Same problem. very annoying indeed

I can perfectly log-in into this forum but I am unable to log into the opera addons pages.

When I click the login button and enter my credentials:
for a few seconds I get logged in (I can tell because I see the Profile icon change on the upper righ),
the following message appears "Now you will be automatically redirected to the auth service.",
but then I get automatically disconnected.

can anyone help?

I have Opera last version for Windows (26.0.1656.32) and have set it up to synch my bookmarks.
Since I activated the synchronization, my bookmarks don't have the picture any more, the picture that is usefull to identify my bookmarks at a glance.
Do others have this issue or solutions to this issue?

problem solved by choosing another Color theme among the ones available

when I'm in yahoo mail using Opera, the fonts in the main view (the view where I see the list of email of my Inbox) don't look as nice as in IE browser: the caracters are a bit blurry. anyone experienced that? any solution?

thank you both for your feedback

I got the following pop-up window in my opera browser this morning. it says (in french because I'm in France) that I was selected to answer an annual servey on my usage of the Opera Browser and that I will be rewarded a gift of over 50eur for answering it. is it safe?

for me the problem is solved in just updated 18.0.1284.68 version

I use another Gmail theme but have the same layout problem, and also for the folders on the left I usually have a 'more' button to see more folders whereas now I can just not access these hiden folders. also only since last Opera update.
