Zotero connector in Chrome (v 71.0.3578.98) not appearing

harping

Hi there

My connector icon is not showing. I've tried a few of the solutions mentioned in these forums without success as yet. I'm using Connector version 5.0.52 on Mac OS X High Sierra 10.13.6
The Report ID got was 1422268421
Many thanks for any help you can provide.

As in you don't see the Save to Zotero button at all in your Chrome toolbar?

If not, see No Toolbar Icon.

Thanks for your reply. Unfortunately this doesn't resolve my issue. The connector is installed and switched on but no icon appears allowing me to save to Zotero. It's all very frustrating!

And this is part of what I see in the background page:

there's a whole lot more, too much to paste into a comment.

You'll need to figure out what's preventing the extension from showing up. The Zotero Connector is just a standard Chrome extension that defines its toolbar button in the extension manifest, so there's not even any code involved — if it's not showing up, there's a problem outside of the extension itself. You can try uninstalling it and reinstalling, disabling your other Chrome extensions, reinstalling Chrome, or resetting Chrome settings.

Many thanks - I uninstalled all my extensions, restarted Chrome and then reinstalled them. The connector icon is now back where it should be! Have a lovely day :)
