Code snippets for custom keyboard shortcuts

Firefox already have very large number of keyboard shortcuts, and other addons also provide their own keyboard shortcuts, I cannot find out safe combinations for my features. So I gave up and decided to provide only APIs for other addons. Please use generic addons to customize keyboard shortcuts which can define custom actions based on scripts. Sorry.

Move focus of tabs

Firefox has its own keyboard shortcuts to move focus between tabs, but they are deactivated by default. You need to activate it by userChrome.css like:

.tabbrowser-tab {
  -moz-user-focus: normal !important;
}

By the way, Ctrl-PageUp and Ctrl-PageDown are available to focus previous/next tab by default.

Toggle show/hide the tab bar

if (gBrowser.treeStyleTab.tabbarShown) {
  gBrowser.treeStyleTab.hideTabbar();
} else {
  gBrowser.treeStyleTab.showTabbar();
}

Close the current and all descendant tabs

gBrowser.treeStyleTab.removeTabSubtree(gBrowser.selectedTab);
