Firefox Support Forum

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

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.

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

Hello. Im new to the Mozilla Support community

I am running a Japanese Windows XP SP3 on VMWare Workstation 16, i have downloaded a old version of firefox, due to newer versions not working on xp

And heres the issue: Firefox keeps opening tabs randomly which are related to pornographic websites like xxnx, pornhub, evilangel n' etc..

Heres things ive tried, but didnt work: -Install tdsskiller & scan -Scan with Avast Antivirus -Uninstalling Firefox and delete registry entries -Getting IE8 or G**gle Chr*me for Windows XP SP3

Any way to resolve this problem? i can't watch these things!

Hi, I'm running Firefox on Ubuntu 20.04.2 LTS Gnome Version 336.38. For at least one month now Firefox has stopped working. When I start Firefox normaly (or in the tor-browser bundle) the Firefox-Window opens but no page is loaded. No matter what page I navigate to, nothing happens. I can't even open the firefox settings. I updadet from the normal version to 89.0 but still nothing working. Anyone got any ideas?

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

As the title says, I cannot get MP4 files to play in Firefox, which renders several websites unusable. These sites work in Edge just fine, but I cannot get them to work in my preferred browser. Everything is up to date, and I have all the codecs I could ever need installed, as well as the Windows N Media Feature Pack. The browser has been tested several times in troubleshooting mode, and I've even gone as far as running Windows in safe mode with networking to try to isolate the issue. I cannot get it to work at all. This is the 2nd device I've had this issue on, and it's driving me up a wall.

Any help or advice would be greatly appreciated.

Hi,

I'm having a really strange problem.

I'm using Firefox on WIN 11 with my new LG laptop.

When I access a website's drop-down menu, it does not offer me options that I can make a selection.

I know that it's missing the 2 options - because when I try it on other PCs - it works fine. So the behaviour is different (and works) on other computers.

And the stranger thing is; it also does not offer the options when I tried it with Chrome and Edge.

I tried clearing the history and cache - and it still gives the same behaviour.

I called the Tech Support of the website - and they said it's clearly a problem with my specific PC. I would tend to agree with them - because I can access their site without any issues on other PCs.

I can't figure out what's in common amongst the 3 browsers I tried on this LG laptop. The only thing I found in common is this laptop!

Any ideas - any thing I can try next? Really driving me nuts...  :)

I've started having a strange issue with both Firefox for Windows and Android. On some news websites, and sports websites, I can no longer open articles just by clicking on them, but right-clicking works. If this sounds strange - it is!

The issue is exactly as it sounds like. I can hower the mouse over the title of an article and Firefox will recognize that it's a link, showing me the path at the very bottom left of the browser. But when I click it, it simply won't do anything. My mouse works fine before you ask. It's only when I right-click the same article and choose "open in new tab" that the article opens. This is happening on some major sites as well, like the BBC.

At first I thought this was Windows-specific, but I have also had the same issues with my Firefox for Android. And again, long-pressing on the article and selecting open in new tab will open the link, but not normal tapping.

I have restared Firefox in Troubleshooting mode to disable any addons but the problems persist.

Anyone else having the same issue or is there a known solution?

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

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.

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:

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.

Local TV Station Radars and Bing maps will not load anymore. However, the weather channel radar does work. Weird. Running Firefox 90.0.0(64bit) on Win 10. Tried deleting all cookies and cache- no joy. Tried safe mode- no joy. All Radars and Maps work in Edge, but not Firefox. What else can I do?

Thanks!! Jon Abel

I am trying to disable Firefox notifications whenever I take screenshots, and googling for solutions, I found the commonly suggested solution is to uncheck the "Pause notifications until Firefox restarts" box in Permissions:

How to turn off forever the "screenshot" splash notification

"shot Copied" window

This option is not available in my browser version; thus, I'm hoping there's a newer workaround for this.

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
