Lightning no longer working on 2.37 builds
Per this blog entry and actions taken already in Bug 1159737 - Stop supporting binary XPCOM components except as part of the application, the Lightning extension (and any other add-on using binary components) is no longer working. Since there is no build-time switch, either Lightning has to work around the issue per suggestions made in the blog entry, or the Firefox people have to be convinced to either introduce a build-time switch or some white-listing mechanism for affected but "trustworthy" add-ons.

Re: Lightning no longer working on 2.37 builds
As well as Lightning, I seem to recall Mouse Gestures Redux (and its successors?) using a binary component. Is this still the case?

Re: Lightning no longer working on 2.37 builds
I couldn't find that one, but LemonJuice's Mouse Gestures Suite doesn't have any binary component (I don't know if it's a direct descendant of the add-on you have in mind).

Re: Lightning no longer working on 2.37 builds
Mouse Gestures Suite is a descendant of All-in-One Gestures. Yes, Redox uses binary components so I suppose it will fall into the category of not working any more in future Firefox (and maybe SeaMonkey) versions.

Re: Lightning no longer working on 2.37 builds
Ah well, I guess I'm going to have to finally abandon Mouse Gestures Redox. It's a shame, since I've been using it since the Optimoz days. Oh well, at least there's something to jump to, so thanks to Lemon Juice for that .

Re: Lightning no longer working on 2.37 builds
Download an affected FF version & test.
(Are there such things, now?)
Just because there is a "binary" in the package, does not mean it will not work.
Has Mouse Gestures Redox needed to update, regularly, with each FF release, or has it "just worked" regardless of FF version updates?
FlashGot includes a "binary component", but its "component" has remained unchanged for ages (years), & AFAIK won't be affected by this change. (So suppose what is considered a "binary component" is/could be more then simply having a .exe in the extension package.)

Firefox 40.0a1 should be.

Re: Lightning no longer working on 2.37 builds
Yes, binary components aren't disallowed as such, but their methods of interacting with the main application are substantially restricted. One can use a child process to invoke an executable (".exe" on Windows), but it's also possible to load dynamic/shared libraries (".dll") using JavaScript ctypes. Lightning is probably directly connecting with XPCOM, which is the method now no longer permitted as it's too "direct" in its involvement with the main application.

Re: Lightning no longer working on 2.37 builds
Mouse Gestures Redox appears to use ctypes, unfortunately.
It's a shame the Firefox guys care so little about extension compatibility, especially on other Mozilla based projects. Causing so much trouble for Lightning is not nice. Would it hurt them in any way if they simply disabled XPCOM for Firefox leaving it for use in TB and SM?

In this case it should still work (js-ctypes is actually recommended as the second-best workaround after removal of the XPCOM part).

It wouldn't, but they failed to even consider a build-time switch. Bsmedberg said in one of the threads repeatedly that he would approve such a patch, but wouldn't write it (thus, crash the barn door but refuse to help catching the horses...).

Oh, yes, I misunderstood you initially about ctypes - Redox should be safe then, it works in the latest Fx nightly, it only has problems with e10s so potentially SM users will not be affected.

Re: Lightning no longer working on 2.37 builds
BTW: Fallen has reported in today's SeaMonkey status meeting that Lightning has been switched by default to icaljs (i.e., the JavaScript version of the binary parts), which "works" but has performance issues and likely still a couple of bugs as it hasn't been extensively tested. Thus, if nothing else happens until the Gecko-40 cycle hits the releases, that's probably what SeaMonkey/Lightning users would have to work with as the fallback.

Re: Lightning no longer working on 2.37 builds
Mitigating patch landed on mozilla-central, introducing a build-time switch to allow binary XPCOM components again:
- #1165428 Restore support for binary components in extensions on a per-application basis
- #1166842 Re-enable binary extensions for comm-central
