Add-ons to make Firefox more fantastic

Useful browser extensions I usually have installed. Note that it is possible to install addons without having them all enabled at all times so you can turn off whatever you are not using at the moment. This is more efficient and secure.


  • Browser enhancement

  • xBrowserSync

    Free Mac Windows Linux Android Android Tablet ... Self-Hosted Chrome Firefox Website

    Free and open source tool for syncing your browser data between browsers and devices whilst maintaining your privacy and anonymity.

  • Floccus

    Free Self-Hosted Microsoft Edge Vivaldi Browser Chrome Nextcloud ... Google Drive Nextcloud Bookmarks Opera Website

    The goal of this project is to build a browser extension that syncs your browser data with Nextcloud. Historically this was once possible using the mozilla sync owncloud app. However, Mozilla tried to improve Firefox Sync and dropped support for the old API.

  • Downloading

  • Simple Mass Downloader

    Free Web Chrome Website

    A simple but powerful bulk/mass downloader. Download links from multiple tabs at once. Advanced filtering & multi-renaming options.
    This is a light and unobtrusive chrome download manager and batch downloader (no annoying sounds or animations; only minimal notifications).

    MAIN FEATURES:

    [A] The links may be extracted from multiple open tabs, clipboard, or from selected text on web pages.

    [B] Advanced filtering / mass renaming capabilities using various name masks.

    [C] For images there is a special thumbnails view where items may be ordered by the size descending order or filtered by width/height.

    [D] User-defined Automatic Folders where downloads can be automatically directed based on custom rules.

    [E] User-defined Favorite Folders, easily accessible when the user writes a custom download directory.

    [F] Flexible download management, the user can:
    a) pause, resume, open downloaded files etc. (usual features)
    b) set server limits

    Unlike an external software that usually only uses the information contained in the link url, this mass downloader can take advantage of the various text attributes of the links on a web page (url, title, text, alt text etc.) and use them in various contexts (when filtering the resource list, multi renaming resources or defining rules for automatic folders etc.). The links may be extracted from multiple open tabs|clipboard|selected text, and the user marks for download some of them. Before downloading, the user may (multi) rename the selected files using various name masks, or even search/replace text inside names (eventually using regular expressions).

    Note that unlike other bulk/mass download managers, this file downloader doesn't load automatically links (only) from active tab. The user adds explicitly links from the active tab|all tabs|left or right tabs, or using the web page's context menu.

  • SingleFile

    Free Mac Windows Linux Chrome Firefox Website

    SingleFile is an extension that helps you to archive a complete page into a single HTML file or HTM-File with Google Chrome and Chromium.

    In version 0.0.76 it is not possible to save only a selection without advertising text at the edges of a site, as you can with unMHT. But the author gildas promised to implement this feature in one of the next versions.

    Saved files are compatible with Firefox, Opera, Safari, Konqueror and partially with Internet Explorer 8, if you uncheck the option "remove unused CSS rules".

  • Video DownloadHelper

    Freemium Mac Windows Linux Chrome Firefox Website

    DownloadHelper is a tool for web content extraction. Its purpose is to capture video, audio, and image files from many sites.

    Just surf the Web as you are used to, when DownloadHelper detects it can do something for you, the icon gets animated and a menu allows you to download files by simply clicking an item

    For instance, if you go to a YouTube page, you'll be able to download the video directly on your file system. It also works with MySpace, Google videos, DailyMotion, Porkolt, iFilm, DreamHost and others. You can even setup the extension to automatically convert the downloaded movies to your preferred video format.

    When you are on a page containing links to images or movies, you can download some or all of them at once. Moving the mouse over the items in the menu will highlights the links directly in the page to make sure they are the ones you want to pick up.

    DownloadHelper also allows you to download files one by one, so that you keep bandwidth to surf for other stuff to download.

    Because of Google WebStore restrictions, the Chrome version of the add-on does not download videos from YouTube. Use the Firefox version for this purpose.

    Easily open disposable containers that isolate attached data and are deleted after usage: Fully automatic, based on navigation-target, for certain websites, with configured mouse clicks on links or just by using the toolbar icon.

    The Automatic Mode will overwrite your standard ways of opening new tabs - even when opened from an external program. Instead of opening tabs in No Container, it will open them in a freshly created Temporary Container. No more cookie, cache and storage collecting in one place, everything happens in its own isolated Temporary Container. If you enable Automatic Mode, you should also configure Mouse Clicks to open new Temporary Containers. Recommended preferences:

    Isolation > Global > Mouse Clicks:
    Middle Mouse: Always

  • Facebook Container

    This extension helps you control more of your web activity from Facebook by isolating your identity into a separate container.

  • Firefox Multi-account Containers

    Free Web Firefox Website

    The Firefox Multi-Account Containers extension lets you carve out a separate box for each of your online lives – no more opening a different browser just to check your work email! Here is a quick video showing you how it works.

    Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. With the Firefox Multi-Account Containers extension, you can...

    Sign in to two different accounts on the same site (for example, you could sign in to work email and home email in two different Container tabs.
    Keep different kinds of browsing far away from each other (for example, you might use one Container tab for managing your Checking Account and a different Container tab for searching for new songs by your favorite band)
    Avoid leaving social-network footprints all over the web (for example, you could use a Container tab for signing in to a social network, and use a different tab for visiting online news sites, keeping your social identity separate from tracking scripts on news sites)

    After installing the Firefox Multi-Account Containers extension, click the Containers icon to edit your Containers. Change their colors, names, and icons. Long-click the new tab button to open a new Container tab.

    Privacy in Firefox Multi-Account Containers

    The Firefox Multi-Account Containers extension does not send any information to Mozilla.

    Haven't I seen this in Firefox before?

    Firefox Multi-Account Containers was first introduced as "Containers" available only in Firefox Nightly. It went on to be a Test Pilot Experiment, where we improved the user experience and added new features. Now it exists here as an extension that can be installed by all Firefox users.

    Although you can still use the feature built into Firefox Nightly, we recommend using this extension as it has a richer user experience.

  • HTTPS Everywhere

    Free Web Vivaldi Browser Chrome Yandex.Browser Opera ... Chromium Firefox Website

    HTTPS Everywhere is a browser extension produced as a collaboration between The Tor Project and the Electronic Frontier Foundation. It encrypts your communications with a number of major websites.

    Many sites on the web offer some limited support for encryption over HTTPS, but make it difficult to use. For instance, they may default to unencrypted HTTP, or fill encrypted pages with links that go back to the unencrypted site.

    The HTTPS Everywhere extension fixes these problems by rewriting all requests to these sites to HTTPS.

    HTTPS Everywhere can protect you only when you're using sites that support HTTPS and for which HTTPS Everywhere includes rules.
