Issue with last version of zotero 4.x
I installed Firefox ESR and installed zotero 4.x don't look at the version and every think was fine, but the version show you that message remind you of zotero 5.0 stand alone with the new version of FF, and you can't use local archive because zotero 5.0 which I descard it convert it to its structure. ok no problem I downloaded from server.
but suddenly zotero disappear and zotero connector appear instead, before that FF esr has sudden hang for few seconds from time to time, zotero is the only plugin.
I installed old buckup zotero 4.0 from long time and worked again but has to stop auto update which is very important.
zotero 4.0 from my disk worked good without the sudden hangup of FF, but it missing many features was added to newer versions.

I think it's good if you make the old version without the upgrade warning available for user somewhere, SF.net for example, I already have backup
