Hey, I have a question, has anyone face this issue of joining a WebEx meeting when you click the link on the invite? Our corporate web email is setup to opening in Firefox ESR(52.5.3 64-bit). And it download a dmg file Cisco_WebEx_Add-On.dmg which is get installed but when going back to the browser (FF) and clicking the link again does the download again and not opening the meeting. And I dont see the WebEx icon in my application as well.
