Opera

From Gentoo Linux Wiki

[edit] About

Opera is a web browser and Internet suite. It handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds. It is not free software. Features of Opera include high performance, tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing protection, strong encryption when browsing secure web sites, and the ability to easily delete private data such as cookies and browsing history by simply clicking a button.

[edit] Installation

To install Opera, run: emerge -av opera

[edit] Fonts

To make opera using better looking fonts you can optionally disable xft and core fonts: sudo nano /opt/opera/share/opera/ini/font.ini and uncomment lines: engine:xft=blacklist and engine:x11=blacklist. Consider, however, that CJK languages will no longer display in Opera (my experience, at least).

[edit] Auto-detect proxy settings

Certain computer networks (workplace, university, etc.) require that "Automatically Detect Setting" as in Internet Explorer or "Auto-Detect Proxy Setting for this network" as in Mozilla Firefox be used in order to connect to the Internet. Opera doesn't provide such an option (not 9.23, at least). Although Opera allows one to use an auto-configuration script, it is not able to automatically determine the address of the proxy script. One work around this problem is to determine the proxy settings that Mozilla Firefox uses and set these settings in Opera. To do this, you have to:

• make sure you have a working Internet connection with Firefox,
• browse for a web page (just to make sure),
• determine the proxy by accessing this web page (listed next to the HTTP_VIA variable),
• fill the URL in Opera's Preferences > Advanced > Network > Proxy servers, for the protocols you need (probably HTTP, HTTPS and FTP).

Now Opera should be back on-line. See also Http proxy and the original forum thread.

[edit] Plugins

[edit] Adobe Flash

[edit] gecko-mediaplayer

Consider using gecko-mediaplayer instead of Mplayer Plug-In, by the same author and also based on MPlayer. "Gecko Media Player is a browser plugin that uses GNOME MPlayer to play media in a browser. It should work with all browsers on Unix-ish systems(Linux, BSD, Solaris) and use the NS4 API (Mozilla, Firefox, Opera, etc.)."

emerge -tva gnome-mplayer gecko-mediaplayer

Here seems to work quite fine with Opera.

[edit] MPlayer Plug-In

As of opera-9.50_beta and mplayerplug-in-3.45 no special steps are needed to compile mplayerplug-in for use with Opera. However, Opera may still leave zombie instances of mplayer in memory after the video ends.

[edit] Searchbar

I found a good explanation You can replace search lines in the Opera browser
