Recommended Browser Add-ons

Not all of these add-ons are necessary, and many provide redundant functionality. Choose the ones you need, and learn more with our guide to Firefox Privacy.

Worth Mentioning

floccus - Synchronize bookmarks across browsers via Nextcloud, WebDAV or a local file (and thus any file sync solution). For Firefox, Chrome, Edge.

Additional Functionality

These add-ons don't necessarily add to your privacy when browsing the web, but add additional functionality to your browser you may find useful.

Persistent storage management

Desktop

These add-ons are the preferred method for controlling persistent storage data that various websites and web-apps may create on your computer.

{% include legacy/cardv2.html title="Temporary Containers" image="/assets/img/legacy_svg/3rd-party/temporary_containers.svg" image-dark="/assets/img/legacy_svg/3rd-party/temporary_containers-dark.svg" description="Temporary Containers allow you to open tabs, websites, and links in automatically managed disposable containers.

Android

Unfortunately the Android version of Firefox doesn't yet have Temporary Container support. The recommended extensions below are a substitute, however as APIs do not exist for clearing IndexedDB, Service Workers cache, appCache, or cache by host. As a result they are not as good as the above Temporary Container suggestions.
