Change Case Add-on for Firefox: Transform Text Cases

"Change Case" is a handy Firefox add-on that empowers users to easily transform the case of any selected text, whether you want to change it to uppercase, lowercase, or toggle case. This feature is made available through your context menu, making it a hassle-free experience. In addition, as of version 3.10, it even has the capability to correct multiple spaces, ensuring clean and legible text presentation.

Add-on summary

Let you UPPERCASE, lowercase or tOGGLE any selection of text in an input or textarea field by choosing a Change Case item in your context menu. Since 3.10 it can also correct multiple spaces.

Permissions: The Access your data for all websites permission is needed, otherwise it won't work on things like Disqus. But this extension does not access data on pages by default.

The extension only accesses the content of a page (to change case) in an active tab after you activate the extension with the context menu, so I do think that the activeTab permission should be the right permission.

Use "activeTab" rather than "tabs" and host permissions.
