Install by downloading the latest release – if you use Firefox, make sure to right-click and save the XPI file, not just clicking it – and then in Zotero:

  1. In the main menu go to Tools > Add-ons
  2. Select ‘Extensions’
  3. Click on the gear in the top-right corner and choose ‘Install Add-on From File…’
  4. Choose .xpi that you’ve just downloaded, click ‘Install’
  5. If you’re using Zotero 6, restart Zotero. Installation in Zotero 7 requires no restart.

After the initial installation, the plugin will auto-update to newer releases, so you should need to perform the process described here only once.

Note: the default setting of BBT will generate different citekeys than Zotero would itself generate; the keys from Zotero are not always safe for use in bibtex/biber. If you want to get the stock zotero keys, set the pattern in the preferences to zotero. I very much recommend not choosing zotero as your pattern unless you have existing articles that use keys generated by previous Zotero-native BibTeX export.

Note: BBT needs to be installed in Zotero, not Firefox. There used to be two versions of Zotero, one standalone, and one that was installed in Firefox. BBT is a Zotero extension and lives where Zotero lives; Zotero is no longer available as a Firefox plugin, only as standalone. If you download BBT using Firefox by simply (left)clicking on it, Firefox will download it, think it is a Firefox plugin, try to install it, and will fail with a complaint it is corrupt, hence the right-click and save.
