STR: 1. Install Jetpack: https://addons.mozilla.org/en-US/firefox/addon/12025 2. Restart Firefox 3. Open one tab at about:jetpack, and another at any URL (e.g. about:blank) (The second tab is just for triggering a session restore prompt) 4. In Add-ons manager, disable Jetpack. 5. Restart Firefox. When prompted if you want to save your tabs, choose "yes". ACTUAL RESULTS: When Firefox starts up next: - I get an alert message saying "The URL is not valid and cannot be loaded." - The tab that was at "about:jetpack" is now blank, and its title is "Loading...", with no favicon. (though nothing ever loads) - If I restart Firefox again (without closing this tab), the same thing happens in my next Firefox session (and every session thereafter, until I close the tab). EXPECTED RESULTS: - Ideally, no alert should be shown (though perhaps that's ok on the first session restore after the addon-disabling) - The tab header should show "(Untitled)" (like an about:blank tab), instead of "Loading...". - OR, the invalid tab could just be excluded from restoration altogether.

SECOND EXPERIMENT: Instead of "about:jetpack" in step 3, use this URL: chrome://jetpack/content/NONEXISTENT_PAGE.html Note that (when Jetpack is enabled) this gives you a "File not found" page, with a warning favicon. As before, disable Jetpack & restart Firefox, with this tab open. ACTUAL RESULTS FOR SECOND EXPERIMENT: - No alert is shown (presumably because the URL is valid) - However, I still get a blank tab titled "Loading...", this time with a warning favicon (moz-icon://stock/gtk-dialog-warning?size=16) -- the same favicon that was used Jetpack was enabled.

Note: In both experiments (comment 0 & comment 1), Firefox's Location Bar is blank for the restored invalid tab.

I've reproduced this bug in both mozilla-central trunk & Firefox 3.5.5. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.3a1pre) Gecko/20091125 Minefield/3.7a1pre Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5

One other way to reproduce this bug: - Close the "soon-to-be-invalid" tab before restarting Firefox (making sure to save your session). - After the restart, use Ctrl-Shift-T (or use History | Recently Closed Tabs) to resurrect the tab. --> BUG (same actual results as in comment 0 / comment 1) ALSO: Once you've reproduced the bug, you can trigger it over & over, without restarting, by simply closing the "buggy" tab and then resurrecting it with Ctrl-Shift-T.

The tab title is nowadays "Problem loading page" and instead of an annoying popup we luckily have about:neterror that shows a page with a "try again" button. Let's consider this fixed.
