I am using Ubuntu 17.04 and Chromium browser. I just noticed that in my Google account permission page, I had given full access to Ubuntu. I never did that. So I revoked it. When I did that, I noticed my Chromium browser and all my gmail tabs were signed out. When I signed in again, Ubuntu has gained full access to my account.
Therefore, I installed Google Chrome. when I did that, I resolved this problem.
I installed Chromium browser by typing in
sudo apt-get install chromium-browser
Here is a screenshot to prove my statement.
It is ridiculous if Ubuntu has actually gained full access to my Google account. I did not authorize it and it seems very unethical of Canonical to do it. But may be this some mistake of mine. If so, I apologise for my statement. Either way, I would like to know what is the reason for this to happen with Chromium but not with Google Chrome browser.
Appreciate your valuable time.
