mozilla thunderbird keeps freezing december 2015

I haven't run into problems like yours with 78.*. I suggest you also try running in safe mode (help -> restart with add-ons disabled) for a while.

The only extension I have enabled is 'Display Mail User Agent T,' which is a fork of 'Display Mail User Agent,' updated in late July for Thunderbird 78. I disabled the remaining extensions manually, in hopes that it would resolve this problem, but it did not. Note: As others have mentioned, I found that Thunderbird didn't actually deactivate all of my incompatible extensions. I can at least say with certainty that pre-78 versions have not behaved this way for me in the last few years.

I've been using Thunderbird for many years, and I don't recall it ever behaving like this. Does anyone have ideas on how I can troubleshoot this to determine what is causing it, and hopefully to resolve it? I've looked around, and I'm not seeing other reports of this. This has persisted across multiple versions of 78.0 and continues in 78.1.0. it definitely doesn't happen with every IMAP server call)

I've noticed the freezes multiple times every day, seemingly at random, but thankfully, it's not something that happens every few minutes (i.e. It'll stay there for somewhere on the order of half a minute to a full minute, and then it'll resume working normally, as if nothing happened. When it freezes, it goes into a 'Not Responding' state, no aspect of the UI will respond, and it appears to completely max out one logical core/thread on my CPU. Since it periodically checks my accounts in the background using multiple timers, I don't have an easy way of knowing if the freezing corresponds with calls to one of my IMAP servers or RSS feeds. It can happen when it's in the background or when I'm trying to switch from reading one message to another. It doesn't seem to correlate with any specific action I take. and of course, I lost all of my extensions and their associated capabilities.Īlong with that, though, Thunderbird has been randomly freezing on me. I know a pinned topic says to avoid Thunderbird 78 until 78.2 is eventually released, but my copy unfortunately updated before I saw that.
