I typically have 2 or 3 windows open, with 3 to 8 tabs in each window.

But if I've opened several new tabs and they're loading simultaneously, I might expect some of them to load slowly, but I don't expect them to crash the application. They are more likely to happen when I am right-clicking on multiple links within a given page in order to open linked sites in new tabs. Firefox has offered no pop-ups explaining these sudden shutdowns. However, all my other Firefox shutdowns over the past several days have not been associated with a snap refresh being needed. I was able to do the refresh and re-open Firefox. Internet search brought me to several web pages which explain that a sudden shutdown of Firefox when I need to do a refresh is a consequence of the move from apt to snap for which the end-user experience is terrible. One - but only one - of these shutdowns may have been associated with the need to do a sudo snap refresh. In none of these shutdowns did I get that bug-report prompt. Previously, if Firefox (or any other application) shut down unexpectedly, I would expect to get a pop-up stating that the application had shut down unexpectedly and asking me if I want to send a bug report to Canonical. It has shut down without explanation at least 6 times over the past 4 days.

Unfortunately Firefox has been very unstable since this upgrade. I am now using Firefox 105.0.2 (64-bit), Mozilla Firefox Snap for Ubuntu canonical-002-1.0. When I rebooted after the upgrade, the Firefox icon had disappeared from the Favorites dock, so I had to go into Activities to launch it. While this upgrade generally went very smoothly, a pop-up paused the process to tell me that henceforth Firefox would be packaged via snap rather than apt. Four days ago I upgraded my laptop from Ubuntu 20.04 LTS to 22.04 LTS.
