There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

Even though my settings in Firefox are set to restore open tabs when restarting, and Firefox is my default browser, I was unable to restore my open tabs when my Firefox browser just closed on me. I went up to the menu > History > Recently closed tabs > Reopen all tabs and nothing happened. Is there anything else I can do? Thanks for your help!

This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

https://appointment.questdiagnostics.com/schedule-appointment/as-personal-information

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

I get an error message when I try to update (see screen shot below). Thunderbird is on a Windows 11 Pro PC with the latest Windows updates. This has been happening for a couple of weeks now.

Thanks in advance for your assistance.

Thunderbird will not start because the first visible startup action is the popup window: "Please enter your Primary Password". Unable to create a password for the initial,first time re-start of Window if on old machine, option was to avoid this. How to fix? ...so I can set and set and use it.

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

Folks:

I am running 64-bit Windows 10 Pro ,version 1511. I had been running Thunderbird 52.9.1 without any problems whatsoever. A few days ago, Thunderbird upgraded to 60.3.1. Thunderbird became unstable and unusable immediately upon start. Taskbar and Process Explorer showed that the program was running, but the window would not stay open or even stay stable.

I was able to use System Restore to revert to the previous version of Thunderbird, and although the calendar functionality is gone, it seems to work fine.

Any help you can provide would be greatly appreciated.

Thanks!

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

I now have the problem that I am on a large payment page and switch back and forth between FF and another app (to copy payment-relevant data). Unfortunately, FF does a page refresh every time it is brought back to the foreground from the background. And all the data already entered is lost! This is a fairly well-known problem with FF on Android! Chromium manages this better and leaves the memory management to Android. Why can't FF do that? Why can't I switch off this feature? I can't edit any relevant websites with the FF. I have to use Chrome for that! Hooray!

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

Hello; Windows 10 & current version of Thunderbird. I am trying to add Messages Filters to filter out spam (getting more and more of that!) but the "OK" button on the add message filter is below the bottom of the screen. The window cannot be raised or resized to make the button visible. Photo below. Moving window does not allow me to raise window above top of screen. Keyboard (Alt-Enter) / Move will not work. Changed windows screen size just makes window larger but button still below bottom of screen.

Non-functional work around. Highlight Message name. Press Shift-Tab TWICE. Press ENTER. UGLY!

Thank you for your time and attention.

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

I currently receive all messages sent to me including those from Comcast but I can't send messages to any email address. When I logon i get the message: Enter Credentials for my email address on imap,comcast.net. I read the document: Switch from POP to IMAP account > Create the IMAP account. I never saw the window shown on page 3 of the document. The other day I got a message that the IMAP account was already created. I then edited the my SMTP account.

Hello

What are the restricted sites in the Firefox extension details? What are the sites restricted by Mozilla, as referred to on the page https://support.mozilla.org/pl/kb/dlaczego-niektore-dodatki-nie-sa-dozwolne-na-stronach-ograniczonych-przez-mozille?as=u&utm_source=inproduct#firefox:win10:fx135 ?
