Top Mozilla Firefox Addons for Web Developers

Hi all,
Mozilla has definitely seen better days during its time, I’m of course relating to the recent issues it had with it’s CEO, and how that opened up the transparency of the company. In my eyes, it’s all media stuff, and it doesn’t affect me as much.

I’m here to enjoy this browser, just a few days ago, a new version was released to the public. It was the version 29.0 of the Mozilla Firefox web browser, which brought in a couple of changes and security fixes. You can read the release notes for more information.

In 2006, when I began my web journey, Chrome didn’t exist at the time, and everyone was using Firefox as their primary web browser, with the exception of some using the IE, and Opera. These days, Chrome is dominating the market, while Firefox is trying to stay as open as possible, something that appeals to developers all around the World.

Flagfox is an extension that displays a flag icon indicating the current webserver’s physical location. Knowing where you’re connected to adds an extra layer of awareness to your browsing and can be useful to indicate the native languages and legal jurisdictions that may apply. Additional information can be obtained via a multitude of external lookups and users can add their own custom actions. All actions can be added to the flag icon’s context menu and set to icon click or keyboard shortcuts for quick access.
