Hi everyone... can you give me some ideas of what kinds of things I should be looking for that might be causing frequent "lockups" in Tbird? I see it only when I'm trying to get something done, obviously, like composing an email or replying to one, for the most part, but also when trying to work my way up the new emails (I generally read them from oldest to newest.) I'll hit delete, and nothing happens, and there's no response to mouse or keyboard input. Most often, it just stops responding while I'm typing. I'm a touch-typist, and when I look up to check for errors, the thing is frozen at a line previous, then it suddenly fills in what I typed while it wasn't responding. I'm running version 102.10.0, and Linux Mint 21.1 as my O.S. I know there's a .json file that would give a lot of info about Tbird, but I don't know which one it is... let me know and I'll post it, if it's needed. I just migrated from Windows 10 to Linux exclusively... had it with Windows nonsense. Tbird ran flawlessly at first, but the lockup issue is happening more frequently with time/use. Any ideas of what might be a likely culprit would be greatly appreciated!
