Firefox 技術支援討論區

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

I use to be able to work on one app/window and hover over multiple tabs to obtain brief details on the browser (tabs) as it sits behind the app/window I'm currently working on. Since about a week ago, this feature has gone away. Now I have to be on the browser to be able to hover over the tabs to obtain the info I need on the tabs. I do this to compare the order # that displays on the tabs for what I use it for. How do I get this feature back. I want to be able to hover over tabs to view the small details even when not currently on the browser itself. Please help.

Hello, Firefox somehow crashed. Opening did not reinstall the tabs. This has happened couple of times in the past 10+ years and I was able to recall from History to reinstall the Tabs. Now I don't see that function in the Menu. Please help. I know there is a time limit to re-install them.
