Today my BT Yahoo webmail login fails to authenticate my credentials with the message "Please check you entered your username and password correctly and try again." It worked fine yesterday. I tried it on Edge and Chrome and it works fine on both. What has changed since yesterday?

Hi guys, I suddenly can't access email on Firefox this morning when it still works fine on Edge. email provider said they'd had same problem with some other Firefox users this morning. Any ideas please? Problem persists across several PCs and is still there after 4h. Thanks, Rob.

Witam, zawsze na pasku zakladek, jak pierwsza opcje mialem "Często odwiedzane" czy cos w tym stylu, po angielsku "most visited", pokazywalo mi ktore witryny najczesciej odwiedzam.... mam teraz firefoxa 76.0.1 i znikla mi ta opcja, jak ja przywrocic?

Been using Firefox for a while now but there seems to be an increasing number of sites that won't function properly with this browser. radiotimes.com and curzonhomecinema.com are an example of this. These sites work perfectly well if I open them with Microsoft Edge.

For years I use Mozilla products Firefox and Thunderbird with great satisfaction. Recently I installed both on a new windows 10 laptop. When being on any given website I click on an e-mail adress, it does not open in Thunderbird. Instead I obtain a popup window with several options, but not Thunderbird. How do I solve this ? Thank you.

This site is not opening in FF, will open in Edge. Disabled Ghostery, tracking protection in FF still not working. Added to exceptions list in Privacy Badger, no joy. Tried reset of browser with Ctrl+F5, and also enabled popups for this domain.

I apologize if this is stupid question but this is my first use of the support forum.

I posted a question yesterday about the interaction with HTML forms and had a dialogue with help.

How do I find that dialogue today? I mainly want to post the problem has gone away as mysteriously as it appeared. It lasted for 2 days, and was isolated to something in an extension or such as things worked correctly in safe mode.

Thank you.

To make a long story short, I created This Firefox account to get support creating another Firefox account... After trying to set up "sync" on my laptop (where I normally browse using Firefox – I am writing this from the desktop that I wanted to get synced) I got an error message with the heading: "Cannot create account", followed by the text: "You must meet certain age requirements to create a Firefox Account." This is strange, since I am 19 years old (I suspect that I entered the wrong nubmer). I really want to get my laptop and its profiles synced, since much work has been put into browser-personalization. How do I fix this problem?

Best whishes, Renen

a website () states "Academia.edu no longer supports Internet Explorer." please upgrade your brower. Yet this does not help: i can nolonger enter into of said website my account. What ever I try; the website repeats said message in a plain document front and face.

I am unable to login to either of my bt email with Firefox on my Windows 10 pc. I get a username or password is incorrect. True Key is filling in the form so I know they are correct. Tried manually entering details but same problem. Thunderbird works ok. Can login ok using Microsoft browser. Can login with Firefox ok on my laptop. So it is a problem with Thunderbird on this pc. Deleted history and cache but still failing. Not come across any problems on other sites. Firefox 76.0.1 64-bit. Anybody any ideas?

With latest update 76.0.1 i can no longer watch 2k and above youtube videos. Sound will work, but video is frozen. CPU usage goes to 100% then randomly video would unfreeze and start working at that moment cpu usage drops down to 20% only to freeze video second later again with high cpu usage. Whats going on? win10x64 intel 2500k nvidia 1050 16gb ddr3 ssd Chrome is working fine. If i revert firefox to older versions video works normally.

Is there a fix in Firefox for this

when using google docs in Mozilla Firefox, my default broser, the right click paste does not work - Firefox requires Ctl. V instead

Thanks Mark

Whenever I open a new window, it starts in a certain standard size (at least in Firefox 77). In earlier versions it would always open "maximised". So for me this behaviour changed (not sure exactly in which version it changed). Since I use my browser almost always with maximised windows, I have to maximise manually all the time now, and that is inconvenient. How can I get the old behaviour back? Preferably I would be able to establish a size I like (maximised, or otherwise as big a size as I set), and then save those settings for the future. Alternatively, I would also be happy if Firefox remembers the size of the window I closed latest. Is there any way to accomplish this?
