Diễn đàn hỗ trợ Firefox

I have recently had a pop up open whenever I open a news page from the site MSN. It says You have chosen to open impression. Which is application/octet-stream from : https://impression.link. Then it asks what firefox should do with this file? Two options: Open with & then a browse dropdown. Or save file. I'm already looking at the news item in the browser, so I don't need an option to open the item. And I don't want to save it. Just read it. I don't knbow why this pop up suddenly appeared but it is very annoying. My searches have found the pop up is not necessariuly dangerous, but there is no information provided on how to get rid of it. Anyone else experienced this issue? And is someone able to tell me how to get rid oif it? Thx. (Pop up image attached).

Hello, Is there a way to preserve my firefox history & bookmarks from potentially being lost while resetting my password? Its easy enough to reset. I would like to do so without losing all that I have accumulated to-date.

Thank you

Norton inserted themselves as my homepage, replacing Yahoo. I didn't request this, and I'm now unable to open some sites from e-mail. URL is supposedly unavailable. There are 6 new apps with this Norton nonsense, none of which I have any interest in. Thanks in advance for any help you may render. Terry wolfe

I wanted to change the password of my Firefox account and also generate a recovery key, but whenever I try it says "invalid password". The old password is correct, though, as I can use it to log into my account. I've tried multiple times on two computers and checked and re-checked the password, but the error message keeps appearing.

Moin, I activated the HTTPS-only mode as I used the "https everywhere" plugin so far.

But, in a very special network segment for radio amateurs, the 44-network (ampr.org) encryption is not allowed. So is there a way to configure the HTTPS-only mode in a way to say ".... but not for 44.0.0.0/8?

i prefer one configuration than constantly clicking the "continue to http site" button for the next few years.

Thanks in advanced

How and why did Facebook install a tab on my personal Royal bank account page? I am a little frustrated as to how this could happen, it only happens with the the Royal bank !

Dear All, Today, i have 1.4mo of cookiz. when i go to option page of fifox : button "delete cookiz" don't delete cookiz. and the button "manage cookiz" know nothing about cookiz or exeption.

i am under win7pro, and i have the same problem under win10pro.

with lasts versions, i have this problem ; i have not last years.

and few years ago, i had same dificulty, but solved with great next version.

what is this crumble ?

May FireFox save souls of ours computer ! Kiss

Note': Such problems do exist when all add-ons disabled and in safe mode Firefox (by "refresh firefox" option).

When Firefox is started, an advertising window would occur. The hijacked address: https://winxuan[.]jd[.]com/?cu=true&utm_source=kong&utm_medium=tuiguang&utm_campaign=t_1000623798_&utm_term=19dca519301545a6b711007896b3b333 hijacked address

Also, Ctrl + Shift + N was hijacked to the same window.

The window is strange: When I click the "+" button to open a new tab, the new tab directly opens in the previous window.

Perhaps something in Firefox itself was maliciously modified, I guess.

I am using 88.0.1 (64-bit) version Firefox on Win10.

Firefox obviously couldn't care less about users when it comes to making things user-friendly. What are users supposed to do in order to sign into their account? I don't need to enable two-step authentication, so why are they forcing me? If they think it's necessary, what is "my authentication app"? I don't have any authentication app and why do I need it to sign into my account on my PC??? Where do I get that authentication app? Is it really so hard to include a link or at least a name of that app?

When I try to login to the AT&T website it sends me a code for my cellphone. The site does not remember my browser even though I check the box remember the browser. I have tried several things in cookie settings etc. but nothing seems to work.

Dear community, I have Firefox installed on Windows with serveral user profiles. I understand that firefox caches certain inormation in the Firefox/<profile name>/cache2 directories. I know, how to clear these directories. But there is also one cache2 directory next to the profile directories directly in the Firefox folder. This directory also contains several thousand files, which seem to be updated in a similar manner as the cache2 folders in the various profile directories. I would like to know, which information is stored in that "common" cache2 and how it can be cleared. Thanks

The import of the logins and passwords does not work on new Firefox 88.0.1. I've switched to new PC and I installed the same Firefox 88.0.1 as on old PC. I tried several times to sync old PC and new PC without success.

I exported logins to a file on old PC and I enabled import from the .CSV files on new PC. That does not work neither as I got almost all imports errors. I attached the print-screen.

On new PC even when I enter manually login and password on page the password is never saved. It looks like Lockwise is completely busted. Please let me know when could you fix this critical error ?

I downloaded Scribus, an open source free page layout design application from https://www.scribus.net/

link text

I can't open this application because I get a message that says: "'Scribus.app' can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the Mac App Store and identified developers.

I searched the Mac App Store and it does not have Scribus. I can't afford to subscribe to Adobe Creative Cloud and I need to be able to create page layout designs, which Scribus can do.

How can I verify that https://www.scribus.net/ is a secure application site? How can I open the application if it is a secure link?

Thanks, Shelley

Firefox has started to default to HTTPS even when the site is HTTP In particular I can no longer log in to my D-Link router on 192.16.0.1 because it forces to HTTPS and gives:

An error occurred during a connection to 192.168.0.1. Certificate key usage inadequate for attempted operation.

Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

That's something Chrome does for ages. If I'm logged in to a local account on Windows and I want to reveal any of the passwords Chrome is storing, it will ask me for my credentials every time I try to see one of these passwords.

Firefox just shows them right away, exposing dozens of passwords to whoever might be using the computer.

I'm attaching 2 images, one from the password manager in Firefox, another from Chrome. you'll see that in chrome I'm asked for my windows credentials when trying to see passwords

I'm a brand-new Firefox user, just trying to import or recreate my login data from Chrome. Every time I've clicked "Import" from Lockwise and checked the appropriate boxes, I get a dialog box telling me that the import was successful... but Lockwise still tells me "No logins found." I do know that importation of some kind is happening because my bookmarks imported just fine. Prompts to save my logins still appear, but passwords do not get saved, as evidenced by the "No logins found" message where a list of my saved logins should be. When I attempt to create a login manually, I get a dialog box like the one used to create a Primary Password, except it looks more like a system dialog box, something from Windows rather than from Firefox (image 1.1). I've tried entering all the passwords I can think of into this dialog box--my OS password, my Firefox password, the password I'm trying to save, the password I would choose for my Primary Password if I had one--only for another box to pop up stating "Unable to change password" (image 1.2). Upon closing this box, a red banner appears stating that there was an error while trying to save the password.

One of the times I was trying to use Lockwise, a bar appeared at the top of the screen stating that I needed to use my Primary Password--which I didn't have and still don't--to access my logins. I can't remember what I did because I've tried several things, but if I figure out how to recreate that I'll update this post. I attempted to create a Primary Password from my Options menu by checking the box next to "Use a Primary Password." Even though it clearly recognizes that I don't have a Primary Password set, I still get an "Unable to change primary password" notice (image 2). I've tried resetting it, but to no avail. I have also followed the advice of all the relevant articles I could find (e.g., the help article on what to do if your passwords aren't saving), but nothing so far has fixed the issue.

Lastly--it seems like I'm getting the system-dialog-looking box about every hour or so, always twice in a row: I'll click "cancel," and then it will show up again. I also can't seem to log out of my Firefox account, as that same dialog box appears and prevents me from doing so.

What is going on here? Is there anything I can do to fix it?

I have been using Firefox for years now, but since an update a couple of months back, when I deploy a new internal site I receive an error stating that the "Secure Connection Failed" because of "Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL". There is a official workaround explaining how to bypass this issue, however it doesn't work. I have tested the same sites with Chrome, Edge, IE and it always works why is Firefox suddenly not working? Below are images of my local lab replicating the issue.

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr

I use CCleaner on a regular basis and have been for over a decade and a half now. With CCleaner, I have the ability to disable unwanted browser extensions. Typically, this works just fine but lately, I've been running into an issue where CCleaner shows several Firefox extensions that do not show up in the browser's options menu: Bing, Amazon, Google, Wikipedia and DuckDuckGo. I disable these in CCleaner like I usually do yet they re-appear in CCleaner as extensions when I open a new browser window after disabling them. Are these really some sort of hidden extensions in Firefox? And if so, how the heck do I get rid of them permanently? I don't want any of these extensions. Thanks in advance.
