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.

No matter what setting I choose , ie dark or light, all the websites are showing dark. This is a real problem for my eyesight. I cant see words etc. I have tried various changes and have reset dark/light but still dark. can anyone help with this please

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

Firefox extensions are exhausting my CPU like a malware (it seems like it...) and i can't figure out which one is the problem

I want to edit my auto-fill data, I suspect it may have errors. How do I get to see and edit the auto-fill data that has been entered into my browser? I have looked and can't locate this info.

Autofill keeps bringing up an old email address as a choice when logging onto website accounts. When I accessed 'Autofill' under 'Settings,' there was no choice for email addresses (see circled area on photo). Is this not a feature, or am I in the wrong place? If this isn't a feature, I would like to suggest this addition.

How do I get Firefox to show page information when hovering over a tab on the Firefox tab bar? It did this until one of the recent updates and now that doesn't work and I can't find anything in settings to control this feature.

Hello, My Firefox recently updated (it's now v. 138.0.1), and now I can't seem to create tab groups anymore. When I move one tab on top of another, nothing happens. What can I do to get this useful tool back? Thank you!
