I had to downgrade Opera, the browser after the latest update. This was easy to do. I installed the downgrade script from the package manager and typed “downgrade Opera”. It gave me versions to select from. I wanted to downgrade to the version right before the update:
70.0.3728.154. The latest update installed Opera v. 71.x.x. which caused problems.
The problem was that the back tab arrow was not showing the recent history of my activity. That is fixed now.
