I look over this more today and it seems that this not only affects Ubuntu systems. It seems that this affects slow computers, generally, those that are using a hard drive. Here are my testing results: * tested on 3 Windows 10x64 machines with SSD and the importing for the same number of bookmarks happens almost instantly. * On a MacBook Pro with macOS 10.15, 11, and 12 installed I cannot reproduce the issue on either of the operating systems. * I tried importing on an old laptop with Windows 10x64 installed HDD and Windows 7 installed on HDD and it seems that the importing takes more time (~15 to 25 seconds) for the same number of bookmarks as on other previous tests.

Also, I saw some crashes on my Ubuntu 20.04 station if I closed the migration window and Firefox before the process was completed. This is intermittent and I don't have some to reproduce. Here are the crash report: [crash1](https://crash-stats.mozilla.org/report/index/ac28897c-1fc3-4076-892b-bc8b10230330), [crash2](https://crash-stats.mozilla.org/report/index/99d303c0-b434-4542-b396-af6910230329), [crash3](https://crash-stats.mozilla.org/report/index/370f6f7e-f5fd-4886-b633-fedd90230329).
