I've been using Firefox for 15 years, both on PC and Android. Recently, when using Firefox, I noticed that when I quit Firefox, the corresponding entries in the timeline are no longer deleted. You can see this under the setting of the recently closed tabs. A complete deletion should have taken place after the complete termination of Firefox. Unfortunately, this is no longer the case. I use a Galaxy S26 Ultra with the latest Android releases and also the latest version of Firefox from the Play Store. The setting of my Firefox instances is always such that when you stop Firefox, the timeline of open tabs, the history of open tabs, is always completely deleted. Can you help?
