[beta 5.0] Zotero does not start if the Firefox is running
If the Firefox is running before I start Zotero 5.0 then Zotero freeze during the starting process (I see green line). I think it is due to an uninstalled old (4.0.29.18) Zotero for Firefox plugin. After the close of Firefox, the Zotero continue in the starting process and after that, it works. It should be treated before the Zotero 5.0 will be release. The Debug ID is D1772121670.
We'll see what we can do about this. You can either uninstall Zotero for Firefox or install the new Zotero Connector for Firefox over it if you want to be able to save to Zotero from Firefox.
