So every time the browser crashed or a blackout happens and it forced closed (sometimes the browser is closed normally and it still happens) the next time i start the browser it would show the restore session page. Pressing the restore session would just restore the open tabs and not the tab groups. Because of this i would need to go to the file manager, copy the previous.json and change it to replace the sessionstore. it's kinda annoying. is this problem just me or is this a known issue? also how to fix.

When I move down the screen the tab bar (where it shows what tabs are open at the top of the screen) disappears and it reappears when I move back up to where it should be. I must have switched it on accidentally and can't turn it off. One thing I read said to go to More tools > Customise toolbar > Return to default (this might have been for a different problem but I tried it anyway). When I did that it seemed to work temporarily but then the tab bar disappeared again.

Thanks in advance! :)

Title says it all, "auto resize pictures using CTRL - + does not work". Generally speaking, the size of pictures simply WILL NOT reduce in size to view its entirety. Even when the scroll-bars are used the picture is still to wide. I have searched and asked for any setting in about_config, NOTHING! I truly expected something. The ONLY STUPID WAY to view said oversize picture is Download it then view. Isn't that a HACKERS DREAM??? YES I HAVE tried looking in SETTINGS and searched for months, found nothing that actually works. So now I have to use that 4-LETTER word... HELP!

Delay moving messages to and from 4 certain mailboxes (win10, v152)

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.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Several days ago a trio of "warnings" all labeled Mozilla Firefox popped up on my monitor. They included "Critical Error! Remove viruses now", "Warning! Virus Detected Clean Your Device" (with the choice of Renew Now {? renew what?} or Update Windows), "Warning! Your system is damaged by virus attack via d9BvqdcBn2sc73dc4btg.korvapod.co.in Remove the virus now", "Trojan Detected! (choose Remove virus now or Quick Scan), and variations on all of the above. I ran a malware scan from another provider and their advice was that this was an attempted hack so under no circumstances should I click on anything. They definitely said it wasn't from Mozilla Firefox. BUT they also couldn't find any traces anywhere in my computer. So for the past 5 days, I've been functioning with a partial screen, maybe 3/5 of full screen, because those darned "warnings" cannot be physically moved off the screen. How can I get rid of this mess? Thanks.

I wish the subject line in an email would be editable ala Office Outlook. I make frequent online orders and the acknowledgment emails often simply have a subject line such as, 'Thanks for your Order' 'Order delivered' 'We got your Order'. That tells me very little. If I could add something like, 'Best Buy - backup ups battery', 'eBay - head phones', 'Walmart - house wares' that would make life much simpler. --Don

Hallo, ich habe gesehen dass ältere Mails in meinem Posteingang zwar noch von der Überschrift vorhanden waren aber wenn ich drauf klickte waren die Mail leer, ohne Inhalt. Ich habe dann den Rechtsklick gemacht und auf reparieren gedrückt - jetzt sind diese Mails ganz aus dem Posteingang verschwunden!

Ich hab nun im Internet ein bisschen gelesen, da wird davon gesprochen die msf (?) datei zu suchen und diese zu löschen. Und beim neuen öffnen von Thundermail würden dann die Mails alle geladen werden...Ehrlich, da traue ich mich nicht so wirklich dran, löschen hört sich immer so "böse" an...

Zur Verdeutlichung: ich habe den reinen Posteingangsordner und in diesem Posteingangsordner liegen viele Unterordner als seperate Ordner. Und eben diese separten Ordner die als Unterordner im Posteingangsordern sind dürfen NICHT gelöscht werden!

Also Hände davon lassen oder kann da nichts passieren?

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek
