I'm an IT consultant trying to help out a poor client of mine who suddenly has been getting tons of nasty profane spam. Her email address must have gotten on somebody's bad list because this just started happening after years of relatively little spam. It comes in huge bursts.

We had turned to Thunderbird because it was supposed to be good at isolating spam. But no matter what I do, it won't move ANY spam to the Junk or Bulk folders. Yahoo uses Bulk so I told Thunderbird to use that folder. I also told it to use SpamAssassin. It is EXCELLENT at marking all these emails with the little symbol for SpamAssassin, but it doesn't automatically move them. And there's no rule system that can move them. I've tried it at the local level, account level, every possible setting, and the old ones stay in the Inbox and the new ones go directly to the Inbox. I've even turned off antivirus to see if that was interferring.

I really don't want to give up Thunderbird, but this isn't working and it's the reason we came to Thunderbird. Can anyone shed some light on this?

New update 140.1.0esr broke connection to my AOL verizon email (##@verizon.net) Apparently AOL mail will not accept the password or something. Have tried lots of things (including 2-12 hour chat with AOL mail "tech support"). Exactly same thing on my wife's desktop install. I considered trying to roll back to previous release - but I had both set to not install updated without asking permission. So I assume if it roll it back it's just going to update again without asking for permission. HELP! I've spent at least 6 hours on this already.

Please help! I have tried all the top level fixes, checking permissions, restarting, all the settings, advanced and otherwise. Troubleshoot mode. I have not reinstalled the instructions file - forget its name... is that necessary/useful? Or is there a way to find code that is overwriting improperly. It's not just for what I write now, wherein an attempt to, say, make a specific word appear blue fails. But what is stored and read through thunderbird also loses its color-switch.

Thanks.

I have Firefox configured with auto-expanding vertical tabs. Sometimes, when the mouse cursor leaves the Firefox window through the same border where the tab bar is located, the tab bar expands and stays in that state until the cursor returns to the Firefox window. This is especially annoying with two displays; if the cursor hovers over the tab bar right before moving to the second display, the tab bar remains expanded, overlapping part of the browser content.

Hello Last year, I first saw the icons in the far right top corner of home page (red 'X' and other orange one) kept turning grey. Now for several months the entire top 'task bar' area of Firefox home page constantly turns grey, then back to regular color, back and forth, in the most aggravating way. I tried all suggestions: disabled hardware accelerations, disabled themes and extensions, cleared cache.... Still persists. I just noticed it may occur mostly when more than one tab is opened, even just two. Has anybody else encountered this? I use Firefox as my only browser-- on a Toshiba laptop. Thanks.

Emails from certain senders (big companies like Amazon, Twitter and YouTube), after having been received normally for some time, suddenly stop arriving. They are not in a junk folder and nothing I have done has been able to get anything into a junk folder.

I also receive emails on my phone, and the problem messages ARE in a junk folder there. (I only just realised this.)

The problem seems to be that Thunderbird sees some messages as junk but instead of putting them in a junk folder it disappears them completely. From the evidence on my phone, nearly everything being flagged as junk is real email, things I want. If I could simply tell Thunderbird to receive everything it would be fine, but I don't know how to get these emails to download.

Looking at what is in my phone I see a load of important stuff that I really need, in my junk folder there. It's not anywhere in Thunderbird. How can I get this to download?

Good evening! After updating the update to the latest version of Thunderbird, the address book stopped working. Reinstalling the program did not help, rolling back to the previous version - swears that changes in the profile do not allow the application to run. Deleting abook.sqlite, abook.sqlite-wal, and abook.sqlite-shm did not solve the problem. After deleting all the files, logging into the program and trying to create a new address book, nothing happens, only these three new files are created in the profile. The address book is local

Since 141 update I have constant problems with youtube. Page does not load at all or loads only partially. Icons on sidebar are broken, youtube logo is black. I tried disabling ublock and greasemonkey but it did not help. Refreshing page multiple times and using ctrl+f5 sometimes helps but issue returns often, every few videos/visits. Clearing cookies helps but only for few hours and then issue returns.

Is it related to WebGPU support that was supposed to be added in 141? Can I disable it somehow?

I can no longer update or install extensions on my Firefox profile.

When I attempt to update, nothing happens. When I attempt to install a new extension, the Mozilla page states "Installation aborted because the add-on appears to be corrupt."

This appears to be a problem with my profile, because if I create a new profile, I can install extensions with it. However, I do not want to lose my existing extension settings or data.

About two day ago my U Tube started not showing the normal size player but it shows one similar to the picture in picture. The sound is working fine. This is happening all three of my WIN10 computers when I use Firefox. If I go to MS Edge or Opera the U Tubes run just fine.

I hate both of those browsers and have used Firefox for years but I use U Tube a lot and I need a fix.

I am thinking that the latest Firefox update was about the time this started happening but I am not sure.
