When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your help!!

While this note is probably the wrong way to ask for help for which I apologise, I am moving from Seamonkey to Firefox and Thunderbird. I have managed to get Firefox to work but don't know how to get my Seamonkey e-mail moved to Thunderbird.

If some kind soul could point me to a place or person where I can get detailed instructions on moving my e-mail from Seamonkey to Thunderbird, I would be incredibly appreciative. Again, I know I am probably asking this question in the wrong forum, but I have tried everything I can think of with no usable result. I ask that whoever reads understands getting up in years is frequently a difficult process. Oh yes, I go back to the early Netscape days as a user.

Thanks, in advance, for any and all assistance.

After auto update this error message came up and will not allow Firefox to open. Earlier in the day it had also updated ( not sure to what version) and was working fine. Laptop was then shut down and turned off for aprox. 1 hr. I then turned it back on and tried to open Firefox and it again asked to allow Firefox to make changes to my computer to which I clicked Yes. It then would not open and this error came up. error message Platform version 127.0.2 is not compatible with minVersion >=127.0.1 maxVersion <= 127.0.1

I need to create a pdf file to share with an agency in another country that does not have Firefox. I am unable to create a simple pdf - all of the files are automatically Firefox pdfs. All attempts to convert this file to a regular pdf have failed. Please help!

Hi,

Progressive web apps do not have the option to install, just "Add to home screen".

For example, https://whatpwacando.today/

Related, it does not support the browser event beforeinstallprompt.

Thanks, Paul

This is a repeat of a problem that I posted a couple of weeks ago. I am unable to log in to my New York Times account on Firefox (other browsers work fine). I have reset the password several times but it still doesn't work. I had a response to my previous question that led me to disable Total Cookie Prevention for that site. Thereafter the Times seemed to work properly and I stated that the problem was fixed. However, the fix lasted for only a short time and it is again acting the way it previously acted--I can't get past the first page to the full stories. There must be something else at work, but I have no idea what.

I occasionally get a Authentication Failed to Server (Outlook.com) and when it occurs it continues for 1-5 minutes then goes away again.

Is there any error logging proceedure that I can set up to see what the exact issue is?

I've tried running a parallel alternative email client (eM Client) and that doesn't seem to suffer in the same way, but I much prefer Thunderbird so would like to find out what the problem is.

I tried to change the font-size of address bar, tabs, sidebar and toolbar using the method given in The method given in: [https://support.mozilla.org/en-US/que.../1239467] gives no change at all of the font-size no matter the value I use. Any ideas? I'm using Windows 10 Firefox 127

Similar to this post: https://support.mozilla.org/en-US/questions/1417523

This issue is only on two computers (24" iMac running Sonoma) - others at the client site work normally.

Client has up to date Firefox (127.0.2 - also tried latest ESR) full screen with multiple tabs - config set to use system print dialog by default. Print - print dialog opens, print is sent. Tabs are now greyed out, cannot type in text boxes. Changing context (opening and closing About Firefox) restores normal function.

set up a new profile - same issue.

Any suggestions?

I have been using sandrawhitfield@comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered whitfieldsandra@gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered whitfieldsandra@gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the whitfieldsandra@gmail.com account. Would appreciate any help you can offer.

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!

Since downloading latest update, requested by the software, it takes 2 or 3 times longer to go to most websites, but it takes 10 times longer to go to a Youtube video. (Generally 10 to 30 seconds).

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

With about 60G of accumulated e-mail in several Microsoft accounts, I moved all accounts into T-bird and put most in local folders. This somehow became over 600G in size. Everything works and compacting seems to be getting done since it's been working some weeks now. Yet this ten-fold increase in size is unwieldy and very difficult to backup. Perhaps related, I notice that M'soft's "new" free Outlook app is present and perhaps running on this computer. And all the e-mails I send from my main Hotmail account are listed twice in the T-bird sent folder. About half of the times I start T-bird, I get a message saying that login to server outlook.office365.com with username xxxxxxxx@hotmail.com failed; the other accounts never do this. T-bird offers to retry, but that usually ends with a repeat of the same message. I've learned that if I let it open, with time, the e-mails do appear, though I don't know how or why. I've also been using Libreoffice successfully for months now though I doubt that anything to do with this. T-bird nicely solved the original e-mail oversize problem I had with Microsoft's size limitations and I'd appreciate advice on how to deal with what's happening.

Hello,

I am new to Thunderbird and need help with configuring the 'Copies & Folders' tab in Thunderbird 115.12.2 (32 bit) running on Windows 10.

Background: I have just set up a pop3 account to download and locally store all incoming messages to my inbox and also to keep a copy of those messages on the server.

I want to store all sent messages for that pop3 account locally too, in a 'sent' folder.

Questions: 1. If I have more than one pop3 account set up like this, do I: (a) set up a separate 'sent' folder for each of those accounts; or (b) set up one 'sent' folder containing sent messages for all pop3 accounts, or (c) is it personal choice?

2. How do I set up: (a) a separate 'sent' folder for every pop3 account? (b) a single 'sent' folder for all pop3 accounts?

3. Can I keep a copy of all sent messages on the folder in addition to storing the locally; and if so how do I configure this?

4. How do I set up the Drafts & Templates section for the above scenario? My preference here would be to have one drafts folder for all pop3 accounts. I don't use templates.

5. If I uncheck the 'keep message archives in' check box, will that turn off automatic archiving and keep all incoming pop3 messages in the inbox?

6. Is there an up to date manual for Thunderbird? I can't find one.

Many thanks for your help with this.

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?

I have a <something> that creates a daily sunrise and sunset entry time in my diary. It isn't an addon as far as I can see. It's not a prewritten list, but seems to create its entries dynamically when I first look ahead to a date- filling all the days with the correct sunrise and sunset times. The normal reoccurring event options don't appear when I delete one. i.e. doesn't offer me the option to delete all the events. I have no idea what I did to set this up ( it must have seemed a good idea at a time). I can not see any subscription that would account for it. I've checked all my accounts on my devices. Thunderbird/Betterbird on my main PCs and Outlook.com on my iPhone just in case I brought it in to TB that way ( which seems unlikely). Nothing. Clearly something is working away generating new sunrise and sunset times to display in TB. But I can't find any way to kill it off. I must have found a sunrise/sunset app that does this, but I have no idea how or where. Any suggestions. Either where it might be hiding in TB or where I can track it down and look for instructions.

I have accounts for my husband, sister and daughter as well as myself. Lately when I try to access my emails I keep getting messages to enter the passwords for these accounts. I have never had to do this before. I don't have passwords for them and don't even really know how to do this.

Also my emails are very slow. I was waiting for a link to a podcast and the email with the code took a little over five hours after the podcast before I received it. This has never happened before.

Help. Gail
