1. Creating a theme that works for Firefox 4 on Mac OS X. Create a new directory (for example, MyTheme). Inside that, create another new directory chrome.
2. Mozilla today launched Firefox 62 web browser for macOS, bringing variable fonts support and a new automatic dark theme to Mac desktops. By introducing a dark theme to the browser, Mozilla is.

Mac OS X users of Firefox who still use these older versions of the Mac OS X operating system will be able to use Firefox ESR for another year before support runs out. It is unclear if and how other Firefox channel installations, e.g. Firefox Nightly or Beta, are affected by Mozilla's decision to end support. There is another clever feature inside Firefox that clears out your extensions and themes, plus resets all the preferences to default, but keeps your personal information intact, including bookmarks, history, open tabs and windows, saved passwords, autofill info, and even cookies.

• 1Mac Theme/UI Refresh
  • 1.1Update to Visual Styling

The overall design changes for Firefox 3.7 on Mac are mostly the same as what is being proposed for Windows. Structurally they are very similar with a notable exception:

• The Menu Bar: The Menubar on Mac is different from its counterpart on Windows. There is no system wide push to phase it out and it is an integral platform UI element.
• App Button: Since the Menubar is not being changed this button will not be on by default if available at all.

In addition to the structural changes already proposed the Mac theme is primarily focusing on visual design changes.

Update to Visual Styling

One goal of this visual refresh is an increased amount of cross platform consistency where it makes sense. This means we have tried to incorporate similar(or even identical) shapes for items such as buttons, glyphs and tabs. The changes to make these things fit in are how they are styled and textured.

Proposed changes from the current Mac theme:

• Button Shape: Using rounded rectangles instead of the curved-end buttons found in 3.0–3.6. This will match the native button shape as well as the shape planned for Windows.
• Button Texture: Slight deviation from the current texture. Adding a slight gloss and edge highlight for some added dimension/depth.
• Removal of Bookmark Bar Texture: Removal of the glossy bookmarks bar texture for less visual complexity and more streamlined look.
• Tab Shape: Slightly more defined tabs. Also rounded edges connecting to the toolbar.
• LocationBar Shape: Use a rounded rectangle LocationBar instead of a curved-edge. This creates a visual distinction between the LocationBar and the SearchBar even though the LocationBar is still technically a search field.

Differences from the Windows theme:

• Back/Foward Arrows: Use system standard back/forward glyph shapes instead of the Windows arrow with a tail.
• Hanging Tabs: Instead of the tab attached webpage style seen in Windows we retain the hanging tabs approach from 3.0. This is the de facto system standard (e.g. Safari, Terminal, most 3rd part apps with tabs).
• No Icons on the Bookmarks Bar: This reduces icon overload and matches Safari.
