Vergrößern geht übrigens auch ohne Extension:
Dazu die userChrome.css im Profile/Chrome - Verzeichnis öffnen bzw. neu anlegen falls noch nicht vorhanden.
Dort dann folgenden Code einfügen:
/* Search box verbreitern(In diesem Fall 400 Pixel Breite) */
#searchbar {
-moz-box-flex: 400 !important;
}
#search-container {
-moz-box-flex: 400 !important;
}
Noch was ohne Extension:
Disable Other JavaScript Window Features
Firefox has a few options that allow you to decide what scripts can and can not do with windows. These options are available from Tools > Options > Web Features > Advanced. However, this list of options doesn't cover them all. There are some other useful options which can be applied by adding the following code to your user.js file:
// More DOM/JavaScript options
// Make sure all pop-up windows are resizable:
user_pref("dom.disable_window_open_feature.resizable", true);
// Make sure all pop-up windows are minimizable:
user_pref("dom.disable_window_open_feature.minimizable", true);
// Always display the menu in pop-up windows:
user_pref("dom.disable_window_open_feature.menubar", true);
// Always display the Navigation Toolbar in pop-up windows:
user_pref("dom.disable_window_open_feature.location", true);
// Prevent sites from disabling scrollbars:
user_pref("dom.disable_window_open_feature.scrollbars", true);
