To be honest, I didn’t use the bookmarklet for a long time. But I’m quite sure it was working before as expected. For now, I’m prompted for credentials on every use of the bookmarklet, and I’m logged out of ownCloud in the other tab. Weird!
As I haven’t touched the bookmarklet for a long time, I assume that is the result of some kind of newer security thing in ownCloud or in the browser.
Meanwhile, I know it was working (more or less) with ownCloud 10.6. But even with 10.6, the login gets lost, you have to login again for each bookmark, even if you are logged in another tab. I’m quite certain this was working before, but it might also be related to a newer Firefox version.
