I'm creating a Firefox add-on that does the following:
Drag+drop a file into Firefox
If the file has a certain extension and if FF is running on a certain OS, parse the file with regex
Extract a url
Go to that page
The JavaScript for all of this is pretty straight-forward except for the drag+drop into FF part. How can that be done?
I would just use the Options->Application to have the file open with a parsing app that can then open the url in FF, but FF doesn't recognize my file and won't allow me to associate an app for the file typs using 'always open with' (the checkbox is disabled).
There is a extension that does the drag&drop stuff (drag&drop upload ). You could look at it. https://addons.mozilla.org/en-US/firefox/addon/2190

The firefox's version is 38.0.
When I try to save the monkeygtd based on tiddlywiki, it reports below.
It's not possible to save changes. Possible reasons include:
- your browser doesn't support saving (Firefox, Internet Explorer, Safari and Opera all work if properly configured)
- the pathname to your TiddlyWiki file contains illegal characters
- the TiddlyWiki HTML file has been moved or renamed
Is there any specific setting on firefox?
I got the solution from there
https://www.mail-archive.com/gtd-tiddlywiki#googlegroups.com/msg01979.html
Paste here:
Open this web-page from Firefox: https://addons.mozilla.org/en-US/firefox/addon/tiddlyfox/?src=search
Install the TiddlyFox extension for Firefox
Re-start Firefox
Firefox - How to enable an HTML file to save itself locally?
I use Firefox to open and edit TiddlyWiki.html files.
https://github.com/Jermolene/TiddlyWiki5
These are HTML with a Javascript app packaged together in one file.
They also have this Firefox extension called TiddlyFox that can enable the TiddlyWiki.html file to save itself locally in the file you just opened. It first asks if you want the this ability to be enabled on that particular file and if you click Yes it works.
I was wondering how this behavior is achieved via the Firefox Extension? (ex source code here: https://github.com/TiddlyWiki/TiddlyFox )
Google Chrome has the filesystem api, i dont know if this is how Tiddly does it but this topic solution shows how to do it in chrome:

I have a simple HTML file which references .gadget so that it can be downloaded:
Download me!
IE, Opera, Safari and Chrome all offer saving file to disk, however Firefox loads binary file in a tab. Why does Firefox hate me and what must I do to force Firefox to offer download dialog?
I don't really want to instruct users to "right-click and choose 'save file as'", or that they have to remove .zip extension after downloading.
Server is Apache/2.2.17, in case that it's relevant. Interesting fact is that Firefox does behave like all other browsers - if I load open .html file from local disk. But once it's on the server, it loads file in a tab.
So, here's the solution.
The problem is that Apache returns Content-Type=text/plain HTTP header by default for all "unknown" file types. Firefox adheres to the standards unlike all other browsers so it displays the content. Here's what they have to say about it. You can inspect header in Firefox with Firebug (or simply use curl if you're on Unix).
The above link also hints the solution; register application/x-windows-gadget MIME type with the server. If you don't have access to the server configuration, put .htaccess file in the same directory as your file (or in any of the directories above your directory) with the following line:
AddType application/x-windows-gadget .gadget
After that, don't forget to clear your browser cache.
Do Chrome or Firefox make your extension's source code open to the host machine? And if yes where are the respective folder on Mac?
Yes, assuming some or all of your extension is written in an interpreted and un-obfuscated language. Plain Javascript is common for extensions in both browsers.
For any firefox extension, if you save the .xpi file instead of installing it, it is just a zip file and you can open it with any archive tool (e.g. 7zip or WinZip).
The same goes for the .crx files Chrome. As an test, I just downloaded and opened the .crx for Google Mail Checker Plus using 7zip, and it looks like this is entirely written in javascript and all the source can be read.
In either case, how much usable source code you can get from this depends on the language(s) that are used in the extension.
Google Chrome installs the extension into ~/Library/Application Support/Google/Chrome/Default/Extensions/<EXTENSION_ID>/ and registers it in its Preferences file (according to this).
As heb says, Firefox installs the extension to ~/Library/Application Support/Firefox/Profiles/PROFILE_ID/extensions/EXTENSION_ID/
For Firefox the path is:
/Users/YOUR_LOGIN/Library/Application Support/Firefox/Profiles/PROFILE_ID/extensions/EXTENSION_ID/

I know it's an old topic but for future research.. it could be interesting..so following the link :
How to find extension code?
This article explains very well where are located extensions code for Firefox, Chrome (working on Chromium too of course) on Ubuntu and Windows!
Best,
How can I get the original .xpi file of an extension so that I can make changes to it?
You can Alt-click the green Add to Firefox button in the extension page to save the .xpi file to disk.
