Since today (6/10/2020) I can't run Firefox on Windows 10. Windows says it can't find the route to access, but even if I go to the path and double-click the .exe file, it still says it can't find it. I'm using Windows 10 in spanish, so there's some sort of alias for C:\Program Files\, but it should still work when executing the .exe directly. I've tried reinstalling, uninstalling and reinstalling and uninstalling, deleting my profiles and reinstalling, all to no avail.

I used Firefox and then shut my laptop down. I turned my laptop on after a few hours and received the following error message:

"Windows cannot find 'C:\Program Files\Mozilla Firefox\firefox.exe'. Make sure you typed the name correctly and then try again."

As advised in an earlier post, I ran Malwarebytes and re-installed Firefox. But I'm still getting the same message.

Thank you in advance.

After a chat session with Acronis tech support two days ago, I keep getting unpredictable appearances in Firefox of the opening chat window with "Welcome to Kernel Data Recovery" at the top, including the Acronis rep by both name and picture asking if he can help. So far no response from Acronis. This belated and repeating reappearance of the opening chat window has a time stamp that is current, not one from the preceding day or two when the chat took place. I found a normal looking website for a firm called Kernel Data Recovery, but no phone or chat lines open to them right now. But they did have their sales pitch for agent employee software, so the Acronis chat was likely the cause, but in a way that affects only the browser I was on, Firefox. I opened Edge, and the bogus chat window did not appear. There are not, nor ever have been, any Kernel Data Recovery programs on my PC. And I have no plugins or extensions that could be relevant. Have others experienced this, and could any Firefox steps other than reset (which I recently did for other reasons} be relevant? Firefox is fully updated to 76.0.

I'm using firefox developers edition, and after one of the updates (unsure which one) it does not restarted after updating. After I click on Firefox icon I can see two firefox processes in task manager, but after some time they just quit, without showing any window or even error message. I tried to enter safe mode by pressing "shift" while starting firefox - no result, processes quit before even showing dialog about entering safe mode. I tried to uninstall & install firefox back - still the same result. I removed profiles in "cd %APPDATA%\Mozilla\Firefox\Profiles\" - still the same. There are two records in windows logs upon each start attempt:

I don't even have idea where to start looking for the actual reason.

I turned on Firefox this morning (after a Microsoft update/shut down last night). Heading to my usual pages where my logins/passwords come up automatically, I discovered the boxes were empty - they are usually filled by autofill; these are login pages to my blog, Amazon, eBay etc. I had also been logged out of my Firefox account, so I logged back in (I had remembered that password, luckily) Checking Options/security - show saved logins, I found absolutely no list of saved logins at all. (Horror!) I synced Firefox - still no list of saved logins Where have they gone and how do I get them back?

Hoping someone can help 'cos it's about five years' worth of saved logins.

I recently re-installed Kaspersky on my computer and now Firefox won't open, it was working fine before, there's no error message or anything. I've already been through the articles and nothing has helped, nothing related to firefox will open and uninstalling to re-install has proven to be nothing but a waste of time, does anyone have any suggestions I cannot keep using someone else's computer because of this

Please share some advise on this.

I'm running into some problems with accessing Hotmail as for some reason it will insist on adding a OWA like so https://outlook.live.com/owa/ and I'm being blocked from accessing Microsoft support at as Firefox Claims that Microsoft support at https://support.microsoft.com/ hasn't configured their website correctly which I find hard to believe. Can this be switched off or bypassed as I need to know what's going on with the Hotmail account?

I do have a question. I keep getting a pop about adding a Norton add on to Firefox. I can not find any information on the topic.

I have Norton 22.16.3.21 installed on my PC. I assume it is Noron asking me to add an addon. Has Firefox approved it and how would I find it.

Firefox just did an automatic update to version 65.0 (Firefox Quantum, 32 bit) and ALL of my websites are blocked with the message, "Your connection is not secure".

This is what I get back when I try to access Google: "The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.


Even your own website is stopped with this message: "The owner of qsurvey.mozilla.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

...and Firefox will NOT allow me to bypass this warning, making the browser useless. I'm using Chrome to send you this message.

Chugging along just fine as usual, in the early part of today(using Firefox several times). With Firefox closed, I went to open it and it took ages to open fully. When it did open, the familiar toolbars were there, including my Bookmarks toolbar. The Bookmarks toolbar is showing the icons of sites that I have put there, and it is showing my self-created folders on it (containing various website shortcuts etc). The only difference is that the folders are grey instead of yellow. However, nothing is actually HAPPENING. No matter what I click on, I am not reaching any website whatsoever. I cannot actually go anywhere at all with Firefox. My internet connection is working just fine. I can open email software and I can open (and use) Internet Explorer. Why has my Firefox just stopped functioning on my Windows 7 PC? It is Firefox Quantum ESR 60.2.0esr. I am typing this support request on my Windows 10 laptop where Firefox Quantum 62.0 is working ok!

Hello there. I tried to update Firefox to 58.01, but since updating my antivirus appears to block the firefox.exe.

I uninstalled Firefox completely, then tried to reinstall it but again my antivirus blocked it before I could open firefox.exe

I reinstalled Firefox again, this time disabling my antivirus and Firefox.exe appeared to work again, I was browsing and redownloading my addons. Once the antivirus enabled itself again after 10 minutes, the same problem happened. Firefox shortcuts couldn't find the Firefox.exe, and in the main Mozilla folder, firefox.exe had become firefox.exe.sig

When trying to uninstall it after this happens, I can't uninstall it through normal procedures unless I rename firefox.exe.sig to firefox.exe (which is also unable to run, says it isn't the proper version when it is)

Would appreciate some help here, thank you
