There is no simple solution for local storage
TL;DR: we have to stop advocating localStorage as a great opportunity for storing data as it performs badly. Sadly enough the alternatives are not nearly as supported or simple to implement. When it comes to web development you will always encounter things that sound too good to be true. Sometimes they are good, and all […]

Storing images and files in IndexedDB
The other day we wrote about how to Save images and files in localStorage, and it was about being pragmatic with what we have available today. There are, however, a number of performance implications with localStorage – something that we will cover on this blog later – and the desired future approach is utilizing IndexedDB. […]

For this, we are defining a set of APIs to access the hardware of mobile devices called the Web APIs. John Hammink of Mozilla published a blog post on the subject on Monday outlining the current state […]

Using client-side storage, today.
I recently tried to store locally the content of a form to make it resilient to inadvertent tab closing and crashes. Here is what I learned about the different ways to achieve client-side storage. Cookies can crumble Cookies are not a valid storage mean, as their size is limited to roughly 4000 characters (4KB) and […]

People of HTML5 – Remy Sharp
HTML5 needs spokespeople to work. There are a lot of people out there who took on this role, and here at Mozilla we thought it is a good idea to introduce some of them to you with a series of interviews and short videos. The format is simple – we send the experts 10 questions […]

Firefox 4: An early walk-through of IndexedDB
Web developers already have localStorage, which is used for client side storage of simple key-value pairs. This alone doesn’t address the needs of many web applications for structured storage and indexed data. Mozilla is working on a structured storage API with indexing support called IndexedDB, and we will have some test builds in the next […]

Beyond HTML5: Database APIs and the Road to IndexedDB
IndexedDB is an evolving web standard for the storage of significant amounts of structured data in the browser and for high performance searches on this data using indexes. Mozilla has submitted substantial technical feedback on the specification, and we plan to implement it in Firefox 4. We spoke to prominent web developers about evolving an […]

Firefox: 46 features you might not know about
Ever since the release of Firefox 3 we’ve been doing a lot of work to add new capabilities for web developers. We thought it would be worth it to make a post that actually listed all of the features that we knew about and people might not know about. This contains everything that we’ve done […]

an HTML5 offline image editor and uploader application
Many web applications use image uploaders: image hosting websites, blog publishing applications, social networks, among many others. Such uploaders have limitations: you can’t upload more than one file at a time and you can’t edit the image before sending it. A plugin is the usual workaround for uploading more than one image, and image modifications […]
