I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

Hi everyone!

Jack here. I am a non-tech person and don't know the technicalities behind this issue. I have a Digital Media Website which loads and works quite fine when opened in other browsers but the site is loading very slowly in Mozilla and when it does load it has breakages.

Can anyone please tell me what the issue might be and how to fix it?

Thanks, Jack

I heard that the newest version of Firefox (which I have not upgraded to yet) has a feature that makes it easier to accidentally visit a website whose URL is on the clipboard. I googled to find out how to disable it, and the Featured Snippet said "go to about:config and change clipboard.autocopy to false." Sounded simple, so I did it, but subsequently found out that the article it quotes from is 10 years of age!

My first question, then, is: what does changing "clipboard.autocopy" to false do if it doesn't turn off the brand-new feature?

The second question is, how do I disable the new URL Paste Suggestion feature? Will setting "clipboard.autocopy" disable it? In particular, I want to make sure that the browser does not pre-load or pre-fetch the clipboard URL, and in fact, I wish to pop up a dialog box any time I do "paste and go." People often copy URLs from e-mails to research them before visiting them directly; jumping directly will increase the likelihood of visiting an imposter site.

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

Urgent Help Please as lost ALL EMAILS - I cannot get to post in Thunderbird: 1) I've now spent 4 hours, (from what was trying to sort a 'simple' problem on the server), as I couldn't send or receive any emails, as they think I've 6.5Gb of data on it, in spite of my deleting all my emails off it. So they allowed some extra space to temp sort it again. It's been an issue for about 3mths now. But I deleted everything just the other day having confirmed that was not deleting them off my laptop and that the previously lost emails 2 yrs ago weren't still on their server.

But now checked back on my email client Thunderbird, and I've no emails. They're all GONE bar the odd few I've put into folders (I stopped using folders years back as that lost all my emails way back then!), so I'd been keeping them all in the Inbox. Although I've a few old Inbox files with previous old old emails in so I can access them if I need to. But at least their there! But now again I've just lost everything. This is such a disaster.

Over the last 2yrs it's been going OK until today. Now it's LOST ALL MY EMAILS. I'm as per usual up to my eyes and have to travel this friday for meetings next week. The last thing I needed today was this. I've lost so much data and info in those emails it's doesn't bare thinking about. From show tickets that I need, medical info and data, to flight details to all sorts of crucial data. My ONLY saving grace is that anything I've replied to, I have a copy in the sent folder.

So Please Forgive this being in Firefox, as I can't even add it to Thunderbird help area!! I've had to reset my pw too just to sign in. Sadly right now it all feels so very upsetting I'm thinking I'll have to just have to start using another email client! If every 2 yrs I lose all my emails then this is just not acceptable. I hope you can move this to the Thunderbird threads. If you do please send me a link to it so I can try and find it.

What's so upsetting is had I saved the Inbox file when I saw the 13Gb file size, a bit eariler then, I think I could have saved them. I fear though that the remote server people deleted something, that was somehow still linked to my system and that's meant they've deleted my emails off my laptop too! Terrifying! (Perhaps that is what happened before back in '22. ???) I did look at a 'Sync' settings but not sure what they did so cancelled back out of them.

Running on Win 10 Pro 64Bit i7core 8Gb Ram Thunderbird 115.10.1 (64-bit)

Any and all help will be most gratefully received.

Sub issue to get help : 2) Error to Sumbit to Thunderbird: Sadly I've gone around and around your system saying Ask Question when nothing answers my query on the Thunderbird email questions. But when you click on Ask Question it just takes you back around the system again / Browse all Programs / re click on thunderbird/ reclick on Emails and back to list of FAQ's but nothing helps so click on Get Help and back around you go in a deja vu system.

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).

I had ab account that I deleted. however the system still tries to log into the server to see if there are any new messages (for the deleted account). The account does not exist however and it cannot access the server so it hangs waiting for a response that can never come.

How can I stop Thunderbird from doing this?

When I try to send emails, I receive this message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: [M1] Authentication required (6aecbed3-07a6-11ef-9de7-83bcbd00a978). Please verify that your email address is correct in your account settings and try again". I have checked as requested by this message, and everything appears to be in order. Can anyone help with this issue, please?

According to thunderbird, this event starts at 10:30 (second image) and runs until 11am (end time is correct.

Google calendar correctly has this event as starting at 10:00 (first image) running until 11am. This event is synced with google calendar and my outlook calendar (outlook has it as 10:00 as well).

It's not a time zone issue because the start time is off by 30 minutes and the end time is right. Any idea what's going on?

(Clearly a calendar sync that gets the times wrong isn't so useful.)

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

I have tried to restore a backup made with Mozbackup. This was a bad idea. I now have 2 profiles xxxdefault-beta and yyy.default. So I asked Tbird to install from yyy.default where i've got my recent emails and it tried to import without success. I humbly ask for some options. Can I merge 2 profiles ie copy them into one profie folder? Can I hide/rename the profiles then delete Tbird and install anew? I promise on my grandmothers skateboard I will never use Mozbackup again, + . As an aside in appdata,local,tbird,profiles,yyy.default,cache2 there's a whole bunch of alphacoded files. what do these do?
