将 Firefox 和 Thunderbird 调整为高 DPI 触摸屏显示器（视网膜）

Question

如果您使用分辨率为 3200x1600 像素的高 DPI 显示器，您可以使用系统范围的菜单和标题栏缩放来调整 Unity但 Firefox 还没有真正准备好：所有页面和图标都保持很小。

multiplication of system font increase and browser font increase makes system controls (combobox, lists, drop down lists) extremely big on many websites, where the form elements are affected by the scaling two times, so all form elements are huge (4x).

emails in Thunderbird are displayed tiny, so you have to use Ctrl++ all the time

How can I adjust Firefox and Thunderbird, so everything will look normal?

Answer 1

1. Install my Firefox-addon Zoom Menu Elements (or install this file from source on github).
   Alternative: you can manually open a new tab about:config in Firefox and search for layout.css.devPixelsPerPx set this value to 2 or 1.5 as you wish to adjust the size of the Firefox icons (source, bug report)

2. Install the Firefox-addon Fix for zoomed default-font to fix some issues with huge form elements on some pages (for ex. the login on reddit.com, ... see this question )

3. Pinch-to-zoom works out of the box (see here), for older versions the grab and drag addon for Firefox makes it possible to navigate the Internet by touch (disable it with the button in the add-on-bar when using a mouse)

4. Additionally, (but not needed) install the Firefox addon NoSquint or Default Fullzoomlevel and chose in settings: default full page zoom level 120%.

In Thunderbird you have to go for the alternative from step 1 in the advanced configuration (although I prefer not to change the overall size but use Ctrl+ and Ctrl- instead, to adjust the size of the email window)

Answer 2

我至少看起来像 Firefox 36.1，现在从 Ubuntu 中获取缩放设置。它不是动态的 - 即它在 FF 启动时读取值并设置为该值，直到您重新启动 FF。:)
