We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

v115.7.0 I have been a user and contributor for years. OS is still Win7. I have had a IMAP connection to Comcast for years, now it will not connect. I have made sure I am using the correct password. When I start thunderbird, a secondary window pops up with the error message unable to connect. WEnt thru lots of posts but no results. One interesting said to disable IPV6 security option, but the way they described the fix was to access thry the EDIT menu then Preferences, but my system does not have Preferences under Edit.

When I open the Manage Bookmarks in Firefox I have thousands (not exaggerating) of recently bookmarked items. How to I delete all of them? I think I turned that feature off via the browser.bookmarks.showRecentlyBookmarked. I changed it from True to False I have tried deleting them one by one but it seems like they recreate and I am not making any progress deleting. How do I delete all of them?

Thank you.

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

When running Thunderbird in Dark Mode, the message pane (that shows the message when you select it from your inbox) still has a white background. This makes perfect sense, because a dark background can easily mess up HTML mails.

Which I know because the compose / reply window does have a dark background, making it all but impossible to read what you're replying to if it was a HTML mail.

I would like to set the view and reply window to use the same background. Can this be achieved or is this a bug?

I have been successfully using Thunderbird for many years. In the last year or so I have been noticing that occasionally one of my sent emails gets corrupted such that the email body starts showing html text and the email subject header is changed to another email header that exists in the same folder but is unrelated to the email body. When I check the corrupted email from the Gmail web user interface, the email is not corrupted. I tried repairing the folder but to no avail.

I attach an example of a corrupted email below:

Yes Charlotte - please proceed - sorry for delay

BEFORE ANYONE ANSWERS THIS PLEASE STOP AND THINK. I have been using this browser since Netscape. I have been "managing" bookmarks for years and years but I have NEVER found a SOLUTION to managing bookmarks in a SIMPLE, USEFUL way. I have wasted hours and hours on this site looking for answers to the ongoing difficulty that EVERYONE has dealing with the BROWSER WARS imperative that bookmarks can be imported and therefore, perpetually duplicated in an infinite array of browser upgrades and OS installations over the YEARS AND YEARS. For those of us who have managed to ERR on the side of caution and always opt to live with the effects of this rather than risk LOSING the good data nested within, I implore Mozilla to THINK LONG AND HARD on developing a solution to this ONGOING PROBLEM WITH BROWSER BOOKMARKS MANAGEMENT OVERALL. Oh sure, there are hundreds of plugins that ultimately suck up the memory for partial solutions to the PROBLEM that is caused by each new installation of Firefox or other browser in which past bookmarks are imported and ultimately duplicated ad infinitum. I don't need to know all the things that are wrong with Microsoft and how developers or users create the problem, I need a SOLUTION.

Will Mozilla please be the FIRST BROWSER TO SOLVE THE DE-SHITIFICATION OF BOOKMARKS no matter how poorly mismanaged and duplicated they were in past iterations?

The more time I spend on this HELP site looking for answers, the clearer it becomes that this is a problem for DEVELOPERS to solve because none of the USERS can figure out the answers. So, BEFORE you tell me ANYTHING, SHOW ME THE MOZILLA FEATURE THAT SOLVES BOOKMARKS MANAGEMENT THOROUGHLY AND SIMPLY, because, so far, that clearly does not exist.

I've had Thunderbird for a long time, but today, when I opened it, I got the set up page. Both email accounts (earthlink and gmail) were gone, along with all the saved email folders. Running Lenovo PC, Windows 10, latest release of Thunderbird (115.7.0, 64 bit).

Also, I can't send emails through earthlink, Just get the "sending message" window (that never goes away).

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Enabling my incoming emails. This has been failing for weeks. I reset my account with thunderbird and made a donation (thinking that was the problem) but I am still not receiving incoming emails. Tried and checked all my account settings - cannot find what the problem is. Please help.

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.
