Firefox is no longer remembering my logins. I had 100s out there. Started yesterday. I tried the login.json file and that did nothing. I tried db4 but I only have one copy of that file. I tried to synch with my phone, which seems to have some of the logins and it will not synch. My files are not marked to read only and I cannot find any setting that may have been tripped to prevent logins from saving. Any other ideas? Thank you.

I am trying to set up AWS Deeplens camera for a project. It is basically an Artificial Intelligent (AI) camera. At one point, when I click on live video streaming the fire-fox is showing me an error: Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

And basically here: https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect?as=u&utm_source=inproduct.

it is telling you to contact website owner for this problem. What should I do?

This is going to be difficult to explain, so I'll do my best;

Recently, Firefox has been exhibiting a problem where, upon maximizing a window, the window extends up by a few pixels more than any other maximized window. Now, normally this wouldn't be a problem as the top of the screen would cut off any extra padding. However, using a program that reserves the screen edge shows that a maximized Firefox window indeed extends past the regular window border by exactly 8 pixels.

What's more, when using Windows Snap on two separate Firefox windows, one of the windows respects the screen edge while the other does not! This leads to the window control buttons at the top right of both windows to be in different vertical positions, which is difficult to use.

No other programs I have exhibit this behavior, which is why I'm turning to Mozilla support. I don't know if the issue has to do with the browser or how Windows 10 renders the desktop, but it throws off the design of the desktop as I intend to display it.

In the provided example picture, the left window demonstrates predicted behavior where the upper border of the window is at the position I intend (40 pixels from the true screen edge), while the right window can be seen extending past the left one by exactly 8 pixels. I have tried this with extensions disabled, in safe mode, and every other way I can think of and the problem persists. No other programs exhibit this issue. This is utterly baffling to me and I hope someone might understand and be able to suggest any solutions.

Thank you!

Hi! After the update on july 2 all my opened tabs were gone, and I can't restore them. Tried folder sessionstore-backups, but no luck. Is there any chance to go back to session before the update and get my opened tabs back?

If I check my internet speed in Firefox using various speed test websites, it shows 50Mb download, and upload shows about 9Mb. In any other Browser it reports 70Mb down and 20Mb up. It has been 70 up & 20 down for some years. If I restart Firefox in safe mode, I get 70Mb / 20Mb as expected. If I remove Add-ins, it is still slow. I tried a refresh, and it's still slow. I have no extensions, themes and have turned hardware acceleration off. Changing the proxy settings doesn't help either.

Hello. I'm using a brand-new installation of Firefox 78.0.1 on a freshly installed copy of Windows 10 Pro. The only way I can get Firefox to display any notifications is by having alerts.useSystemBackend set to true. While this is set to false, notifications will not work. If I use this site to test them, it just says, 'queued for display', followed immediately by 'closed'. I've also tried creating a new profile and testing it again with no success. All sites were granted notification permissions in each case.

Thanks for any help.

If i click on a download link for PDF nothing happens. if i click right (mouse) and select "open in new tab" or i select "download as" it works. where do i have to look first?

There seems to be nothing on the page like "New Post". Like a typical online forum. Is it just archived and if so, why would they not tell us right at the top instead of forcing us to hunt futilely on the page for some clue as to how to post?

If someone wants to reset their browser they can search how to do it. Why on earth would you suggest a reset/destruction of a full working browser under the name of "refresh" ?????

One is abstracted, clicks ok, and destroys their well set up browser for no reason at all !!!

You should rename the damn "refresh" or better completely trash it!

Fingers crossed - I may have solved this problem by completely uninstalling and reinstalling Firefox. The problem: Every time I opened Firefox, the Safe Access app on my Synology RT2600ac router would send an alert to say that it had blocked a connection to vice.com. I've never visted that website, so I have no idea why Firefox would keep triggering an alert from my router. Has anyone any idea what might have cause this?

Hi, my pc is located in the Netherlands. So it acts like a dutch browser. But i want to change it so it acts like an english browser. I want to test the english language in an app.

I like the topsites feature but when I try to add an icon for most sites, it will not work - only for a few. This even occurs if I manually add an icon from a known source. A few select sites add it automatically. This seems to be a bug.

I wanted to see if anyone could help me with the css code for the hover color in the urlbar dropdown? I have tried using this code;

#urlbar-results .urlbarView-row:hover {
 background-color: #272727 !important;

but weirdly when I choose a dark color it only colors like the outside of it and the inside still stays the same (Like in the picture I have attached)

Using 78.0.1 on Windows 10, when I press F11 to get full screen in Youtube TV, it works, but it leaves a thin grey line at the very top of my screen (1280x800 resolution showing 1280/720 YTTV), and mousing over it drops down the Firefox tab and URL bars. That's "Full Screen Level 1". Using --kiosk prevents the dropdowns, but it doesn't get rid of the line.

If I play some video and mouse over the Firefox window while it's in Level 1 and not displaying any UI, a full screen icon appears in the upper right. Clicking it gets rid of the gray line and briefly shows the message, "youtube.com is now full screen." Now, mousing over the top middle of the screen displays that message instead of the Firefox UI. That's "Full Screen Level 2."

When I start Firefox, it remembers Level 1, but not Level 2, and the only way I see to get Level 2 is to click on the icon. I want Level 2 all the time for this profile, which I use on a small secondary monitor, and only for YTTV.

Any ideas?

Did something change in Firefox today? I tried to let Firefox save a password and user name for Ask LibreOffice and when I tried to log in the password failed and I had to reset it.This happened again just now. (LibreOffice again). Firefox used to mess up in this way but that was ages ago. Everything has worked beautifully until today. Thank you!

I do not get the speed I should which is 150Mbs since mid April this year I was gettin the speed before Then i changed to chrome and when I test the speed is 185 Mbs everytime. Right now I have reinstalled the fire fox and tested with both Ookla and fast.com both are giving a reading of 37.6Mbs on the fire fox and 184 on the Chrome. I do like fire fox but if the speed is not there then i do not want to use it. I am not good at this computer stuff so if there are any instruction please use simple terms, also I am too old to learn . thanks stay safe

I recently switched from chrome to firefox. Normally I receive notifications of texts/imessages and calls in the top right corner of my screen even when I am watching videos in full screen; however, after switching to firefox I have noticed that sometimes I do not receive the notifications if I am in full screen video mode. This is causing me to miss some important messages. Is there a way to ensure that notifications such as imessages display even while watching videos in full screen?

After Firefox updated to V 77, I have a problem when launching Firefox. After I boot my PC and launch Firefox my home page opens OK. However after I close Firefox and any subsequent Firefox launching - I get a blank page. When I click "home" symbol my home page opes up OK. It still happens after updating to V 78.

i Tries everything all the recommended steps including safe mode.  However, I did not try to uninstall/install Firefox.

Any suggestions? Recommendations?
