Recently Google has added offline support to its popular service Gmail. Its really a nice feature which allows me to read and search email while travelling or when squirrel has cut my broadband connection's wire. While offline support is working fine in Chrome( google's own browser), my firefox started crashing with it. I predominantly use firefox so little disappointed that offline mode is not working with it. It is still in lab feature so may take some time to be fixed for firefox.
What has been your experience with offline mode in Gmail?
