Mozilla Firefox was the first browser to introduce a private browsing feature which allows you to use the internet more anonymously and securely. History, searches, passwords, downloads, cookies and cached content are all removed on shutdown. Here is how to use this add-on to download a video on Firefox. When you play a video on YouTube.com, you’ll see the “Download” button with red icon, click that button and you’ll get list of all available formats to choose from and save to your hard drive. Click here to install the addon on Firefox. Thanks for reading! May 04, 2019 We’ve released Firefox 66.0.5 for Desktop and Android, and Firefox ESR 60.6.3, which include the permanent fix for re-enabling add-ons that were disabled starting on May 3rd. The initial, temporary fix that was deployed May 4th through the Studies system is replaced by these updates, and we recommend updating as soon as possible. DownThemAll is fast, reliable and easy-to-use! It lets you download all the links or images contained in a webpage and much more: you can refine your downloads by fully customizable criteria to get only what you really want! Be in full control over your downloads, dedicated speed and number of parallel connections at any time.
This feature is available on Firefox for desktop or laptop computers.
Known add-on issues, May 2019: If add-ons are disabled or fail to install, please see Add-ons disabled or fail to install on Firefox.
If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.
Important: Since Firefox will revert to its original state, your own configurations and customizations, including extensions, extension data, and about:config preference configurations are removed. If you've made accessibility configurations, you may need to change them back after refreshing.
Click this Refresh Firefox button directly, if you are viewing this page in Firefox. This won't work if you are using a different browser or on a mobile device.
You can also find a Refresh Firefox button at the top of the Firefox about:supportTroubleshooting Information page.
To continue, click in the confirmation window that opens.
Firefox will close to refresh itself. When finished, a window will list your imported information. Click and Firefox will open.
Note: There's also a Refresh Firefox button in the Firefox Safe Mode window, if you can't start Firefox normally. You can also do a manual refresh by creating a new profile and transferring your important data to the new profile.
All of your Firefox settings and personal information are stored in a profile folder. The refresh feature works by creating a new profile folder for you while saving your important data.
Add-ons which are normally stored inside the Firefox profile folder, such as extensions and themes, will be removed. Add-ons stored in other locations will not be removed but any modified preferences will be reset.
Firefox will save these items:
Bookmarks
Browsing and download history
Passwords
Open windows and tabs
Cookies
Web form auto-fill information
Personal dictionary
These items and settings will be removed:
Website permissions
Modified preferences
DOM storage
Security certificate and device settings
User styles (chrome subfolder containing userChrome and/or userContentCSS files, if previously created.)
Note: Your old Firefox profile will be placed on your desktop in a folder named 'Old Firefox Data'. If the refresh didn't fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don't need this folder any longer, you should delete it as it contains sensitive information.
This article, like all Firefox support, is brought to you mostly by volunteers, who keep Mozilla proudly independent and open source. Keep browsing freely!

Maybe you want to install an add-on on a device without direct Internet connection, a development machine for example.
Security conscious users may want to download extensions too as it provides them with options to go through the source code before they install the add-on in the web browser.
And then there are situations where add-ons are not compatible with the version of the browser that you are using. It is often possible to modify the source of the extension to make it compatible.
When you visit the official Mozilla Add-ons repository you won't find direct download links listed on it.
That does not mean that there is none, only that it is not displayed directly on the page.
Download Firefox add-ons manually
Here is what you need to do to download Firefox add-ons manually. Online pdf deskew.
This works on pages that list multiple extensions and on individual pages of add-ons on the Mozilla website. It is also interesting to note that this works for other programs such as SeaMonkey as well.
Locate the Add to Firefox button on the page you are on. You may need to move the mouse cursor over the add-on to display it on list pages while it is displayed by default on profile pages.
Instead of left-clicking on it to add it to the browser, right-click on it and select Save Link As.
This opens a prompt that you can use to download the add-on xpi file to your local system.
The context menu after a right-click on the Add to Firefox button
The download dialog for the add-on
Note: This works in all modern web browsers. When you use a different browser, a download button may be displayed directly instead which you can click on to initiate the download.
Mozilla displays a prompt then underneath the download button. Here you need to click on download anyway to download the extension to the system.
Installing Firefox add-ons manually
Now that you have downloaded the extension, you can install it directly in compatible versions of Firefox. It is alternatively possible to extract the xpi file to the system first. You can use a program such as 7-Zip for that.
Once done, you can edit the source code as you see fit or audit it.
To install the extension in Firefox, simply drag and drop the downloaded file on a Firefox window. The installation dialog opens up and you can install the add-on as usual.
If you do not like drag and drop, you can open about:addons alternatively, click on the 'Tools for all addons' button at the top next to the search form, and select the 'Install add-on from file' option that is displayed here.
