That's how I've always had FF set. Here's the settings for FF and Tab Mix Plus. This issue just started with the update to v18.

Thanks

Check whether your addons are updated or not...

They are all up to date.

I've marked the problem as solved.

Thanks again for the suggestion

The TabMix Plus setting pictured above shows you have selected "Startup Session: Last Session". Change that option. You will need to adjust the settings on the "Session" tabs in TMP; I do not use the TMP Session manager (I use the Session Manager extension instead), you can not use both SM and TMP Seesions, so I can not advise you of the settings. Following is the TMP Manual (there are 3 sections for the Session tab.

OldFox - I've installed the Session Manager and set it to open with my home page. Works so far, so hopefully all is solved.

Thanks to both of you.
