I can't find anything about a compromised Firefox update while using the browser when you go to help and let the browser update itself. It seems you've been hacked because I can't otherwise explain the firefox background update 308046BoAF4A39CB, which is been detected by my systems. I obviously have more information about this if you like, but I see nowhere how to report this properly. This is the first time this has happened to me, at least as far as I know and so far I've only detected the Tr.Gen threat on my Windows computers. I would like an adequate response from Mozilla on how this could happen and what the repercussions are plus how to avoid this in the future. I've been using the Firefox browser on all my systems with various operating systems and would prefer to keep using it, but not if your own updating process is comprimised. I also think it's idiotic that I can't upload a bigger screenshot than 1024 kb because my very relevant picture is 3084 kb in size.

Sincerely,

After update to 115.2.1, FF crashes at startup for one User, but not the other. FF Safe Mode also crashes (SHIFT key). I tried running the 115.2.1 install on the problem User, but it also crashes right after completion. The second user is handicapped, so I have yet to try to uninstall/reinstall because FF runs on her User and I hate to screw things up so that she is locked out.

• • • JUST NOTED - Chrome also crashes with same NTDLL error (same DLL version number). Did the FF update do something with the NTDLL file?

I have been instructed by BCBSIL.com to use GoogleChrome as my browser. Their website is no longer compatible with Firefox. Is there an update that Firefox can do so I don't have to change my browser to Google Chrome? It seems BCBSIL is saying only Google Chrome users can access their site now. BCBSIL is trying to direct what browser I use, isn't this illegal?

I do not have any mobile device to sync with Firefox. HOWEVER, I would like to sync with Outlook.com from Microsoft. Centurylink my ISP provider was off-line for quite a while so they could create a better email program and when they finally came back online, last week, there were a list of things in computer language that I am supposed to do but do not understand. Like you, whenever I want to ask a question I have to send it via email then the response is the same thing listed in their instructions, NO HELP at all. Now, on a daily basis, I am receiving emails from Microsoft Outlook stating "Please update your credentials for the account Rhonda89@q.com." "It looks like we don't have permission to get email for Rhonda89@q.com."

The daily emails from Microsoft Outlook started on October 24, 2022, about the time Centurylink Email came back on line, I think. They did not send any messages advising us of this. I happened to find the information when I looked for it online.

I am still attempting to reach someone at Centurylink for help...lol

In the meantime, is there anything you can do to assist in this endeavour.

Thank you, Rhonda Caywood

Does anyone out there know of a replacement for the Tab Groups replacement app? I have not updated Firefox past the v.55 only because I don't think it would work w/ any newer versions. I have found this to be the very best app I have ever used as I need to do a lot of research online and need something that will show all the windows and tabs on one page so I can easily go back and forth to a particular group quickly. Without this, I would have to spend hours finding the info and would only have one window in which to work. Ideally, a replacement would be able to use all the window/tab info I now have. Is there some way I could use this in some sort of legacy mode? I have several legacy apps, but can't readily recall how to do so. I think I tried this w/ the Tab Groups app and it didn't work, but am not certain. Suggestions much appreciated! Thanks, Wolfgang

Since sometime in August 2021, I suspect after an update, occasionally when I launch Firefox it reports that it was unable to restore a previous session. I do not have the option to open previous sessions selected. On other occasions it starts properly with a blank page as it is configured to do.

Am I missing a setting?

It is not a major problem, I can simply enter a URL or search string in the address bar and it works properly for the rest of the session.

It is happening both on my Windows 8.1 Pro and Windows 10 Pro PCs running the 64-bit version of Firefox.

Any suggestions will be appreciated. Thank you.

I recently had to restore my computer. Doing that I have to get the new firefox which I now have version 102. Updates disabled instantly. I was on version 88. On version 88 this feature was not on it and version 102 now has this feature and I do not like it.

The feature I am talking about is if you open the downloads panel and view the downloads list and right click on one of the downloaded files in list there is now an option to Delete. I accidentlly hit this and thought it was just deleting it from downloads panel. Nope it deletes it from computer permanently, not even to recycle bin. Click Delete its gone for good until download it again.

And this delete option is right above the option remove from history, which I use a lot.

So I want to know how to disable this delete option? Thanks

Crashes freeze ups Tired of them all day every day. Cache fills up and computer shuts down. 24 Firefox processes ,,, 37 Firefox processes and every one of them is storing history and cookies till the system stops.. Performance section? Worthless. Does not matter what is checked or unchecked,, and NEVER has there appeared a box to choose a limit of 6 or 8 processes.. WTF

I cannot stay Signed In on Zoom's website (and I used to be able to). When I hover over the Information icon, I see a message that I have to enable Functional Cookies (see attached). I have cleared my cache and explicitly allowed Zoom, but no luck. I don't have this problem in other browsers.

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?

Hey gang! For some reason firefox will not do anything at all unless I run it in windows 8 compatibility mode. I'm on windows 10. If I open the app it won't search anything, show any webpages, etc - but the search bar still works, it'll show me suggested sites and what have you. I can also access the settings page. Aside from that, zilch. I've done a full fresh install and it didn't fix anything. Has anybody had this before? Thanks!

As I translated Japanese in a translation site, an incomprehensible sentence is sorry

It crashed with update and a troubleshooting mode of Firefox to have already performed that firefox crashed at the time of start and did not open out. Leading you goes uninstallation and down of firefox, when downloaded it, copy information from Old Firefox Data, and stick it on a profile folder in other troubleshooting information from a help, and when restore a former session, after all crash, and do not start. Sometimes start, but become the screen which cannot operate, and nothing reacts, please help me

I put the crash report number bp-add5d98d-377d-47b5-b0bd-bf6f20220715 2022/07/16 2:54

Firefox has been updated on my PC at least 100 times. It ALWAYS brings up the screen asking me to verify if thiis program can make changes to my computer, Why? Is v 102.1 the latest? I don't know I see other comments about other versions.

And so many more issues I am about to pull every last hair out of my head. I don't even know how your Bookmarks work, nothing like I've ever seen. And, why does Firefox Browser open in different pages, sometimes. I'll have 2 rows or 3 rows of add-ons. Sometimes the font is so tiny I cannot read it, other times it's just fine.

I know what you are going to do. You'll give me some instructions with words that mean nothing to me. Then you'll provide articles I can read, and they mean nothing to me either. I AM NOT an IT person. I just want to turn on my computer and have it work properly JUST ONCE! Wouldn't that be great, then maybe twice in a row!

I thoiught i would be happy with Firefox, but I'm not. Just like I'm not happy with Windows platforms from 7 onward. Instead of making things easier for the everyday user all you do is make things more confusing and complex. I read some of the questions on this website and I don't even know what they're talking about.

I just want Firefox to WORK

I cannot login to an important account on a secured connection site. The last time I logged-in successfully was in late May 2022. Later attempts, starting in July, all failed. I then proceeded to trouble shoot by clearing the History’s cookies, cache, Browsing and downloaded history, followed by deleting Site cookies and Site data. I ensured JavaScript, Cookies and third Party Cookies were enabled. The above steps did not fix the problem. I further checked that the CPU time & Zone was correct and I ran a Norton Security full system drive scan. I also Refreshed Firefox and reinstalled Firefox (I did not clear any Firefox related App Data profiles in Windows. Using the Edge Browser did not help. The Internet security options TLS 1.1 to TLS 1.3 boxes were all selected. There were no errors reported when accessing the site. The above steps did not fix the problem. To further investigate the problem, I clicked on the site lock icon next to the address field which showed the correct site information followed by another lock icon and the clause that the “Connection is secure. I then clicked on the adjacent > arrow, which opened a new dialog box displaying another lock icon followed by “You are securely connected to this site” and “Verified by: “Sample Ca2” certificate. I then clicked on the “More info” to open the “Page Info window” (Note: you can use the Firefox Browser Menu/Tools/Page info for the same results. At the top of the Page info window it displays the following four tabs: General, Media, Permission and the Security tabs. Clicking on the Security tab it displays the “View Certificate bar” amongst other things like Password etc., to view the site Certificate, which, in my case, was valid until 17 March 2023 23. 59. 59 GMT. Everything looked ok to me. I am using a desktop PC and the latest Firefox Version (103.0.2) and Windows 10 Home(x64) Version 21H2 (OS Build 1944.1899). I then called the site personnel and explained my problem of login-in. They told me that there were no problems with the account. They suggested I try to connect to the account using

a cell phone, which I did, and I had no problem connecting to the Account.

I deeply appreciate receiving anyone’s assistance. Thank you.

Created - Boomer With A View September 19, 2013 there are 2 Facebook accounts one is my original account the other is fraudulent and I can't recover my account or my blog account Boomer With A View. I just don't know where to go for help. No one ever helps me to get my account , friends, groups, messengers back. Please help me or tell me where to go to get help. FB does NOT help although there are 2 accounts with the same name. E.F. Coleman, Thank you.

Firefox is unable to send the request at the startup, meaning it's just keep showing loading... and then opens the webpage after a couple of minutes. For example, if I open instagram.com: At the bottom it says, "sending request to www.instagram.com" and it stucks on that for some time as I'm not able to click anywhere in the webpage. And sometimes, it says, "transferring data from www.instagram.com" PC and the internet connection is fine. What could be the issue?
