Diễn đàn hỗ trợ Firefox

Hi,

I've been using malwarebytes for a few years without any problems but now I'm getting this message when browsing to any web site Any idea why this is happening ?

support.mozilla.org is most likely a safe site, but a secure connection could not be established. This issue is caused by Malwarebytes Web Protection, which is either software on your computer or your network.

What can you do about it?

support.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

   If your antivirus software includes a feature that scans encrypted connections (often called “web scanning” or “https scanning”), you can disable that feature. If that doesn’t work, you can remove and reinstall the antivirus software.
   If you are on a corporate network, you can contact your IT department.
   If you are not familiar with Malwarebytes Web Protection, then this could be an attack, and there is nothing you can do to access the site.

Error code: MOZILLA_PKIX_ERROR_MITM_DETECTED

Hello. It would be good to get "Close tabs to the right" and "Close other tabs" back from submenu to the main menu and get an option to assign keyboard shortcuts for those commands. This would take just one line more and save a lot of time. Thanks.

Hallo zusammen (sorry - not in english), kann man Firefox so einstellen, dass eine heruntergeladene Datei in einen bestimmten Ordner (nicht temp) gespeichert und gleichzeitg auch mit einer bestimmten Anwendung geöffnet wird? Für Eure Hilfe bin ich sehr dankbar. Viele Grüße HP

Hi,

Im struggling like hours on getting a http connection to a private webservice of mine... Firefox always redirect me to https://example.com instead of http://example.com.

I tried following solutions: - delete whole cache - Start Firefox in Safe mode - removing all extensions - setting this in about:config:

   security.insecure_field_warning.contextual.enabled = false
   security.certerrors.permanentOverride = false
   network.stricttransportsecurity.preloadlist = false
   security.enterprise_roots.enabled = true 
   browser.urlbar.autoFill to false in about:config.
   browser.cache.check_doc_frequency from 3 to 1. 
   urlbar.autofill false
   browser.urlbar.trimURLs false

- restarting firefox - restarting computer

And still this damn brower redirects me to a https site!!!!!!!!!

Searching for a solution since 4 hours. Please help me!

Keller Williams website is not working properly, images aren't showing. It shows the lock is secured. The screen is white & nothing is popping up on the screen. I don't' know if I changed something regard the blocking of Firefox browser settings. Please let me know: Here's the website- https://www.kw.com/ Keller Williams Madison website is the one that I'm trying to use.

Firefox started to run an update. I immediately got the Parsing error: undefined entity Location: chrome//browser/content/browser.xhtml Line number 741, Column 15:

I can’t even get to the browser homepage; sending this on my phone. All I get is a gray dialogue box with the message.

Have rebooted. Try to open Firefox, reappears. This originated with Firefox automatically uploading an update without giving me an option to do later.

Cannot access a browser page to download anything.

In the past month I have begun receiving the following message for websites that I use regularly. These are very common company sites like American Airlines and Disney.

Access Denied You don't have permission to access "http://disneyworld.disney.go.com/" on this server.

Reference #18.cd7519b8.1600969130.8913347

I am trying to figure out why access is being denied and if this is related to Firefox.

Thank you for your help.

I mistakenly deleted the subfolder "History Older Than 6 Months" under the main "History" folder. How do I restore that folder? I was trying to determine how to delete all that history in that folder since there are a lot of them all at one time instead of a page at a time. I searched through other support items but didn't find anything that addressed this. Windows 10, latest Firefox.

Firefox refresh deleted everything, I don't have my browser history nor bookmarks and saved passwords, why did guys lie and vague recommend something that would delete everything just cause internet was slow without warning? It even said it would keep the history and bookmarks so that's another lie. And I can't get my old data back in my profile, so I want to know the phone number for firefox customer service or tell me in clear layman terms how to get my browser history back in firefox.

The browsing history works fine, with one exception: once you click on an older link to reuse it or even to simply look at it, the older link is removed an replaced by the new one.

This is very disturbing whenever you need the older link's timestamp as a proof you accessed the corresponding page at a given time.

Is there any possibility for the user to avoid this behavior?

The browser saves any downloaded filesto the system "Temp" folder, not to my chosen "Downloads" on the system drive. When you select the "Always prompt for path" option, nothing changes. What could be the problem and how to fix it?

Hello

Mozilla Firefox (64-bit, US English) is UNABLE to load the website, https://www.pressreader.com since at least version 78. I am using version 81.0 now and the problem persists.

Strangely, Mozilla Firefox (64-bit, Simplified Chinese) is ABLE to load said website. Mozilla Firefox (64-bit, Japanese) is also ABLE to load said website.

What is happening?

Below are the relevant details:

The HDD of my desktop computer has 3 primary partitions on which the first is installed with Microsoft Windows 10 (64-bit, US English), the second contains Windows 10 (64-bit, Simplified Chinese) while Windows 10 (64-bit, Japanese) is installed on the third. Each operating system is installed with the appropriate 64-bit language version of Firefox.

The settings of the 3 language versions of Firefox are IDENTICAL.
