Firefox & Thunderbird Add-on Converter for SeaMonkey

[Ztruker]

Thanks Frank, would be good to have.

Thanks Frank, would be good to have.

Here you go, you want version 49 -
https://addons.mozilla.org/en-GB/firefo ... -explorer/

With the AMO browsing extension that would be - chrome://amobrowsing/content/versions.html?host=addons.mozilla.org&id=690742&beta=false

I notice that I have this flagged as having needed to write css for it. Here that is, it whacks an unneeded entry on the context menu -

Code: Select all

/* Frank whacks dross on context menu...*/
#context-viewbgimage,#openwithinex-openwithinexbackground {
   display: none !important;   
}

The extension works very well.

That works, thank you. I got an error when I installd it but it disappeared before I could capture it. Even so, I have the Open Link in Internet Explore Context Menu entry and it works.

Now I get an error every time I start Seamonkey:

Can't get an image to take here. This is what it says:

TypeError: tabContextMenu is null
284

Edit: I disable the Add-on and the error went away. When I disabled it, I got this error:

TypeError: document.getElementbyld(...) is null
309

Now I get an error every time I start Seamonkey:

Looks like your search goes on. All I can say is that I'm using their version 49 on the same SM version as you're using and I'm not getting that.

I'll uninstall and reinstall and see what happens.

Thanks

Edit: Same problem. Could this be caused by one of the other extensions I have installed?

(I get the same messages, XP, if that matters. Nonetheless the extension looks to work. [As it is have no need for it or IE .] And that popup error on browser startup would be a no-go for me in any case.)

I'm getting ""install.rdf not found in installer" for every single addon I try no matter what. Even extensions that are known to work, I've tested 10 random add-ons from page 1 and 100% of them have this error. I tried an old XPI file of greasemonkey that I know for sure worked a year ago and even tried using seamonkey 2.48 and it still does not work - when I know for absolute certainty this used to work on 2.48. Did this converter get broken? What is going on?

Name of addons plus the version numbers tried, please.

No, the converter did not get broken but the new extensions for Firefox changed since Fx now uses Web Extensions, a completely different format, which does not contain install.rdf file, hence this error. What this means is that no current extensions for Fx will work with the converter and there is no way to convert them to SM. The only hope is that maybe some day in the future SM will support Web Extensions - but this is all very uncertain now. The first page links to Firefox add-ons site, which now does not host any legacy extensions, so none of them will work. Only if you can find a link to an older version of a Fx extension (for version 56 or before) you can use the converter for that.

Unfortunately CanvasBlocker (listed as compatible) cannot be converted:

install.rdf not found in installer

It's a webextension.

[Frank Lion]

Unfortunately CanvasBlocker (listed as compatible)...

Tested Versions: 0.1.6-Release

When it was tested it was compatible, but they've since dropped those versions. It happens.

(This is an archive of "legacy" extensions. I can't vouch for it, but presumably it's OK?)
Try here, CanvasBlocker, http://legacycollector.org/firefox-addo ... index.html.

[Anonymosity]

It is a shame that Justoff's extension for Pale Moon, Classic Add-ons Archive, will not work with SeaMonkey (at least, I doubt that it does). That archive has quite a number of legacy Firefox extensions.

ca-archive-1.2.2.xpi is supposed to work with SeaMonkey according to Rainers German page: https://seamonkeyde.wordpress.com/
