The “Share on Twitter” extension for Mozilla Firefox is a useful and light-weight extension for Twitter users. You can use this extension to share current tab, links and selected text on Twitter.com directly, without any authorization or third-party access.
How To Use
Install the extension from this link. Once installed successfully, you can notice its icon on the browser toolbar, as shown below:

Click this button to share the current tab on Twitter. Alternatively, you can share the current tab using the context menu options or Firefox’s Tools menu option.



Share Links or Selected Text
Right click on any link or selected text snippets, and select the option in the appeared context menu to share that on Twitter.


Change Options
By default, this extension launches sharing link in a popup window. But, if you like, you can opt to open the sharing link in a new tab. To set this option, right click on extension’s toolbar button and select “Manage Extension”.

This should launch extension’s entry on the Add-on Manager. Move to Options tab as shown in the following screenshot, and select your choice from the dropdown menu. You can also refer this article for detailed information.

Hi, just a small, humble suggestion: after a page is shared via this extension, the pop-up window should immediately close when it is done.
Otherwise, thank you for this extension. I needed to share a Reddit thread to Twitter in Mozilla Firefox web browser on my PC but the website, obviously a social media competitor to Twitter, did not have a way to share it directly there. I appreciate it very much.
The option to remove the graphic doesn’t exist when it’s the 64 bit version of Firefox.
This extension is fantastic, it’s just what I needed!
One feature it needs: it’s not aware of Firefox containers, or what container it’s in. If I click or right-click on “Share on Twitter” inside a container, it opens a tweet from the default container. This would make it even better and smoother.
Thanks again 🙂
