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.)

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.

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 what means: Flags: firefox-backlog+

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