I can receive emails fine. But when I attempt to forward an email TB tries using the wrong SMTP server, and an email address that no longer exists in any email account. For example, the email is in a yahoo account and TB tries using a gmail server. I have email accounts (in TB) with gmail, yahoo, rocketmail, AOl, and verizon.net. I have verified ALL server settings for each account as correct. I first experienced this in ver. 140.8.1esr(64-bit), and updating to 140.10.1esr (64-bit) did not resolve the issue.

Hello there,

Using POP3 protocol I receive only the email metadata. It used to work before, it is happening for the last 2 days. See below. It works if the account is created as an IMAP, but this is not what I want. And another thing, it works properly with EM Client latest version that I installed.

Thanks, George

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

There are times that when I open firefox that some of my tabs that does this weird thing where my tabs from the previous session that I left doesn't load up, from what I see is a blank tab that doesn't access the sites I left. It's been twice since I encountered this and I can't replicate the issue. When it happens I try checking out the recently closed tabs or window it doesn't show the ones that didn't show up.

On a new tab page, I have unselected "recommended stories" and added four rows of shortcuts. Almost invariably, when I open a new tab, Firefox has added a couple of new shortcuts, bumping two of mine off the page. The shortcuts I've selected are the ones I want. I would like Firefox to stop making suggestions. Does anyone know if that's possible, and, if so, how do you do it?

Or at least get an expert from somewhere to come up with a solution to people that are not very computer savvy. So frustrating. What is even more frustrating I have no confidence that you will not be able to come up with solution.

Okay, I currently have two issues going on, both repercussions from transferring Thunderbird to my new computer. I'll limit this post to one issue!

My transfer to the new computer was not taking; followed instructions but no profiles were loading. I thought that perhaps this was due to my initial problematic installation of T-bird decades ago, where I eventually wound up with a choose-user-profile panel that worked fine with its default setting...so I lived with that easily (see image). Thinking that this was causing the inability to load profiles on the new machine, I tested whether I could delete the never-used profiles in that panel. After just one deletion, that resulted in the "Couldn't load XPCOM" error described here: https://support.mozilla.org/en-US/questions/1360766 Following the instructions on that page to do a repair installation (to the letter), starting T-bird now results in the attached "profile missing or inaccessible" message.

Please advise: Am I doomed?

Thanks for any honest advice. (yes, my Thunderbird installation is big: seven or eight addresses, many local folders, a large history and archives.)

After briefly succumbing to the ToS hysteria, I decided to switch to Librewolf. It took a while, but I got logged into sync, set up my extensions and copied over my cookie exceptions and custom CSS.

Some of the data that came over from Firefox sync seemed very wrong or out of date, most notably the settings for container tabs. No big deal I thought. I'll just manually edit the discrepancies. Once I had everything set up the way I like it, I looked up a guide on how to sync my current configuration with the cloud and followed the steps.

Phew. Time to watch some YouTube to relax. Problem is that when I finished a video and tried to watch another video, I was logged out and my site settings had reverted to default. I figured the cookie settings were wrong, so I went to the settings page and saw the behaviour outlined in the video I posted.

I've been trying to get this working for over a day now. I've tried resetting Firefox, creating new profiles and doing a clean re-install using "Geek Uninstaller" to make sure everything is removed first. I've tried 3 different forks of Firefox and all 3 of them do the same thing. After I re-install everything, I open the browser and the first thing I do is go to the settings but it's still doing the thing I showed in the video.

The fact that the data on my Firefox Sync is so old has me wondering. Why won't the cloud data update itself anymore? Based on the state of my containers, the Sync data is more than a year out of date. Could there be something wrong with that data that broke my browser when it downloaded?

I'm going to try and get hold of another computer later and try syncing to that to see if it breaks that browser too. I'll update this post when I know more.

Thanks for reading all this.

P.S. I'm typing this using Edge because my Firefox is so badly broken.
