/AutistMask/issues/408)), and `eth_sign`
  signing as a personal message
  ([#409](https://git.eeqj.de/sneak/AutistMask/issues/409)). Not covered: the
  end-to-end suites were not run, the bundled phishing blocklist and token list
  were not checked entry by entry, `ethers` and `libsodium-wrappers-sumo` were
  taken as audited, and nothing was tried against a real network with real funds
  ([#385](https://git.eeqj.de/sneak/AutistMask/issues/385)). The planned
  independent second check of each finding did not run; the findings rest on the
  reviewer's own reading of the code.
 - 2026-10-07: Stale branches pruned from `origin`
  ([#167](https://git.eeqj.de/sneak/AutistMask/issues/167)). The issue
  classifies each branch it lists, with the evidence. The eighteen still on
  `origin` that it classifies as landed, or superseded by merged pull requests,
  were deleted. `feat/message-signing` and `fix/59-transaction-view-ui-policies`
  had been deleted on 2026-09-09; both landed and stay deleted. Four are kept
  because their work is not in `next`: `fix/consistent-error-display`,
  `fix/87-consistent-error-display` and `fix/87-consistent-error-display-v2`,
  the change for [#87](https://git.eeqj.de/sneak/AutistMask/issues/87) that
  never landed, as reference for
  [#493](https://git.eeqj.de/sneak/AutistMask/issues/493); and
  `chore/token-list-enrichment`, deleted on 2026-09-09 and re-created at
  `f7a2437`, whose `scripts/` tooling waits on
  [#495](https://git.eeqj.de/sneak/AutistMask/issues/495).
 - 2026-10-07: The README says that the wallet never clears the clipboard after
  the private key or the recovery phrase is copied, and why
  ([#492](https://git.eeqj.de/sneak/AutistMask/issues/492)): the clipboard is
  the user's, clearing it would go against what they expect, and it could
  destroy something else they copied since. It is under ExportPrivKey, with a
  line under ShowRecoveryPhrase, and names the warning each password screen
  actually shows, which says nothing about the clipboard.

 - 2026-10-07: The toolbar icons in `icons/` can be redrawn in the tree

  `script/lib/icons.js`, which draws the mark and writes each PNG with node's

  drawn image. `tests/icons.test.js` requires each committed file to hold
  exactly that image, the same IHDR and every pixel. The compressed bytes are

  zlib that made the committed files did. `build.js` now copies each manifest
