When bulk selecting and deleting, sometime columns don't match rows. eg: subject doesn't match correspondents (sometime additional random contacts are added to correct correspondant) and message panel may not match highlighted "subject" email.

Been using for years...love the product. But this is a new quirk. I have noticed, when I have done hundreds of bulk deletions, deleted messages will be added back in inbox??

Thanks, dmillert@aol.com

Firefox keeps stopping on my Android; in fact, it won't even load. I have tried clearing the cache and clearing the storage, but that has not solved the problem. If I uninstall and reinstall Firefox, is there a way I can save my bookmarks? I don't think I am currently signed into (or registered for) Firefox Sync. I am hoping it might be possible to do that from my laptop. The bottom line is I really don't want to lose my bookmarks if at all possible. Thank you for any help/ guidance

Hi I have a couple of http only pages behind a VPN in a private network. When using Firefox for Android and entering the address, either with "http://" or no prefix, Firefox is not able to connect and instantly switches to "https://" mode. "HTTPS Only" mode is not activated, DNS-Over-TLS is also deactivated.

The page can be opened when using the IP address.

In private mode Firefox opens the page as expected.

All other apps on Android do not show this behaviour, i.e. Chrome for example opens the pages fine as expected.

With Firefox on Linux, it works fine.

How can I make sure that Firefox openes the HTTP page and not switch to HTTPS.

About:config is disabled in Firefox on Android so all tweaks changing the settings there do not work.

Tried this with and without plugins, no difference.

'bold text YouTube is "acting insane, sound plays/picture is frozen. Can't pause it. Also can't start it! Ads play on without option to skip. I got some notice that YT was changing something, I think it is broken. I managed to get a video to play on MS Edge, but I normally do not use that. I cleared cache and ALL of that, rebooted computer, etc. connection is good. Searches are fine on firefox, Other sites are fine on firefox. . IT IS YOUTUBE! It is SO bad that now with my mouse, the arrow and hand are NOT showing up on the actual screen where video plays. Right now on here it is fine. but on youtube? no.

I deleted an email account ***@gmail.com I am no longer authorized to use. I persistently receive Google "Verification" screens for that email account. These only appear if I have thunderbird running.

Every time I start up Thunderbird, I receive a "Please verify" message from Google (see screen shot). This message refers to an email account that I deleted because I am no longer authorized to use it ["s***@old****.com]. These requests also turn up regularly if I remain connected. I cannot verify the account because the password has been changed and the verification email is no longer mine.

I have 2 other accounts on Thunderbird; one is linked to a private domain; one is an ***@gmail.com account. Both perform correctly; are configured correctly and cause no problems with passwords, etc.. Other evidence:

In Box: The s***@old****.com account is not present in the left menu window. When I go to Accounts, Settings: The s***@old****.com account is not listed. When I go to Server Settings (In or Out) there is no trace of the 's***@old****.com' account, although the other two accounts have correct settings in the 'Outgoing' server.. Previosly, this email "s***@old****.com" was also linked to my Google Account. I have deleted it from my Google Account; I have deleted it from Thunderbird as an Account. When I disconnect my Google Accounts: This has no apparent effect on frequency of Verification prompts [I close my Safari browser]. When I Close Thunderbird: The Verification prompts for "s***@old****.com" no longer appear.

It seems like Thunderbird is still trying to "Get Messages" from "s***@old****.com" and triggering the Google password protection system (?).

IS THERE A WAY TO FIX THIS IN THUNDERBIRD?

Thanks, Al

Today (4/27/2026) I am suddenly unable to log in to My Account on various websites (eMail, grocery store...) The business page opens but when I try to go to the account login page, I either get a blank page or the page spins and spins and never goes to the login page. I am able to get to the logins on Safari. I've cleared cache and cookies, and closed out of Firefox and reopened.

If the VPN is open in one user account on a given computer, is it functioning on all accounts on this computer? I have difficulty turning the VPN on when using one user account if it is already on in another user account. Seems to be a conflict and I don't know if it is even necessary.

How to delete preference to always store Passkey on device?

What happened: 1) I wanted to create a Passkey for a website and store it in Bitwarden. 2) Bitwarden pop-up opened, but while exploring the options, I accidentally clicked on the option "Use your device or hardware key: Always for this website". 3) Windows Defender dialog popped up with the options "iPhone, iPad or Android device" and "Security key" 4) I backed out of the dialog window 5) I clicked the button to create a Passkey again but going forward only the Windows Defender pop-up appears

The problem: I now cannot create a Passkey to store in Bitwarden on a specific website, because I accidentally clicked on "Use your device or hardware key: Always for this website".

What I've tried that didn't work: - looking through Bitwarden settings - deleting Firefox cookies - doing the same thing in Private Browsing - asking AI and looking through about:config, about:preferences and about:logins, as well as trying to find profile files related to webauth

Found workaround: - creating the Passkey from a different Mozilla profile

I would still very much like to be able to undo the "Always for this website". Is there a way to do that? (Attached images were captured later when recreating the situation.)
