- 🔨 Improve style of highlighted URL option in address bar popover
- 🐛 Fix unreadable highlighted URL option in address bar popover when starting Firefox with the new system theme method

🐛 Bugfix: For the system theme method, Zenfox will now correctly apply your system theme from firefox start

🌟 Add a new method: Follow global system theme! This means Zenfox can switch automatically between dark and light themes based on when your system changes theme – Windows, Linux or MacOS.

(Thanks to @glward on Github for the feature request and help testing!)

- The selected text color in the address bar now updates when you change your accent color
- Use subtle sidebar border colors
- Invert sidebar color scheme on light theme

- Theme `toolbar_field_highlight` as the chosen accent
- Return to old style for `popup_highlight_text` since new one was not as planned

- Follow the latest Firefox API for theming, preparing for version 70
- Theme the popup highlight texts

Firefox has been busy adding new APIs to theme even more parts of the interface, and so Zenfox is updating to keep up. Enjoy the new theming on:

- tab text
- toolbar
- popups
- sidebar

* Bugfix: Time method now properly detects change in your local time, so it'll change from dark to light (or reverse) automatically now, without any other action needed

- Fixed settings page opening on *every* startup — now only opens on first startup after install
- Default options are selected more consistently internally, and also on the settings page
- Added message on settings page to select 'default' theme as Firefox theme, as ZenFox works on top of that (using 'dark' or maybe 'light' instead can cause inconsistencies)

Features:
- settings are saved across browser restart
- manual method: last used theme is applied upon browser restart
- default method and accent colors are now provided for immediate use
- notification added on settings page to indicate successful save

Bug fixes:
(see GitHub… some new ones were introduced and fixed with the above features, and some longstanding but obscure bugs were also fixed)

- open settings page on install
- change function and title of toolbar button based on selected method

- Re-ordering settings page for clarity
- There are no default settings on start-up anymore, internally or on the settings page — this was done because on first startup, for example, the method would say manual but pressing the toolbar button would do nothing. It was necessary to save settings although manual already appeared selected. It won't appear selected any more.

- Choose your own accent color, for tab line, loading and icon attention
- Time method: choose your own times
- Weather method added
- Weather method: add own co-ordinates and API key

Complete rebase of all the code, and now the foundation is truly there to add many more methods. Now, you can change the method between 6am/pm switches, and a manual toggle fro the toolbar icon. More to come!
