Hi, I have a weird issue if I scroll with my mouse down a webpage I'll get these jagged horizontal lines in the middle of the screen but go away when I stop. Also, when I watch a video where a lot of moving is happening like if it's a hockey game the middle of the screen just that jagged line across in just the middle. What causes this and how do I get rid of it I don't notice on Internet Explorer browser and I've tried disabling hardware and stuff but doesn't work.

Hello! On a certain adult website, all the videos play verrrry slooooly. YouTube videos play fine. And this certain site works fine when I try it with Chrome. I recently added a bunch of adblockers like Ghostery and Adblocker plus and Badger and Decentraleyes and HTPPS Everywhere. Is the problem with one of these? What can I do to get the videos to play at full speed?

Thanks in advance!

I tried downloading wondershare dvd maker and avg popped up saying it wasnt trusted. I tried leaving the alert but it wouldnt let me so i tried pressing alt f4. Alt f4 didnt work, so i chose deletion option. But it deleted my firefox browser. Naturally i had no idea what was happening when i tried clicking the firefox shortcut and it said the file didnt exist or had been moved or deleted. I checked my uninstall option on my computer and firefox wasnt even listed. I downloaded imyfoneanyrecover app after a quick google search but for some reason when i opened the app it couldnt go in window mode and half the page is off the screen and i dont know how to switch the app to window mode. I even tried downloading firefox again and it wouldnt install. I am really confused right now and i am afraid all my history, bookmarks, etc. Are gone forever. Is it avg or was the wondershare dvd maker a malware that did this? Please someone help me!

After installing the DRM content through the browser I still cannot play any videos on Netflix or Udemy.

I have run this website (https://www.jeffersonscher.com/sumo/html5-video.html) from previous answers to check and the results are attached to the question.

I have also checked media.eme.enabled and it is set to true.

I am very much puzzled by this.

I have what I think is a specific video problem. Videos from the Washington Post get the message “This video is currently not available”. Other videos, e.g. from the New York Times do work. Washington Post videos work with Chrome and Opera.

The problem is on a new Dell Inspiron 5502 running Windows 10 and Ubuntu with dual boot. The problem only occurs under Ubuntu 20.04.1 LTS. It does not occur under Windows Firefox.

The current Firefox is 84.0.2. The problem did occur under 84.0 but I didn’t have time to pursue it.

The add-ons manager under extensions has no entries. Under plugins there is only “OpenH264 Video Codec provided by Cisco Systems”.

Under preferences, performance, hardware acceleration is not selected and the content process limit is left at 8.

Running in safe mode does not help.

I had a different video problem on a pair of the hardware visible at https://support.mozilla.org/questions/1320396?utm_campaign=questions-reply&utm_source=notification&utm_medium=email#answer-1381141 This is a different machine and a different problem.

Ever since i re-installed my windows, Firefox just won't play live streams. Neither Youtube or Twitch works. I have tried everything i have seen on internet, nothing works. I do get to see them on Chrome or Brave, but i don't like those browsers, i wan't my firefox back!!!!

Today Thunderbird has crashed on numerous occasions. it restarts and stays live for a while then crashes again. My updates are automatic and up to date. What should I do?

I can sign into medicare.uhc.com/aarp but once I am in the site anything I try to do I am signed out. I don't have this issue with Microsoft Edge so the problem seems to be Firefox. I have tried to change privacy settings but nothing seems to work

Hello, I have problem with YouTube. When I am clicking "Share" button I got screen with infinite loading. The same issue happens when I want to open menu by clicking on my avatar. On dev console I am getting a POST error: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401

I tried to: - clean Google/youtube cookies and stored cache; - clean then all cookies; - relaunch Firefox with all addons disabled; - enter via private mode with/without addons; - flush dns on dev console; - disable completely antivirus; - change DNS.

What is interesting, that problem happens only when I am logged in to my Google (YouTube) account and only on Firefox. Even on private mode it works until I do not log in to my account.

I would be very grateful for help.

Hello, its nice to have possibility to ask this questions. Few days ago something strange happens and system was hunged, i didn't do anything unusual, just web serfing, so, i had to reset system and was some astonishin because that rather rare accident. After reload i saw that my browser theme reset to default, and as remember account wasn't loginned as usual, after while i noticed that all logins and password just, disappeared... I very hope that just crash and not any hackers... And here is some pity because many of logins and passwords i mere don't remember.. What can i do in this case? Will be grateful for any help.

Running Thunderbird v. 78.4.3. When new messages are received the message window does not autoscroll to the bottom of the window to reveal the new messages. I have to manually scroll to see them. This is new with this update. Thanks in advance for your help.

TB worked normally. I applied the TB 78.6.1 32bit update to the machine (win7 pro 64bit). Outlook,com server is configured as POP3 connection and on restart of TB I got a dialog - refused to authenticate with wrong password ... My other servers appear to respond correctly. Server settings all look ok. Entering the correct password when prompted (checked by web login) does not apparently authenticate TB ...

TEST: Just swapped from pop server to outlook.office365.com with same response.

Dialog text reads: Sending of password for user xxxxxxx@outlook.com did not succeed. Mail server pop-mail.outlook.com responded: Logon failure: unknown user name or bad password.

FURTHER TEST: If I restart TB to force a reconnect with saved parameters, the Microsoft activity log for my account registers the access and logs a "successful sync" ... Doesn't this mean that it *has* actually authenticated but it is a Thunderbird response issue? I do not receive new email to TB despite the "successful sync" ...

Hello,

I've got a laptop Dell XPS 9380 that comes with an Intel UHD Graphics 620 as Video Chipset. I run in under Fedora 33 with the distro provided package (as of now version 84). The playback on some videos is choppy, I have one picture on 10 I'd say.

How can I fix that, can you point me some solution ?

thanks

Since today I can't access my Yahoo IMAP and SMTP servers, neither with TB 78.4.0 nor TB 68.12.1. The access to Yahoo's POP3 servers is possible as I have still one Yahoo e-mail account which uses POP3 server.

Yahoo had announced that they will restrict the access to their e-mail servers for "outdated Apps", but to Thunderbird this restriction should not apply.

Things I've done so far:

• allowed cookies in "Privacy & Security" (was already set)
• deleted all old passwords
• tried to change authentication method to OAuth2 both on IMAP and SMTP servers, worked for the IMAP servers only

The following errors occur:

• TB just says "Couldn't connect to server imap.mail.yahoo.com", and that's it. No "Enter password for server XYZ" dialog is shown
• I can't change the authentication method for SMTP servers to "OAuth2", the option is not shown in the drop down list
• since one of my Yahoo e-mail accounts (which is accessable via POP3) is working with TB, I've tried to access my other Yahoo accounts via POP3 servers instead of IMAP servers, but failed

I would be grateful for any help and ideas.

I was advised to refresh Firefox as it's slow to start, but I'm concerned that all my downloads will be deleted. Is this true, as many of my downloads are very important to me.

Hello, I am a Thunderbird user for many many years now and I am a fan. But, i have a problem that occurred a few weeks ago is actually the first I have never encountered.

For information, i have Thunderbird 78.5.1. When I receive an email with an attachment in pdf format, I see ".pd_" instead of ".pdf". For word ".doc_" instead of ".docx". All extensions are ending with "_". So system can not be able to open them until i rename them.

I have searching along a week for any solution for this issue, but nothing found. Thank you in advance for your help!

When attempting to access https://signup.gmx.com I get the following error;

The requested URL was rejected. Please consult with your administrator. Your support ID is: < 3522328377538005653>

I contacted GMX and they have been unable to tell me why I can't access their signup page. I had my brother do a test from his home. He's on a different ISP. He is using a VPN, but this worked off VPN too. He is using the same ESR version of Firefox that I am, and he's on the same Windows 10 version I am. Also, he's using the same router I am with the same firmware. He can access the page without issue.

What I've tried;

• ipconfig /flishdns
• Checked my IP address is not blacklisted.
• reboot router
• power cycle NTD
• Run Firefox in safe mode
• Clear all cookies and cache data
• Create a new Firefox profile
• Disable Windows private and public firewall
• Rename hosts file
• Disable all firewalls in the router
• Tried different DNS Servers
• Tried different NICs (My PC has 3)
• Rebooted switches
• Checked PC for viruses/malware
• Tried different PCs in the same household
• Tried a different ISP
• Followed suggestion on https://appuals.com/how-to-fix-the-requested-url-was-rejected-please-consult-with-your-administrator-error-on-windows/ with the exception of "Add to trusted sites" I don't run any Microsoft browsers
• Read through this: https://support.mozilla.org/en-US/questions/1197304

I do not get this error for any other site. I've been trying to access this page on and off for about 6 months. It doesn't appear to be a temporary error.

Any ideas what might be causing this? thanks
