Walkthrough

The changes refactor the address toolbar's page action stack naming convention, add accessibility identifiers for UI testing across multiple browser view controllers, and fix constraint logic and keyboard handling bugs in toolbar layout code.

Changes

Cohort / File(s) Summary
Toolbar Stack Refactoring
BrowserKit/Sources/ToolbarKit/AddressToolbar/BrowserAddressToolbar.swift
Renames internal pageActionStack to trailingPageActionStack throughout the file. Updates all setup, layout, configuration, visibility, spacing, and constraint logic to reference the renamed stack. No public API changes.
Accessibility Infrastructure
firefox-ios/Client/Application/AccessibilityIdentifiers.swift, firefox-ios/Client/Frontend/Browser/BrowserViewController/Views/BrowserViewController.swift
Adds six new accessibility identifier constants (overKeyboardContainer, headerContainer, bottomContainer, bottomContentStackView, contentContainer, statusBarOverlay). Updates BrowserViewController initialization code to assign these identifiers to corresponding UI elements.
Toolbar Constraint & Keyboard Fixes
firefox-ios/Client/Frontend/Browser/Toolbars/AddressToolbarContainer.swift
Fixes typo in variable name (shoudShowKeyboardshouldShowKeyboard). Corrects layout constraint to reference rightSkeletonAddressBar instead of leftSkeletonAddressBar. Refactors skeleton address bar setup with guard-based early return.

328-333: Fix animation stack list to include trailingPageActionStack.

trailingPageActionStack is missing from stacks, and browserActionStack is duplicated. Newly added trailing actions can stay alpha=0 and never appear.

137-139: Accessibility identifiers wired cleanly.

Nice, this improves UI testing and accessibility tooling without changing behavior.

Also applies to: 149-151, 155-157, 179-188, 191-193

firefox-ios/Client/Application/AccessibilityIdentifiers.swift (1)

64-73: New accessibility identifiers look good.

Clear, consistent naming for UI testing.

firefox-ios/Client/Frontend/Browser/Toolbars/AddressToolbarContainer.swift (2)

223-235: LGTM for keyboard accessory state gating.
The rename and guard logic read cleanly and preserve the dispatch throttling.


461-477: LGTM for the early-return guard in skeleton layout.
The guard-based structure keeps the constraints scoped to the swiping-tabs feature flag.

⚠️ Potential issue | 🟡 Minor

Divider visibility ignores trailing page actions.

hasPageActions only checks the leading stack. If trailing actions exist but leading is empty, the divider stays hidden.

🐛 Proposed fix
-        let hasPageActions = !leadingPageActionStack.arrangedSubviews.isEmpty
+        let hasPageActions = !leadingPageActionStack.arrangedSubviews.isEmpty ||
+                             !trailingPageActionStack.arrangedSubviews.isEmpty

⚠️ Potential issue | 🟠 Major

Fix inverted toolbar constraints (leading/trailing pinned to the same right skeleton).
toolbar.leadingAnchor is now tied to rightSkeletonAddressBar.trailingAnchor while toolbar.trailingAnchor is tied to rightSkeletonAddressBar.leadingAnchor, which creates an unsatisfiable/inverted width. The leading anchor should remain tied to the left skeleton’s trailing edge.

🐛 Proposed fix
-            toolbar.leadingAnchor.constraint(equalTo: rightSkeletonAddressBar.trailingAnchor).isActive = true
+            toolbar.leadingAnchor.constraint(equalTo: leftSkeletonAddressBar.trailingAnchor).isActive = true
