In the last couple days, I am not receiving messages in my email account inbox (att.net/yahoo). Messages are going directly to the local inbox folder. Windows 10.

When I search for new emails in the local folder, they are tagged with a gold diamond, and my option is to "Move to inbox again," which does move the messages back to the main inbox. But, "again" implies that the message arrived in the account folder, but got automatically passed to local folder. On or two occasions, I noticed an very fast dowloading to the inbox, which disappears immediately.

And, I get no response in my email account when hitting F5. F5 works for the local folder, and other accounts, and Shift-F5 (getting messages for all accounts) updates the others, but not my main email account.

The issue is not with att.net/yahoo. I have checked all my settings and server settings in Thunderbird, done the folder repairs several times, closed and reopened Thunderbird many times, deleted Inbox.MSF, etc., but nothing works. The issue seems to be specific to Thunderbird. Any ideas?

I use POP. I download and keep all my messages received and sent, and have the server delete after a set period. However after installing Thunderbird I've noticed my sent folder is only 6 months old. It should be 15 years! What has Thunderbird done with my messages and can I get them back?

I changed POP3 email password to an app password and Thunderbird would not recognize it even though I updated in Security. I was told to delete the Thunderbird account then set it back up which I did--I did not check the box to delete files. Finally the new account was able to bring in new emails (POP3) but the old folders/emails are not there.

I read that I should go to %appdata%, roaming, Thunderbird but the dates are from years ago--do I go further to find my data or is there another path or something else I should do?

Unless they were backed up somewhere within Thunderbird, I don't think I have any backup.

Can you please help? Thank you.

I am using Firefox 157.0.1 (64-bit) on Windows 10. When I browse papers on https://www.sciencedirect.com(https://www.sciencedirect.com) and click the "View PDF" button, the page that opens is completely blank. The same PDF loads normally in Microsoft Edge.

I have already tried troubleshooting steps: I cleared cookies for this website and disabled Enhanced Tracking Protection for [sciencedirect.com](https://sciencedirect.com), but the blank page issue still exists.

Thank you for your attention and assistance.

I have not been able to log into: http://www.kerncountylibrary.org after having able to do so for the last decade. When I attempt to open the site to log in, Firefox asks me to choose a file to open the site. This has been happening for the last several days.

AVG sends message: "We've identified a site certificate problem" "Trust for this certificate has been revoked."

Looking at certificate page that AVG provides is Greek to me. General tab displays:

"This certificate has been revoked by its certification authority"

issued to : inbound.att.net

issued by: Digicert Global G2 TLS RSA SHA256 20250 CA1

Valid from: 4/12/26 to 10/28/26

Details tab:

lists a bunch of things that I don't comprehend and offers an option to "copy to file" and lists a number of formats to copy the file to.  Have no idea which would be the one to use. 

Trying to access email directly from browser has not been successful because it wants verify my identity by sending message to my phone, but it does not send anything.

After a recent update my bookmarks toolbar appears blank. It is shown, but empty. When I go to the bookmarks menu I find all of the bookmarks shown as being on my bookmarks toolbar. How do I get them back where they belong?

Hi, I have a shortcut which comes up with a blank icon. I've tried Google help to use a custom picture, but nothing worked. The complication is that my shortcut does not go to Xerox, it goes to their pension provider who has a different name. The shortcut works fine but it would be nice if I didn't have a blank icon.

I have no accounts, no old emails, nothing.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

In Thunderbird, the “attach” button stopped working when sending a message, although the “drag and drop” feature still works. Could you suggest what the problem might be?

Hey,

When I was using Firefox version 156, the free Firefox VPN was active for me. However, after updating to version 157.0.1, the free VPN no longer appears, so I cannot use it.

I use Bookmark Toolbar a lot. It has several menus, with submenus. But when they layer over top of each other, I get lost in which layer I am on and too often my mouse moves off the top layer, which closes it.

I would like to somehow change the colour of the menus, depending on the layer. Currently they seem to all be kinda grey, regardless of theme.

But if the first dropdown menu could be yellow and then the next be blue ... or whatever, it would be most helpful.

I suspect this is something that could be effected in userChrome.css, but I have no idea what to put in there to target the menus.

Any help or guidance you can provide is much appreciated.

Thanks!
