I'm facing this issue since Firefox 3 and Google Toolbar for that has been released. when logging in with my Google account or clicking a star on the toolbar, I see an error message on the error console. that says,
Cc['@google.com/toolbar/bookmark-wrapper;1'] is undefined
I don't know what happened, What I can tell is this feature worked on Firefox 2. so trying to google it and amazingly there are so many people who is facing the same problem and there are a lot of false alarm about its solution, at least with Firefox 3 or on Fedora 9.
- installing libstdc++.so.5 would helps.
Apparently it's not. the latest Google Toolbar doesn't even require libstdc++.so.5. but surely libstdc++.so.6.
% readelf -d extensions/\{3112ca9c-de6d-4884-a869-9855de68056c\}/components/libgoogletoolbar.so | grep libstdc
0x00000001 (NEEDED) Shared library: [libstdc++.so.6]
So this wouldn't help at all.
- that works fine after creating new profile.
That didn't even help me, unfortunately.
So I have given up to investigate this issue and just installed
GBookmarks add-on. I'm happy with it now.
[Update: 2008-07-22] Google toolbar 3.1.20080605L works fine on Debian sid, but Iceweasel 3.0.1. I'm missing something or something went wrong. I'd believe Firefox and Iceweasel doesn't make so much difference. anyway Google toolbar doesn't work yet on Fedora 9.
[Update: 2009-09-24] I have to update to not let people get confused... Once updating to Google toolbar 5.0.20090823L (I'm not sure which version exactly fix this since but anyway), this feature works fine again on even Firefox 3.5.
