Firefox closes and loses all my open tabs with version update

[apostate]

I have opted to keep tabs open / reopen tabs that were open at window close, and this normally works ok. However, (at least most times) when there's a version update that comes with a "Firefox is updated" page opening at startup, Firefox only opens that tab/window and I lose all my precious tabs that were open in the window that was closed the last time I used FF. This has only happened after "Firefox view" was introduced. When this happens, I can never find those tabs in "recently closed windows" - they just disappear without a trace! I can sometimes find them in history, but only for tabs that have been active lately, and still it is a lot of unnecessary work as I can't always remember all the tabs that were open. This is quite frustrating!

It happens with me  three times the last months when firefox is updating in a W11Pro with arm-proc-setting: all my tabs gone. In the past never. I consider after using Firefox for almost 35 years to transfer to another browser, this way it's impossible to organize my things.

Are you able to find them in History -> Restore Previous Session? That always seems to work for me.

There is a specific problem with Firefox 127.0 if you have a Primary Password set and you cancel the dialog at startup on the first run of Firefox 127. If that happened to you, please see this Mozilla Support thread:
