When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

Suddenly I cannot search from the search bar. It defaults to the address bar. why "fix" something that was not broken. Being forced to use the address bar is frustrating. If you go directly to the address bar, it tells you it cannot find that site.

I just heard about the new Block AI Enhancements feature on Firefox from a friend, and I was genuinely SO excited to have this option. However, I can’t figure out how to enable this setting on mobile. I’ve checked every tab in both Firefox settings and the app settings on my device, and I just updated the app this morning (02.26.26) so I’m not sure what I’m missing. Hoping that it’s not desktop only, I’d be really disappointed to have to wait on this one!

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 looked up lots questions and solution. nothings seems to work. i did all Troubleshoot and diagnose Firefox problems. cleared cache, restarted firefox, refreshed. everything I could do. nothing works.

could you tell me what else I can try?

How do I get searches (my default is Google) to STOP going to the address bar? This started out of the blue and it is making me crazy. I don't want to be asked which search to use, and I don't want it to search in the address bar. I want it in the search box. Thanks.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

I've used TB successfully for many years to access several Yahoo and Googlemail accounts. Windows 10. Recently the Yahoo accounts don't work so I've tried several times deleting and reloading them. This may be a red herring but the trouble seemd to start when I installed TB on a new Windows 11 laptop and failed to load the Yahoo accounts. I've tried following both Mozilla and Yahoo help articles but ultimately success is partial at best (i.e. incoming works, outgoing fails) This is the sequence I have followed

251128 tried this: Deleted all yahoo accounts in Thunderbird

Edited outgoing yahoo server to

 smtp.mail.yahoo.com
 Port 465
 SSL/TLS
 Authentication method OAuth2
 User name johngherrett@yahoo.com

Added yahoo account johngherrett@yahoo.com name and email address

opens yahoo! login sequence enter email and yahoo account password - FAILS

logged out of Yahoo mail open elsewhere

Accept 'Configuration found in Mozilla ISPDB'

opens yahoo! login sequence enter email and yahoo account password - FAILS

Account Hub window 'Choose your email type' pick 'Edit configuration'

Changed Incoming server settings to: POP3 pop.mail.yahoo.com Port 993 SSL/TLS Auth method OAuth2 username = email address

Test

'Outgoing server settings' 'The following settings were found by probing the given server' SMTP smtp.mail.yahoo.com Port 465 SSL/TLS OAuth2

Continue

Authentication error 'Unable to log in at server. Probably wrong configuration, username or password.'

followed guidance from Mozilla article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo Exit Thunderbird Wait a few moments for background process to complete Start Thunderbird

counted to 10+

restarted Thunderbird Yahoo account is not there Googlemail account is there - OK

'Set up another account' - email started again Name & email

opens yahoo! login sequence enter email and yahoo account password - FAILS: 'Something went wrong' - not helpful 'Go to help' in Yahoo dialog opens another page in kanji(?) close this

back in TB Account Hub window 'Choose your email type' pick 'Edit configuration'

Changed Incoming server settings to: POP3 pop.mail.yahoo.com Port 993 SSL/TLS Auth method Normal password [changed] username = email address

Test

'Outgoing server settings' 'The following settings were found by probing the given server' SMTP smtp.mail.yahoo.com Port 465 SSL/TLS Auth method Normal password [changed]

Continue

'Authentication error' as before

Go to https://help.yahoo.com/kb/sln27791.html Login to yahoo account 'Ways to securely access Yahoo Mail'

Use an app password ************

Signed out of a 'current sessions' even if not recognised. (Except 'current device' which is the login just past.

External connections-> Create app password App name : Thunderbird Generate

Copied to clipboard ********************

Returned to TB

entered password 'Continue' Spinning icon and re-opens yahoo login dialog entered normal password 'Something went wrong'

entered app password 'Something went wrong'

Despite this, after closing the yahoo dialog, TB says 'Account created successfully'!!!!

Inbox appears

Note:server settings now set somehow to IMAP / normal password

Testing outgoing: Message fails, Yahoo dialog login fails Edit outgoing server which remains OAuth2 Changed to normal password

Tried app password - failed Tried normal Yahoo password - failed

How to make Firefox my default browser on my new computer a Windows 11 computer. I’m to the point where I’ve got a pop-up window, which says sync Firefox on your phone or tablet. I am asked toOpen Firefox on my mobile device. Then Go to the menu and tap sign in. That’s where I am. Now I’m asked to tap “ready to scan” and hold my phone over the code. Unfortunately, my Firefox app does not show a ready to scan option after I get to sign in. Help!!

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

I am reopening the question from 2020 as the solution described no longer seems to apply. https://support.mozilla.org/en-US/questions/1284577

I am running Windows 11. Firefox 144.0 (64-bit)

When entering search terms into the search bar in the centre of the page, the information typed appears in the address bar, even after following the fix described in 1284577.

Treating the address bar as the search bar appears to be the default. While the user can additionally deselect the search engine in the address bar, that is an unnecessary and undesired additional step for every search (the primary reason I am using Firefox)

Is there a way to permanently set the default for what I enter into the search bar to remain in the search bar and not to be managed by the address bar? Thanks, Rich

Hello Everyone. I have an issue when trying to add a second email address to Thunderbird; I get an error 'Authentication failed. Please check the username and password...Exchange auth error' but I am able to log in to my account online using these details. It is an Outlook.com email address. Any ideas?

I'm finding that folders under my email heading are missing, until I find them completely out of alphabetical order. Then I move them to where they belong, and a day later they are somewhere else. How to correct this?

I've tried the "verify integrity" fix and got the results shown in the screenshot below. I've restarted my mac, I've shutdown and started my mac with a hard boot and the icons still show up like globes.

I'm using Win 11 and ver 140.3.1esr (64 bit)

Thunderbird works perfectly except for just one thing. Every time I write any email it freezes after about 2 minutes. If it's a short email, it gets sent. If it's longer, before I can get to the end, the program freezes, and I have to use Task Manager to stop it. No problem receiving and reading emails. This started about a month ago.

I use Bitdefender, but it still happens with that off. Windows is up to date. Any ideas why this is happening? Thanks.
