For me, it's the extension that is the problem. I can composet weets with tags on the ritetag site but if I move away and use the Buffer extension, Rite Tag does not fill in. It did before.
Hi Saul,

I'd like to add this too. I use Macintosh with Firefox. I want to upgrade to a paid plan but unless this and the firefox extension work properly then the service suffers.

Kind Regards
Still doesn't work for. Removed it, reinstalled it etc etc. Very tired of this add-on - although partly I think it's because Firefox keeps upgrading so quickly.

Wanted to upgrade from the free model but I cannot if this is the user experience.

Regards
Matt, Try quitting Firefox and rebooting your Mac, that worked for me. I completely uninstalled the older version of the add-on installing again. It should work after that, I'm on Firefox 32.0.2, OSX 10.9.4. 
Hi Saul,

I don't know what happened since I posted this apart from closing Firefox and rebooting my machine. Whatever, it is fine now as you said. Sorry for the inconvenience.

Please close as appropriate.

Regards

I would like to add that the current version does not work at all on Firefox 32.0.2 running on Macintosh OSX 10.9.4
