I don't have the same experience as you with FF and nothing like losing what I type ever happened to me. That would indeed be nasty bug and make it very unreliable/untrustworthy. It's possible you have something corrupted? Try a reinstall or try on a new machine and see if you can replicate the bug? I'm not 100% with Firefox but it's really the least bad option to me. I found, for example, quite irritating how FF was playing shenanigans with the new tab/homepage settings, eagerly recommending things I never asked for but luckily I was able to disable that. So far FF is quiet, not obnoxious and working.
