How can you detect if a browser supports NPAPI from JavaScript? Not all of them do, and whilst I could rely on the user-agent I'd much rather do it a more reliable way if one exists. Unfortunately, I can't simply detect if my plug-in has loaded or not, as it may be that the plugin simply isn't installed yet on a supported browser. Thanks. There is no JS API for this, but basically all desktop browsers except IE-/Trident-based ones and ChromeOS support NPAPI. You can find out wether your plugin is installed by checking navigator.plugins . If you want to check whether java plugins are enabled or

I want to write scripts for firefox. It seems that firefox has different terms, like add-on, extensions, plugins. and I have a feeling they're not all the same.

I am having troubles loading all the scripts that I am inserting into the page context with <script> tags from a content_script script, because they are required to be executed in the correct loading order, as some depend on others.

Below is the network output with the error caused because of x-tag-core.min

I am writing a webapp that has a browser plugin component for both firefox and chrome. My current testing system uses a series of Selenium tests created through Selenium IDE. Is it possible to also have selenium install, activate, and delete browser plugins for firefox and chrome (possibly other browsers as well)? I think the biggest concern is that installing/enabling the browser plugin requires a browser restart, and I'm not sure if that would through selenium off. The acquisition of the plugin is easily handled by visiting an internal site-link to a php-script that detects your browser. The

I am developing an firefox extension using webExtensions that would help me ease my work with the scenario below. I have to click around 50-60 buttons on the site that update the task status. On click of this button, the web page is calling the webpage's updTask(id) JavaScript function that is then making a web-service call to update the task. I am not able to do this from my content script using the code below: manifest.json : "permissions": [ "activeTab", "cross-domain-content": ["http://workdomain.com/","http://workdomain.org/","http://www.workdomain.com/","http://www.workdomain.org/"] ]
