Session restore after crash used to work, but during my recent crashes, I get about:blank instead of about:sessionrestore.
Additionally, a problem Mozilla Firefox is having for more than a decade: Session recovery failure.
They have made it worse by adding a layer of bulk (euphemism: “lz4”), which does more bad than good. (if it ain't broken, don't “fix” it).
My question is: What exactly causes Firefox to fail recovering the session?
I know about Session Manager (only for Firefox pre-Q**nt*m) and TabSessionManager (for Q*a**um), but the latter one unfortunately is close to useless.
Reviews state: “WHY CAN'T THE OLD SESSION MANAGER BE UPDATED TO WORK ON THE NEW FIREFOX??” (user 79323d, 6 days ago via https://addons.mozilla.org/firefox/addon/tab-session-manager/reviews/) Another review: “Literally nobody asked for IndexedDB. The legacy way (storage.local API) worked perfectly fine. No need for GarbageDB!” (by user e3fa12, 19 days ago)
I am using Windows 8.1 at the moment. I have not experienced the session recovery failure on Linux so far, and it used to work fine for Windows 8.1, even with 500+ tabs. But somehow, recently, it stopped working.
