Firefox Containers are a way for users to isolate their online identities and tasks from one another.  In addition to the privacy benefits of containers, containers allow users to be logged into multiple accounts at once without requiring them to use multiple browsers or constantly sign in and out.<\/p>\n<p>After our initial Nightly implementation, we went through various rounds of user research, design iterations, experiments, and finally a <a href=\"https:\/\/testpilot.firefox.com\/experiments\/containers\/\">Test Pilot launch<\/a> to help determine what our users wanted and how containers could meet those needs. We received positive feedback, numerous <a href=\"https:\/\/github.com\/mozilla\/testpilot-containers\/issues?q=is%3Aopen+is%3Aissue+label%3Aenhancement\">feature requests<\/a>, and bug reports. As the Test Pilot phase comes to an end, we have converted containers into a Firefox Extension called <a href=\"https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/multi-account-containers\/\">Firefox Multi-Account Containers<\/a>, accessible to all Firefox users! The extension comes with the latest UI and containers experience, including a number of features that weren&#8217;t available last year.<\/p>\n<h2>What&#8217;s new?<\/h2>\n<p><b>Underline:<\/b> After numerous complaints and bugs with the previous overline tab experience, container tabs are now underlined with the appropriate container color.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/container-underline.png\" alt=\"Shows underlined container tab instead of previous overline.\" width=\"723\" height=\"76\" class=\"aligncenter size-full wp-image-239\" srcset=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/container-underline.png 723w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/container-underline-300x32.png 300w\" sizes=\"(max-width: 723px) 100vw, 723px\" \/><\/p>\n<p><b>Menu:<\/b> There is a new Container Menu button that is accessible in the toolbar with many container options.

You can \u201cHide\u201d your Work tabs and proceed with your Personal tasks.

They aren\u2019t open in the background, eating up CPU power and bandwidth. However, that also means that if you are halfway through filling out a form, your form data will be lost when you re-show the tab.  We hope to fix this in the future so that your form data isn&#8217;t lost.<\/p>\n<p><b>Sort:<\/b> The Container Menu has a \u201cSort Tabs\u201d option and a \u201cMove tabs to a new window\u201d option.

So if you have \u201cWork\u201d and \u201cPersonal\u201d tabs interleaved within each other, you can easily sort them to help organize your tasks (as seen below). \u201cMove tabs to a new window\u201d will take all the container tabs in your current window and move them to a fresh window.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-230\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/unsorted-tabs.png\" alt=\"Personal and Work tabs in random order, ready to Sort\" width=\"1104\" height=\"487\" srcset=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/unsorted-tabs.png 1104w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/unsorted-tabs-300x132.png 300w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/unsorted-tabs-768x339.png 768w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/unsorted-tabs-1024x452.png 1024w\" sizes=\"(max-width: 1104px) 100vw, 1104px\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-229\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/sorted-tabs.png\" alt=\"Personal and Work Tabs after they are sorted\" width=\"1104\" height=\"83\" srcset=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/sorted-tabs.png 1104w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/sorted-tabs-300x23.png 300w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/sorted-tabs-768x58.png 768w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/sorted-tabs-1024x77.png 1024w\" sizes=\"(max-width: 1104px) 100vw, 1104px\" \/><\/p>\n<h2>I wish Containers could do more!<\/h2>\n<p>During the last year, we received tons of feature requests for containers. We found that many feature requests conflicted with each other. For example, if you are in a Work Container, and open a new tab, should the new tab be in the Default Container or the Work Container? Or, if you click a link in a Banking Container, should the link open in the Default Container or the Banking Container? We realized that different users want to use containers in different ways with numerous different use cases. Instead of creating a complicated, feature rich, and potentially confusing product, we created <a href=\"https:\/\/developer.mozilla.org\/en-US\/Add-ons\/WebExtensions\/API\/contextualIdentities\">Web Extension APIs<\/a>. With these APIs, developers can create new Container addons that work for exactly the use case they have in mind. You can <a href=\"https:\/\/hacks.mozilla.org\/2017\/10\/containers-for-add-on-developers\/\">learn more about these here<\/a>.<\/p>\n<p>There are a number of different container related extensions that have already emerged, including <a href=\"https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/containers-on-the-go\/\">Containers On The Go<\/a>, <a href=\"https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/conex\/\">Conex<\/a>, <a href=\"https:\/\/addons.mozilla.org\/nn-no\/firefox\/addon\/context-plus\/\">Context-plus<\/a>, and <a href=\"https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/cookie-autodelete\/\">Cookie AutoDelete<\/a>.<\/p>\n<h2>Quick Tips for Container Tab Management<\/h2>\n<p>We have received a lot of requests from users seeking easier ways to open tabs or links within a specific container. Many of these already exist, but are unfortunately a bit hard to discover. Here are some quick tips that might help an avid containers user:<\/p>\n<h5>I am in Container X and want an easy way to open another tab in Container X.<\/h5>\n<p>With the plus button (or ctrl+T), you will get a tab in the Default Container. To get a new tab in Container X, hold down the control key and press the Plus Button with your mouse at the same time. This will open another Container X tab right next to your previous Container X tab. (Note that Mac users will need to use the command key instead of control.)<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/control-plus-2-cropped.png\" alt=\"Plus button plus control key inherits the Container type from the existing tab\" width=\"533\" height=\"124\" class=\"aligncenter size-full wp-image-227\" srcset=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/control-plus-2-cropped.png 533w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/control-plus-2-cropped-300x70.png 300w\" sizes=\"(max-width: 533px) 100vw, 533px\" \/><\/p>\n<p>Alternatively, if you have a mouse with a middle click button on it, middle clicking the plus button will give you a new tab in Container X.<\/p>\n<p>You can also hold down the control key and press the Refresh button with your mouse at the same time. This will open another tab in Container X with the same website loaded. So you will have two side by side Container tabs visiting the same site.<\/p>\n<h5>I want to open a container without using my mouse.<\/h5>\n<p>Clicking the control button and the period button (ctrl+.) will open up the Container Menu. You can tab through the different container names until you get the one you want to open. Once you have it selected, press Enter and you will get the container you desire.<\/p>\n<h5>I am in Container X and want to open a link in Container Y.<\/h5>\n<p>Right click the link to expose the Context Menu. Select \u201cOpen Link in New Container Tab\u201d and choose which container you would like to use.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/context-menu-open-link-in.png\" alt=\"Right click to open context menu and select which container you want to open the link in\" width=\"702\" height=\"265\" class=\"aligncenter size-full wp-image-238\" style=\"border: #000000 1px solid;\" srcset=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/context-menu-open-link-in.png 702w, https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/10\/context-menu-open-link-in-300x113.png 300w\" sizes=\"(max-width: 702px) 100vw, 702px\" \/><\/p>\n<h5>I want the plus button to show me a list of options instead of just opening a Default Container.<\/h5>\n<p>Go to the plus button with your mouse, click the button and hold down your mouse key for a second or two. \u201cLong pressing\u201d on the plus button exposes a list of containers you could select for your new tab.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/blog.mozilla.org\/tanvi\/files\/2017\/09\/long-press-plus-cropped.png\" alt=\"Long press on plus button to see list of containers you can choose from\" width=\"199\" height=\"173\" class=\"aligncenter size-full wp-image-225\" \/><\/p>\n<h5>I want example-bank.com to always open in the Banking Container and nowhere else.<\/h5>\n<p>Use the <a href=\"https:\/\/jotter.jonathankingston.co.uk\/blog\/2017\/04\/04\/containers-assignment\/\">assignment feature<\/a> described above. Open a Banking Container tab. Go to example-bank.com. Click the Container Menu and select \u201cAlways open in Banking\u201d. The next time you go to example-bank.com in a container other than Banking, the browser will ask you if you would like to use the Banking Container instead. This helps protect you from making mistakes and visiting the wrong website in the wrong context.<\/p>\n<h5>I created a container for my online Christmas shopping, but Christmas is over and I don&#8217;t need the container anymore.<\/h5>\n<p>You can easily delete a container by clicking the Container Menu, selecting Edit Containers, and then clicking the trash can image next to the container you would like to delete. This will close any tabs that are open in that container, and also delete any saved cookies, cache, localstorage, and indexeddb from that container. Note that it will not delete websites you visited in that container from your history. History is currently global and shared across containers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Containers is now available as a Firefox Extension, accessible to all Firefox users.
