Backward compatible session manager

On PC, I used to use the addon Session Manager : It creates files that go by the extension ".session", and I have a folder with very many of those.

I don't know if up to date session managers work with the same file type, or whether it's a standard. I am looking for an addon that can at least read and open them. And preferably, that one can save and process sessions in this file type, to keep some continuity with my old profile. And still better, some cross browser session manager, so I can open those old files in, say, chrome too.

You are asking about this in the Firefox for Android support forum. Do you need a hand with this on Firefox for Android or are you using a PC?

On PC only. Sorry.

Would the mods move the thread, or should I repost at the other forum?

The old Session Manager extension for Firefox 56 and earlier used its own folder for its data files. Extensions based on the WebExtensions standard cannot do that, they could only access that folder when specifically directed by the user (for example, using an Open File dialog). So while you could probably import some of those old files if needed, the newer extensions can't work with them on an ongoing basis. The newer extensions either use a database or create folders full of bookmarks.

These are the session management extensions I'm aware of that you might investigate/try out:

Use database storage:

Use bookmark storage:

Bookmark storage is more robust in that Firefox backs it up regularly. However, having the extra data show up when you are searching your bookmarks may be annoying.

The .session file format is very similar to the Firefox 55 sessionstore.js file format, there's just a little extra metadata. So if you need to convert them, it shouldn't be too difficult. If you want an HTML page of clickable links from one of those files for your records, you can try my Scrounger page:
