Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

In both my Inbox and my saved email folders, when I click on an end-to-end encrypted email, Thunderbird (v145) displays "Loading Message..." and then blocks with a spinning blue "working" cursor for on the order of 30-60 seconds. The Thunderbird dialog then appears to make some progress, as the windows seems to "flash" as if it's being cleared, but the email content doesn't appear. After about another 20-30 seconds, the encrypted email contents appear, correctly decrypted.

This long delay only occurs when I click on encrypted email messages, and it happens every time I click on an encrypted email message, and this behavior only started occurring in the past couple of days (correlated, I believe with Thunderbird updating to v145) so I think it's safe to assume the issue is with end-to-end encryption/decryption in Thunderbird v145.

I have been using Thunderbird for many years, and it's been a while since I cleaned out my Inbox & Folders. I get about 1200 emails a week, so the clutter is extreme. Yet it is still stable, and now I am waiting to see at what level it falls over. Currently I have 84,544 emails in my Inbox, 131,597 in the Junk Folder,33,718 in Archives, 13,388 in another Inbox, and a whole heap which get deleted when I compact the system.

I reckon compacting it has got rid of another 200,000 or so this year.

I am very impressed, well done guys.

I’m using a decent mid-range phone, and I usually keep only two apps in the recent apps list and a single tab open in Firefox. But every time I switch from Firefox to another app... like the gallery or file manager to upload a file or attach a PDF... the Firefox tab reloads when I come back. This completely resets whatever I was doing on the site, which is extremely frustrating.

The browser feels too memory-hungry and poorly optimized, even when I’m using just one tab. At this point, I’m honestly considering uninstalling Firefox and switching to a different browser, even though I’ve been using Firefox as my default on both Windows and Android for years. I really don’t like the Chromium-based alternatives, but it feels like my hands are tied.

Hello,

I have a MacBook Air M2, and I'm experiencing energy usage issues related to Thunderbird. This has kept happening for a long time now actually, surviving through at least two Mac OS updates, and a huge number of TB updates. Everything's up to date. I tried to follow this: https://support.mozilla.org/en-US/questions/1269944 and this: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems?_gl=1*86dj4d*_ga*MTkzNzQ0MjA3MS4xNzYyOTY4OTMx*_ga_2VC139B3XV*czE3NjMzMTM3NDckbzIkZzAkdDE3NjMzMTM3NDckajYwJGwwJGgw but didn't succeed. Actually, in my case, the issue is more noticeable: I normally have TB open in background - sometimes everything's fine, and the battery goes down as normal, while sometimes instead the battery drops quickly, and checking in the Mac activity monitor I can see that the CPU usage of TB is totally abnormal. When this happens, I can actually see the activity bar in TB being live (bottom right corner, as it happens when TB is checking for new mails), but never disappearing. When I notice it, I just reboot TB, and the bar shuts off as normal after a quick mail check. Moreover, checking the 24hr energy usage by app, TB is often on top with nonsense values.

I tried multiple times to rebuild the database, and do most of the tricks suggested, but didn't fix. Yes I have a huge mail archive, but the problem is not the standard management of this database: basically it seems that every now and then, TB decides to run some activity which it gets stuck in, and this kills the CPU.

Thank you in advance for your help!

I have two installations of Thunderbird on two different computers 2 different locations, both are new installations. Both are on Windows 11. The one at home, works perfect, the one in my second home too except the unified toolbar is unresponsive, whatever I click there it doesn't respond, The X doesn't close the program, the - doesn't minimize anything, just nothing happens, any advise?

BLUFF:

1. Long start up times (do not see this on other browsers) 2. FIrefox often crashes. Browser tells me that a report has been sent. To where? No response. 3. How do I check if my browser is up to date?

What could be causing this? What are my effective actions to increase performance?

Frequently when I hibernate my laptop firefox prevents its (as soon as it enters sleep it wakes up)

when I close firefox it hibernates fine

when I go to powercfg /REQUESTS its the audio card that is driving the wake up

In settings I have turned media.video-wakelock. to FALSE etc and firefox still wakes the computer

I use the Unified Inbox feature and generally keep the Unread filter on unless I'm looking or searching for a specific message. Opening the app or reloading the Inbox takes up to 15-sec to go from a blank screen to showing the messages. I do have all the inboxes indexed on the device but the issue was observed with the standard 25 message limit as well. I have not had similar delays or have been met with a blank screen every time an email app is opened. Is there an ability to speed up the initial and subsequent loading times? It does hamper workflows and skews the perception of the app towards being inefficient or otherwise less than capable compared to similar apps.

when i sign on to my computer, frequently a prompt will appear that says i have to close the old firefox. sometimes i have to close it 5 or more times before i finally get connected to the internet. what can i do? im 83 and not tech savvy. also, when i sign on-the site crashes a lot and i should restart firefox and send a report in.
