Don’t know if you are aware of this but in Firefox you can open multiple tabs automatically when the browser starts – kind of like homepage on steoroids. You do this by separating the URLs with the pipe character (|) in the list of homepages in the options (on the General tab in ToolsOptions…). I use this a lot if I found some information I do not care bookmarking but I’ll need the next day.
There seems to be a problem with this feature however. When reopening the browser the tabs will not expand and show the page titles (see screenshot below) until I close one tab. After researching a bit it turned out to be caused by the otherwise excellent Tab Mix Plus extension. Disabling the extension removes the issue. Hmm….
The issue is on Firefox 1.5.0.3 and Tab Mix Plus 0.3.0.5 on Windows XP SP2.
