I am using TB 140.4.0esr (64-bit) on Kubuntu 24.04.

Noticed with `top` utility that there is 40-50% CPU usage by thunderbird process. Spike starts every minute and continues for about 30 seconds.

Turns out, if you are using Blogs and News Feeds feature (RSS), TB tries to update some feed every minute. And if feed is inaccessible, I guess, it tries to do so for ~30 secods, then timeouts.

I subscribed to some blogs years ago. Now couple of them disappeared unfortunately.

When I paused updated for certain feeds, CPU spikes has gone.

Hope this can help someone.

Ich nutze viele Konten in Thunderbird (Android) und auch auf dem Desktop. Problem bei Android: bei jedem Aufruf muß der gemeinsame Posteingang neu abgefragt und aufgebaut werden. Damit ist die Verwendung kaum mehr möglich. Auch das löschen von E-Mails funktioniert so nicht mehr sofort und sichtbar. Wann wird das geändert und so indiziert, wie bei Thunderbird für Desktops?

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

My Thunderbird (version 115.12.2) is running on a Windows 11 system. My profile has multiple accounts configured as IMAP to multiple email services. I also have the Status Bar and Activity indicator enabled. Randomly, both indicators will show busy for an extended period of time. When I view this in the Activity Manager I see one or more folders hung for 10 or 20 minutes downloading one message out of several. This occurs in multiple accounts and servers.

I have researched this and attempted the fixes presented. I have cleared the cache files and compacted and rebuild email folders as suggested, but the slow update still occurs.

Then I decided to try and capture a ProMon.exe trace to see what is happening. What I found was Thunderbird.exe was spending all of the time while hung access the following file: C:\Users\MyUser\AppData\LocalLow\Intel\ ShaderCache\4a5eb0e65e559fc08e65ecb2fa9d650817ae895582a7a7ede162866d3e47a05a, like it was stuck in a loop.

When Thunderbird is operating normally, it is accessing this file but only for short period of times. Research says that it is ok to delete the files in this folder. I did that and it seemed to help for awhile. But it started happening again.

Does anyone have any idea what could be causing this? Is there a Windows thing to look further into? Any help would be greatly appreciated.
