I have used Mozilla Firefox as my default browser, for years. Recently, I used a program to clean (what it said was) junk files from my computer. Unfortunately, I did not make a rescue point. After removal of the files, several of my programs, including Firefox, has no longer worked as it once did. I was always able to go into settings to select my browser, my search engine, my home page, etc. That is no longer possible. I was wondering if I should uninstall Firefox and reinstall - or is their another easier way to repair my problem?

Any help I can get is much appreciated.

Thunderbird has been working OK. Now, despite PC restarts and so on I get the message "mail couldn't be sent, time out error for SMTP server. I have tried changing the SMTP settings from port 465 to port 587 but no difference. If I log in to my email provider (vodafon/uniymail) I can send mails no problem. The problem is with thunderbird not sending smtp. Tried turning firewall and antivirus off, no help. Internet connection is glassfibre, internet works OK.

Not sure how it happened but I've suddenly lost access to my Google calendar. On the bar on the left side of my calendar display screen there is a list of two calendars, Home and my email address, which I think is a Google calendar. Even though I check "Show all calendars" it does not show my email address calendar. And if I click on only to show my email address calendar it shows nothing at all. On my Pixel cell phone I can still see both the Home calendar and the Google calendar, so I guessing Thunderbird has just lost the link, although it shows a googleapi address when I click on properties. When I accept a Zoom calendar listing it has always and still shows up on the Home calendar. This seems most mysterious. Anyone have an idea of what I should do? Is there anyway I can rebuild the link to the Google calendar?

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

Since the latest update a Yahoo Mail sign-in keeps popping up...sometimes two different versions. It's driving me nuts. Should I uninstall/reinstall Thunderbird. It's so frequent for no apparent reason that I may have to give up Thunderbird and many, many years of use...and donations. thx, deanna

I can't seem to locate how to activate the microphone in the AI sidebar. I have Gemini selected, and when I hit the microphone to dictate I get the following message.. Unable to access the microphone. Please check settings.

I looked through Firefox settings and my laptop's but I don't see where it is turned off or asking for activation.'

At one time before several updates ago, all messages in my inbox were separate. After a previous update, reply or messages with the same header started be be nested, each one showing only the sender and the subject, which is now the same. I am forced to read through them all to find the one I want. Deleting any in the change can be hazardous.

How to go back the old way of message display?

When I send an email from my account dezandcathy@optusnet.com.au, I receive a message "Your message was sent but a copy was not placed in your sent folder (sent mail) due to network or file access errors. You can retry or save the message locally to local folders/sent mail-dezandcathy@optusnet.com.au" This problem has only occurred within the past week. For some of my sent emails, I have retried sending the message and it has appeared in my sent email folder, but not for all the emails I have retried. Checking with the recipients, they confirm receipt of my emails even though they are not shown in my sent email file. Can you suggest a solution? Thank you Derek Maule

I have an Intel I5 PC that runs MS Win XP. The reason that I'm still running that ancient OS is because of whats inside it. I have two old boards in it that I still use and quit honestly can't afford several thousand dollars to replace them. And the new machine to go with them.

I need to get online to download the few pieces of software I need That are still out there. But like most sites they examine your machine to see what versions you need and it's a download and install package. So I can't use a different PC.

My question is: Is there a version of Firefox I can download that will work on XP, and not be ignored like is done to IE 8. And that I can then transfer to the XP (service pack 3) box for installation?

Preamble:

1. There are 34 email Accounts listed in left column.
2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

When setup the SMTP server, under the security and Authenication; only "User Name" is provided, but there is no "Password" field provided for input, please resolve this problem.

Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

I'm on version 148.0, dragging tabs stopped working, not on horizontal and not on vertical tabs I've tried to create a help ticket for it but apparently the help form just does nothing and doesn't send when I click submit Anyone else experience any of these issues? And how can you contact Mozilla even? Edit - fixed after windows restart
