User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:32.0) Gecko/20100101 Firefox/32.0
Build ID: 20140825202822

Steps to reproduce:

I exported the bookmarks from Firefox v32.00 to a json-file. After that I started Semonkey v2.29 Beta 2 Build 1 to import this file. 

Actual results:

The file-open-dialog will be opened and after selecting the file, an error occured with "The backupfile could not be imported". See attached screenshot.

Expected results:

The json-file replaced the present bookmarks.
Guessing that you're seeing this?

Bug 942937 - Deprecation warning "PlacesBackups.getMostRecent is deprecated and will be removed in a future version" in nsSuiteGlue.js (port bug 859695)

Note that you cannot import any .json backups, not even SeaMonkey's own.

(SeaMonkey 2.26.1 is able to import.)
The error occure also if I import the json-file from Seamonkey. Errormessage was "Filetype not supported"
Summary: Import json-file from Firefox do not work → Import json-file from Firefox (or even from SeaMonkey) do not work
rsx11m pointed out that FF is also affected, & it is, so moving to Core.
Likewise, suppose the bug I pointed out is not the issue at hand.

can you please send me by mail the json file you can't restore into Firefox?
This is my .json-file from Seamonkey v2.29
Attached file bookmarks-Firefox.json
Here my Firefox v33.00 Beta 5 Build 1 .json-file
Will import, bookmarks-2014-09-13.json
Will not import, bookmarks-2014-09-20.json
Screenshot - Diff
I have two .json in my /bookmarkbackups/.

bookmarks-2014-09-13 - Copy.json
bookmarks-2014-09-20 - Copy.json

13 will import.
20 will not.

I did a s/{/&\r/g on them to try to make them a bit more readable.

I notice that all lines begin with a quote (") except lines 30 & 31.
Suspect that something not kosher is going on there causing the import to fail.
(Let me also just mention .json vs .jsonlz4.)
looks like on of the 2 has a bookmarklet that maybe it's not well escaped, this "Target new windows" bookmark.
The lvermark loadfailed and expiration should also not be there as well, they are not real items from a long time.
so will this problem ever been fixed in a forthcoming Version??

It means it is part of our Product Backlog and is a bug we can schedule for development in an upcoming iteration.

I believe this was fixed on the SeaMonkey end by, Bug 1116446 - Cannot restore bookmarks from backup JSON file.
