Status: RESOLVED WORKSFORME

(Firefox :: Session Restore, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5

I noticed this a while ago, but thought it was a gmail issue (since that is the tab I usually close out on).  After several weeks, I noticed that when I close on other tabs, the same thing occurs.  

I have ff load my windows and tabs from last time.  This was working fine until recently (I believe with the latest update, but I can't be certain).  Now all my tabs load fine, but my last active tab will not load.

As a temporary workaround, I can load an extra tab with nothing on it before closing, so I won't lose the information.  The "untitled" tab does not give me the option to go back to the page I was on.

Reproducible: Always

Steps to Reproduce:
1. Use FF as usual, with multiple tabs.
2. Close browser.
3. Start FF with option "show windows and tabs from last time" activated.

Actual Results:  
As described above, all tabs load except the tab that was active when FF was closed.

Expected Results:  
All tabs should load, including the last active tab.

Can you reduce this to a small test case? (if you have important tabs, you can make a backup of sessionstore.js FIRST - this is the important one for you)

Start a new session, open a couple tabs, do a little bit of navigating, then quit. Make a backup of that sessionstore.js, then start Firefox again. If that last tab is untitled when it shouldn't be, then could you upload or email a copy of the sessionstore.js (the backup, pre-reopening Firefox).

In addition, it'd be worth trying Firefox in safe mode (http://support.mozilla.com/kb/Safe+Mode) to see if an extension is to blame.

If you're willing to try one more thing. Next time this happens (if you haven't used your workaround), try closing that last tab, then reopening it (though history | recently closed tabs)

Is this still happening?

In addition to the suggestions in comment 1, you could also try a clean profile (firefox -profilemanager), reinstall your extensions, and see if the problem still exists.

If it exists, post a list of your extensions -- the problem might be with an extension or interactions between sessions.
