New Features in Opera 54
- News on Speed Dial
Fifty news articles will be shown just below the Speed Dial folders. Clicking on an article will open the story as expected. Furthermore, you are able to read the news in your preferred language. You can filter the content in multiple categories and much more.
- Recovery / Update section
With the present improvements of Opera, recovering has been made easier to access. This is achieved by virtue of the Update and Recovery menu page, which can be accessed by clicking on the O Menu button (for Windows / Linux users) or by clicking Opera in the menu bar (for Mac users).
Then you will see this option:
You can see the current version of your browser under Update. Just click the Check for update button in this menu and Opera will scan for a new version of the browser and if there is, an Update button will appear.
Also you can click the Recover... button to choose a reset option and have your web browser reseted by settings or by data and settings both.
