Modern browsers allow me to keep important things like passwords, bookmarks, etc. synced up in 'The Cloud'. I mainly use Firefox and Chrome.

However, I'm unaware of a way to sync the changes I've made to the browser's dictionary. Every new computer I use I need to teach my style of spelling.

Are there any plugins, add-ons, or other ways of achieving what I want?

sorry but did you mean the one browsers use to correct our typing? nor known to such sync service that browser provides then.

but if it is file-based, some symbolic link and service like dropbox may help.

#actually I use dropbox to synchronize my firefox profile across 3 computers. (they won't be running at the same time, so I don't have to face the conflict problem. )

Yes, I mean the dictionary in the browser. I'll clarify my question to reflect this. BTW, the Dropbox solution is a pretty good idea. I would prefer to have an extension mind you. – boehj Sep 21 '11 at 4:44

Chromium and Google Chrome added the feature to version 26. The feature is available in Linux, Windows and Chrome OS but not Mac OS yet:

To do it manually:
In Chrome the user added spellings are stored at C:\Users\XYZ\AppData\Local\Google\Chrome\User Data\Default and look for Custom Dictionary.txt. (It will only be present if you have a custom spelling entry)

Then sync it with your cloud service using Symbolic Links.
