I recently wrote How to develop a Firefox extension . It’s an overview of the different ways to create add-ons for Firefox and Firefox for Android. It points to the documentation you need to get started but it doesn’t get into specific technical matters. If there’s any particular development topic y…

[image] tim.cooke: I’m creating a side-bar add-on, so I’m pretty sure I can’t use the WebExtensions API, at least yet (please let me know if I’m wrong). That’s correct. There’s a bug filed for it, but no real progress so far. [image] tim.cooke: I’ve tried some of the techniques such as s…

Thanks for the post. I am looking for a good tutorial on reading input from HTML panel, store and retrieve the input. e.g. user entered list in the script. What are the possible ways to do this?

I joined the tb-mailing list but that seems to have died now and maildev digest has taken it’s place but there seems to be no more help for tb developers. I read just recently that legacy non bootstrapped extensions are not to be supported so I looked around and there is NO help that I can see that…

I would like to develop a Firefox addon to provide a much better password manager than the existing ones. The problem is that the fundamentals of Webextensions are not all provided in one place, concisely. When I try to follow the documentation, I get errors like “TypeError: can’t access dead objec…

The main place for documentation is MDN , but you’ve probably seen that already. You can create new threads for the individual issues you’ve run into, in this forum. The community is generally very helpful.

I can tell you from my own experience that reading a lot of MDN is the best way to learn about web-extension / JavaScript development and to avoid errors. Every time you want to use some API, read the MDN first. It’s well written and updated (I’ve never seen such a perfect documentation). Try to re…

[image] juraj.masiar: Try to read as much as possible, not just Anatomy of an extension . Thank you, it is good advice and this is indeed my primary source of information. But it is not complete. Using code similar to MDN generates various errors, not usually in the part that MDN explains, but…

I have to agree with those who have said that a lot of the documentation for the current system of add-on development is disjointed and incomplete which is in complete contrast to the documentation for basic javascript and html. For the past few years I’ve been trying to teach myself how to create …

Tensmoor, I agree with your assessment of the incomplete documentation, although I am unfamiliar with the Android part. For that problem, you might try installing BlueStacks ( www.bluestacks.com ), a nice standard Android emulator. I have no idea whether Firefox Webextensions works with it, though. Be…

That tutorials about How to develop a Firefox extension is so helpful.
