RE: Tab Groups. 1. What will erase saved tab groups unintentionally? E.g. : Clearing Cashe, running CCleaner? 2. Does keeping a large number of tab groups active degrade my computer's performance? 3. Are tab groups saved during back-ups?

App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the Firefox profile folder.

Make sure that you do not use "Clear Recent History" to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

If you use cleanup software like CCleaner then make sure that Session is unchecked in the settings for the Firefox application.

Thanks cor-el (any relation to Jor-El?).

Can you address the issue of computer performance with many stored tabs? I use panorama to store many news stories on a given tab, with many tabs used, so links to hundreds of pages are being maintained at any given moment.

And, as far as backing up the tabs, does the fact that they're stored where they are mean that they will be included in routine back-up?

Thanks again,
