Hi. I have an email purporting to be from Microsoft telling me that I will have access problems with Thunderbird from September onwards. Something to do with authentification. Assuming it is genuine (is it?) I have no idea what to do. It gives 'instructions' which are incomprehensible to me. I dont even know why this link is to Mozilla rather than thunderbird. I don't want to loose Thunderbird's calendar or stored files let alone the ease of access I currently enjoy. I need someone kind and patient to tell this novice how to move forward in a pedantic, non-terminology way who is happy to assume I know nothing! Please help! Brian

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

Hi. My hard drive crashed. I have a new pc and the old drive is readable in a drive enclosure hooked up to new PC via usb. I have done the typical search for the appdata profile file, but I am not sure what I have here. I have attached a screenshot of the old drive and a global search on "Thunderbird". I am not sure where the profile file is residing. Any advice would be welcome. Thanks.

bold text4 or 5 years ago i simply synced TB and Firefox straight to my laptop from my desktop. Today it does not seem to work that way. Why has it gotten more complicated? I have all of my emails, address's and etc.saved profile and cannot seem to replace it. I tried the thunderbird.exe -p and it gets confusing there. Apparently it does not give one the option to replace profile like mine, but one can create one. I tried creating by entering my old Profile and it did not work. It says to use the Browse button which should bring you to the actual spot to add your profile. I do not see a 'Browser" button, but do see 2 separate folders buttons, but i do not know which to choose, if any. I have donated in the past when things were working smoothly, but discourged to add to it now with all these upgrade mess's. Like they say, "if it ain't broken, leave it alone..." s amd

I created a signature years ago. With the last Thunderbird update, the signature font (and image) shrunk in size. I would like the signature to match the font size of the message text, like it used to. I can't find any information about that, or any explanation as to why it shrunk.

Hello. I suspect there was a cyber attack on April 1 2024. All of a sudden,having problems crashing with more than 1 browser. My Brave browser would open,and then crash with multiple tabs that had been saved. My Mozilla history was cleared,and I want it back because I need to find all sites I have visited from time to time for logins etc,but they are now gone.I have tried importing all of my Brave history,login forms to Firefox,but not sure where to located them or where they would be stored.

Right now i am focused on getting a Firefox profile from before April 1

I have never had to deal with this sort of thing before so i am saying that i may be somewhat noobish on this.I just want some expert instruction on what to do here,and how to do it.I,m not 100 percent sure if i can do it correctly on my own by googling this myself,then attempting it.Brave continues to open then crash right after,so I dont know whats going on there with the userdata folder in the appdata folders with regard to Brave. Everytime i try to install an older version of Brave,it says i already have a curent version of it,and i dont want to uninstall brave then reinstall it again,or not sure if i should do this. ThankYou.

Hello,

Thunderbird keeps crashing. That is about all that I can tell you. It started this morning (/when I got to work I fist noticed it). I have not used any add ons. I have been submitting crash reports. Crash data avaiable on request. I uninstalled and re installed, same result; crashes immediately on start up.

Please assist.

Thank you

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

For about the past week I've been having trouble with Gmail and Google Search in my Firefox browser. Typically, I open a Firefox window with multiple tabs and leave the window open all day. I always have Gmail and Google Calendar open in tabs. What happens is that the Gmail tab will at some point give me a message that it cannot connect and has timed out and is trying to reload, but it never reloads, it just stalls. Then I try to open a Google search bookmark to search and the tab remains blank. This happens multiple times throughout the day. Meanwhile I can open Gmail or any Google page in Chrome, which I don't like using.

Sometimes I can close out the Gmail tab that won't load and try to open Gmail in a new tab, but that stalls out too. The only way I can open Gmail again is to close out the Firefox window completely and then relaunch it, then it can open Gmail or Google... until it breaks again.

This never used to happen. I'm using the latest versions of Windows 10 and Firefox on my desktop PC. Nothing else has changed.

Please help me fix this, it's very annoying.

I've been a Thunderbird user for years. I have no idea what they changed recently, but it's incredibly, incredibly SLOW, almost to the point of unusability. Even something as simple as deleting emails.

I usually do these in chunks -- select multiples and delete. We're not talking about hundreds of emails at at time here, just maybe 5-15. Select them all, hit delete, and it should take just a couple of seconds to delete the messages. It did, in the past. But lately, it's taking so long that I could leave and make a sandwich, and when I come back, maybe it will be done. Maybe it will still be working, though, or maybe it will have locked up because it was taking so long.

It's pretty difficult to get work done at this rate.

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

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.

Been using Thunderbird for 20 years but never had this issue. I might have pressed some keyboard shortcut wrongly?

My inbox does not show any message, even though there are two of them (and more incoming, there was one when the issue started). As far as I can see, I have no filters of any kind activated.

Any idea how to see the invisible messages again?

Thanks!

Just received an email stating that after Sept 1, Microsoft will no longer support the use of third-party email apps without use of 'Microsoft’s modern authentication methods'.

What does this mean for Thunderbird?

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?
