My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

Isisombululo esikhethiwe

Hi Paul, I had already done a forums search and tried the info in your link prior to posting my question (tho not the restoration part as the previous most recent profile was over a year old) - as I said I'd checked my old profiles. BUT I have started my computer this morning and everything is now back! I don't understand this as I had shut down my computer and restarted it a few hours after the update installation, and I had subsequently gone to the 'more troubleshooting information' and the profile that opened was definitely my in-use profile because as i said it showed it had saved these '.jsonlz4' bookmark backups with the most recent being 2 days before the update was installed. So baffled why a second restart this morning after overnight shutdown has got everything back, but grateful.
