Now, after lots of lines of code, you are finally able to test them on both OS X and Linux. Thanks to the many optimizations, these new tabs also close faster than before. Find out how to try out the curvy tabs.

Mozilla’s DNA and Mobile World Congress

Because Mozilla would not exist without participation of volunteers in every aspects of Mozilla’s work.

Mozilla Tagalog Localization Marathon in Manila
Philippines has rich linguistic diversity: Today, you can hear smattering of at least five languages in Tagalog, the widely used Philippine dialect. In 2010, Seth Bindernagel kick-started the localization of Mozilla Tagalog. While 42% have already been translated, it looks very promising. This quarter’s translation efforts will be kicked off with a Translation Marathon in April. Learn more about how you can take part in Arky’s blog post.
