The 5sk9c5pl.default-1487690735779-1530305829750 profile got created June 29, 2018 after a refresh (reset).

If you do not have an "Old Firefox Data" folder on the desktop and the other profile folder (prorjmbh.default-1487690735779-1523479659903) doesn't contain any files then it sounds that something went wrong with that last refresh.

Did you notice any hangs when that refresh was in progress?

You could try to use an undelete utility to recover files in that prorjmbh.default-1487690735779-1523479659903 profile.

You can look at this utility to browse System Restore points.

"Old Firefox Data" folder on the desktop is created automatically ? and is hidden file ?

No Hangs when refresh was in progress

Do undelete utility will restore the whole system or firefox only ?

The "Old Firefox Data" folder on the desktop should be a normal file and not a hidden file, so you should see it if Firefox has created this folder following a refresh.

In some cases it can happen that the transfer to "Old Firefox Data" fails and also the original profile gets lost. I don't know why an update would cause a refresh to happen.

Hi, glad found it.

Never work with original files, only copies. Work with Firefox closed.

What's What in the Profile :

• bookmarks and history: places.sqlite
• bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
• cookies.sqlite for the Cookies
• formhistory.sqlite for saved autocomplete Form Data
• logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
• if you only have key3.db then make sure to remove an existing key4.db
• cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
• if you only have cert8.db then make sure to remove an existing cert9.db
• persdict.dat for words you added to the spelling checker dictionary
• permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
• sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)

Sorry for late reply ...I will do as you told and let u know .....

I rename the Profile which was in "Old Firefox Data" to currently profile name " xxxxxx.default " .Delete the Firefox Profile in the Roaming location and paste the rename Profile which was in "Old Firefox Data" in the following folder.

C:\Users\usman\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxx.default

Then i saw all my crash profile back again :-)))))).....After 6/29/2018 (After 2 months)

Thanks every 1...

I need to ask 1 more thing .

Do i have to copy xxxxxx.default to Local location also ?

C:\Users\usman\AppData\Local\Mozilla\Firefox\Profiles\xxxxxx.default

No, do not copy any data to "AppData\Local". This location stores temporary data like the disk cache and thumbnails (about:newtab) and phishing protection data. All important personal data is in the "AppData\Roaming" location.

Note that it is not advised to rename a profile because some files might contain references to absolute locations that point to the previously used profile name. Best is to only copy files that contain data you really need or edit profiles.ini and set the recovered profile as the default profile.

This sounds like two symptoms of the same issue: history not working normally.

Do you want to start a new thread? This one is two pages long already, which reduces the amount of replies you will get, and most of it is not helpful in understanding your current problem so it will waste a lot of reading time for volunteers to continue here.

You really should start a new thread.

Where did the old history file come from and how old was it? There may be permission/privilege issues affecting whether Firefox can update files from a different Windows user, and the file format changed in Firefox 56.
