I was using Firefox on my work laptop until it started freezing while using salesforce.com. It seems to have started around the time v13 came out but i can't say for certain. I've attempted to remedy it by disabling all plugins but that did not help.
Thanks for the suggestion. However I've gone as far as uninstall, delete all saved data, and reinstall. I suppose it must have something to do with my machine but I'm stuck on what that might be. Are there any tools you are aware of to troubleshoot?
