Firefox 技術支援討論區

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.

My volume on Youtube is often too low. Some time back I got a java script that fixed it. I had to do an F12 and paste it in somewhere and then I got a little rectangle at top left which said something like 'volume'. Click on that and up went the volume. Click again, up more and so on. It was good. Sometimes on things like perhaps Bitchute it wouldn't work. It would actually switch all the volume off. I'd refresh the page to fix that. Anyway: it suddenly disappeared today. The little rectangle is gone. I can't up my volume on Youtube any more. I got something from the web, a javascript, and pasted it into 'console' after F12 but i got error messages. I'm clueless. Don't know where to look for my original, see if it still there. Don't know how to troubleshoot. Don't know any other way to get the volume up. See error message on the console whenever I go there, don't know what to do about them. FYI I'll post the first few lines of them: Unknown property ‘-moz-osx-font-smoothing’. Declaration dropped. screen.4472f725724c6a0a.css:1:3751 Unknown property ‘zoom’. Declaration dropped. screen.4472f725724c6a0a.css:1:6665 Unknown property ‘zoom’. Declaration dropped. screen.4472f725724c6a0a.css:1:14230 Unknown property ‘zoom’. Declaration dropped. Don't know what that's about. But mainly: how to get my volume up?

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.

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.

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.

Title sorta says it all. The other day when I opened FireFox on my laptop it said my account had been disconnected, and to re-sign in. In a long story short, I did not have my phone for several weeks and it was dead. I received it afterwards, did not allow it to connect to the internet, and still have that old profile data on my phone.

Can that data safely be retrieved or re-synced to my account? If so, how? It would be iPhone to Windows 11 install.

Respectfully, Michael

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 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!

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 have my MacBook Pro, did not change anything recently, always used Firefox as my default browser, but now all the searches went from Google to Yahoo; I did not change anything and everything is up to date.

While using Firefox all of my non-pinned tabs disappeared suddenly. The History -> Recently Closed Tabs item in the menu was greyed out. How can I get these tabs back? I have not closed the browser yet.
