1257848 - Firefox forgets URLs from several tabs when restarting

Status: RESOLVED INCOMPLETE

(Firefox :: Session Restore, defect)

Description

[0RUBn0]

Attachment: Firefox forgets tabs URL.jpg

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160303134406

Steps to reproduce:

Restart firefox, jump to tab from previous session.


Actual results:

The page tries to load (shows turning waiting icon), but ends up empty because the URL is empty in the address bar. SO, it probably just loads an empty page.
The icon of the previous page that should be shown, is still there, but not the URL.
This happens to several tabs that I kept open.
(By the way, tabs are not reloaded by default until i click on them in my configuration.)
This has happened for a while now. Probably already since previous version of firefox (maybe not the version before that.)


Expected results:

The URL should have been remembered since last time that tab was closed.
This way I al losing very important tabs that I left open on purpose for later reference (for my job, private, but important stuff).

Correction: ...icon is still there, until I click on it. SO, the icons of the other tabs are visible untill I click on it.  (But the name says "New Tab" from all such buggy tabs).
In the attachment, at least 5 buggy tabs are shown. The ones to the right of them are all OK, but I don't know about the pinned tabs, since I can't read the text. Sometimes they are buggy too.

Small addition: It seems that it is always the first one or few tabs from the session (or group) without gaps. Sometimes it's only the latter (on or few).  (Maybe it's relevant to where I was last time, since it often happens that I am on the first or last tab when quitting firefox, or maybe it really is just from start or end absolutely. Dunno,  but it seems relevant for the bug pinpointing.)

0RUBn0, does this still happen when using the newest version?
