Firefox in safe mode not remembering tabs, refusing to login to servers
Im having some serious problems with firefox. I have saved the %APPDATA% folder.
I cannot login to mozilla servers for firefox sync and whenever I close firefox it would only remember the tabs and windows I opened the previous day; not today's tabs. It runs for over 1 hour saying it's working on sync.
When I login after reinstalling firefox all my tabs are removed and cannot get sync data. How do I fix this without removing my windows and tabs (have over 100 open). I want to keep all history and tab data. Also tried cleaning cookies and cache data; no luck.
It looks like I have been having sync problems for a week, based upon my logfiles; but it was only today it stopped restoring new tabs and windows (old ones work).
Regarding the session restoration problem:
Could you take a look at another recent thread about the latest session not saving completely, resulting in an incomplete restore? It's not solved, but I wonder whether your Browser Console shows the same kind of "not enough memory" error: https://support.mozilla.org/questions/1324995
Regarding the slow Sync problem:
I think Sync runs in the background so it doesn't interrupt your ongoing use of the browser. Is your browser very busy doing other things? Otherwise, hmm... nothing is coming to mind.
