I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

I belong to a number of newsgroups where I save technical data from that is in the form of email. 1. How can I save messages, with header intact, to a text file as I could with Eudora? 2. When I start Thunderbird, what email is loaded into memory?

as described, send tab function does not work one way (android to PC), but works fine from PC to android mobile phone/tablet. the pop-up error is the "Unable to send - RETRY", and pressing 'RETRY' doesn't do anything. I am logged in to the mozilla account on both android devices, and firefox sync/syncing tabs work fine. not sure what's the issue

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

Hi,

I have a user who sends me an email to one of my email addresses and it always ends up in the Junk folder. I've repeatedly marked his emails as not junk but that doesn't seem to change anything.

Is there anything I can look at that will help me figure out why it happens, and hopefully find a way to fix it.

I'm on Betterbird in case that matters. I looked thru the release notes and there seems to be nothing tagged with the junk filter.

I noticed this in the X-Proofpoint-Spam-Details email headers: mlxlogscore=764 clxscore=1015

This person seems to be the only person that has this information in their headers. Is it added by the junk filter? Or is it something on the sender's side (he uses an icloud.com and a me.com address)?

Thanks,

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Reinder

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

Am using 115.10.1 Thunderbird on Windows 10. This email account inbox shows one unread message, but I can't find any unread message. Toggled message threads to see if a previous message was unread, but could not find any there either. Have both closed Thunderbird and restarted the computer, but it made no difference. It is bothersome, but my main concern is whether this is indicating some virus or other hack of my computer. This is just a home computer, not on a business network. Do have it on wi-fi. Is it just a matter of somehow resetting the unread message indicator or is it a sign of something more serious?

Hello, since upgrading to 115 Thunderbird has disabled all add-ons, and does not have an option to reenable them. This was done to several extensions which are not marked as incompatible including "NestedQuote Remover" and "Unmangle Outlook Safelinks". Removing and uninstalling them solves nothing. Indeed, the button to install from the market does not work. I had to save to and then install from a local file to test this.

I am not in trouble-shooting mode, but I have found that "Load Temporary Add-on" in debugging works for the current session.

(I tried searching Google and this forum to no avail.... only turning up irrelevant thread about older versions, Firefox etc.)

Hi!

I'm trying to determine if I'm having a Firefox issue or not. I've been using Firefox for many years and frequently use private windows.

I've got a new laptop with Windows 11 and have been noticing that my private windows are sometimes closing unexpectedly. After which, I can't get my tabs back. This has only happened with private windows, and not regular windows.

Is this an issue that's being reported in the community? Thanks.

Hi, After using Thunderbird for years without problems, I ran into a serious one now (since a few days). When starting Thunderbird it comes up with three almost empty windows, one over the other. No data is filled in and when clicking on the window it says in the upper left corner: Starting page - Modzilla Thunderbird (no response) / (actually in German) Startseite - Modzilla Thunderbird (Keine Rückmeldung). The small login popup is also seen in the window but doesn't accept any typing and shows also 'Keine Rückmeldung / no response'. I can only stop the process on Windows level. I would be very grateful if you could help me with this issue. I cannot get to my emails anymore. Many thanks Holger
