Looking for Google Chrome extensions, I've found some additional ones very interesting (equivalent may exist in other Web browsers but it is not the subject of this post).

Comparing some default and additional functionalities of Firefox, Chrome and Opera

Some months ago, I've posted "Firefox add-ons providing more or less same Opera functionalities"; this time, I'll compare Firefox, Google Chrome and Opera functionalities.

Migrate you URL nicknames from Opera to Firefox

Follow those instructions:
 - under Opera, export your bookmarks (e.g. to /tmp/bookmarks.adr file)
 - into a console, parse the file like that :
cat /tmp/bookmarks.adr |tr -d '\n' |sed -e 's/#/\n/g;' |grep "SHORT NAME" |sed -e 's/.*URL=\([^ \t]*\)[ \t].*SHORT[ ]NAME=\([^ \t]*\)[ \t].*$/\2\t\1/g;' > /tmp/urlAlias.txt
 - under Firefox, go to Preferences of Url Alias add-on
 - copy/paste contents of /tmp/urlAlias.txt in "Configuration" panel

Firefox add-ons providing more or less same Opera functionalities

Those are Firefox add-ons which fit more or less some Opera functionalities I found the most useful:

Goodbye Opera, Welcome back my Beloved Firefox Web Browser

I'd used Opera from May of 2008 to March of 2010, against my strong philosophy of open-source software use.

Install 64 bits Java plug-in for Opera 64 bits under GNU/Linux

Since SUN jdk 6 update 10, a new generation plug-in is provided.
This is an article with giving lots of information.
To install it under Opera 64 bit, add the [jdk_installation_dir]/jre/lib/amd64/ under the plug-ins path definition (Tools-> preferences-> advanced-> contents-> plug-ins options-> change path-> add). The corresponding library is libnpjp2.so.

You can check your installation with this site applet.

Get sound working with plugins for Firefox or Opera 9 under Fedora 8 (i386 and x86_64)

In addition to plug-ins installation (see this post), it is needed to ensure having an installed soundwrapper to get sound working under a Web Browser.
Whatever the architecture of the OS, it seems absolutely needed to have a i386 installed soundwrapper.
For instance, install the arts (KDE) soundwrapper:
yum install arts.i386

Install multimedia plugins for Opera 9 under Fedora 8 (i386 and x86_64)

There should be no problem to get multimedia plug-ins installed for Opera 9 under Fedora with a "full" i386 or x86_64 architecture installation.
In some cases, this post may help (Opera being "Mozilla compatible" as Firefox) with installation having i386 and x86_64 components.
Nevertheless, other situations may still need additional instructions to be performed.

It was my case with my installation: Opera 9.27 (i386), under a Fedora 8 x86_64 installation.
In particular, the gecko-mediaplayer package (replacing the mplayerplug-in one) was available only in x86_64 architecture. The nspluginwrapper method does not seem to work with Opera, so a i386 version of gecko-mediaplayer package is needed.
This is quick way to get it installed:
- get a i386 version, for instance browsing the livna repository online, or using yumdownloader under a i386 installation,
- install it using yum (it will install all the needed dependencies)
yum localinstall "gecko-mediaplayer-XXX.rpm"
- the i386 plug-ins might be installed under /usr/lib/mozilla/plugins

To enable plug-ins into Opera, follow the usual way:
- Menu Tools->Preferences->Advanced->Content->Plug-in options->Change path
- add the /usr/lib/mozilla/plugins path (or equivalent)
- valid, and then click "Find new..." button.

Close and launch again Opera.
You may use the -debugplugin option to get debug information about plug-ins.

Finally, under Opera, take a look to the "opera:plugins" information page to check if plug-ins are available.

Install Opera 9 under Fedora 8 (i386 and x86_64)

Those instructions might be interesting for other configuration too (for instance Fedora 7 and prior).
The GNU/Linux Opera 9 package does not seem providing all needed dependencies information. Such a way, even if the rpm is well installed, there might be trouble to launch Opera.

To begin, to install Opera:
- download the rpm of the wished version, Opera 9.27 being currently the latest stable one;
- install it with yum to get the maximum (but not all) needed packages installed too:
yum --nogpgcheck localinstall "opera-XXX.rpm"
- ensure to have qt package installed (i386 for v9.27 and prior; x86_64 might be enough for newer version)
- ensure to have a up to date Java installation to benefit from the maximum functionalities (again, i386 for v9.27 and prior; x86_64 might be enough for newer version)
- it might be needed to update the LD_LIBRARY_PATH to specify where to find some libraries: libqt-mt.so (qt), libjvm.so and libawt.so (Java):
For instance, if you have installed the i386 JDK 6u6 under /usr/share/java/jdk1.6.0_06.i386/
export LD_LIBRARY_PATH=/usr/lib64:/usr/lib/qt-3.3/:/usr/share/java/jdk1.6.0_06.i386/jre/lib/i386/client/:/usr/share/java/jdk1.6.0_06.i386/jre/lib/i386/

Get 32bits firefox plugins available under 64bits system

There is various article about this, but I have not found all needed information into only one.
This is a quick method to get 32bits firefox plugins available under 64bits system:
- install wished 64bits plugins,
- install 32bits plugins if there is no 64bits version (like for macromedia flash),
- install nspluginwrapper 64 and 32 bits (important to have the two versions),
- ensures 32bits plugins are available under /usr/lib/mozilla/plugins (or create symbolic links),
- ensures 64bits plugins are available under /usr/lib64/mozilla/plugins (or create symbolic links),
- according to your OS, it may then be enough to restart firefox (like under Fedora 8),
- else, use the mozilla-plugin-config -i command.

It is possible to not create symbolic link, and to specify path of corresponding .so file with the mozilla-plugin-config -i.

Each wrapped plugins should be under
/usr/lib64/mozilla/plugins-wrapped (or maybe equivalent). If it is not the case, you can use the -v option while using mozilla-plugin-config.

Finally, under Firefox, you should see all available plugins under "about:plugins".
