nnect() (if connecting to a background script).nnect() (if connecting to a content script).One side listens for connections using runtime.onConnect.

So an alternative pattern is to establish a longer-lived connection between the two contexts, and use this connection to exchange messages.īoth sides have a runtime.Port object, which they can use to exchange messages. Sending one-off messages can get cumbersome if you are exchanging a lot of messages between a background script and a content script. If a content script needs to use a JavaScript library, then the library itself should be injected as a content script alongside the content script that wants to use it: So, for example, if the page includes jQuery, the content script can't see it. One practical consequence of this behavior is that a content script doesn't have access to any JavaScript libraries loaded by the page. This means that content scripts can rely on DOM properties behaving predictably, without worrying about its variables clashing with variables from the page script. The same is true in reverse page scripts cannot see JavaScript properties added by content scripts. confirm ( 'Are you sure?' ) // calls the original nfirm() foo ) // undefined // sees the original form of redefined properties backgroundColor = 'blue' // can't see properties added by page-script.jsĬonsole. Js // content-script.js // can access and modify the DOM let pageScriptPara = document. Using method (3), you can also load scripts into pages packaged with your extension, but you can't load scripts into privileged browser pages (like ' about:debugging' or ' about:addons'). Using methods (1) and (2), you can only load scripts into pages whose URLs can be represented using a match pattern. This means that variables from one content script can directly be accessed by another content script, regardless of how the content script was loaded. There is only one global scope per frame, per extension.

(For example, in response to the user clicking on a browser action.)

: Using scripting.executeScript() or (in Manifest V2 only) tabs.executeScript(), you can load a content script into a specific tab whenever you want.

(This is similar to method 1, except that you can add and remove content scripts at runtime.)

: Using scripting.registerContentScripts() or (only in Manifest V2 in Firefox) contentScripts, you can ask the browser to load a content script whenever the browser loads a page whose URL matches a given pattern.

At runtime, into pages that match URL patterns.

: Using the content_scripts key in your manifest.json, you can ask the browser to load a content script whenever the browser loads a page whose URL matches a given pattern.

At install time, into pages that match URL patterns.

You can load a content script into a web page in one of three ways:

Differences between API implementations.

It will not work on protected pages like addons.mozilla. The new tab button can only open websites right now, it can't open the browser new tab: Sometimes when using the tab bar on top of the screen, cookies prompts may be pushed down: No worries, there is a menu for that (long press the new tab button, see screenshots) There are also settings: you can set which buttons you want to see, the font size, show the bar on top or on bottom, the tab bar height, the search page used when you press the new tab button. To load more of your tabs, swipe right or left the adress bar or select them in the tab switcher: Due to Firefox restrictions, the addon only sees tabs loaded in memory.

How to use: When you start the app, the tab bar will only see the tab which is loaded. There are currently two, this one and Get RSS Feed URL. There select the addon you'd like to install. Open the Addons menu in Firefox (three dots - Addons - Addons Manager)

Paste the following for user id: 15613358 and for collection name: Android-compatible-addons-by-J Under Addons, select Your own Addon collection Tap the Firefox logo on that page 5 times, the advanced options appear Open Firefox Nightly or Firefox Beta settings, open About Firefox there
