Firefox has gone crazy since last update

已張貼

That's the only way I can describe it. I think I am the victim of some sort of malware directed at Firefox.

This afternoon I was browsing in Firefox when I suddenly got a message -- supposedly from Firefox -- that said I must install an update. I wasn't thinking clearly; I should have asked a few questions. But I was involved in my online research and didn't stop to think. After the update (a .js file, for what it's worth) was installed, I noticed that the downloaded file was erased from my Downloads folder.

Suddenly I couldn't access my AT&T email, or my AOL email. For AT&T I kept getting a message saying, "Your connection is not secure! The owner of loginprodx.att.net has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website." But I can access my AT&T account through several other browsers.

In addition, the page display in Firefox is now pure text. It's impossible to navigate through the pages.

I uninstalled Firefox, and did a system restore, then downloaded the latest version of Firefox but that didn't help.

Please see the two screenshots I'm attaching.

I downloaded the "Troubleshooting Information" at the bottom of this page, but Windows doesn't know how to open it.

I'm running Windows10, and I have plenty of memory, etc.

Help!

Thanks!

被選擇的解決方法

I think I solved it.

When I uninstalled Firefox, a folder named "Old Firefox Data" was placed on my Desktop. On a whim, I simply copied all those files into my new Firefox Profiles Folder. Much to my surprise, when I re-opened Firefox, it now seems to be working fine. (Fingers crossed!)

James -- I knew as soon as I installed the "update" that I had made a mistake, but, as I said in my first post, I was concentrating on what I was trying to do on the internet and not a bothersome message that appeared to be from Firefox. Lesson learned.

Thanks for you help.

The firefox-patch.js files was not from Mozilla or the Firefox web browser. The random name of the website alone should raise a big flag that it was not legit.

The Firefox updates are done internally in Firefox (with a .mar type of file) whether on Windows, Mac OSX or Linux or by download from mozilla.org like say www.mozilla.org/firefox/all/

So you run this firefox-patch.js file or just saved to disk?

As for connection not secure, two common causes is due to system time/date being incorrect and due to your antivirus client trying to help you by inserting its own certificate and instead causes this problem. https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER#w_the-error-occurs-on-multiple-secure-sites

Though if you did run this fake firefox-patch.js filet then this could be the culprit.

Hi rontiara, the Old Firefox Data folder on the desktop usually is created when you trigger the Refresh feature. I wasn't aware that running an uninstall could create it. Maybe it was a coincidence?

Now that you mention it, I did a refresh, but then uninstalled Ffx after the refresh didn't help.

I'm glad I did!

BEWARE!! I have had this notification pop up several times since my original post. This is a screenshot of the latest one. I was on an AP news website (http://bigstory.ap.org/acd35036b9844574a80cd3b4a2eebcb3?utm_campaign=SocialFlow&utm_source=Twitter&utm_medium=AP) when this popped up. Note that the URL was redirected.

Well normally Firefox users on Windows do not encounter this however once they do they have a increased chance of encountering it again one or more times.

Using a ad blocking extension such as Ublock Origin can help block these malicious ads. https://addons.mozilla.org/firefox/addon/ublock-origin/

What a difference! Thanks for your advice, James! At last count it blocked 93 ads today! Wish there were some way to find out about these really helpful add-ons without wading through an endless list of "must-haves"!
