In January 2025, we'll be releasing a version of Zotero that's built
from Firefox 128 ESR instead of Firefox 115 ESR.
We expect the changes for plugin developers to be fairly minimal, so
we're hoping to push out a beta build based on Firefox 128 on
December 21, 2024.
We've made Firefox 128–based builds available for testing on the
'dev' channel:
https://www.zotero.org/support/dev/zotero_7_for_developers#dev_builds
As usual, this channel will only be active until we push out a beta
with these changes.
We've documented the main changes we're aware of here:
https://www.zotero.org/support/dev/zotero_7_for_developers#firefox_115_firefox_128
As always, you can use Zotero.platformMajorVersion to test whether a
Zotero build is based on Firefox 115 or 128, which will allow you to
update your plugin in advance of the Zotero beta that includes these
changes.
Let us know if you have any questions or if you have any trouble
updating your plugins.
