Opera

Install

Ubuntu

After installing Opera on Ubuntu, a new repository is added (in /etc/apt/sources.list.d/opera.list):

# This file makes sure that Opera Browser is kept up-to-date
# as part of regular system upgrades

deb http://deb.opera.com/opera/ stable non-free #Opera Browser (final releases)

# The line above will make sure you get all final public releases.
# Uncomment the following line if you want to get alpha and beta
# releases, too.

deb http://deb.opera.com/opera-beta/ stable non-free #Opera Browser (beta releases)

But Synaptic complains that an authentication key is missing. To fix it:

# KEYID=9D1A0061   # Old key
#KEYSERVER=pgpkeys.mit.edu       #Alternate server - MIT

KEYID=4E7532C8
KEYSERVER=keyserver.ubuntu.com
gpg --keyserver "$KEYSERVER" --recv "$KEYID"
gpg --export --armor "$KEYID" | sudo apt-key add -

Using DragonFly to debug CSS

DragonFly ({kb|Ctrl-Shift-I}} is a very powerful tool to debug CSS in a webpage. It helps understand how the various CSS properties are computed for any given visual element.

In DragonFly:

• Click on the HTML element you want to inspect
• In the bottom right corner, you can filter by property name to limit to CSS code you want to analyze.

Bugs

Bug report bug-361427@bugs.opera.com

• Type: Other problem / NotSure/Other
• Summary: Keyboard setup changes key shortcut for non-latin keys (AZERTY keyboard)
• How to reproduce:
  1. Get an AZERTY keyboard (eg. Belgian keyboard)
  2. Open the keyboard setup dialog (in preferences -> keyboard shortcuts -> edit any keyboard configuration)
  3. Edit any shortcut, and use '²' as the wanted key shortcut ('³' is the exponent-2 key located at top left of keyboard; on qwerty, it is the back-apostrophe/tilde key).
  4. Close dialog, reopen again, and check shortcut. Shortcut key has been changed to something else.
  5. Back in browsing mode, check that the shortcut '²' doesn't work indeed
• Expected: I expected the keyboard shortcut action to trigger
• Happened: Nothing happens. no actions. It is possible to circumvent the bug by manually editing the .ini file, and copy-pasting the utf8 encoding of the keyboard shortcut key (in my case '²' is encoded as 0xC2 0xB2)
• Platform: Opera 9.50 / Windows
