Firefox 技術支援討論區

I was browsing as normal when I navigated to a site I have been to many times and that I consider reputable (Etsy) and the browser immediately went to a screen that said something about how Firefox had done updates in the background and I needed to click a button to "Restart Firefox." Obviously this looked fishy to me and I didn't click; instead I killed Firefox via the command line and then restarted it. When I did, one of my windows didn't look right (I had two windows open, each with several tabs)-- the tab bar at the top just cut off halfway through one of the tabs instead of me being able to scroll over. In addition, right after I was playing a game on my computer and part of the game board froze. Now everything seems normal. Is it possible I managed to end up with some malware even though I didn't click on the link? Has anyone seen this particular scam before?

Thank you!

Always when I start my computer Firefox opens and I don't even have Firefox installed on my PC. I can't see the tab but it has a weird description. Has anyone encountered something like this ever again??

I downloaded a malicious add-ons extension called "YouTube to MP3 Convert Button" by "Firefox user 6248547". All it did was open a video conversion website, which worked for the first video I tried (with alot of popups) but the second video I tried, it redirected me to a fake Firefox update page. As soon as I tried to cancel it, a login popup kept appearing and all my open tabs immediately went haywire trying to do some kind of redirect, and I it would not let me click on anything. I quickly ended the process to force close the browser, restarted Firefox and cleared my cache and uninstalled the extension. I am concerned about what kind of malware this may have installed on my machine. I reported this user over a month ago, but it is still available on the add-on page, and other people also commented about it having malware. Any suggestions?

Hi. I have a problem with http://metagmae.org/page/ and I have no idea how that came to me. No matter what I do, nothing can help me to avoid that thing. It auto-starts Firefox and tries to get more information. It is said that it is a virus. And I can't delete it from Firefox because I can't find it. Can you please help me to solve this? I uninstalled Firefox and deleted everything but when I installed it back, it came back! It is terrible and makes me crazy. Please help me with that. I love Firefox and it is now almost 15 years I am using it. I started with Firefox 6.0 or something.

On 7/9/19 when trying to sign into a website, which I've used for years, after I enter my credentials and click 'sign in' FF downloads "webgate.dll" and does not proceed. I am able to successfully log in using Chrome or IE. I most recently accessed this website via FF last week - no changes to extensions since then.

Using FF Quantum 67.0.4 64 bit

I received a notification to update the Flash Player on Firefox. It doesn't look official so I did not click install. The manner in which it behaved after I tried to get rid of it confirms my suspicion that it's a scam. Upon clicking the hyperlink that says "Do not show this notification again" a banner appeared at the top left of the click asking me to allow the update. I clicked no but it continued to appear. In fact, it appeared multiple times until closing Firefox thru the task manager. However, when I opened Firefox afterwards the same prompt to upgrade Flash appeared right after opening Firefox. I can't stop this so I have stopped using Firefox. I checked the regular Firefox upgrade dialog thru about Firefox. It upgraded Firefox to version 67.0.2 with no Flash player update Then I ran a Malwarebytes scan. The result was "no threats detected." Have other users faced this problem? What should I do?

For 6+plus months, I get "popups". The latest shows a box in middle of screen that is in what appears to be another window. The small window has a message "Firewall has defined that your Windows Microsoft system is damaged and irrelevant. ...." plus other junk. No trade marks or anything to identify from whom. In the background, in what looks like another small window but in fact is full screen, it shows System Warning! in blue band around message starting with a "red x Your Windows system is damaged ...." that is partially hidden by the above message.

In the header where normally there is something about the site and an x to close tab, there is only the x. Also, in the address bar, it shows the i in circle, the green locked lock and the address.

Usually, I just shut down Firefox without clicking on screens. I would then restart Firefox which brings up a message "Close Firefox" with the following ? in a circle with message - "Firefox is already running, but is not responding. The old..." with choice boxes to close or cancel. This did not appear in lastest popup.

My settings are that Firefox on closing does not save anything.

The time before was a screen that told me on a specific date, my subscription to McAfee expires, unless.... Only trouble was I don't have a subscription!

The time before that was a McAfee back screen with a small window up front stating "Windows Security Center. Your Mcafee subscription has expired.... " with the choice window "OK".

Only just learned how simple it is to take a screen shot. I used my phone to take photos previously.

Oh and the time before above, there was a popup with Firefox logo and "Dear Firefox user, You re today's lucky visitor for: Feburary 4, 2019 ...".

I have seen multiple times these messages.

I have uninstalled and re-installed Firefox more than once. I just recently did a fresh install of Windows 10 Pro on a reformated M.2 drive. But I have a HDD with most files that I did not touch.

HELP!!!!

I used Firefox to go to lowes.com website. My computer locked up with a page indicating Microsoft had taken over the system and to call <scam phone# removed> to get system unlocked. I have uninstalled Mozilla program, and re-installed again several times. Always the same problem. When I use windows explorer, computer is OK; Does not lock-up.

I've been having issues with Firefox on Ubuntu 18.10 for a while now. For whatever reason, whenever I try to access maps.google.com it states that the website is unavailable, whereas that maps.google.ca redirects to ww1.google.ca which, in turn, redirects to mediadiscovery.net - which is a website blocked by my router's adblocker. When I use Chromium or Vivaldi, I don't have that same issue, the website is completely accessible; also, if I instead use www.google.com/maps then I actually reach Google Maps from Firefox. I've already tried clearing cookies and cache, as well as restarting Firefox fresh. I only have one extension enabled (GNOME Shell Integration) and 3 plugins (OpenH264, Widevine and Shockwave Flash).

Any help is much appreciated. Also, I got the troubleshooting information while running in Safe Mode, which had no impact on the behavior I previously described.

I have used Firefox for many years and am always current, as I am with Windows 10, but the last few updates have caused major problems:

1. At times I get a red screen Firefox Critical Error which usually locks up my PC. Sometimes I can free it up with Cntl/Alt/Del, but sometimes I cannot even shut down, have to physically unplug the PC. The screen says to call a phone number for Microsoft support, but this is a 3rd-party company selling software which has somehow compromised Firefox. I reported this before but no one seems to be doing anything about it.

2.Although I have checked Block pop-up windows under Permissions, I now get suspicious pop-up windows the first time I click on many web pages. If I immediately close these, I can then use the page fine. Is there something else I need to do to block these pop-ups?

At various points in my usage of Firefox, if my default home page isn't ChillTab, and even sometimes when it is, Firefox will randomly quit and restart with ChillTab as the default. Virtually every single time it has happened I was in the middle of watching a video. What's worse is that Firefox will demand updates so as to change the homepage to Yahoo.

My home page is now set to (http://securedsearch.lavasoft.com/?pr=vmn&id=webcompa&ent=hp_WCYID10420__190321) when i went to options my Homepage and new windows option is disabled!!! I cant change any thing, i even uninstalled the software from windows and checked for unwanted adons in firefox and found none...

I was tricked into downloading a fake flashplayer update that included the adware "pro search tip." I've been able to uninstall it from my other browsers and firefox and it doesn't appear anywhere on my machine. I also used sophos to scan my machine, which deleted it. But it still redirects my default search engine to itself in firefox.

I have https everywhere activated, and ad blocker as well.

Since yesterday march 30, 2019, every time I want to make a research on google through Mozilla, or directly by a site address, a very unpleasant searcher "chissk.icu" appears instead of the usual research by google. I made a cleaning of my PC by malwarebyte and I have also ccleaner pro installed on it but they did not suppress this virus. Can you help me ? Thank you (Sorry for my english : I am french)
