Firefox 技術支援討論區

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

This page keeps refreshing itself. Clicking the Refresh X stops it:

. . . since I just updated to 78.0.1 (64-bit) . . . ? It looks like a bug to me.

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

• This happens for any filetype, from any source.
• It started happening about a month ago.
• Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
• If it's a small file and I try repeatedly, it sometimes will eventually download.
• Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
• I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

• Used Refresh Firefox
• Cleared download history
• Changed download location
• Reset browser.download values
• Disabled firewalls and antivirus/spyware
• Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
• Cleared cookies and cache
• Ran in safe mode
• Verified Temp folder filepath was valid
• Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
• Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

• I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
• Verified places.sqlite was not set to read-only
• Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

Today firsfox just stopped connecting to a wss websocket server. It has always worked fine before today and still works in Chrome.

What happened???

Port is open. Connect when running websocket.org/echo.html in chrome but not in firefox

I am in Windows 7, 64-bit. All of a sudden all of my Firefox logins and passwords are missing. I read several threads about this, which told me to check the "Old Firefox Data" folder on my desktop for the logins.json file. However, the only information in that folder is from 2018, two full years ago. Where did my logins and passwords from yesterday go?

Also, I just updated to version 80.0.1, hoping to get my passwords and logins back, but they are sill missing. The problem just occurred today, before I updated from version 79-something.

Thank you for any help you can give. This is extremely upsetting.

Hi, When I click on a link on a page, I want it to open it in a new Tab and leave the page I'm on alone.

Instead, it overwrites that page with the new one, and I have to hit the back button to get back to that original page (and sometimes the back button get grayed out and I can't get back at all).

I've tried checking the box for: Open links in tabs instead of new windows but that doesn't do it. Then I tried checking the box for: When you open a link in a new tab, switch to it immediately, and that doesn't do it either.

I know that a work-around is to hold down the Ctrl key while clicking a link, but I'd like to set it as a default so I don't have to do that.

Any ideas? Thanks!

1. I had downloaded previous PDF files using Microsoft Edge. They came up on Firefox with no problems. I was able to highlight PDF text with no problems. 2. Today, I flipped a switch to download a PDF file using Firefox and to always display PDF files in Firefox. All previous Edge PDF files immediately had their icon changed. 3. Now, I can define the PDF text I want to highlight, but there is no action to click on to make the highlighting happen in a color of my choice.

Windows 7SP1. With the Firefox 78.0.1 update, search with Amazon.com, You Tube, Facebook, Reddit, Wikipedia and Twitter appear below the address bar when I start to type the url. I only have as default DuckDuckGo and Start Page HTTPS selected in options, and no alternatives.

I saw the one reply to this issue to use the about:config, browser.urlbar.oneOffSearches, change to false. This did not work.

Why has this been done? I don’t want them and I don’t use them. How do I get rid of this?

I have been trying to watch Netflix on Firefox, I made some security changes and at first thought that I may have caused the problem, but now I see that the add-on just fails to install. It just keeps the notification that it is installing. Is there a way to fix this issue?

Hi, my firefox context menu is too miscellaneous. I want to keep "copy" and "seach...for..." entries, and delete others, so I will not be distracted by them. How can I do that? Making the context menu as simple as possible?

Firefox 78 was installed last night. As of now I cannot get the address bar to work. When I type a URL and hit return nothing happens nor does clicking on the arrow do anything. Please let me know how to resolve this issue.

Why is Firefox 78 writing to disk constantly? Even when the browser is idle, the hard drive light on my computer blinks non-stop, and I can hear the constant noise coming from the hard drive. The problem is with the browser because the Processor Explorer (available from Microsoft) shows Firefox as doing the constant disk activity, and hard drive stops making noise when the browser is closed.

Hello. How can i run multiple instances of firefox at the same time? I read this article https://support.mozilla.org/bm/questions/1155401 but it looks outdated because this doesnt work for.

Just got a new laptop, and when opening FF this white bar appears on the browser above the tabs. How do I get rid of that? If I'm recalling correctly, the minimize, maximize, and close functions are present on the tab bar on my desktop FF browser. Screenshot attached

Hello community, would anyone kindly help me with this issue I'm facing? How do I export Logins and Passwords on Firefox running 78.10.1esr (64-bit) on a Mac. The export funtion is not available here and I know the this option is only available on 79 and after, but I'm using a mid 2012 Mac Pro running 78.10.1esr. Is there any way I could still export the logins?

Thank you kindly.

Thanks,

There is a site I visit which embeds stock charts from tradingview.com

I can view any chart directly at tradingview.com but I can't view them when they are embedded at this site: https://www.edumomo.com/blog/2020/07/09/stock-market-watchlist-for-09-july-2020/

I've tried in private browsing since that eliminates any possible conflict with extensions but it doesnt work either.

I've updated firefox and it doesnt make a difference.

I don't know what else to do, I'd rather not have to switch browsers.

Does anyone have experience with this phenomenon:

When you click on a torrent link on a page opened in Firefox 83 (and above), the first window pops up, but the second one (in which uTorrent would come) is no longer. Nothing happens. Specifically, the entry is C: \ ProgramData \ Microsoft \ Windows \ WER \ ReportArchive \ AppCrash_uTorrent.exe....

If I revert to Firefox 82 or 78.6esr, the error will not occur.

If I choose not to download uTorrent but to download the torrent file, it works fine with all versions of Firefox.
