Hello Mozilla Support Community, I'm an aspiring web developer diving into the world of Firefox add-ons to enhance my workflow. While I'm familiar with some popular add-ons like Firebug and Web Developer Toolbar, I'm eager to explore more tools that can streamline my development process further. I'm particularly interested in add-ons that aid in tasks such as: Code Editing: Are there any add-ons that offer advanced code editing features within Firefox, such as syntax highlighting, autocomplete, or code snippets management? Page Inspection and Debugging: I'm looking for add-ons that provide robust tools for inspecting and debugging web pages. Something akin to Firefox's built-in Developer Tools but with additional features or customization options would be fantastic. Performance Optimization: Are there any add-ons geared towards optimizing website performance, such as identifying and resolving bottlenecks, analyzing page load times, or minimizing resource usage? Cross-Browser Testing: I'm curious about add-ons that facilitate cross-browser testing within Firefox, allowing me to preview and debug my web projects across different browsers without leaving the browser window. Accessibility Testing: Given the importance of accessibility in web development, I'm interested in add-ons that assist in testing and ensuring web accessibility compliance. Version Control Integration: Lastly, I'm wondering if there are any add-ons that seamlessly integrate version control systems like Git or SVN into Firefox, providing convenient access to version control features directly from the browser. If you have any recommendations or personal favorites in these categories or any other add-ons that you find indispensable for web development, I would greatly appreciate your insights. Thank you in advance for your help and expertise!
