Martin,
Can you please let us know how adding the "Download Chrome Extension" to Opera enables installation of the LastPass Chrome extension v.4.3.0?
After installing "Download Chrome Extension" in my Opera, then going to the Chrome web store and selecting LastPass, I see the panel that describes LastPass, but the "button" for initiating installation is absent. Ergo, I cannot install it.
Please let us know how you did it.
I'm running Opera 25.0 under El Capitan using a 2011 iMac.
Mit freundlichem Gruss aus Virginia!
Boris
