Firefox - Keep compatibility with non-WebExtension Browser

[typhoon71]

If it's possible and not too much work, I suggest to keep compatibility with non-WebExtension "enabled" Browser.
This includes Firefox 47 which is the last stable since Firefox 48 should be out in August(and support WebExtension), and other forks like Palemoon.
I won't ask for Other Chrome derivates because they should already be working (Iron does work).

I'm sorry, but I don't understand the request.

Here's the situation.
WebToEpub was originally written as a Chrome extension. (Actually, I first considered making it a Firefox XUL extension, but when I saw the work required to do that I changed my mind and went the Chrome extension route, much less work.)

When I saw that FireFox is able to run Chrome extensions via WebExtensions, I offered the Extension for Firefox. There was one issue were the "download the packed epub" worked on Chrome but not Firefox. Gusser93 provided a fix.

So, to re-iterate. There is only one WebToEpub. To make the Firefox version I literally take the WebToEpub.zip file I send to Google, rename it to "WebToEpub.xpi" and send that to Mozilla. It works because it uses the WebExtensions.

mmmm, what you wrote means that the addon should never have worked on Firefox 47, since WebExtensions aren't supported on it... But I'm pretty sure I was able to use it a couple of times...
Just asking, did something change in the code that downloads the images?
(issue #27, the second image I posted is what I'm referring to)

Firefox 47 has some WebExtensions support. It's just not fully implemented.
And I've seen the plug-in do funny things on Firefox 47.
As regards downloading, yes, there were some changes in the released 0.0.0.9, to support user specifying Cover as a URL. Is it still not working on Firefox?

[typhoon71]

Nope, it's not working on my firefox (47.0.1)
It didn't work on Firefox 48b5 too.
Maybe it works in Aurora? I will try tomorrow.

[typhoon71]

Awww, wrong button.
Anyway I made an effort and checked with Firefox 49.0a2, and it works.
It'll be a long wait till a stable... (August for the 48)

[typhoon71]

OK, I did some more testing and found that the plugin seems to have compatibility issues with some firefox addons even on Firefox 49.0a2, but it work with a "pure" profile.
I'll test my addons one by one and report back in a new issue.
I'm closing this one (I didn't know it was born as webextensions addon).
