Mac OS X ver. 10.9.4, Firefox: No sign-in / log-in issue or problems downloading. I pretty much never log off from this computer.
Windows XP 32-bit, Firefox: Issue with sign-in / log-in, but I have no problems downloading anything. I regularly log off GOG and clean my cache on that computer.

Find what version of Firefox you are using

Yeah it said Firefox 35.0

I am not in the habit on both questions, however I did logout and back in before posting to make sure that wasn't the issue.

The last time I had cookies removed from the 'puter was when i had to do a factory reset about a month ago b/c of bsod.

I'm also getting the bugs with Internet Explorer 10 and Opera 12.17, so it would seem a valid conclusion.
Seems to be the latest one.

Yes, is says I'm updated. I'm a tech idiot I don't know what I'm trying to figure out here all I know is Galaxy doesn't work for me and yet I don't suffer this problem and yet I'm seeing Galaxy mentioned by a lot people who are having my problem. Jesus, maybe my OS being so old and broken down has saved me this bug.

Got the same problem, i can't access my games, library looks like it's loading all the time. Don't have problems with log in/sign in buttons. I checked both on firefox and IE, and problem is the same. I didn;t participate in Galaxy alpha (don't even know what it is ;p). I did all steps from the other topic (checking .net, deleting data from gog.com in AppData etc.) and nothing helped.

And that may what saved you from entering the club. What browser and system are you on?

Got this problem too.
Here is some more info.

have a laptop where this problem started to show up.
I think that this happened after I did reset my browser cache.
I did reset my my browser (Mozilla Firefox) because i am unable to check out and complete a purchase in it.
The checkout page is just empty in Firefox (tried on 2 different computers).
Later I checked in other browsers (IE-9 and Opera 12.17) in these i can check out, but in neither I can access my account normally. (I mostly uses Firefox so did not care for updating these 2 browsers.)

Now I have a desktop computer here, where GOG still is in working condition. on Mozilla Firefox.
So decided to try and see if I cold make it work on my laptop again. Using data from my desktop.

So did exit Mozilla on botch computer's.
Then i deleted the files for Mozilla's entire config setup and Cache data from my laptop, and made a backup of it.
Next I did copy everything from my desktop to my laptop.
Now when I started Mozilla everything in my account seems to be working correctly again on my laptop.

So If you reset your browser. The error can likely be reproduced.

Edit I forgot to say that I tried installing GOG's galxy and that did not help
(comes with aliens_versus_predator_classic_2000)

I guess we just have to wait. All who are spared, why are you even bothering posting here? To boast?

I am on version 35.0 of firefox and using window's Vista.

To help? Try and isolate the problem to find what exactly is causing it?

Thank you.

Not counting my OP of course, sorry about that.

i am posting hoping to figure out what the exact cause of the problem is. there should be a reason why some of us are and are not affected. don't start fights PLEASE.

That sure would be nice.
