How do I block autoplay vedio?

I know I can block Audio and Video, but I just want to block autoplay video. As if I use the block audio and video it will mute all videos I open, and I need to unmute it every time. I just want autoplay to not start, not mute the video too.

Within the last day or two, Firefox has started opening the sidebar whenever I press "ctrl", which has caused a lot of annoying misclicks and prevents me from using "ctrl+" functions (e.g. new tab, cut, copy, paste, etc.).

How do I disable the sidebar? The instructions at the support page titled "Use the Firefox Sidebar to access bookmarks, history and synced tabs", specifically the subsection titled "Toggle the Sidebar on and off" (https://support.mozilla.org/en-US/kb/use-firefox-sidebar-access-bookmarks-history-synced), are unhelpful at best and incomprehensible at worst.

This problem is incredibly frustrating, and has even impeded me writing this request for help, since I couldn't use the keyboard to copy+paste the article title and URL.

TL;DR Please help me (permanently?) disable the sidebar from appearing.

I recently installed Firefox 102.0.1 64-bit on a new WinX laptop. Using the same link as always (http://www.henderson.lib.nc.us/) I am unable to connect with my county library. I'm not having trouble with other sites. The error message says

Secure Connection Failed

An error occurred during a connection to www.hendersoncountync.gov. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I turned off HTTPS-Only Mode but the problem persisted. I also tried entering this site as an exception for HTTPS-Only but that didn't help. Even after restarting the computer, Firefox continues to reset the URL to HTTPS from HTTP. My wife was able to access this website on her desktop WinX with Firefox and no problem. On my WinX desktop with Firefox I connected to https://www.hendersoncountync.gov/library instantly.

Is the HTTPS-Only Mode sticky? What am I missing?

I have Firefox installed and set as my default browser and yet my Registry shows the following: Open with Application Issue "C:\Program Files\Internet Explorer\iexplore.exe" %1 HKCR\ftp\shell\open Open with Application Issue "C:\Program Files\Internet Explorer\iexplore.exe" %1 HKCR\htmlfile\shell\open Open with Application Issue "%ProgramFiles%\Internet Explorer\iexplore.exe" -nohome HKCR\VisioViewer.Viewer\shell\open

Since Firefox is set as my default browser I would have expected to see Firefox here in these registry entries as my default browser in lieu of Internet Explorer. However, if I delete those Registry entries, it then breaks any embedded links in MS Programs such as Outlook mail and Excel. I have I.E as non-active (i.e. unchecked in Programs) but the system still seems to rely on I.E for opening any embedded links. Any suggestions as to how to fix this problem would be appreciated.

Hello Mozilla:

My fb account has been hacked. When I try to follow the procedure for regaining control provided by facebook, I get a pop-up window which asks for a security key via windows/mozilla. I don't know what this is or where to find it. Can you help?

sincerely,

Hi I'm developer and i develop a site and when i QA it all are good in other browsers expect Firefox,some colors are different in Firefox,images are not displaying, in text fields there are little arrow icons, widths & heights sucks in some content why the hell is that i think Firefox is suck now i have to wast time to write other CSS file when some one comes with Firefox that need to change content.

I use/like the randomly-generated 'strong' password feature, but is there a setting/option to have it include one or more special character(s)? So many sites nowadays require one, and VERY few *prohibit* them. I know I can 'substitute' one in there, but I'm VERY lazy! Thanks.

I got a phishing e-mail on my mail.yahoo.com webmail interface. I deleted it but immediately received the following warning from Bitdefender:

Suspicious connection blocked 8 minutes ago

Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an untrusted certificate to realitychance.com. We blocked the connection to keep your data safe since untrusted certificates are issued by unrecognized Certificate Authorities.

Kinda weird that an e-mail where I didn't click any link is still able to manipulate my browser like that!

Hi there, I keep getting an error message when I try to login to some secure access websites that I use for work purposes.

I get the following error report with no code #:

"Secure Connection Failed An error occurred during a connection to (website). The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem. Learn more...

Try again"

(*this always fails).

This is only an issue on my laptop. If I use another computer I can access the website without issue.

How to I fix this issue on my laptop?

Thank you,

I received a file this morning or yesterday that states its a firefox file called _I7zEKnU. Was that from firefox? I'm concerned my computer might be compromised. Thank you.

Olá

Devido ao fato do Chrome não manter minhas credenciais e toda vez que eu iniciava este browser eu tinha que fornecer meu login e senha além do fato do Suporte deles não ter resolvido o problema, eu decidi mudar para o Firefox apesar de não ser o mais legal nem prático e intuitivo para se navegar como o Opera e o Vivaldi, mas sim por popularidade.

-O problema: Desde ontem, a página do Gmail não abre, isto é, mostra uma página totalmente em branco conforme anexo, apesar do link estar correto e, na verdade, eu utilizar os links dos Favoritos para diminuir a digitação e aumentar a agilidade.

-Minhas tentativas de solução: Eu desabilitei todas as extensões do Firefox (eu eu já utilizava mesmo antes do problema ocorrer); Eu executei uma limpeza geral utilizando o CCleaner; Eu abri o Chrome e, para variar, me loguei (por causa do problema mencionado acima) e a página do Gmail é exibida corretamente com todos os e-mails de hoje; Eu copiei este link do Gmail, no Chrome, para utilizar no Firefox porque estavam diferentes mas mesmo assim o problema persiste.

Acabaram as ideias

Obrigado

PS: Como inserir mais imagens porque só uma é permitida?

english: Hello

Due to Chrome not keeping my credentials and every time I started this browser I had to provide my login and password in addition to the fact that their Support didn't solve the problem, I decided to switch to Firefox despite not being the coolest not practical and intuitive to navigate like Opera and Vivaldi, but by popularity.

-The problem: Since yesterday, the Gmail page does not open, that is, it shows a completely blank page as attached, although the link is correct and, in fact, I use the Favorites links to reduce typing and increase agility.

-My solution attempts: I disabled all Firefox extensions (I was using them even before the problem occurred for the first time); I performed a general cleanup using CCleaner; I opened Chrome and for a change I logged in (because of the problem mentioned above) and the Gmail page displays correctly with all of today's emails; I copied this link from Gmail, in Chrome, to use in Firefox because they were different but the problem still persists.

the ideas finished

TY

PS: how to insert more images because only one is allowed? (joined printscreens)

When logging in to https://login.amwater.com (American Water, a large Public Utility), receive the attached message. Site refuses to proceed, insisting that users switch browsers to Chrome or Safari. Is this the beginning of the end? Thanks for any help. Running Win7, FFx 102.1
