This issue shows up randomly, affecting a random number of messages. Issue is that one message will take over other messages following. Message notification will look normal in the inbox, but click on the message following X message, and the X message is what will appear. The subject line at the very top of the page will be from Y, but the rest of the information following will be from X. Two, three or more messages may be affected. Deleting X will make no difference. This time, four messages were affected.

Hello, My GMX MailCheck Email extension/ addon is being blocked by blacking out the screen. This has only occured in the last couple of days; before it worked perfectly. I have been using Mozilla Firefox Browser for about 20 years.

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!

I use gmail for both personal and work (business) account. I have both accounts logged in and open on Chrome and Firefox. On the Firefox browser every 5 to 10 minutes the web page shows error 001, and the page wont reload. Only fix is to restart Firefox. However, at the same time the same accounts are not having problems via the Chrome browser.

I have no add-ons or extensions enabled on the Firefox browser. I have already done a Firefox reset, that did not fix the problem. I have done a uninstall and re-install of Firefox, that also did not fix the problem.

Getting error message on mozilla when try to log into godaddy, same message does not occur on microsoft edge, went through all possible godaddy glitches, they say it isn't one of theirs, rather the browser

Steps to reproduce:

Nothing! I walk away from Mac at night. When I come back in the morning, all of my normal apps are available and running fine (including Firefox). However, Thunderbird is unresponsive. Clicks aren't recognize. However, I can quit it and relaunch with it normally operational.

Actual results:

Thunderbird was unresponsive.

Expected results:

This shouldn't happen at all.

Hey. I have this weird bug on Firefox ( left window, right window is librefox ).

The bug is the " select text" thing. As you can see, librefox don't have this bug, edge same too. Already tried to reinstall, downgrade, update, delete all files related to firefox, deleted pref.js.I think I already had this on youtube for exemple, but not quite sure. I tried different mouses, but it's purely firefox.

I have two email accounts. On the first one I cannot send or receive emails. I get message "login in to server imap.telstra.com with username *******@bigpond.net.au failed."

On the second I am receiving and sending emails but it is not saving my sent emails.

Any suggestions?

While I'm doing my emails, I get a yellow error message: this page is slowing down your browser. To speed it up, close this page. That's my hotmail inbox. Happens often. If I close the hotmail then reopen it it works ok for a while, then does that again. And in general it's slow. Feels like firefox and hotmail are at war with each other...

Internet explorer works!

My Thunderbird email works perfectly when the PC is connected to a network by WiFi or cable. But when I connect the PC to the internet via the 'Personal Hotspot' (shared internet) function on my iPhone, I can only receive emails, not send emails. See attached screenshots of the error message and account settings. I use Thunderbird version 91.9.0 (64-bit), and Windows 11 Home version 21H2. Windows Security for antivirus and firewall. Mail provider is domeneshop.no.

hey all, I hope you can help! Thanks in advance.

Thunderbird crashes and hangs up many times every day. I am using a macbook pro, OS Monterey, 12.3.1 and Thunderbird 91.9.0 (64-bit).

When I try and submit the crash report I get an error page on submit that reads "Bad Request (400)". Trying this short thing in case the problem is how long that is ...

Hi! Upgrading to version 100 has made Firefox completely unusable for me. Every time I open it, the "Password required" popup appears, which is normal. However, whether I enter my primary password or click "Cancel", the popup goes to the background and I cannot close it, nor click on anything in the app. In fact, I cannot even close the app except from the upper menu bar (I'm on OSX). See the attached screenshot to get an idea. Please help!!!

I just switched over to Thunderbird after seeing so many people saying it's the gold standard and I am having nothing but headaches with it so far. Hopefully it's just my computer illiteracy that's the problem. Any help would be MUCH appreciated!

The first I'm facing is that emails I open (and even respond to) keep automatically marking themselves as unread. It generally happens several seconds after I click on the message.

Another issue is that some messages I click on won't mark as read automatically, unless I click on another email, then back onto the one I want to respond to a second time, at which point it will finally mark itself as read (and occasionally go unread several seconds later).

A third issue is that when I switch from one email account to another, rather than keeping all unread emails open showing, it will switch to show all emails and it will automatically open a random unread email, which I'll then have to manually set back to unread before responding to the email I want to respond to. It also means I have to change the emails shown to all unread again, as well as having to change the date (I like to have newest emails at the top - Thunderbird insists on having them at the bottom). I already have the pin selected, so in theory it should keep settings from one account to the next, but it doesn't.

A fourth issue is that I'm using Conversations so show my replies in the thread in the inbox a la Gmail. Half of the time my replies show and half of the time they don't, so I have to manually check in the sent folder to see if they've actually been replied to.

Pleeeeease help anyone thank you!!!

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

I woke up yesterday and found Windows telling me I needed to restart my PC to install two new monthly updates: KB5013942 (Windows 10) and KB5013624 (.NET) and the related servicing stack.

[https://support.microsoft.com/en-us/t.../may-10-2022-kb5013942-os-builds-19042-1706-19043-1706-and-19044-1706-60b51119-85be-4a34-9e21-8954f6749504]

But after I did, I suddenly found that Thunderbird no longer had the ability to send e-mails -- only receive. The paper airplane icon was greyed out.

After checking some other things, I ran the usual uninstall and the ability to send e-mails was back . . . but it's gone again this morning, and the updates seem to be back. And of course Microsoft doesn't have this as a reported issue yet, either. I hope the problem can be fixed soon -- before my update pause ends.

UPDATE: To clarify the paragraph immediately above . . . this morning, the two Windows updates I'd uninstalled were back -- so, after inputting this question, I re-uninstalled them and re-booted the PC . . . but this time it didn't help. I'm STILL not able to send anything from Thunderbird. For everyone else's sake, I hope I'm the only one who has this problem. But for purposes of getting attention to the issue and getting it FIXED, I hope it's appearing on more and more screens. . . .

I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?
