OPML Support for Firefox
Note: watch the OPML Support section of my blog for information on updates to this extension.
OPML Support is an extension for the Mozilla Firefox Web browser that adds OPML import/export functionality to the Firefox Bookmarks manager. OPML is a file type that is widely used to distribute lists of RSS/newsfeeds.
When exporting, you can choose to export your livemarks, bookmarks, or both. When importing a file, you can choose to import only the livemarks, only the bookmarks, or all of the links listed in the file. You can also choose whether to import/export links in their folder hierarchy.
The latest version of OPML Support is version 1.5.2.
If you're having trouble with the extension, e-mail me at cfinke@gmail.com or leave a comment below.

I really like this extension, but was wondering if it was possible to add functionality to export / import selected Bookmarks / Bookmark Folders. This would be a great feature that I'm sure a lot of people would use.
Thanks,

I was using this extension some time ago, but it lacks proper accentuation support. There's no way to fix this?

Appeared to install fine but now I'm guessing it doesn't work with OSX 10.3. Recieving an error message (file size) when I atttempt to upload the file.

I agree with the ability to export some bookmarks, either selected, or even by folder.
Great extension.

I know this is a "quick & dirty" approach, but the OPML file is a text file that you could open using any text editor and cull out the feeds you don't want. MS users could open it in Notepad or WordPad, and just delete the lines containing the sites in which you've no interest.
Yeah, it's manual labor, at that point, but... Waaaaa. Cry me a river.
It works and you've already got the software to do it; no downloads required.

Doesn't work anymore (at least under firefox 2.07).
Tries to download a 4Mb+ file and fails with a -71 error code after a couple of seconds.

Any plans for an update so it works with the current Firefox version? I'm eager to try the extension (and I'm surprised OPML functionality isn't built into the live bookmarks to begin with!)
Thanks!

liberrian: I'm working on it right now; most of my other extensions are FF3-compatible, but the bookmark-related ones take a little more work.

Hey, when will you be putting this update in the official Mozilla Firefox Add-ons directory. Your version there is still at 1.3. I only truly trust extensions from the Add-on directory.

I'm getting a failed due install message,
Not a valid install package
-207
anyone else, or should I be looking at the system?

The plugin doesnt work with 3.0b5.
It just crashed the browser.
I know you don't list support for this version yet...but thought I'd make sure you know support would be appreciated.
This is avery useful plugin.

This bookmark extension does not display (therefore is not available) with Firefox 3.0 iMac version 10.1.5

I use FF 2.0.0.14. I installed OPML Support 1.5 and it appears in my Add-ons list. But there is no way to start it. In the Add-on list the field for OPML Support shows a greyed-out OPTIONS button, and all I can do is either disable it or is greyed out, and all I can do is either disable it or uninstall it.
How can I start using it?
Thanks for your efforts

OOPS! Just correcting the text of my post of a few minutes ago.

Firefox v3.0
When I try to export just the Live Feeds with or without preserving the folder structure it just hangs, no output whatsoever. When I close the dialogue FF stops, so it looks like it's crashing the program.
Does it work with v3.0?
June 20th, 2008 at 6:27 am
I'm using Firefox 3.0, and OPML Support 1.5. I exported my feeds from IE7 as OPML. In Firefox, I used Import OPML, and selected the defaults (create folders as in the OPML file, and not converting to bookmarks) , but it although it said it was Processing the file, it never finished. Nothing was ever imported.
June 20th, 2008 at 5:45 pm
I have the same problem as the previous user ... hang (I guess?... shows the "processing" for the longest time) on import with no result...
June 25th, 2008 at 6:52 pm
HOW DO YOU INSTALL opml?
EMAIL ME @ tmofocus@yahoo.com
July 2nd, 2008 at 5:41 am
Does not work. Same as 24 and 25.
WHY IS THIS NOT BUILT IN TO FF3??
Very disappointing. Oh well, back to IE7.
July 3rd, 2008 at 3:04 am
After having problems with a hanging pc using the 1.5 version I tried the latest experimental version 1.5.2 This caused a Parse failure saying :"an unknown entity"
July 15th, 2008 at 1:13 pm
The OPML import function does not seem to work. It says it's processing, but then it hangs.
July 21st, 2008 at 4:04 am
(Re 27)
Thanks for fixing this Chris! 1.5.2 works ok.
(Still think it should be built-in though.)

Hi,
I'm having trouble importing an IE7 generated OPML file. On both Mac and WinXP and in both the latest versions of FF I get the following error msg: XML-parse failure: Undefined entity Location: chrome://opml-support/content/import-wizard.xul Row30, Colomn 3:

Any suggestions.

"Erreur d'analyse XML : entité non définie

Numéro de ligne 33, Colonne 3 :
----------------^"
This is the error I have when I try to export my bookmarks
(FF 3.03fr, Vista64 ult, opml 1.52)
In fact I installed OPML trying to fix a bug with my Mozilla : the native 'HTML export" fonction does not work anymore (since around a month)
I still can export to the json format but I can't import this save so I am stuck...
If anyome has the same problem and an idea...
