I won't be able to recreate all of this from memory after darn styling in support.mozilla.com destroyed my reply.

I tried Firefox (5.0) File menu to import Opera (11.50) bookmarks and that failed, it was supposed to show checkmark list of what I wanted it did not, but continuing it said it was successful but did nothing.

Next I tried import of Opera bookmarks directly through Library list in Firefox since that was an option there to -- that failed to work as well.

This is what was successful.

((I didn't but then I know what I was looking for anyway, but still would be better.)) Add two bookmark separators at the very end of your Bookmarks Menu (one of the 3 main folders) so you will see where the Opera bookmarks get added.

backed up my Firefox bookmarks

Ctrl+Shift+B > Import and Restore > Backup >

c:\temp\bookmarks-2011-08-13.json so they can be restored if anything goes wrong, and I had bookmarked a few items (perhaps 3) today.

Create exported bookmarks from Opera, I had to select Bookmarks in opera bookmarks list, and choose bookmarks not Opera as folder

File > Import and Export > Export Bookmarks as HTML >

c:\temp\from_opera_2011-08-13.html -- (I think bookmarks here means the main folder, if that is correct that's cool because in Firefox there is no selective export only all)

verified that the HTML file was a valid file containing all of the bookmarks from Opera

Then in Firefox

Ctrl+Shift+B > Import and Backup > Import from File >

c:\temp\from_opera_2011-08-13.html

Bookmarks were added to the end of Bookmarks Menu the first folder added was Opera then Bookmarks -- looked good, but don't want them so selected everything from first folder added to last bookmark added with select then Shift+click to select through the end and deleted them (you select to left of folders and icons so you don't invoke them).

There is also an answer to your first post of this question: https://support.mozilla.com/en-US/questions/861013
