Diễn đàn hỗ trợ Firefox

Firefox has been installed and working on my pc computer for several years. Today the browser will not open. The only program file shown on install or uninstall is firefox.exe.

When I click on the start icon or try to open it from programs I get an error message. It says firefox.exe-bad image.

error status- 0xc000012f . Not designed to run on windows or it contains an error.

The Firefox Browser on my computer contains a lot of information. The user name is dltpm3@aol.com

How can I restore it? Maybe with MS Edge?

Thanks for suggestions.

How do I erase the history on my desktop bc Firefox has been threatened by malware? I have Apple IOS desktop & I called Apple. They helped me close down Firefox on computer. MY FEAR IS that I cannot open Firefox again until I delete that history on my desktop. I am using my iPhone to continue. Please advise how to continue: qatarkat@yahoocom Wednesday night

Hi, Scrolling when content is loading on Windows 11 results in jerky scrolling. This doesn't happen in Edge, Chrome, Brave. Content in these browsers appears to render faster and even when it doesn't, scrolling is not affected. This still occurs when all extensions have been disabled.

Does anyone know why this might be? Thanks

Good evening I sownloaded firefox and the download extension I am not seeing the tool bar what do I need to do have os windows 10 thank you my email adress is dharvey65@yahoo.com thank you

Since 2 or 3 days it's impossible to open websites. Each time I try to open a website (saved website) I receive the error message "PR_END_OF_FILE_ERROR", due to a security problem. According to Firefox the website (page) can not be opened because the authenticity can not be verified. It is a very strange situation, because this problem came out of the blue. The websites I'm trying to open, are saved websites without security problems so far. Moreover this strange situation is only occurring on my "desktop pc with Windows 10" and does not occur on my "laptop with Windows 11"! More important info: the problem is occurring with an ethernet connection both with a WiFi connection. My laptop is always connected with a WiFi connection. Both devices do not use VPN. On both devices is running Bitdefender (with exactly the same options), CCleaner/Kamo (of CCleaner, with exactly the same options). My service provider is Ziggo Netherlands. Consulting Internet, I tried to fix this problem by applying a lot of adviced changes into a lot of options. All without any success. One of the advices I did not try, is turning off the virus scanner Bitdefender, because I do not know how to turn off and how to again on. I did turn off Bitdefender firewall, without success. Fyi: I always use Firefox and I never use Chrome or any other browser. However I checked the situation with Chrome and to my surprise, the same website connection problems did occur! Please advise how to resolve this problem. Thanks in advance. Best regards, Peter

"Manage Bookmarks" [I left the misspelling in the subject line because I'm trying to clue into the conversation when I asked this question before on June 17th] no longer functions smoothly if left open longer than a minute. I will add a bookmark to a folder the first time, but then will no appear to repeat the effort with adding another to the same or another folder. Re 'jscher2000's answer to my question, switching to another folder and back offers no relief from this but you are correct in that the issue is the page does not refresh to show added content after the first (or maybe second) time, if left idle a few moments. Closing out and reopening 'Mange Bookmarks' and navigating to the appropriate folder (or subfolder) then becomes necessary for it to display that in fact it had added the bookmark. Tiresome. Is there any way to increase the amount of memory allotted by my computer or Mozilla to this function, to regain the functionality I once took for granted?

Re 'cor-el' , where is the 'places database'? Re how many, hundreds? See 2 screen shots; alphabetical, partial list of single entry under 'e' 'Evironment'; maybe a thousand. I have not tried restarting firefox in troubleshoot mode (latley), but I think I already tried that some time ago and it did not help.

Since 128.0 was installed outlook.office.com/mail has stopped working. (Windows 11)

My mail account has numerous shared groups. However these now fail to load with a messgae "Cannot load folders for "xxxxxxxxx" Decoding failed.

Additionally, while I can see new mails in the list (under focused and Other), the previews are all blank.

I do not get this error in Edge or Chrome in Windows.

Both my wife and I are unable to get into e-mail accounts. Something changed We have tried the passwords and sometime it works but usually it doesn't. Is there anyone we can talk us thru resetting our accounts We have been susing the program for years with no trouble. How can I make it simple again?

I have an email at currently att.net and have not been able to get into it for 2 days now.

The message is that I should open on a new page. I do and the message is then "something went wrong" and I try again and the same message comes even when opening on a new page.

Need help in opening my email at currently att.net or currently att yahoo.net.

Thank you for your help in advance and look forward to hearing from you soon in this matter.

Thank You, Estella Mills

If I click on a bookmark before my internet connection is established, I get page not found. Natural.

But if the connection establishes while on the error notice, the same bookmark gets the same unfound page. Refresh doesn't refresh. I have to go to another site or burn and start all over.

Same on Samsung Galaxy A34 and New Linux HP notebook.

I attempted to sign into my bank account and I cannot do so. I click on the LOGIN sign and nothing happens. I attempted to sign in with Microsoft Edge and am able to sign into the account. Why am I not able to sign in with FireFox/Mozilla?

Thanks for your assistance.

After one of the latest Firefox updates I am no longer able to login to my aliexpress.com account (while with other browsers - like Opera or Edge - it works without any problems). Trying to login via main page: Login windows opens and after entering correct input data and click on "log on" the login window disappears and the main page opens again - but nothing else happens. Trying to login via "My orders": Login windows opens and after entering correct input data and click on "log on" the login window disappears for a moment and then opens again, ready to input login data - but nothing else happens. How can I solve that problem?
