Hello, Norberto Andres Furlansorry for the delay, last week when you tagged me I was in PTO.

Please note that I discussed with Diana the reporter of the issues, she will update the steps in few minutes.

We were not able to reproduce this issue on v121 (36341) - with different devices. The bug might still be there but it is very hard to reproduce as you can see:

• A webpage was opened
• Tap on tabs tray
• Tap on the + to open a new tab
• Write fast a new website name and access it

In this time when the loading is happening there is a small transition where the homepage is displayed (including the CFR) and then the CFR remains on the newly opened webpage.

I would say it’s worth to keep it open for now and in case we will reproduce it again or find better steps we add more info to the bug.
