Yesterday at Mobile World Congress in Barcelona, Mozilla announced that 18 mobile operators from around the world will support Firefox OS, its new mobile operating system that takes advantage of the power of the web. When those devices begin to ship, Twitter for Firefox OS will be available in the Firefox Marketplace.

Similar to our other mobile apps, Twitter for Firefox OS has a rich interface, featuring the Home, Connect, Discover and Me tabs, as well as the search and compose Tweet icons, so you can easily find and send Tweets from anywhere in the app.

We've also implemented support for a feature unique to Firefox OS: Web Activities. This lets you tweet photos directly out of any app that also supports web activities such as the built-in photos app.

We're excited about the future of Firefox OS, and look forward to phones shipping with support for our new Twitter app.

Tonight was Hollywood’s biggest night for celebrating film, and Twitter hosted a global Oscars party. Whether you were cheering on your favorite nominees or just checking out behind the scenes pictures, Twitter united the audience at home with attendees at the show, bringing them closer to the glitz and glam.

All in all, there were 8.9 million Tweets about the 85th Academy Awards: 2.1 million during the red carpet, and 6.8 million during the awards show. People at home (and in the audience) tweeted as the night’s most exciting and entertaining moments unfolded. The events that drove the most conversation on Twitter this evening, based on tweets per minute, were:

Best Picture award for Argo: 85,300 TPM
Adele performs “Skyfall”: 82,300 TPM
Best Actress in a Leading Role for Jennifer Lawrence: 71,600 TPM
Best Original Song for Adele: 64,000 TPM
Best Actress in a Supporting Role for Anne Hathaway: 60,400 TPM

For many, the Oscars aren’t just about film; they’re about fashion. And people on Twitter are quick to share their picks for best (and worst) dressed of the evening. Celebrities at the show and at home tweeted their favorite looks of the night.

Is white/nude the new black? #oscars.

Just like the movies that the awards celebrate, the Oscars show always delivers a mix of drama and comedy, suspense and surprises, and tears and cheers. As the audience in the Dolby Theatre claps, laughs, and cries, so do the viewers at home. Watching along with Twitter, you can have the best of both worlds: get insider access from stars who know the Oscars best, and join fellow film fans in a global viewing party.

From the red carpet to the Dolby Theatre to their own couches at home, this year’s live-tweeting cast includes:

Attendees: 
Helen Hunt, @HelenHunt (Nominee, Actress in a Supporting Role)
Kristen Chenoweth, @KChenoweth (Oscars pre-show co-host; performing at the Oscars)
Nina Garcia, @NinaGarcia (Marie Claire creative director, "Project Runway" judge)
Louise Roe, @louiseroe (Host, "Fashion Star" / NBC)
Krista Smith, @KristaSmith (Vanity Fair west coast editor)

Couch commentators: 
Katie Couric, @katiecouric (Talk show host, “The Katie Show”)
Carl Reiner, @carlreiner (Actor, writer, producer, author... legend)
Dick Van Dyke, @iammrvandy (Actor, writer, producer, director, acapella aficionado... legend)
Evangeline Lily, @evangelinelily (Actress)
Katie Q Lowes, @KatieQLowes (Actress, “Scandal” / ABC)
Arlene Silver, @speakyteeth (Make-up artist, Mrs. Dick Van Dyke)
Mary Alice Haney, @maryalicehaney (Fashion stylist + editor, Host of “Closet Confidential” / Style)
Matt Roller, @rolldiggity (Writer, comedian)
Erik Griffin, @erikgriffin (Actor, “Workaholics” / Comedy Central)
Heidi Klum, @heidiklum (Model, "Project Runway" host, designer)

For truly insider access, you’ll also want to keep an eye on a few other accounts. Host Seth MacFarlane (@SethMacFarlane) and Producer Neil Meron (@NeilMeron) are sharing behind-the-scenes peeks at everything that goes into Hollywood’s biggest night. The Academy of Motion Picture Arts & Sciences (of “I’d like to thank The Academy” fame), the organizer of the Oscars, will be sharing awards news, presenter lineups, backstage photos, and all sorts of insider details via @TheAcademy.

To follow all these amazing accounts in one place, visit this page. To keep up with the whole conversation from stars and fans alike, use & follow #Oscars, or check out @ABCNetwork’s Twitter buzz page. With the Oscars just two days away, red carpets are being rolled out, gowns are being fitted, and speeches are being rehearsed.

Awards season is in full swing, and tonight’s big show is all about celebrating the best in Latin music. The 25th annual Premio Lo Nuestro music awards show will air on Univision at 8pm ET/ PT; the red-carpet kickoff, La Noche De Estrellas, starts one hour earlier at 7pm ET/ PT. Tune in to Twitter for both, and you won’t miss a beat.

Social media host @AmeliaVega will be with you on Twitter, reporting live to connect you with your favorite celebrities and backstage moments throughout the show.

Here are the best hashtags for joining the Twitter conversations:

#Moda25
Starting on the red carpet, fans can pick their top celebrity fashion moments and interact with their favorite stars via Tweets. By tweeting a star’s name or Twitter handle with the hashtag #Moda25 you can send your vote. Then tune in to see which look will steal the show.

#PLN25 
As your favorite stars work the red carpet, Tweet your comments and questions with #PLN25. Your Tweet could make it to the big screen to be broadcast to the world during the show.

#JenniAplauso 
On a more somber note, Premio Lo Nuestro will honor the legacy of the late star Jenni Rivera. Using Twitter, fans can join a moment of applause in her memory. Via Thunderclap, you can participate in a moment of virtual applause for La Diva De La Banda and share your Tweets with fans around the world.

Here’s a taste of tonight’s fun:
As rehearsals are underway and the nominees prepare to find out the results, stars and performers are already sharing their excitement for the show:

TV host and actress Chiquinquira Delgado (@Chiqui_delgado) is pumped for tonight’s festivities, sampling which dress she’ll wear on the red carpet.

We send out lots of emails every day to our users letting them know what’s happening on Twitter. But there’s no shortage of bad actors sending emails that appear to come from a Twitter.com address in order to trick you into giving away key details about your Twitter account, or other personal information, commonly called “phishing”.

Earlier this month, we began using a new technology called DMARC that makes it extremely unlikely that most of our users will see any email pretending to be from a Twitter.com address. DMARC is a relatively new security protocol created by a group of organizations to help reduce the potential for email-based abuse.

Without getting too technical, DMARC solves a couple of long-standing operational, deployment, and reporting issues related to email authentication protocols. It builds on established authentication protocols (DKIM and SPF) to give email providers a way to block email from forged domains popping up in inboxes. And that in turn lessens the risk users face of mistakenly giving away personal information. If you’re interested in a more technical explanation, you’ll find it here.

While this protocol is young, it has already gained significant traction in the email community with all four major email providers – AOL, Gmail, Hotmail/Outlook, and Yahoo! Mail – already on board, rejecting forged emails. We hope to see it gain more coverage for our users as even more email providers adopt it, and that it gives you more peace of mind when you get an email from us.

Over the past couple of days, there's been a fair amount of conversation about account security on Twitter. We thought we'd take advantage of this moment to remind you of best practices around passwords – both on Twitter and on the Internet generally.

• Use a strong password. Your password should be at least 10 characters that include upper and lower case characters, numbers, and symbols. You should always use a unique password for each website you use; that way, if one account gets compromised, the rest are safe. 
• Watch out for suspicious links, and always make sure you’re on Twitter.com before you enter your login information. Be cautious when clicking on links in Direct Messages. Whenever you are prompted to enter your Twitter password, just take a quick look at the URL and make sure you're actually on Twitter.com. Phishing websites will often look just like Twitter's login page, but will actually be for destinations other than Twitter. If ever in doubt, just go directly to twitter.com in your browser. 
•  Don't give your username and password out to unknown third parties, especially those promising to get you followers or make you money. When you give your username and password to someone else, they get complete control of your account and can lock you out of your account or take actions that cause your account to be suspended. Be wary of any application that promises to make you money or get you followers. If it sounds too good to be true, it probably is! 
• Make sure your computer and operating system is up to date with the most recent patches, upgrades, and anti-virus software. Keep your browser and operating system updated with the most current versions and patches; patches are often released to address particular security threats. 

We offer more detailed advice in our Help Center.

Each year the President’s State of the Union speech, and the opposition response that follows it, ignites a national conversation about a host of issues. Tonight’s #SOTU address and response drew more than 1.36 million Tweets.

If you watched the speech on TV, you could see how members of Congress and political dignitaries responded to the President’s remarks. On Twitter, the ebb and flow of Tweets per minute illustrates some reactions from the rest of us. The highest spikes in conversation occurred when President Obama discussed the following:

- Middle class opportunities & minimum wage; “ladders of opportunity”: 24,000 TPM
- Gun violence victims and need for legislation; “they deserve a vote”: 23,700 TPM
- Early childhood education; “make sure none of our children start the race of life already behind...Let’s give our kids that chance”: 19,000 TPM

During the GOP response delivered by Florida Senator Marco Rubio (@marcorubio), the peak in Twitter conversation came following his pause for a sip of water.  Sen. Rubio poked a bit of fun at himself with a Tweet of his own:

#GOPResponse #SOTU #gop #tcot twitter.com/marcorubio/sta…
— Marco Rubio (@marcorubio) February 13, 2013

Sen. Rubio’s press secretary also shared a Vine offering a peek at what goes into setting up a live national address:

Speaker's conference room is ready for @marcorubio's #gopresponse... vine.co/v/bvEZqQYB7XU
— Alex Conant (@AlexConant) February 13, 2013

And as the official speech and counterpoint conclude, the Twitter conversation continued:

Just left the #SOTU. What are your thoughts? Do you have questions? Send them to me with #AskArne.
