I do, and on multiple machines! Never got any corruption, but that's of course anecdata - also, I don't use the global search/index. I personally don't think it's so terrible - ultimately, the email medium itself hasn't evolved for... never. Definitely the address book is garbage in any possible way (both in the UX, and in the legendary Mork backend) - one has to use addons in order to get a sane experience. Additionally, AFAIK, it's so internally tangled that after years, they couldn't make a tabbed email writing window. Another indicative bit: "Plans existed for Mork to be replaced with MozStorage in Thunderbird 3.0."¹. My biggest worry was actually the addons. There has been a major API change at some point, and several of my addons weren't compatible. Took years for equivalent ones to be developed. Now... another API change (sigh). ¹: https://en.wikipedia.org/wiki/Mork_(file_format) https://en.wikipedia.org/wiki/Mork_(file_format)
