I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Firefox iOS updated this morning to 143.1 In private browsing it’s in dark mode automatically and won’t change even if changing to light in the settings.

Any help? Steve

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?

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

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.

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.

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?

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.

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!

Had this problem suddenly crop up since the update of one of my accounts not sending mail due to timeouts. I've not changed any passwords or settings since I had it working last. The message is the "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) [my workplace's SMTP server] timed out. Try again." one, and it's preventing me from sending any emails.

Specifics:

• It's one account (my work one: work runs an Outlook/Microsoft mail server).
• My personal account (gmail) sends fine. Both accounts recieve email fine too, so this is just one direction on one account.

Things I've tried:

• Switching my Firewall off makes no difference, so it's not a firewall problem
• It's not that the emails I'm trying to send are too large, one word test emails also don't send
• Extending the timeout time by 3x doesn't help

I also opened a second computer not yet running the latest version - the account worked fine. Then applied the upgrade and that broke things in exactly the same way as described above. So I'm pretty sure this is an issue caused by the upgrade in some way. Not sure if other people with Outlook servers are having the same problem or if there's any workaround available but would appreciate advice.

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!

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.

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?

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!

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 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
