Zotero button missing in safari

nsa12 · October 10, 2024

I've seen this elsewhere, and have tried deleting and re-installing Zotero, but the button in safari still doesn't appear or flashes for a fraction of a second.
M1 iMac, Sequoia 15.0.1
Zotero 7.07
Thanks

If you go into Safari Options -> Extensions is the Zotero Connector enabled?

nsa12 · October 10, 2024

Yes, it is (on Sequoia it's Safari -> Settings -> Extensions)

Do you have other extensions installed into Safari? Have you tried disabling them?

nsa12 · October 10, 2024

Yes, (ad blockers) and I have tried disabling them - it makes no difference. It "flashes" on when I first enable it, then disappears almost immediately, but then flashes on very occasionally.

Could you follow these steps:
1. Disable Zotero Connector in Safari
2. Open Console.app
3. Press "Start" to start logging
4. Enable Zotero Connector in Safari
5. Press "Stop" in Console
6. Type "ZoteroSafariExtension" into the search field in Console and press Enter.
7. Select all items and hit Cmd-C (or Edit -> Copy).
8. Paste them into a text file and send it to support@zotero.org with a link to this thread.

Done, thanks.

Do you run any security software that could interfere with the Zotero Connector? Have you tried restarting your Mac?

nsa12 · October 15, 2024

Yes, Trellix antivirus (my university demands this), and yes, several times...

adomasven · October 15, 2024

You should test with the antivirus disabled. You should talk to your IT if you cannot do this without their permission.

nsa12 · October 16, 2024

tested, makes no difference

Can you create a new temporary user account on this Mac and see if the issue is present there?

nsa12 · October 16, 2024

same behaviour. but weirdly now on the main user the button is there, but the icon itself is wrong - looks like a page with a turned over corner, not a z

That's how the extension works — it shows you what was detected on the page.

that's a new one on me - last time it did work it was just a Z icon... but at least it seems to be working now!

adomasven · October 16, 2024

If it works in a new account it means that some configuration option on your main account is preventing it from working. If you figure out what that is let us know and we will look into fixing it.

Has someone figured out what is causing this problem and how to fix it? I'm having the exact same problem (Zotero extension enabled on Safari, seems to be there for less than a second, then it disappears). I have tried all the suggestion above but it still doesn't appear. This issue has just happened because a couple days ago I was still using the Zotero function on Safari. I am able to use it on Chrome but I prefer Safari overall. For context: I am using a iMac version 11.7.10 (unable to make more software updates).
