I'm not sure if I picked the right topic but am guessing my problem would fall under settings. The last few days I am having a problem replying to emails; when I go to click "send" to reply I get an error and it says failed to send. The only way to send a reply back is to compose a new email with my reply in it; send works every time if I do it that way. Hoping someone has the answer to why this is happening because I have no clue where to start.

Thank you for any tips, ~ Kathleen

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.

For the past few days, I have been having problems with using Google apps and websites on Firefox. Gmail is very buggy, often not allowing me to search past emails, restarting on its own, and generally being very unstable. I've also experienced problems with Google Maps and Drive. These problems are not happening on other browsers like Microsoft Edge. I have tried clearing my cache/cookies, and using troubleshooting mode, but that did not solve the issues. I use Google a lot, so I will need to turn to another browser if I can't get this fixed. I've used Firefox for years and would love to continue to do so if there is some way to address this issue.

Being in a rush after a botched TB update from v120 to 140.0esr, and missing disk backups, I reinstalled v102 and recreated two of my four email provider accounts in TB 102. Now. I'd like to try the update again this way: 1. export the few messages downloaded to the reinstalled v102 2. Completely delete v102 and any traces of TB on my C: disk (Program Files folder, user account folders, registry...) 3. Install the latest version (143 as I write this) 4. Copy and set as default (or import?) a two-weeks old disk backup of the old TB v102 profile into v143 without anything missing:

   - Four email accounts
   - All the messages in all the mailbox folders (received, sent, drafts, etc.) of these accounts
   - The complete archives folders structure and content
   - All the other folders I created as direct children of the email accounts in the TB "Folders" outline and their contents
   - one RSS feeds account and its settings
   - ~40 RSS feeds subscriptions and their settings

5. Import the recent messages from step 1 into the corresponding TB accounts.

Is that the correct way to do this?

I'm wondering about a few things:

   - Best email export format for later import?
   - Will the restored email accounts automagically reconnect to the provider accounts? I may have changed the format of one of them from Imap to pop3, and the server handled it very well, but it would be Imap again in TB after restoring the disk backup...
   - Why is v140 the only one with ESR in its name and not the following ones? I was on ESR when I froze 102 and blocked updates)
   - Is the Sqlite DB part ot the TB account file structure, and is it carried over when moving or duplicating that account?
   - Has the TB account folder and/or the Sqlite DB changed format between v102 and v143?

P.S. the email account for this post is among the inactive ones at the moment!

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

Posted this in Google Play Store reviews and was told to post here:

Frustrated with latest update to the download UI. When you save an image for example, the Download Progress and Download Complete pop-up can be swiped away to hide the pop-up before it naturally fades, but the area of the screen it occupied remains uninteractable for a period of time anyway. If you try to tap anything in that area, or swipe to scroll a page by starting the swipe in that area, nothing will happen. It's as if the pop-up is still there, just not visually. Hoping this gets fixed.

Additionally, it seems awkwardly difficult to swipe away the pop-up as well, requiring almost an entire screen width of swipe to make it properly disappear.

On Sunday October 5, 2025 I began experiencing an issue with gocomics.com. I thought it was a temporary one that would resolve itself. Monday morning it was still happening. I contacted GC thinking the issue was on their end. They were unable to replicate it. They asked me to try to go to the site using the private window on FF. I was able to access it just fine. Therefore, we know it is not GC. I was also able to get to their page on Chrome.

I tried again on Tuesday. Same issues. I had already read on some forums where others were getting the same loop that I am: https://amub2c.b2clogin.com/amub2c.onmicrosoft.com/B2C_1A_GC_SIGNINSIGNOUT_POLICIES/oauth2/v2.0/logout?post_logout_redirect_uri=https://www.gocomics.com

It was suggested to try refreshing FF. I did that. Didn’t work. Gave up again for the day.

This morning, I tried uninstalling FF. Didn’t work. What else is there left for me to try?

I HAVE TRIED TO FIND A STREAMLINED WAY TO DELETE MULTIPLE DUPLICATE BOOKMARKS (UNINTENTIONALLY CREATED BY AN OLDER FIREFOX BOOKMARKS IMPORT). BUT I HAVEN'T FOUND ANYTHING THAT WORKS. USING BOOKMARK MANAGER IS FAR TOO TEDIOUS AND TIME-CONSUMING. AND AN EXTENSION ADD-ON I TRIED CREATED EVEN MORE PROBLEMS. I NEED HELP!!

I have been trying to filter out and delete emails with certain URLs in the HTML section of the body of the message.

I can get the Body filter to activate and delete the email if I send the specified URL within a simple text message. So the Body filter can activate on sequences in the text part of a multimode or simple text email.

It doesn't, however, seem to activate for the thing I truly need, which is to see a URL (or other sequence) in the HTML part of a multimode. It appears to ignore the HTML section.

Would it be possible to either:

1) allow the current Body filter to scan all parts of a multimode message? OR

2) create a new filter, perhaps named Rawbody, or Raw, etc., which doesn't break down and separate the parts of a multimode first, but simply does a raw scan of the entire body: text, HTML, and all?

Thank you.

I am running Windows 11 on a Lenovo ThinkPad. For years, my firefox has opened to us.yahoo.com without a hitch. A day ago it started opening to that page once, then not again. It looks like it trying to do, but something blocks it and it ends up on a blank screen. I can get to yahoo if I then type in the address. I have checked and the home page is set correctly. I have refreshed Firefox several times. I uninstalled it, and re-installed it. It still opens to a blank page. I am running Windows standard security stuff.
