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?

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.

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.

Hi There

I want to copy all youtube music videos urls and hyperlink to excel 2013. This add on is not available with this version, is there a substitute?.

Thank You Paul.

I want to import everything from avast secure browser, but ASB does not show in the browsers option. Is there a roundabout way to import everything(passwords, bookmarks etc)?

Working on a desktop with Windows 11. Problem is: search bar at top of my Firefox only intermittently brings up results. I can type something in there and it appears to be searching, but nothing comes up. Occasionally, if I hit it again it will bring something up, but not often. Google is the browser.

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.

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 have the issue that when I enter a website that is in English, I sometimes get a little Google translator pop-up at the top which asks me to translate the page. As I am fully fluent in English, I would like to disable this but the option "Disable for English" does not seem to do anything, as this keeps happening. I can disable it for an individual website but I would like to disable it completely.

I'm also confused because within Firefox I have only selected US English as a preferred language. My laptop itself is set to German.

I don't have any translator add-ons installed and can't figure out where this pop-up even comes from, let alone how to fully disable it.

If anyone could help, I'd be very grateful!

i updated firefox yesterday and since then i have had nothing but problems. it freezes, hangs, stops responding and basically wont work. if i click on a tab, it wont open. if im typing in something on a website, it stops typing. if i try to close firefox, i cannot. i have restarted firefox as well as my computer a dozen times. NOTHING WORKS!!! This is a serious problem for me. Short of uninstalling firefix and installing a different browser, what do i do?

Received the following message. Repeated the access and still have the same problem

Access Denied You don't have permission to access "http://www.lowes.com/" on this server.

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.
