Firefox

Debian wiki

Note about preferences: normally, your preferences, bookmarks, extensions, etc should be understood automatically when you start the new Firefox. However, there's always the possibility that something might not work and you could lose them. Do a backup first.

Note about Zotero: Debian's Zotero package depends on the Firefox package. Which means that you can not uninstall Debian's Firefox if you have Zotero installed. A solution to this is not to install Zotero from Debian's repository: see Zotero section in the useful stuff page about how to do it.

Firefox-esr

Firefox-esr is included in the Debian repositories. It tends to be a realtively old version, but has the advantage of updating automatically with a system update.
