Commits: 795b62a7 by Henry Wilkes at 2024-04-25T10:32:13+01:00 fixup! Bug 30237: Add v3 onion services client authentication prompt

Bug 42542: Remove the OnionServicesAuthPrompt class.

The class is merged into OnionAuthPrompt. This currently only works when only one tab triggers the prompt at a time.

Not linted to improve commit readability.

Bug 42542: Re-handle showing errors.

Call "_showWarning" rather than "show" when we have an error.

Do not attempt to show the prompt if we cannot determine the onion service id.

For the service id regex, use "^(.*.)?" instead of "^(.*.)*": since the ".*" is greedy, this can only ever match up to once.

Bug 42542: Reset the authentication prompt when switching between two authentication tabs.

We keep a record of which tab details are being shown in the notification popup. We reset the prompt whenever we want to show different details.

We also fetch elements and set event listeners (once) when we initialize OnionAuthPrompt. In particular, the listeners should only react to the shown details.

We also assume that elements with an ID exist in the DOM.

Bug 42542: Follow recent coding conventions.

Do not prefix variable names with "a" and use triple equality.

Bug 42542: Use "keydown" instead of deprecated "keypress".

Also, stop handling "Escape" key since it is already handled by PopupNotification.
