Firefox bookmark questions

Factual Questions
1

I bought a new computer last year when my old drive died. I took the non-responsive SSD to a shop and they managed to make a copy of the C drive for me. I copied over all the files I needed and kept the old info on a USB stick. I imported my old Firefox bookmarks to the new computer. I deleted a couple of old bookmark file folders that I thought I didn’t need. Turns out I was wrong and there are a couple of Internet sites I would like to view again. Try as I might I cannot find the right search terms to locate those web pages.

I inserted the USB drive and located the old Firefox backups from last year and copied the most recent onto my current C drive. But how do I view that file to find a couple of web sites? It is a JSONLZ4 file. If I click on it Firefox does not open it. Text editors do not work. All I want to do is view and search in it.

All I can think of is to run Firefox and have it import the complete old backup bookmark file, locate and make a note of the sites I want and then restore Firefox with today’s backup file. Is there any other way to have Firefox open the old bookmarks without overwriting the present bookmark files?

You can use a tool like this: Firefox Bookmark Backup Reader/Decompressor — Fx File Utilities

Drag the JSONLZ4 file into it and it’ll open it for you. You can either read the raw code to find the bookmarks you need, or export it to a variety of formats (like HTML for Firefox re-import).

Or if your bookmarks aren’t private and you want some help, feel free to DM the file to me and tell me what you’re looking for and I can grab it for ya.

Disclaimer: I’m 75 with erratic memory issues, but…

I had the same question a couple of years ago and IF memory serves I solved it by creating a second User Profile in Firefox and then importing the backup JSON file into it.

JSON is an archival format that is both machine and human readable so any text editor can handle it. But .lz4 is a compression format like .zip so you need to use a program to handle that first, it;s not human readable. .jsonlz4 is Mozilla’s combo and handled like the other posts suggest.
