I uninstalled the zotero and reinstall the latest version, and even reinstall the firefox browser, I still can't open the Zotero. Can anyone help me, Thanks very much!
You should uninstall Zotero completely — make sure that C:\Program Files (x86)\Zotero (for Zotero 6) or C:\Program Files\Zotero (for Zotero 7) is gone — and then reinstall it. This is usually caused by an incomplete upgrade and is almost always fixed by a reinstall. If you're still getting it after that, it might be due to malware or security software on your system interfering with Zotero.
