With Firefox 43 we\u2019ve enabled add-on signing, which requires add-ons installed in Firefox to be signed. If you are running the Nightly or Dev Edition of Firefox, you can disable this globally by accessing about:config and changing the xpinstall.signatures.required<\/a> value to false. In Firefox 43 and 44 you can do this on the Release and Beta versions, respectively.<\/p>\n

In the future, however, disabling signing enforcement won\u2019t be an option for the Beta and Release versions as Firefox will remove this option. We\u2019ve released a signing API<\/a> and the jpm sign<\/a> command which will allow developers to get a signed add-on to test on stable releases of Firefox, but there is another solution in Firefox 45 aimed at add-on developers, which gives you the ability to run an unsigned, restartless add-on temporarily.<\/p>\n

To enable this, visit a new page in Firefox, about:debugging:<\/p>\n

\"Screen<\/a><\/p>\n

In my case I\u2019ve got a new version of an add-on I\u2019m developing; a new WebExtension called \u201cSort Tabs by URL\u201d. To load this unsigned version temporarily, click on the \u201cLoad Temporary Add-on\u201d and select the .xpi file for the add-on. This will load an unsigned add-on temporarily, for the duration of the current browser session. You can see this in about:debugging and also by the green button in the toolbar that the add-on creates:<\/p>\n

\"Screen<\/a><\/p>\n

The add-on is only loaded temporarily; once you restart your browser, the add-on will no longer be loaded, and you\u2019ll have to re-load it from the add-ons manager.<\/p>\n

If you don\u2019t want to go to the effort of making an .xpi of your add-on while developing – you can just select a file from within the add-on, and it will be loaded temporarily without having to make a zip file. <\/p>\n

One last note, if you have an add-on installed and then install the an add-on temporarily with the same id then the older add-on is disabled and the new temporary add-on is used. <\/p>\n","protected":false},"excerpt":{"rendered":"
