## Дополнения

Firefox славится своей большой библиотекой дополнений, которые могут быть использованы как для добавления нового функционала, так и для изменения существующего. Новые дополнения можно найти с помощью инструмента "Дополнения" в самом Firefox.

См. также дополнений, отсортированный по популярности.

## Плагины

См: Browser Plugins

Чтобы узнать, какие плагины установлены, введите:

    about:plugins

в адресную строку Firefox или перейдите на страницу Дополнения через меню Инструменты и выберите вкладку Плагины.

### Интеграция с GNOME

Установите firefox-extension-gnome-keyring-git из AUR для интеграции Firefox 3.6.x с Gnome-keyring.

Также вы можете установить firefox-extension-firefoxnotify-git, чтобы получить интеграцию с уведомлениями libnotify/OSD.

### Словари для проверки орфографии

Нажмите правой кнопкой мыши по полю ввода текста и добавьте словарь с нужным языком. Перезапустите Firefox, снова нажмите правой кнопкой мыши по полю ввода текста и активируйте проверку орфографии.

Или установите через pacman:

    pacman -Ss hunspell

### Добавление поисковых служб

Посетите https://addons.mozilla.org/en-US/firefox/browse/type:4/ и установите нужную поисковую службу.

If you want to custom one, take a look at: `~/.mozilla/firefox/xxx.default/searchplugins/` where xxx is your profile ID).

#### arch-firefox-search

Adds Arch-specific searches (AUR, wiki, forum, etc, as specified by user) to the Firefox search toolbar.

    # pacman -S arch-firefox-search

## Проекты, связанные с Firefox

### Производные

- Iceweasel — Название двух различных форков Firefox. Один из них был проектом GNU; его название сменилось на Icecat. Второй был разработан Debian на основе версии 2.0.

- GNU/IceCat — раньше назывался GNU IceWeasel. Веб-браузер поставляется проектом GNU. IceCat — форк Firefox, использующий исключительно свободные компоненты. Он совместим почти со всеми дополнениями Firefox. GNU/IceCat действительно может полностью его заменить.

### Firefox с лучшей интеграцией с KDE

- firefox-kde-opensuse

  с патчем OpenSUSE лучше интегрируется с KDE. Этот патч считается лучшим многими пользователями.

- kpartsplugin

  This plugin uses KDE's KParts to embed file viewers into non-KDE browsers

- Oxygen KDE

  Этот патч лучше интегрирует Firefox с темой Oxygen, понимая цвета, иконки Faenza и различные настройки.

## Советы и хитрости

## Troubleshooting

### Firefox 4 New Menu Bar/Firefox Button

By default, Arch Linux shows the classic layout of the menu bar. To activate the new Firefox 4 layout with the "Firefox" button replacing the menu bar, uncheck View -> Toolbars -> Menubar.

In GNU/Linux, you will just get a plain grey button instead of the new orange one from Windows. However you can change this to either a Firefox icon or the icon followed by the "Firefox" text.

Adding the following to your `~/.mozilla/firefox/userprofile/chrome/userChrome.css` file will place the icon before the text:

    #appmenu-toolbar-button {
      list-style-image: url("chrome://branding/content/icon16.png");
    }

Adding the following to the same file will remove the "Firefox" text:

    #appmenu-toolbar-button > .toolbarbutton-text,
    #appmenu-toolbar-button > .toolbarbutton-menu-dropmarker {
      display: none !important;
    }

Note: You need to create both the `chrome` directory and `userChrome.css`, if they do not already exist.

### Open containing folder problems (KDE)

If Firefox launches something other than your preferred file manager when using the "Open Containing Folder" option in the Downloads manager, make sure you select your file manager of choice (e.g. Dolphin) in KDE's System Settings:

  System Settings -> Default Applications -> File Manager

If you have already selected your file manager of choice and Cervisia (or a file manager other than your favorite) is opening modify your user's `~/.local/share/applications/defaults.list` to include these two lines:

    x-directory/normal=kde4-dolphin.desktop;kde4-kfmclient_dir.desktop;
    inode/directory=kde4-dolphin.desktop;kde4-kfmclient_dir.desktop;kde4-gwenview.desktop;kde4-filelight.desktop;kde4-cervisia.desktop;

### Firefox keeps creating ~/Desktop even when this is not desired

See this forum post.

### How to prevent plugins from allowing popups?

Ever wondered why pop-ups appear even though you have blocked them? It seems that the Flash plugin can bypass default settings and annoy us with those pesky pop-ups. Fear not, for we can prevent it from doing that.

To get around it:

1. Type about:config into the Firefox location bar.
2. Right-click on the page and select New and then Integer.
3. Name it privacy.popups.disable_from_plugins
4. Set the value to 2.

The possible values are:

- 0: Allow all popups from plugins.
- 1: Allow popups, but limit them to dom.popup_maximum.
- 2: Block popups from plugins.
- 3: Block popups from plugins, even on whitelisted sites.

### Middle-click errors

    ! The URL is not valid and cannot be loaded.

Another symptom is that middle-clicking results in unexpected behavior, like accessing a random web page.

The reason stems from the use of the middle mouse buttons in UNIX-like operating systems. The middle mouse button is used to paste whatever text has been highlighted/added to the clipboard. Then there is the possibly conflicting feature in Firefox, which defaults to loading the URL of the corresponding text when the button is depressed. This can be disabled like so:

Open the browser, and type the following into the address bar:

    about:config

Search for middlemouse.contentLoadURL and set it to false.

Alternatively, having the traditional scroll cursor on middle-click (default behaviour on Windows browsers) can be achieved by searching for general.autoScroll and setting it to true.

### Backspace does not work as the 'Back' button

As per this article, the feature has been removed in order to fix a bug. Follow the next steps to retain the original behaviour.

Open the browser and type the following address:

    about:config

Search for browser.backspace_action and set it to 0 (zero).

### Firefox does not remember login information

It may be cause of a corrupted `cookies.sqlite` file in Firefox's profile folder. In order to fix this, just rename or remove the cookie.sqlite while Firefox is not running.

Open a terminal of choice and type the following:

    $ cd ~/.mozilla/firefox/xxxxxxxx.default/
    $ rm -f cookies.sqlite

Note: xxxxxxxx represents a random string of 8 characters.

Restart Firefox and see if it solved the problem.

### Broken websites / input fields with dark Gtk Themes

When using a dark GTK theme, one might encounter Internet pages with unreadable input and text fields (p.e. Amazon - white text on white background). This can happen because the site only sets either background or text color, and Firefox takes the other one from the theme.

A work around is to explicitly setting standard colours for all web pages in `~/.mozilla/firefox/.../chrome/userContent.css`.

The following sets input fields to standard black text / white background; both can be overridden by the displayed site, so that colors are seen as intended:

    input {
        -moz-appearance: none !important;
        background-color: white;
        color: black;
    }

    textarea {
        -moz-appearance: none !important;
        background-color: white;
        color: black;
    }

This will force the colours ("Allow paged to choose their own colors [..]" setting, in the Preferences > Content > Color dialog):

    input {
        -moz-appearance: none !important;
        background-color: pink !important;
        color: green !important;
    }

    textarea {
        -moz-appearance: none !important;
        background-color: pink !important;
        color: green !important;
    }

Change color values to suit, or use an add-on like Stylish.

### File association problems

For non-GNOME users, Firefox may not associate file types (in the "Open With" part of the download dialog). Installing libgnome amends the problem:

    pacman -S libgnome

If you are using KDE you can also do the following:

    ln -s ~/.local/share/applications/mimeapps.list ~/.local/share/applications/mimeinfo.cache

From now on Firefox should use the applications which are explicitly set in KDE.

### "I'm Feeling Lucky" Mode

"I'm Feeling Lucky" mode lets the user harness the power of Google's "I'm Feeling Lucky" search engine feature via the Firefox address bar.

To activate this mode, do the following (solution from this forum post):

1. Type "about:config" in the address bar.
2. Search for the string keyword.url
3. Modify its value (if any) to

    http://www.google.com/search?btnI=I%27m+Feeling+Lucky&q=

### "I'm Feeling Ducky" Mode (for DuckDuckGo)

"I'm Feeling Ducky" is similar to the Google's "I'm Feeling Lucky" but using the DuckDuckGo search engine.

To activate this mode, do the following (solution using the above one):

1. Type "about:config" in the address bar.
2. Search for the string keyword.url
3. Modify its value (if any) to

    https://duckduckgo.com/?q=!

The last character is a space ' '. It is necessary because if you do not put it, it will become a !Bang.

### "Do you want Firefox to save your tabs for the next time it starts?" dialog does not appear

From the Mozilla Support site:

1. Type "about:config" in the address bar.
2. Set browser.warnOnQuit to true.
3. Set browser.showQuitWarning to true.

### Firefox has high CPU usage and feels slow on scrolling with nVidia GPUs

In some cases, forcing the proprietary nVidia driver to store pixmaps in video memory instead of system memory can yield massive improvements in the perceived performance of pixmap-intensive applications like Firefox. Run

    $ nvidia-settings -a InitialPixmapPlacement=2

from the terminal; if desired results are achieved add this line to a script and use your desktop environment's autorun facilities to execute it on every startup. Alternatively, add the parameter to your `~/.nvidia-settings-rc` and run

    $ nvidia-settings --load-config-only

on startup. This setting is documented in nvidia-settings source code. Make sure you have added other perfomance-improving settings, see NVIDIA.

### Firefox uses ugly fonts on certain webpages

When Firefox uses bitmap fonts, it can happen that on certain webpages the fonts are very ugly (compared to Google Chrome for example):

http://i.imgur.com/SMVdi.png vs http://i.imgur.com/jNmxU.png

To fix that, just disable bitmap fonts for X:

    $ sudo ln -s /etc/fonts/conf.avail/70-no-bitmaps.conf /etc/fonts/conf.d/
