I don't know what XUL is. As I see this on mozilla, this looks deprecated. Is this still used in free communiity? The random instance things is not possible with webextensions. Changing manifest.json entry dynamically is prevented.

Who's Luke? You can find my email id and keys at https://designman.org/ourteam under my name

XUL is the framework that was used for building older Mozilla extensions, before WebExtensions were used.

WebExtensions has a different API than XUL. I recently tried to install on Iceweasel-UXP a very simple extension I wrote using WebExtensions. The extension just blocks small amounts of text. It would not install. basic things, such as the way WebExtensions handles cookies, are different. So you probably won't be able to get a WebExtensions-based extension installed on older versions of Mozilla-based browsers.

XUL is still used, but there probably aren't many people who still use the software (mainly browsers, I think) that XUL-based extensions work for.

I never made a mozilla extension before, xul or webextension,  so I cannot answer at this time, but I am going to go on utox and see if I can chat with him, I will let you know if I find out more info.

PS, if you use the tox network, you could chat with Luke directly. I don't think it would be a problem if I gave you Luke's tox id.  IF wrong I will let you know.

You have my mail and keys. Send me the id. I use qtox.

Send me a normal email. Hyperbola forum email doesn't work. I haven't got anything.

Unfortunately, we do not support WebExt. We have several reasons for this mentioned on the wiki.

So, as zapper mentioned you'll want to make it XUL compatible. One way to do this would be to create a userscript. GreaseMonkey works in all UXP browsers as well as current Firefox. You can even convert a GreaseMonkey script to an XUL binary with this online tool: https://arantius.com/misc/greasemonkey/script-compiler

I think that would be the easiest solution in this case and saves time of creating the XUL overlay, etc.
I would be happy to test your addon and add it to our wiki if you decide to support UXP. You could also submit it to the PaleMoon Addons, but their repository is not "free software" exclusive.

So far most of the work I've done with XUL has been porting existing addons (updating deprecated functions in JS, changing GUID in install.rdf, rebranding, etc.).

However for starting from scratch these are two good tutorials:

https://davidwalsh.name/firefox-extension-template
https://robertnyman.com/2009/01/24/how- … extension/

In install.rdf just put in our GUID's to support our applications. You can use the small NoScript-libre.patch for reference. (Bottom part includes addition of Iceape-UXP's GUID, whereas Iceweasel's GUID is the same as FF52's).

Installing Iceweasel-UXP will not affect Parabola's Iceweasel (since they use different directory structure). Although I've not tested it recently, most of our existing PKGBUILD should be adaptable. For reference: https://git.hyperbola.info:50100/packag … weasel-uxp

However, you can also compile it directly from git, which creates a sandboxed tmp directory isolated from the rest of the system. I tend to use this method regularly myself.

It's fairly simple:

pacman -S [all the dependencies, use PKGBUILD as reference]

git clone https://github.com/MoonchildProductions/UXP
cd UXP && mkdir applications
cd applications
git clone https://git.hyperbola.info:50100/software/iceweasel-uxp.git
cd ..
copy over .mozconfig / apply patches as needed ( git am *.patch )
./mach build
./mach run
