I’ve had no problems at all with Firefox – didn’t even know there were compatibility issues – but suddenly I’ve been getting the dread message that EF can’t save the page I’m looking at. Multiple sites today.
I don’t have Default Folder X, and can’t think of any recent software change that would have caused this.
I just transferred my bookmarks over to Safari. What a drag. (I found the alternative bookmarklet solution confusing: when it prompts you to open the page you’re looking at in Firefox with an application, what does it want – Firefox? EF?)
