Firefox Support Forum

The remote Windows host contains a web browser that is affected by multiple vulnerabilities. Description

The installed version of Firefox is affected by various security issues, some of which could lead to execution of arbitrary code on the affected host subject to the user's privileges.

Solution Upgrade to Mozilla 1.7.1 / Firefox 0.9.2 or later Upgrade to Mozilla 1.7.3 or later. Upgrade to Firefox 1.5.0.9 / 2.0.0.1 or later. Upgrade to Firefox 1.5.0.11 / 2.0.0.3 or later Upgrade to Firefox 1.5.0.10 / 2.0.0.2 or later Upgrade to Firefox 1.5.0.12 / 2.0.0.4 or later

Where are the patches/updates for this vulnerability located on the Mozilla homepage?

I go to youtube, open a video and the audio plays just fine, except there is no visual. The video says its playing and I can hear it normally but I can't see anything. Subtitles show up, but the place where the video is supposed to be is just blank, the same as the background of the page. Weirdly if I click the settings button on youtube, the one next to the sign in or account button, the video will display as long as that menu is up. If I close the menu the video goes away.

I have refreshed firefox, deleted and reinstalled firefox, removed all my extensions, turned hardware acceleration off (and then back on when it didn't work) as was recommended in a similar post a few years ago, and restarted my computer. Youtube still won't show me a video. It works fine on chrome, just not firefox.

I uploaded a screenshot of an ad, which doesn't play but shows the outline of the video player, a screenshot of a normal video where the area the video should be in is just more indistinct background, a screenshot of the video appearing normally when I have the settings menu open, and a screenshot of the captions loading properly over an empty void.

Edit: I installed the Enhancer for Youtube extension? Which I haven't ever installed beofre? And now Youtube works? Why

2nd Edit: Its broken again. I changed literally nothing, just restarted my computer for an update but im getting blank screens again

Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly.

Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked.

I am attaching pictures of how the error shows.

Please Help.

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

In my MS Windows 11 system in control panel, Apps > Default apps. Firefox is listed twice. In both of these there are these two separate listings: ".htm" and ".html". Below both these listing it says: "Firefox" "Firefox HTML Document"

Question: Can I remove/delete/uninstall one of these Firefox's? Question: Should I remove/delete the ".htm" and just leave the ".html"?

Hope this makes sense. Thank you for your help.

I'm trying to download Firefox on a new computer. It downloaded the install program at least 6 times in about an hour, but it never finishes downloading. How can I avoid this and get it to actually download Firefox?

I've just noticed whilst writing a blog on wordpress that my firefox built in spellchecker is no longer working. It no longer works on wordpress. It no longer works on any other page, including this one. Here is an example sdhflakshfldfjl - included in the files below. Thanks in advance.

I loved Firebug and really miss it a lot. The one thing I have a had time with and having to "type manually" is when I select and element in Dev Tools related to CSS. When an element is highlighted and I click the + sign, it does not present the exact CSS code. See screenshot.

In Firebug, I could click that and the + sign and that same exact code would appear on the right. But it does not. It's some modified version and I always have to update the code.

If there something? Also, in Firebug, I could right click that element at the bottom and copy it. I cannot do that. It doesn't allow me to copy it.

This is really slowing me down and I don't like to use a lot of add-ons in the browsers. Thanks in advance.

the start up section is not working every time i open firefox its blank again .all i want that whenever i start or open firefox i want to resume my work but its all goes everytime i open firefox all the previously open tabs are goes every time please fix this issue i have the open previous window option on but it still clear the tabs why

Just recently I have noticed that the Closed Caption is way out of sync when streaming Prime movies on my PC. CC works fine in Edge, but not Firefox. Looking for some things to try to fix this.

I placed an order through Firefox with Jockey.com on 05/31/2023 and now I cannot find the order. My credit

card information was on this order,,,

As of a few weeks ago, I can no longer copy and paste when using Outlook for emails with Firefox as the browser. I have no issues if I use the MSN browser. When using Firefox, I can copy and paste in the subject line but not the body of the text. This is a real pain! I had no issues until a few weeks ago. If I try to copy and paste, I am able to copy but when I right click I no longer get a "paste" option. I now have an emoji option in its place. What's up with that?! I am using Windows 11 as the operating system on a Dell computer. Thanks in advance!
