App tabs and panorama wiped out at restart:

Your question appears to be a continuation of something else, but this is your only post that I see here.

As you say you found app-tabs are part of your browsing history, so you don't want to wipe that out.

It is important to close Firefox properly through File > Exit or "Firefox" button > Exit, since you are on a Mac it may be slightly different. In Windows do not use the "X" in the upper right corner which closes the Window but not necessarily Firefox.

See item #31 in the following, basically if you don't see what you wanted from the previous session, use your History menu to retrieve previous session and then possibly previously closed windows.

You can make Firefox 6.0.2 look like Firefox 3.6.*, see numbered items 1-10 in the following topic Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6). Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.

There is a lot more beyond those first 10 steps listed, if you want to make Firefox more functional.

App-tabs can be closed and they can become contaminated with unwanted History within the tab. I would suggest you maintain a folder of bookmarks that you can repopulate your tabs at any time by opening the bookmarks in the folder into tabs. You can use the Multiple tab handler" extension [https://support.mozilla.com/questions/846422

The Multiple Tab Handler extension provides lots of features for handling multiple tabs: pinning a selection of tabs (app-tabs), pasting titles & urls in various formats. Closing selected tabs, or all tabs to the right/left. Closing tabs to the right is especially useful if using app-tabs.

If you want to test out the functionality of anything involving Tabs use this test page. (the strange name is derived from my keyword shortcut to the page is "_")

Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.

Thanks, but that doesn't really answer my question. A prior poster had a similar problem. The first solution offered to the poster was to make sure that history wasn't being cleared automatically - this doesn't seem to be my problem. The ultimate solution was :

It is also possible to use the "Show my windows and tabs from last time" setting, that is usually a more reliable way to restore session data.

   Firefox/Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time" 

But in 602, there is no such thing as Firefox/tools, or tools/options. Is there a way for me to utilize this 'show my windows and tabs from last time' feature, or has that disappeared? thanks for any help!
