Firefox Support Forum

I have 3 Firefox windows open. Suddenly, one window is hidden until I click on the icon. Clicking on the icon switches the screen between the one window, and the other two windows and my mail program.

I install Firefox today in a object for download google drive videos but even I can't open mp4 videos getting message "This video format is not supported." How can I fix it?

I have recently been encountering issues with Twitch.tv that were not present even two and a half weeks ago. I keep getting a blacked out screen with an "error #3000" message. The only known website that seems to deal with the issue comes at the problem from the idea that people are trying to access the site via Chrome. The few options they suggested that I can apply to my machine— clearing the cache and cookies or else using CCleaner offered no help.

This is not consistent however, as some other twitch channels I go to work perfectly fine. It's worth noting that I was not encountering this issues with Firefox version 78.0.2, while I am currently on version 79.0, and this is the version that has brought this issue up. Should I try downgrading to the previous version and see if that helps, or what?

Does anyone else get this error message, and if you do, what did you do to fix it? The few things I could try, I already have, save for turning off the hardware acceleration, which I don't think is the problem, as if it were, I would have seen it weeks ago when this wasn't an issue.

I am including a screenshot of what I'm seeing.

I logged on to Firefox and searched for information on my Apple i-phone SE 2020. I received information titled "i-phone User Guide" It is about 20 pages. Now I can't get rid of it. It shows up every time I try to log on Firefox and I can't go any further with my log in. It shows up when ever I click on the Firefox App. I am using Windows 10, it seem like it has taken over the Firefox entry screen.

When reading articles in Facebook if a video plays the screen goes black with the message Sorry we are having problems playing this video or I get the message without it playing. I Have the latest version of Windows 10. If I go to my iPhone or iPad the video plays. This is beyond irritating.

I have a private message board and I am having problems with the messages not marking as read. Sometimes they mark and sometimes they don't. If they do not mark I refresh the page and they show as marked. I thought it might be just one computer but all three are doing the same thing. I started with the 77 version of Firefox. I replaced my router because of other problems. I took one of my laptops completely removed Firefox by deleting everything mozilla in appdata and sub directories. I went into the registry and deleted everything mozilla. I then reinstalled Firefox, left it as a fresh install. Booted my computer in safe mode with only network. I then launched Firefox and it is still doing the same thing not marking the messages as read by changing color all the time. Like I said sometimes it does mark them and sometimes it doesn't. I am running the latest version of Firefox. Microsoft Edge and Internet Explorer no problem marking as read. Does anyone have any more suggestions to try.

I run Firefox on a Macintosh. I have Notifications always active in my Macintosh menu bar (upper right corner). Suddenly without warning, and without me doing anything, I got two notifications both saying: "Firefox is downloading from OneDrive". No indication of what was being downloaded, to where, or why, or why now. In fact at the time, I was working in Excel not Firefox (although Firefox was up, just hidden). OneDrive was up also, but in the background doing its usual syncing stuff. I checked Tools --> Downloads. I got the message: "There are no downloads." What the hey? Considering Firefox is a Mozilla product, and One Drive is a Microsoft product, I'm not sure how they can even talk to each other. Should I be concerned? Is this a virus? How can I find out what was downloaded, where it went, and why did this happen? Hope You Can Help.

I have had to change the Search Engine back multiple multiple times after changing to DuckDuckGo and removing the others!

Why does the system Windows 10, if that is the culprit continue to change it away from DDGo? I removed the Microsoft Edge File from my Computer. It used to be the one that replaced it!

Help

I use Xubuntu OS and installed Firefox from there many 4 months ago on this my new laptop, from Ubuntu repos. I now do not know what version it was.

About a month ago I noticed that every time I closed down the computer I saw a flashing image of what appeared to be a message from Firefox. It disappeared before I could read what it was about.

I uninstalled Firefox totally yesterday by purging the system, deleting the folders/files in /etc and /usr relating to it. I downloaded it from repos and installed it again However, the flashing image still appears every time I close down.

I decided to video the close down to pause it and see what this message was about. It was as I said in the subject above. I found two crash reports in about:crashes and have submitted them.

Please tell me how to stop this repeating message.

Also, when uninstalling Firefox I saved the logins and passwords but was unable to use the resulting csv to recover them. Is there a better way than manually?

I have three browsers on my Dell Latitude E 6320 Windows 10 operating system namely Edge, Firefox and Google Chrome. Firefox is my favorite browser among the three which has been working normally untill a fews ago I decided to make Firefox as my default browser.

Of recent when I click on the Firefox Icon to surf the internet, a small window appears making reference to drive C:\windows\system32\......... with something like .dll at the end of the path and some statements which disappear before I can completely read the contents of the small window. As the small window disappears, Firefox launches up and remained launched with nothing else happening. Even when I type Firefox address in the address bar and press the enter key, nothing happens. The text message "Hand shake" with any site address typed into the address bar that is usually displayed at the lower left handside of Firefox page before the required website is connected and displayed, is no longer been displayed. I have uninstalled the 79 version and reinstalled the same version which I have just downloaded for resolving the problem, thinking that the uninstalled one has been corrupted, but the problem still remains.

This is the problem I am experiencing with Firefox browser presently hence I am asking for assistance of how to solve this problem from the community.

Thank you and for looking forward to your response.

Hello,

1) In the past, the pages that were visited the most were updated, and accordingly fewer to hardly visited websites were pressed down or disappeared completely from the address input list, where is this feature going ?

2) And can you keep only 9 web pages in the address line, how can i change it, are there options for this ?

Thx.

When i try to look at an image on firefox in it's own tab so i can see it bigger, it instead opts to download it instead of just showing it in the tab itself. This is annoying as I don't want to have to make a whole folder just for images that i've seen once and then never look at again. is there an option i might have chosen at some point that enables this? i'm not too sure. please help if someone is able to.
