Hello,

my firefox browser is registered to my old email address "mhesky@hotmail.de". Because of an hacker attack i had to delete this email address. My new email address is "Hesky85@outlook.de".

My problem is, that i cant change the email in firefox because a confirmation email will send to my old email address that doesent exist any more.

How can i change the firefox account to my new email address?

I need help please.

Regards Michael Hesky

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.

There used to be an option before, but now it just always pops up. It is never useful for me and constantly switching to offline mode or using some other account first is a pain. There is no button to continue manually.

I just purchased a new PC. HP OmniDesk Slim model with Intel Core 13, Win 11 home version, 8 GB DDR5, 512 GB SSD. I just read a previous article, "Move Thunderbird data to a new computer." When you make the move, does it also bring your account settings with the move? And by the move, I mean copying and pasting from old PC to new PC. Or do I enter this info manually? I am moving data from old HP w/win 10 originally installed, to new HP w/win 11. I also read a previous article on forum, "An alternative method for manual transfer between Windows 10 and Windows 11 computers." This was also included in this article. "This section assumes you have a default Windows installation and will work on computers upgraded to Windows 10 from previous Windows versions." My old computer had win 10 originally installed, not upgraded, (as stated above). Any info/help you can offer will be deeply appreciated. Thanks

Hello everyone. From time to time, the "Attachments" button stops working. It can be clicked, but nothing happens. Occasionally, restarting the PC or the email client helps. More often, the only solution is to reinstall the entire program—which also means losing access to years' worth of emails, as I then have to wait for them to be re-downloaded from the IMAP server. What should I do? I’m using the latest versions.

this issue started when firefox just randomly reset my browser a week ago.

whenever i open a pdf in my file explorer, it opens a completely new firefox window under my default-profile. it doesn't open on my currently open/used window.

for context: i have two firefox profiles, 1 for work, and 1 is the default-profile which is "personal"

anyone know a possible solution to this? or why this happened?

Hi, I would like to install Thunderbird on my computer to connect it to my Wanadoo account. What are the settings: IMAP, ...? I also want to install the folder structure on another drive to avoid loading my system drive. What other things should I be careful about to avoid making mistakes or wrong settings or security ? Eventually, I would also like to add another Gmail account or another provider. Thanks in advance

I have been opening and closing my VPN(different website), but now it won't let me do it. I did what it said to get started and then it tells me to open in the open site. Where do I find the open side? I used to press the VPN shortcut in the upper right corner and it usually worked. Now it just asks me to "Try firefox VPN. I thought that is the one I was using. How do I get it going again.

I use middle-click to close the tabs and move and select tabs around a lot and often misclick on a button by accident and I find that really annoying and tedious to always have to scrutinize the buttons before clicking.

I want to hide all of these buttons.

I have tried userchrome and etc... user scripts, that does not work reliably.

HI started getting the message that i couldn't go to websites I refreshed and then uninstalled and reinstalled Firefox browser Now i get the following message no matter which site I try to access

The connection was reset

An error occurred during a connection to www.youtube.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

thanks Chris Jamieson

Firefox locks up and crashes on Win 10 desktop after it Firefox updates. If I refresh Firefox it seems to work OK for a couple weeks until Firefox updates . Then it becomes unuseable again. I have refreshed firefox twice now. Should I get this ESR version?

Whenever I use FireFox to watch Twitch, majority of chat just never appears until I refresh the site... It was working good until some month ago...

I use the extension BTTV to get extra emotes on twitch. And it was working perfectly, some say that is the issue, so I removed it to test, but still FireFox is not loading all messages... What can be done to fix this? Just use another browser?

Since today's update to esr 153.5 a lot of things have changed for the worse. One annoying thing is that Firefox always opens now in Minimised view...why? I've never used Firefox Minimised...so now every time I have to click Maximise. Another one was that the Hamburger menu items suddenly had huge spaces between everything...at least I was able to find someone on Google who had a css to fix that. But the same thing is happening in the right click menu also, I had a css for that for years but now that doesn't work. The other super annoying thing is the scrolling has totally changed, I always used to uncheck 'smooth scrolling' and check 'autoscrolling', although I never use what they say autoscrolling is supposed to be about...something about holding the middle button on the mouse?? All I know was that setup used to make the scrolling in Firefox excellent...now it's basically annoying smooth scrolling whatever I check or uncheck. The other thing is after this happened I uninstalled Firefox altogether, and reinstalled the 150.0esr version and all this stuff is the same...even though I was previously on 153.4esr...and it wasn't happening on that? So I suppose I might as well just update to the latest one then? And just put up with all this annoying stuff. By the way, I'm still using Windows 10...not one issue a year after all the doomsaying from Microsoft [Defender still gets security updates anyway?]...which makes me wonder about the so-called 'security' issues with using an older version of Firefox. Thanks, any ideas for ways to fix these things would be very much appreciated. Especially the scrolling thing.

About 4-6 weeks ago Chase started throwing an error message when I tried to log in. Some other banks, credit agencies, brokerage houses also same thing. The work with Chrome and Edge.

Can Mozilla get past this or do I give up and use a predatory browser?

As much as I hate ads on YouTube I don't want Firefox to block the ads because if they find out you are blocking ads they will block you from Google and YouTube. I have Google pages and other things on their sites that have been there for years. Plus, I feel like I'm stealing a service by not lets the ads run that pays their bills and the content creators on YouTube. Please tell me where in Firefox I can turn the ads back on.

I have used Mozilla products since Netscape Navigator came out in 1995 I think it was. I went to a local internet provider and brought home a 3.5in Diskette and it loaded Netscape Navigator with my info all filled in for email, Usenet, Webpage publishing and a few Bookmarks to get started. I still use SeaMonkey for my email because it still has email addresses from the 1990's. I have Thunderbird for email on my phone. Anyway, thank you for all your work over the years.
