I have the same problem. Also using Firefox.

I'm glad I'm not the only one. I think I it started yesterday for me, maybe Monday. Firefox here.

I wrote to support to report the issue. Let's see if they can fix it.

I was gonna ask if anyone had, normally a blue would have seen this topic by now and said something.

Had the same issue today when I tried to log in, using IE Explorer 11... :/

Did happen to me today (first time). Using Firefox 27.0. ;)

Weird, the opposite has happened to me. When I logged in today, it just worked normally again, without any additional logins necessary.

Maybe we got a democratic website engine, which wants to spread the love to each and every user at least once. :p

I sent in a support ticket this morning on this issue and Team GoG responded promptly, though now when I tried to log in again the problem seems to be gone... perhaps they have discovered the source of the problem already.

Not sure if they fixed something (because they still had a question about the the problem), but I can login normally again.

I re-installed Firefox and did the trick for me or unless gog fixed it.

Hmm, trying to log in to the forums today I faced the same issue people had about a week ago. Starting to think it had something to do with the web code for that Irish Luck Promo.

Can't guess what the issue is, but I'm having the same problem again today too... :/

aye, still having this issue myself.

I have the same login problem. I usually have to login twice, sometimes three times. I tested if I mistyped but after typing it into a file and copy it into the login form after the first login nothing happened. After the second try the login succeeded with the same info.

I use the newest Firefox version and it happens on three machines I used to test it (FF on my Desktop, my notebook and Iceweasel at work).
edit: typo -_-
