Psono fails to decrypt secrets if links are opened in new windows (instead of tabs)
If a user configures Firefox to open new Windows instead of new Tabs (the legacy behaviour for target="_blank"), psono consistently fails to decrypt and open the secret.
While in this state is a single CPU is under 100% load and nothing happens, the new window "loads" without end.
Sometimes (about 1 in 10 cases) you can see a site rapidly being refreshed (the tab title flickers like on pressing reload multiple times in a row).
Both cases can be resolved most of the time by setting focus to the URL bar and hitting ENTER (or SHIFT+ENTER), thus loading the URL manually without cache. (The "reload page" Button does not work in this state, since the page was not yet successfully loaded only the "blank page" or "new tab" page gets reloaded.)
I'm not sure if this is a firefox-specific bug, since chromium does not even have the option to open new windows instead of tabs :-)
