Just been announced on the list of Xfce la Midori version 0.4.4 one of the lightest browsers available for GNU / Linux.
I leave you my modest translation of the message in English:
We have once again made improvements to GTK + support, which is why the release of this version was delayed. Unfortunately, there are several behavioral issues that could not be traced back to code that indicate that Midori must be compiled with the -enable-gtk3 option to allow support for GTK 3.
The work around the clipboard error was removed WebKitGTK + 1.4.3. It is recommended, however, if it is possible to update WebKit as it also affects applications such as Empathy and Devhelp.
Support for the Unity menu bar has been improved, including work around the hard-coded menuproxy blacklist.
DuckDuckGo has been the default search engine for a while. Meanwhile, it received several improvements. Midori now cooperates with the search engine so that part of the revenue from the ads is donated to Midori through the use of a constant, not a single tag.
The experimental full-screen API used by HTML5 video websites is now supported. Deleting and exporting bookmarks has been improved. IPv6 addresses are best handled when typed in the url bar. The 'Open in Image Viewer' function was implemented.
When starting the private browsing mode an information page is shown aligning the key facts in a different way to the normality of the web browsing sessions. Midori should be safe by default.
As last-minute surprises, if Midori runs with less than 352MB of RAM, the page cache is automatically disabled, which greatly improves memory usage in configurations of this type.
The experimental data policy site finally allows basic whitelisting and blacklisting of Web cookies, local databases and the preservation of compensation values, with private data. Note however that at this time it is not complete, and there is no UI yet.
