I dread the days where FF has an updated version of something for me to install.. because this issue ALWAYS rears its ugly head.

I've been ignoring the updates since Feb and for very good reason because this time (138.01 or whatever) I'm unable to bypass these security certificate expired error codes that say:

"If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." I literally was able to access all these sites without issue until I downloaded your must have update. How is this fixed???

Should I just uninstall FF and go back to Brave? I'm so tired of dealing with this as a normal day to day, no coding/tech background, etc. internet user.

So Thunderbird auto updated last Tuesday and although I was then sending emails as normal with no error codes and them still showing as sent - they weren't received. I spoke to Fasthost who said my messages were being registered as spam by my own server so deleted before they could be received to my recipients.

Had my DNS settings changed as recommended, I don't have any firewall activated and can send emails just fine through outlook online but not through thunderbird. Fasthost have checked all of the Thunderbird settings for me and they're all correct?

I've changed my passwords and logged back in.

I run the business on this email account and am now struggling so much because of it - please help!

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

From of a like question (why now user ids only shown now, then pw field), GeraldR on 2/13.25 @ 17:49 presented this: Walmart.com's user-id field explicitly disables autocomplete:

<input autocomplete="off" id="react-aria-:R15at5j6:" type="text" name="Phone number or email" aria-label="Phone number or email" enterkeyhint="go" autofocus="" class="w_9iFI" value=""> _____________________________________________________________________________________________________________ If I copy the URL for 'that' sign-in page, place into EDGE, going to the input field, I get a pop-up of saved data. Is there a config setting that needs to be 'flipped' so the site is presented with my saved user ids & passwords again? I have tired of just assuming this is the 'new, how it is'. No replies of just using EDGE, please.

I am not 100%, but a 'REFRESH' has been done, just not sure if it fell in the time of the above no longer functioning as before. I have not tired in SAFE MODE. ENHANCE TRACKING PROCTION is now off ('on' did not work either; all scripts accepted in 'NoScript'; uBlock & Privacy Badger are 'off' for that sign-in page.

Autofill keeps bringing up an old email address as a choice when logging onto website accounts. When I accessed 'Autofill' under 'Settings,' there was no choice for email addresses (see circled area on photo). Is this not a feature, or am I in the wrong place? If this isn't a feature, I would like to suggest this addition.

Hello.

Everytime I open a new Firefox window, I get this warning from my antivirus:

Suspicious connection blocked 8 minutes ago

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to sync.contextualadv.com. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Usually, when I see this happen, the company fixes the issue within a day or two, but this has been occurring since at least 4/9/2025. This warning occurs regardless of whether my browser is logged into it's Mozilla account or not.

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <script> let instance = undefined; async function loadWasm() { try { const response = await fetch('./sum.wasm'); const buffer = await response.arrayBuffer(); const sharedBuffer = new SharedArrayBuffer(buffer.byteLength); const tmpView = new Uint8Array(sharedBuffer); tmpView.set(new Uint8Array(buffer)); const module = await WebAssembly.compile(sharedBuffer); instance = await WebAssembly.instantiate(module); } catch (error) { alert(`failed to compile in wasm: ${error.message}`); } } loadWasm(); function testWasm() { if (instance) alert(`sum 1 + 2 = ${instance.exports.add(1, 2)}`); else alert('invalid instance, failed to compile'); } </script> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

Greetings,

Last week I started getting blocked from sites I normally access. Several are related to hunting. This is the message that comes up:

logo This site is blocked due to content filtering.

Site blocked. buckmasters.com is not allowed on this network as it may go against Christian values.

This site was blocked due to the following categories: Weapons

It says it is from Cisco Umbrella, which I don't know anything about. How can I remove it?

Thank you, Andrew Howell

I have been using Thunderbird for over 15 years without any problem. Two email addreses are managed by Thunderbird. My emails are classified in about 200 folders. I use Thunderbird on 3 computers and all my messages and folders are synchronized via Dropbox. Starting about 6 months ago, messages have started disappearing. Some new folders have started getting duplicated. For example, FolderXX was duplicated as FolderXX-1 with only recent meassages in FolderXX-1. Most recently, some folders have been emptied of all their messages with only the last message remaining. This message loss is a real problem. Could it be due to a recent problem with Thunderbird, or a problem with Dropbox, or an incompatibility between Thunderbird and Dropbox ? Thanks for any help Florent Domine

Opening a PDF from an attachment in TB (version 138.0, Build ID 20250423163813), scrolling to any page, and choosing to print "current page" always points to first page. I tried this from two totally different machines and accounts, one Win 10, another Win 11.
