Opera is not present in the default Ubuntu repositories, however it is available by ppa. Open a terminal and run the following commands:
wget -O – http://deb.opera.com/archive.key | sudo apt-key add -
sudo sh -c ‘echo “deb http://deb.opera.com/opera/ stable non-free” >> /etc/apt/sources.list.d/opera.list’
sudo apt-get update
sudo apt-get install opera
Users of AVG 2012 antivirus software will already have noticed the AVG Advisor pop-ups informing you about high memory usage of browsers (I usually get them from 300 MB RAM upwards) which come up relatively often and are quite annoying since your browser uses more memory the more tabs you open.
But as in most cases you can simply disable this feature along with the memory monitoring. To do this, open the AVG control panel from the tray icon. On the top bar, click on Tools and select Advanced settings…. In there, select Appearance from the left panel. Under System tray notifications, uncheck the Display AVG Advisor notification to turn those off and click Apply. You will now no longer be warned about your browser’s memory usage.
Apart from the usual Bookmarks and Bookmarks Toolbar, the SpeedDial screen introduced a great visual option for quick access to your most commonly used websites. It currently is the main new-window-replacement on the Opera browser and can be downloaded as an add-on for Firefox.
It can be downloaded on the Mozilla Firefox add-on page here: https://addons.mozilla.org/en-US/firefox/addon/speed-dial/
The screen is highly configurable in terms of when to show up, which actions to perform on click and keyboard input, largeness of panels, number of panels etc. You can also put them together to groups which are then displayed as tabs in a seperate group bar.
Like any other browser Opera has many options to let it be configured precisely to your likings. This is done through the usual interface as well as through a configuration page just like Firefox’ about:config.
A great deal of options is already offered in the preferences accessible by going to Opera > Settings > Preferences…. Apart from the usual actions such as form premades, text formating and search engines I’d like to point out a few that might come handy:
In Preferences, go to History on the left pane and set Check images to 24 hours. This lengthens the time span that images are stored in the cache, so they don’t need to be reloaded from the page if you reaccess it.
Afterwards, go to Browsing on the left pane. The option Smooth scrolling gives you a better feel about scrolling, but will most likely cause speed issues with some sites. It’s up to you what you prefer but if you go for performance better disable it.
Close Preferences now. If you need more space for tabs, you may consider right-clicking the tab bar and choosing Customize > Appearance…. Go to the Toolbars tab and set Wrapping to Wrap to multiple lines. This will expand the space you have for tabs vertically.
If you want more options, enter opera:config into the browser’s url bar. This will give you a long list of them which, howeverm want to be handled with care.
If you don’t like Opera’s mouse gestures for example which appear on holding the right mouse button, simply go to User Prefs > Enable Gesture and untick the box.
