The last Firefox updates have suddenly created havoc. None, absolutely none of the websites that I frequently visit will have my login information saved even though when I view logins in the settings mode, they are all listed there with the correct passwords. I am not technical and would sincerely appreciate a tutorial of some kind as to how to correct this egregious oversite on behalf of the Mozilla team.

SHORT SUMMARY:

A few specific direct downloads from a third-party server successfully finish in Regular browsing mode but fail half-way in Incognito mode. This is reproducable on numerous tries and persists between Firefox restarts, system reboots, and ISP changes. This difference between Regular and Incognito remains even when the requests that the browser sends are fully word-for-word identical, down to the DNT=1 in the request. There are no issues with downloads in Google Chrome on the same machine, and similarly no issues in Incognito mode in an old ESR Firefox (v52) on a really old laptop with WinXP. This problem ONLY appears in Firefox 92. ========================================

FULL DETAILS:

I'm using the latest public release of Firefox, 92.0.1, on Windows 8. I have a habit of using Incognito mode most of the time, and I found out that certain downloads fail in Incognito tabs - but succeed in Regular tabs. A few examples:

http://down.360safe.com/cse/360cse_official.exe http://down.360safe.com/cse/360cse_9.5.0.122.exe http://down.360safe.com/cse/360cse_9.5.0.114.exe http://down.360safe.com/cse/360cse_9.0.1.162.exe

They are direct links to the .exe setups of various versions of an obscure browser called 360 Extreme Browser, recommended for use with WinXP on obsolete hardware since it's supposedly very lightweight. You can run them through VirusTotal if you want. The first link always points to the latest release, the other links are specific releases.

When I open any of them, I am first presented with the regular download dialog box, while Firefox automatically starts downloading the file to %TEMP% in the background, without waiting for my decision (as it always does):

https://i.imgur.com/0D6pH4Z.png

... then, a couple seconds later, I'm presented with the "source file could not be read" error.

https://i.imgur.com/3f6StGQ.png

When I click OK, the first dialog box also disappears, and there is no trace of the (failed) download left in the download widget in the top right.

Alternatively, I can try to be very fast, and as soon as the first dialog box appears, I can quickly click "Save File" and press Enter in the folder selection window that appears. That way, I can confirm the download before it gets a chance to fail. But it fails anyway, except this time I can see the incomplete file in my destination folder, and the failed download in the list of downloads in the top right corner of Firefox. This download fails about 5-15 MBs into the file - it's different between different attempts.

It is my understanding that the "nature" or "mechanism" of the fail is the same, but if it happens while it's downloading to %TEMP% and I haven't selected the folder yet, then I'm presented with an explicit error message and there is no trace of it in the download history, and if it happens when I've already selected the folder, then there is no explicit error message and the failed download is displayed in the download history.

In the latter case, I can then press "Retry download" in the download history. Then, the download will successfully restart (not from zero, but from the percentage that it failed at) and will successfully complete. But the FIRST try, initiated by the tab ("by the page"?) and not by the "download history" widget in the corner, ALWAYS fails at some point between 5-15 MBs.

========================================

INVESTIGATION AND LOGS AND LOTS OF TECHNICAL DETAILS

So you might say, that third-party server is acting weird and is probably misconfigured. But:

  • This download ALWAYS SUCCEEDS without any problems in Regular (not Incognito) tabs. It ALWAYS FAILS in Incognito.
  • This download ALWAYS SUCCEEDS in Google Chrome that I have on this same machine, both in Regular and in Incognito.
  • This download ALWAYS SUCCEEDS in Firefox 52.9 ESR on a really obsolete laptop with WinXP that I have, connected to the same network(s), both in Regular and in Incognito.

To sum up, this fails VERY SPECIFICALLY in Incognito mode in Firefox 92 (current modern version) and NOWHERE ELSE.

All download attempts that are successful (non-Incognito FF 92, Google Chrome, FF 52.9 ESR...) result in a downloaded file with the same correct size and checksum. The download that is successfully RESTARTED after failing in Incognito (read details above) also results in a file with the same size and checksum.

I am not aware of any software on this machine that would be interrupting the download, such as antivirus. In any case, it's interrupted when it reaches a different random size on each different attempt, and it only affects Incognito Firefox and nothing else - not Regular tabs of FF and not Chrome. I have also tried two different ISPs - one that provides me with Ethernet at my place, and my mobile phone ISP. Same behavior between them. The only third-party plugin that I have in Firefox is uBlock. I disabled it completely and this didn't change anything.

I've inspected the requests and responses, using Firefox's own dev tools.

REGULAR TAB (not incognito) = SUCCESSFUL DOWNLOAD

https://pastebin.com/xzXXJDEt (so as not to clutter this message with long request listings)

INCOGNITO TAB: FAILED DOWNLOAD

https://pastebin.com/Nq0txZ9P (same reasoning)

The differences are: Incognito mode forces HTTPS, sends Sec-Fetch- entries in the GET request, and also sends DNT = 1. Everything else is the same.

I then went to Firefox settings and enabled sending DNT *all the time*, even in Regular (non-incognito) tabs. I also tried to download explicitly from the https:// URL in Regular (non-incognito) mode, just like Incognito mode forces https. This resulted in a request that is sent from a Regular tab but is 100% identical to the request sent from Incognito mode. Read below:

https://pastebin.com/0QCpKqBZ (same reasoning for hosting on Pastebin)

You can check that this request from a Regular (non-incognito) tab is now word-for-word identical to the request from an Incognito tab. Yet, the download from Incognito STILL fails at ~10 MBs into the file, and the download from Regular STILL succeeds. I fail to see any difference between the requests, whatsoever.

In the Cookies tab, there are "No cookies for this request" for both Regular and Incognito downloads. The Security tab looks 100% identical for Regular and Incognito downloads, and looks like this: https://i.imgur.com/SAhzquW.png (idk how to copy this in plaintext form).

In another online discussion elsewhere while I was troubleshooting this, I was advised to see if network.dns.echconfig.enabled was set to TRUE and to try setting it to FALSE. Not sure what this would change, but I went to check and found that it was already FALSE.

Also, in that discussion elsewhere, I had one more user running Firefox on Windows 10 (according to his publicly displayed user agent) confirm this. But I don't know how to reach him to ask for extensive troubleshooting like mine.

========================================

FINAL SUMMARY:

  • Some specific downloads fail halfway in Incognito Mode in latest Firefox
  • There are no issues in Regular (non-incognito) mode, or in Google Chrome on this same machine, or in obsolete Firefox 52 on another machine
  • This persists across Firefox restarts, reboots, ISP changes
  • This difference between Regular and Incognito modes persists even when you change settings so that the sent GET requests are 100% word-for-word identical

Help me troubleshoot this further? Even if this is caused by that third-party server acting up (for whatever reason), how does it tell between my Regular firefox tab and my Incognito firefox tab when the sent requests are the same? And even if this is caused by something else on my machine or in my network, then the same question applies, how can this "something" tell between my Regular and Incognito tabs?

Yesterday I started Firefox and got a question on Syncing; I think I answered "NO". All of a sudden Firefox disappeared, and I got "Bing-Firefox" browser. All my bookmarks were gone, and all the browser information presented me with "Microsoft" stuff. The Firefox icon is still on my desktop, but when I choose it the only thing I get is "Bing Shopping", "One Drive", etc. I don't want anything to do with Microsoft, or "Bing"; what happened? How do I get back to pure Mozilla Firefox?

Thank you, Peter

If what im reading NOW is true, they are really lost. You should be spelling this out FAR MORE STRONGLY and tell people that they CANNOT reset. Its basically erased ten tears of my data and im utterly lost- i had impossible to recover links and passwords in there and it all appears gone. resetting and wiping is basically starting again. id have tried a bunch more to recover the password had i realized what was gonna happen. Im am so upset. I will now take this opportunity to change browsers as im starting from fresh so ive nothing to lose and for you to take such an enormous step without a strong enough warning is extremely poor.

The new changes don't make sense at all ... They basically reduced the contrast and/or increased the brightness in the toolbar. Like other humans, I rely on contrast to see where one thing ends and another thing starts.

There are similar questions - https://support.mozilla.org/en-US/questions/1302582 - with no answers that get archived. Why would they be archived if there are no answers? Will this just be another one?

I'm loading a local file, not via a web server. In Developer Tools / Network tab I have Disable Cache checked. When I change the file, FF does not load the new content - on Cmd-R, reload button, reload from the Network tab. Browsers used to have a handy keyboard shortcut to force a full page reload, but now that is gone. I even tried clearing all storage for the page.

It is very tedious to close the tab, open a new tab, open Developer Tools, and enter the local file URL once again for every change! Why can't there be a simple way to force this? I even tried about:config browser.cache.check_doc_frequency set to 1. Why do none of these approaches work any longer?

Does FF have any role in logging me out of a website due to some time limit? I complained to a site that I lost a lot of typing because it had silently logged me out. I was told by one of their CS people "The issue is actually with your browser. Browsers have a security feature that automatically logs you out of secure areas if you are not moving around, which unfortunately excludes typing. The idea is if you were logged into your online bank account and left your computer, someone else could not sit down 5 minutes later and start doing things in your account. This feature is for any secured area, any area you have to login to access. It is not something we do or can prevent. I am very sorry for the inconvenience."

IMHO this is BS, but please tell me if FF could have terminated my session somehow. Thanks. GD
