Whenever I restart firefox, the last tab I had opened does not load. The matter of restarting can be any kind: new add on installed, new firefox update, restarting the browser manually, or restarting my computer so that firefox is automatically closed. It's always the same problem. The last tab will be displayed as my New Tab page, which is blank. I can have 3 tabs open, and the first 2 will load just fine, but the last doesn't. This means that if I restart for an add-on or something, I need to go back into my history to pull up this last tab, which is inconvenient. And it may not have been my most recent tab. I may open this last tab, go back to an earlier tab and surf the web on that, building my history, and then restart firefox for whatever reason. In those instances, I need to open up the history window and dig for that last tab from memory.

Are the other tabs pinned tabs?
Firefox will always open at least one normal tab.
You can check this setting in Options:
- Firefox/Tools > Options > General > Startup: "Don’t load tabs until selected"
The "Don’t load tabs until selected" setting toggles the browser.sessionstore.restore_on_demand pref on the about:config page.
There is a browser.sessionstore.restore_pinned_tabs_on_demand pref for pinned tabs that isn't affected by the setting in Options/Preferences.
These tabs are not pinned tabs.
It is also not the Don't load tabs until selected setting (it is unchecked). It loads the unselected tabs - when I switch to them, they're already loaded. The tab it focuses on, the tab furthest to the right, can still be a New Tab that has replaced the active tab on the far right.
Just found this one out. Left my computer in sleep mode without a charger while it was on low battery, and it turned itself off from low battery. This crashed Firefox. Upon restarting, Firefox gave the prompt that it couldn't automatically restore the last session. It listed my 4 tabs in Window 1, complete name and all. When I clicked the Restore button, the first 3 listed tabs loaded, but the 4th did not and instead a New Tab was in its place.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
Alright. It appears to be an addon called Load Tabs Progressively. I'll just leave that disabled.
