For some time now, when opening Firefox, I do not find the tabs I opened in the previous session. I've checked that the "Open previous windows and tabs" box is checked, but it didn't help. I uninstalled Firefox and reinstalled it from a fresh .EXE file, but that didn't work either. I've searched for resources on the subject but haven't found a solution to my problem. I should mention that I'm not a computer expert and I'm not exactly young any more.

Can anyone help me?

Thanks in advance.

Hi,

My Firefox had auto updated to the newer version with AI built-in and auto-enabled, which meant the browser would crash EVERY. SINGLE. TIME. I would launch it.

For perspective, I am running an old Lenovo Thinkcentre mini PC with an Intel i5 6th gen and 16gb of ram; its got Windows 11 installed, and always running out of memory with the simple things like browsing and word processing. This is NOT a PC or use-case that needs or warrants AI.

So, I uninstalled Firefox (149) and installed the latest version WITHOUT AI built-in (147).

I then synced my profile, and things ran fine. An hour passed, and then i kept getting an error, saying my profile was created with whatever and I need to create a new profile.

So, I created a new profile and synced, again, and I got the error, AGAIN...

I'm about to boycott Firefox on all the devices I control, and opt for an older version of Opera or something more obscure, so that I don't have to deal with this nonsense.

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

Hallo,

ich habe regelmäßig das Problem, dass Firefox quasi meinen gesamten Rechner ausser gefecht setzt indem nahezu die gesamte CPU Leistung und der Arbeitsspeicher in Beschlag genommen werden. Ich surfe in der Regel mit sehr vielen Tabs. Ab ca. 100-150 Tabs benötigt Firefox bei mir zwischenzeitlich 10 GB Arbeitsspeicher und mehr und benutzt die CPU zu 80-90% sodass der Rechner teilweise kurzzeitig nicht mehr reagiert und einfriert. Besonders, wenn ich 100 Tabs und mehr auf einmal als Lesezeichen speichere (Tabs auch nur schließen, da der CPU Lüfter schon dauerhaft auf 100% läuft), friert der Rechner danach erstmal für 3-4 Minuten ein. Ich verstehe nicht, was Firefox die ganze Zeit im Hintergrund anstellt, während z.B. 250 Tabs geöffnet sind. Tabs vorzuladen macht bei der Anzahl keinen Sinn und die Wahrscheinlichkeit, dass man richtig voraussehen könnte, welchen Tab ich als nächste wieder aufrufe und dieser dann schon vorgeladen ist, ist eher gering. Gibt es Möglichkeiten z.B.: - den zur Zeit verwendeten Arbeitsspeicher sofort zu leeren, ohne einen Tab zu verlieren oder dass Firefox geschlossen wird? - dass es dann längert dauert, wenn ich einen Tab anklicke, da dieser ja nicht mehr im Cache ist, und erst wieder in den Arbeitsspeicher geladen werden muss, ist selbstverständlich und vollkommen in Ordnung. - Kann man irgendwo einstellen, wie viele Tabs z.B. im Hintergrund aktiv sein dürfen? - Kann man den zu verwendeten Arbeitsspeicher begrenzen? - und was passiert, wenn die Grenze erreicht wird? - Kann man irgendwo an den Zeiten oder ähnlichem schrauben, wonach Tabs automatisch entladen werden? Chrome friert Tabs scheinbar automatisch ein, zu mindest ist die performance dort besser.

Es bringt ja nichts, wenn alles versuche wird im RAM vorzuhalten, damit es sofort da ist, wenn der ganze Rechner damit in die Knie gezwungen wird und am Ende das gesamte System nicht mehr zu bedienen ist. Vor einigen Jahren ist Firefox bei zu vielen Tabs oft abgestürzt, dann hat sich schon gebessert.

Es fehlt mir an Einstellungen zur Anpassung, was Firefox im Hintergrund vorhalt und was Tabs machen dürfen, wenn sie nicht aktiv bedient bzw. benutzt werden. Manuelles "entladen" kommt für mich nicht in Frage, da es zu aufwändig ist, bei extremen "Multitabbing".

Ich bin seit meiner Kindeheit begeisterter Mozilla Fan (seit Gründung von Mozilla) und verteidige und empfehle Firefox wo ich nur kann. Aber dieses Performanceproblem besteht schon sehr lange, ist zwar über die letzten Jahre besser geworden, dennoch zwingt es mich schon fast, nach einer Alternative zu suchen.

Generell fehlen viele Funktionen für Extrem-Multi-Tab-Benutzer wie z.B., dass man Tabs in der Leiste markieren oder sortieren kann. Ein großer Segen wäre eine Funktion, dass Tabs, die man bereits als Lesezeichen gespeichert hat oder doppelt geöffnete Tab, direkt zu erkennen sind, ohne dass man den Tab aufruft. Aber andere Thema. Ich benutze auch keine vertikale Tableiste, nur die horizontale klassische Leiste oben am Bildschirmrand.

Ich wäre sehr Dankbar über Tips zur Lösung des Problem mit dem Arbeitsspeicher.

Grüße

when Google share links are sent to me, they won't open in Firefox. I have to copy and paste the entire uRL and open Chrome in order to view them on my android device. Pixel 9

After clicking the "Set up free VPN now" button, the explanation page with the individual steps appeared, but I couldn't complete the process because the setup prompt was not visible in the browser.

mobile thunderbird email account desks we inform that my mozilla thunderbird email account setup do it processing ok, yes /no rights activists my with us share, please

My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

To be honest. Firefox is starting to be a big pain to use. I'm starting to see more and more of this screen where it say's "Be careful. Something doesn't look right" Even when i go to the advance and say proceed. Nothing happens and i'm getting no where. I know many of the sites don't have anything to do with asking for credit card, Scam or even having popup's. I test the sites in other browsers and there work without any issues. But Firefox is starting to lock me out of many sites due to this. How can i make this stop. As i used Firefox for many years.

The sample that is in the screenshot is a Anime data base that i have also used for years. But today shows this. But was working fine yesteday. What is going on and how can i fix it. So i can start using the browser that i love on the sites i want to.

I'm getting "Thunderbird can't connect to the server" message, so I can't download messages. However, a message or two will finally download 1-2 hours later.

Same problem on 2 laptops, both running Windows 11. But I know my emails are coming in as I can view them via Spectrum webmail. So the problem isn't the Spectrum servers.

I've logged out and back into Thunderbird, and have re-booted my laptops. No luck. What to do?

Also, is there a place to report problems directly to Thunderbird?

Thanks for any help.

Cannot send or receive email all of sudden in Thunderbird. When I the click the messages icon, nothing happens, and I get "Could not connect to server mail.twc.com; the connection was refused". When trying to send a m,message I get "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." No settings were changed and everything was fine when I put the computer to sleep. This happens on both a Win 7 and 11 machine Email is a Time Warner (now Spectrum) Road Runner account (twc.com). Spent an hour with Spectrum, and they say this is a third party (Thunderbird) issue. A friend has the same setup, and is having the same problems that started at the same time. Win 11 version 150.02 Win 7 115.18.0 (latest available for win 7)

Appreciate any help....

Just updated my Firefox. I had a huge tab group saved, and tons of bookmarks. I've been using firefox for months, I didn't have an account signed in on the browser though. I updated it and it had to restart, and everything was gone when it reopened. I even clicked that it should reopen tabs after restarting, but it just opened to tell me to make a profile. It told me that they just introduced profiles, and it put me on profile 1, which looked brand new. No browsing history whatsoever, no bookmarks, my background that I set is gone, and I cannot find anythign at all. I had over 50 bookmarks, inclyding very imprtant links for a final paper, and I'm genuinely so upset. Multiple of those bookmarks were things for me to go back to read/watch later and I will literally not be able to find them. If anyone has any tips at all, I'd love them. I am so seriously upset right now and I'm just hoping its possible for that to come back.

My Mozilla account has been disconnected. When I try to sign in, I enter my email and password, and am then prompted to enter a confirmation code that reportedly was emailed to me. The problem is that no such email arrives. Without that access code, I cannot log in, and syncing does not work. This is not a problem with my spam filter, because that filter is turned off, and I have no difficulty with receiving emails from other senders. How can I either get that access code sent to me, or get logged in without it?
