commit 75c668227b8899bcb81ec1b578eb5e48b96ff5b2
Author: Richard Pospesel <richard at torproject.org>
Date: Fri May 21 22:18:23 2021 +0200
Bug 40416: Add v2 Onion deprecation warnings
- adds new v2 deprecated warning page (js and styling) that piggy-backs
off of the existing added onion service errors
- updates identity-icon to onionWarning.svg when visiting a v2 onion site adds
warning tooltip; this warning supersedes all other identity states (including
mixed-content error)
- we determine whether to show the warning page in nsDocShell::DoURILoad()
- a new synchonous IPC method is added to ContentChild/ContentParent to determine
if the session has loaded the warning page already; worst case scenario, each
child process will need to wait on this method to return only once when visiting
a v2 onion; nothing is permanently cached with regards to this change
- an exception for the new sync method is added to sync-messages.ini (generally,
in practice adding new blocking methods is probably bad, but the minimial
overhead and frequency this method is called is worth the simpler code)
