Firefox created a folder "Old Firefox data" on my desktop which is impossible to delete. I am getting an error "Access denied" even when trying to delete it as administrator. How can I delete this folder?

Hello,

I would like to obtain the complete release history of Firefox ESR Portable, including:

The exact release date of each Firefox ESR Portable version. The corresponding Firefox ESR version number (e.g., 115.x ESR, 128.x ESR, 140.x ESR, etc.). Any available information regarding delays between the release of Firefox ESR by Mozilla and the release of Firefox ESR Portable.

Could you please provide a list of all Firefox ESR Portable releases along with their release dates, or direct me to an official source where this information can be found?

Thank you for your assistance.

now have a second 'newer' PC, runnng W7 ultimate however I want TB to be 100% same on both machines. TB will not allow(even see) an 'addon' called 'confirmbeforedelete' or 'recoverdeletedmessages' which work GREAT on the XP machine. Both PCs have TB, version 52.3.0(32bit) so I'm confused as to why these addons aren't available.

Any help is appreciated.

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

How much longer will Firefox be down due to server updates on Mozilla.org? ALL of my extensions are disabled for that NLT 15 minute update that's been going on for well over an hour (I know, because my extensions are still disabled and have not yet reset themselves---Mozilla crapping them out, Mozilla returns them to my setup---to the way I had them configured. Specifically, the ones I'm missing the most right now are Tab Sidebar, Tiled Tab Groups, and whichever one(s) make bookmarks/new tabs open in a NEW tab, not clobbering a tab that is currently in use. I did that to open Duck Duck Go a minute ago, and had to re-write this whole support question because, for some reason, Duck Duck Go opened up in this ACTIVELY IN USE tab instead of a new tab. And not only that, it wiped the contents of this support chat window. Sorry, but that is totally UNSAT.

Thanks, jim74, [edited] @jdgblogs.com (which needs to change to [edited] @jstrack,net---how do I do that?), Firefox ESR 91.5.1esr on Slackware v. 15.

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

The TB Solutions only provide information for a tar "bz2" file. I downloaded a "xz" file (thunderbird-140.0.tar.xz), how do I install this?

Thanks for any help or solution.

I wish to update my current version of 128.12.0esr within my Ubuntu 24.04.2 LTS OS.

Dear friends, I recently realized that Mozilla Firefox does not support Windows 7. At the same time you want people to prefer your browser. Why did you stop supporting Windows 7. I think that window 7 is an OS used from thousands of users. I prefer to use this OS and Linux Mint. So, I do not understand your policy not to support this OS. Thank you in advance for your answer!

Don't know what to do with this:

A later version of Mozilla Firefox is required for Prime Video. To update, click the menu button (three horizontal stripes) on the web browser toolbar, click {1>Help<1}, {2>About Firefox<2}, and then click {3>Restart to update Firefox<3}.

I have lost the possibility use Finnish dictionary for spell checking after Thunderbird upgrade to version 60.3.1. How could i revert to older version and prevent automatic updates?

Ich habe WIN 10 auf meinem PC und kann nicht auf WIN11 upgraden. Hatte Thunderbird schon installiert und problemlos im Betrieb. Leider konnte ich ab ca 19.12.2025 keine Emails mehr schreiben und empfangen. Ich habe mittlerweile zig Stunden versucht das Programm wieder zum Laufen zu bringen, aber erfolglos. Ich habe es 2 mal deinstalliert, aber mittlerweile kann ich es noch nicht einmal wieder richtig installieren (habe alle Thunderbird-Dateien - auch den Cache - auf dem PC gelöscht). In GMX Mail habe ich die Berechtigung Zugriff über POP3 u. IMAP erteilt. Ich kann leider keine jpg Datei mit näherer Beschreibung hinzufügen...

My freeserve email will soon not be available so I have set up a new email address with zoho mail via their website. Now I want to add this new address to my Thunderbird email set up. I have enabled POP/SMTP in zoho. I need a new, separate, inbox for this email address on Thunderbird.
