Hello. I love the feature. I didn't know it was a new feature because I started using Firefox around April. I saved my group tabs, very happy about it. Then I close and save it, then I opened it again, it was great!

I am a student, I use my group tab to add the tabs that have the resources that I need to, and would also like to study for more knowledge and for my next school year.

There was no problem at that whole time. In April 21, there was no problem until April 22, 23 no problem. But I forgot my charger at that time, because I was at my mothers house. Then I wait for weeks for my charger to come back, about 2 weeks for my laptop to revive there in my grandparent's house.

When I got my charger, and opened firefox. Wait, but at first when I opened firefox, it showed me that there is a new update, an update about tab groups that I already now. I looked at my group tabs, and they are not there anymore.

What should I do to get them back.

How can I get this side bar to re-display automatically upon opening Firefox as it used to in previous versions?

I have Firefox ver. 138.0.1. Since this update I can't find a way to open my bookmarks on the sidebar and keep it there. I can open it by going to View-Sidebar-Bookmarks. But I have to do this every time I sign into my Firefox. I like working with my bookmarks open on the left side all the time. I am sincerely hoping the update did not do away with that feature.

Hello,

Last night my computer asked me to install an update (not sure if it was Mac or Firefox whose upgrade it was). Although when I restarted, it's closed out all of my firefox windows (does not allow me to restore session), and all of my book marks are also gone.

Is there any way to get these back?

Thanks so much!

Why is the sessionstore.jsonlz4 generated from a private firefox window ? It is not private anymore if the session is stored in place of the regular session, which by the way happens not to be generated when the regular firefox window is closed while a private firefox window is still open. The private firefox window should have no effect on the regular session storage and should never be stored, all this is very confusing.

Hello, I recently had 20+ tabs open in Firefox. I moved 1 tab of the 20 to be a separate page and closed the other tabs. Now I am unable to re-open the other tabs through the 'Recently Closed Tab' feature. That feature only shows a few new tabs I opened on the separate page. Is the only option to painstakingly search through history over several months to re-open several tabs I had open for several months? Thank you the feedback, Ken
