I can not install Zotero 5.0 beta plugin via link https://www.zotero.org/download/dev/zotero-5.0-beta.xpi for latest versions of Firefox 48: "Firefox prevented this site from asking you to install software on your computer". Going to Security preferences and making exception to allow installing add-ons from https://www.zotero.org – did not help. If I download XPI file manually, go into "about:addons" Extension tab and select "Install Add-on From File" – it allows to install plugin.
Thanks, now clicking link in this forum display same message, but _fortunately_ also ask if I would like to allow installation.
Remaining strange problem: if I manually copy URL of XPI, paste into address field, press Enter, I still get same message with no option to decide... Again, going to Security preferences and making exception to allow installing add-ons from https://www.zotero.org – did not help even after Firefox 48 restart. Maybe someone has more ideas: maybe this is related to XPI file, maybe regression/bug in Firefox?
It's added security measures. You should always receive that message when a 3rd party site like zotero.org asks you to install a browser add-on, so that's good (and has been the case for a long time).
Pasting the URL into the URL bar is the same, functionally, as installing in a new tab, so same problem there. So everything working as it should (and since this isn't how people would install the actual release, it's also not something you need to worry about).
Again, still problem with installing via link in forum: after allowing installation, it downloads add-on; Firefox ask if I would like to install add-on; if I press "Install", it explains that it will be installed after restart. But after Firefox restart, Zotero add-on don't appear...
In VirtualBox I tested two other systems – I have succes there.
Now again about the complicated system (that I tested for earler comments). I started firefox in Linux console. After Firefox restart for installing Zotero add-on, I see some errors (see http://pastebin.com/raw/HCYMHCuB); but after testing to install other Firefox plugins via about:addons , I noticed, that some other plugins also produced similar result/output, though some other sucessed to install... [added:] Perhaps is related with Firefox bug then using SQL as NSS database: https://bug623317.bugzilla.mozilla.org/show_bug.cgi?id=1236865https://bugzilla.mozilla.org/show_bug.cgi?id=1277295
