Firefox Support Forum

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

Some are this instead: Filename: umppc14105.dll Version: 6.27.14105.0 Debug Identifier: CE458B39D37A4C65A60024BBACED6EB31 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

Hi there, I'm having trouble opening firefox that suddenly didn't open after I've used it as usual. When I've closed it, I've put the macbook on sleep mode and then reopen it after 10 minutes and tried to open firefox as always. It didn't. I'm trying to figure it out and I've followed all the possible paths on Mozzilla's support and others blogs, but none of them worked out. I've tried also to uninstall and re install firefox from scratch, but nothing happens: I still get the message. At this point I don't care if I need a fresh start, I have a bookmark's backups so, how can I really uninstall Firefox and install it from the beginning? Is there a hidden folder I'm missing? Thank you in advance

MacBookPro8,2 - macOS 10.11.6 El capitan

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.

This the second time I am entering this problem -- the first time Firefox refused to let me return to this site.

First, I am running Firefox on Ubuntu, but Ubuntu is not relevant because the same issue occurs in Windows.

Whenever I access a file, for example, one at https://species.wikimedia.org/wiki/Chioneosoma, its color (which is programmable) changes from a light bluish green to a deeper violet. Where is this color-difference stored? I have thousands of WikiSpecies files I have accessed, and they all show the violet "accessed" color if I ever have opened the file to read its contents. The problem is that when Ubuntu has to be reinstalled, I can add references to all my files, but the color-changes seem to be lost. This is a serious issue, because I currently have over 50,000 files referenced (and saved in my directory file:///home/jwill/Documents/WikiSpecies/Animalia_Plantae_8) and am still adding to them!

I think the storage location must be somewhere in one or more of the following files ('_' replaced '/'):

   _home_jwill_.mozilla
   _home_jwill_.cache_mozilla_firefox 
   _home_jwill_.cache_MM_firefox
   _usr_lib_firefox

Can you please tell me where the list of accessed files is stored? Whenever I enter a referenced directory, to access it, the color changes; so, Firefox must be able to store a reference to each new referenced directory name.

The browser's interface language, including links, menus, ads etc., changes without warning into languages I don't know. Sometimes the whole screen is in one language, at other times, several languages are on the same page. Even after re-selecting the preferred language, the problem persists.

I just used pacman to update to the latest Firefox, but the tab crashed each time I open a new web page ( I can open settings, about:xxx and etc... ). I tried Troubleshoot Firefox crashes and it did not crash in troubleshoot mode. Then I tried extensions, themes and hardware acceleration issues to solve common Firefox problems https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems but non of these options solved the problem. I disabled all extensions, themes and hardware acceleration, and it reported the same error.

For real — it's terrifying how much we don’t know about Facebook. The social media giant has almost 3 billion users (and tracks many more), but this year we've seen yet again how the secretive way it operates is dangerous for all of us.

By keeping us in the dark about how it combats misinformation, who's paying for ads and how social media affects our mental health, Facebook actively stops us seeing when it’s causing harm.

But here’s the thing: we're not going to just accept it.

It's true — Facebook's secrecy puts us all at risk. To keep us safe, we urgently need it to be open and accountable. Chip in now to join the fight, it takes 1 minute:

• button* Yes, I’ll chip in now

I try to access my bank website and when I log in the tab says "Something went wrong" and the page tells me Sorry, we couldn't complete your request Sign in to online banking or our mobile banking app to continue. This started on April 1, 2021 Running Firefox v87.0 (64) on Win 10. All apps are current. Tried resetting Firefox, and clearing cache which didn't work. I can sign-in using Edge. Thanks

I usually have Firefox open for 8 hours a day (open Firefox in the morning and close it in the afternoon). About once a week I'll notice that at some point during the day Firefox will just stop loading new websites. Existing sites will continue to function, and requests to those existing domains work. But new sites, that I didn't already have open, won't load at all; the tab will just sit there, thinking indefinitely (no errors).

When it does this I will try microsoft.com or google.com to check and make sure it isn't just the site, but those won't load either. I'll try it with a Private Window as well to the same effect (private window has no extensions enabled). Chrome/Edge still work fine during this. In order to get Firefox working again, I have to close Firefox and then usually force quit the process instances (or wait a long time for it to reopen on its own). Once reopened everything is back to normal and all sites load as normal.

I think this happens when Firefox loads a new update in the background. I've noticed on more than one occasion this behavior has coincided with a new Firefox version. In fact it just did it again (prompting this post) and when I got Firefox back open again it had a new update tab displayed. So I'm fairly sure it is the background updates causing this.

This behavior has been happening for a very long time. At least 6 months. Across many Firefox updates.

I have a separate Firefox profile that I load using a separate shortcut (with the -P property). When this behavior happens it often impacts both instances of Firefox. Not sure if this bug is related to having multiple profiles or not.

Windows 10 64-bit

I can find no recent documentation on command line options for the Firefox Browser. All of the information on this appears to be out of date or just does not work any more (in the latest version June 2021). Is there any documentation on this anywhere that is correct for the current version of the browser? I am specifically trying to run firefox with command line options on Windows 10 but I do not see that that should make any difference. The only option I can get to work is starting firefox with a specific URL; even then I have to change the browser settings to get that to open a new window; because the browser settings override the command line option -new-window

Can anyone from firefox send me the instructions to get rid of this message. Secure connection failed and Firefox did not connect

Please avoid sending links with tons of info to read because I don't have time to follow.

Many thanks Jorge

I just updated to FF 111.0. After restarting FF comes up but then nothing. After a bit of I got the option to force close it. I tried opening a Private Browser and that worked fine so I figured it was one of my add-ons. However after closing the Private Browser and trying opening normally again it worked just fine. Disable all of my add-ons and for the same issue.

Renamed my AppData/Roaming/Mozilla folder and starting as normal worked fine. What a giant pain in the <bleep> trying to set everything back up.

Performed some more science and noticed this. After setting my Mozilla folder back, starting FF, and looking at the TaskManager, There would be 3 processes, one of those after a bit of time would show in red as Not Responding (or words to that effect). Clicking the window a few times to get the force close dialog again. Trying to open FF again, it opened just fine.

So I'm tempted to blame something in the update that is causing this. Yes, I could just start with a fresh Mozilla folder and reinstall all of my add-ons and blah blah blah, but whose to say that after setting everything back up the way I had it the problem won't come back.

I have thought about rolling back to FF 110.0.1, and suppressing the update check.

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

Recently I was having trouble using Firefox with my web based Outlook email and asked Microsoft for support. In their reply they recommended that I reset Firefox.

I am reluctant to do so as I don't want to lose all my add ons which have accumulated over time as I am not sure about how to get them back if I lose them with a reset.

Is there a way to reset Firefox but keep my add ons etc?

I would appreciate your advice and thank you in anticipation.

Hi, I have tried all day trying to get rid - of SaveFrom.net Helper - no luck. Latest Firefox running on latest Win.10. So frustrating, tried all sorts of tricks and nothing works Cheers,

I recently got all new devices and traded in my previous ones and when trying to login to Firefox Sync, I can sign in successfully but then I’m required to provide the 6-digit code that is sent to my email. I am unable to login to my email because the password in stored in my Firefox Sync saved passwords.

Attempted to reset my email password (Gmail) but I need to enter the last password that I used, which I have no idea since I’ve always used Firefox Sync and all I get from Google is “we are unable to verify this account belongs to you”. So not much traction on gaining access to my email account.

In my mind, I assumed that by utilizing Firefox Sync as a form of a password manager, I wouldn’t be in this situation as long as I knew my Firefox Sync password. I have since learned otherwise. I can sign-in on accounts.firefox.com but of course making any change requires that I put in the code that was sent via email.

I attempted to download Lockwise and again prompted to enter the code sent via email.

So at this point, I’m just wondering if I’m out of luck and although I know my password to my Firefox account that I’ll be unable to regain access to it or my email because I can’t access the 6-digit code being sent to that email.

Any additional support or suggestions are appreciated but I feel like I’m unfortunately at the end of the line here on what else could be done.

I have no screen capture whatsoever - no menu comes up with a right click, no screen capture icon is present to add to the menu. I used to have an add on but that disappeared and is no longer available. From your latest tips letter I think I'm using a different browser entirely! If you can help I'd appreciate it- as I say I used to have it in my browser but no longer. Now I have to screen capture and edit it in an external program- I'm sure you'll agree this is horrific to have to do.

Hello,

since yesterday after closing FF to restart, I encountered a problem. Everytime, when I try to open FF, it says that the profile isn´t available or not accessible.

I tried already to rename in /library/Application Support/Firefox, Profiles.ini -> Profiles.iniOLD and the folder Profiles -> ProfilesOLD.

As well I tried to call the Profile Manager from terminal using the below commands, since FF isn´t open. /Applications/Firefox.app/Contents/MacOS/firefox-bin -P /Applications/Firefox.app/Contents/MacOS/firefox -ProfileManager

No matter, whether I rename the profile.ini or try to call the profile manager. Each time I get the same warning, that the profile isn´t available.

Since I tried every possible solution, which I could find on the help pages, I hope to find help from the community.

best regards Corey

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95
