I-Firefox Community Forum

I am trying to recover a FireFox session from a backup of my C:\ drive from a few months ago, but I am blocked by "access denied". No matter what I have tried, access is always denied. I an using FireFox version 149.0 on Windows 10, and am trying to manually make the substitution in the folder C:\Users\...profiles\318tzbcg.default-release\sessionstore-backups.

I have tried the substitution with FireFox totally shut down (checked in Process Explorer) and even after a reboot. I am blocked from copying any of the current files to another folder or to rename them (as a precursor to (hopefully) replacing them), much less over-copying them with files from my drive backup.

I have tried from an this with CMD (run as administer) in my normal user account (which has admin privileges anyway) and with an actual Administrator account. In my User account I have verified for the properties of the Profile and sessionstore-backups folders that all of the accesses are ticked as allowed for write and read (except Special Access is not ticked). The section with the tick boxes is greyed-out (with those boxes checked), and I cannot untick any of them or put a tick on Special Access.

(I am writing this from a different machine, so have not clicked the Share Data button (troubleshooting information) on this submission form, but can provide that later from that machine,)

What can I do to get the needed access (permissions) to substitute a recovered sessionstore.jsonlz4, recovery.json4lz or previous.json4lz file?

So far hate new Firefox that I have been forced to switch to - very annoying and such a waste of my time trying to sort out my bookmarks. May make me switch to Edge or something.

Followed the instructions - C:\Users\name\AppData\Roaming\Mozilla\Firefox\Profiles\ - found a backup but no information as to how to get the bookmarks into the new Firefox?????

Many of us are older users and perhaps not so savvy as to how to do this.

And so it would have been nice if Firefox could have been more "nice and be specific" with this forced change over.

Thank you

Hi, ok, so my computer just randomly updated my Firefox Browser and now all of my bookmarks, saved passwords, extensions, themes, and history is gone. I used the links on the support website, but they were not helpful at all. I am logged in with the same account I was originally logged in with prior to update 149.0 (logged in with gmail). When I sync data in settings, it automatically imports my Safari and Chrome information (which is not what I want). I try to import my bookmark and password history from the saved HTML and CSV files under Mozilla Firefox, but I don't have the ability to do so, as the files are essentially 'greyed' out. I have tried every step to troubleshoot and every link that is related to my issue listed on Mozilla's support with no success. I have even searched my issue on Google and Reddit. Please help!!
