Firefox Support Forum

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.

When I was using version 88.x, Firefox had not crashed for years. Then all of a sudden, Firefox would crash several times a day. I looked and Firefox had updated me to ver 89.0. But I let it ride. Then Firefox about a month ago, Firefox stsrted to crash EVERY DAY. Then one day it crashed EIGHT TIMES IN A ROW and I mean when I hit RESTART, IT WOULD CRASH. I tried to revert to rel 88 but Mozilla WILL NOT ALLOW US TO REVERT BACK TO A PREVIOUS VERSION. When you do, the PROFILE gives you TWO OPTIONS: 'EXIT or CREATE A NEW PROFILE.' Certainly you do not want to CREATE A NEW PROFILE as you will LOSE, your history, add-ons, Bookmarks, EVERYTHING and you see a WHITE Firefox screen with nothing. So I choose EXIT and tried to put up with the CRAPPY ver 89. BUT FIREFOX KEPT CRASHING. TODAY IT CRASHED SIX TIMES IN A ROW......When I checked the VERSION, YOU HAD UPGRADED TO VER 91.0b6 (64-bit) AND IT IS NO BETTER.

WHAT IN THE HECK IS GOING ON. I DO NOT WANT TO LEARN CHROME OR EDGE AS I HAVE USED FIREFOX SINCE VERSION 1.0.

DOES ANYONE KNOW HOW TO GO BACK AND KEEP YOUR OLD PROFILE, FLACKY OR NOT AS THAT IS BETTER THAN 'RESTARTING' FIREFOX ALL THE TIME.

MY VERSION 88 NEVER FAILED.

I tried to read my email today after a few days of not being on my computer. It wasn't working correctly so I shut down the browser to try again. Firefox is no longer on my computer, the shortcut is broken and I can't find it in the list of programs. I tried to reinstall and at the end it said: Hmmm. For some reason, we could not install Firefox. Choose OK to start over." I shut down my computer to try again and get the same result. Help! Is Microsoft blocking Firefox?

I'm currently in my vacation home and I don't have home internet here. I'm connecting through my mobile phone using limited mobile data. and I selected not to download updates because it keeps updating itself like twice in a week and every MB counts in limited data plans especially if it's just 4 GB total for each month.

But now every time I open the firefox it showing download latest update popup like an annoying virus on the top right corner where 3 horizontal lines are located.

I checked the internet and previously this was an option in it's settings. Then this option removed and only hidden behind the about:config . and now it's completely removed from about:config either.

The only reason I switched from chrome to firefox was because google became an absolute dictator lately and all it's changes was to limit down my accessibility. I switched to firefox becuse it doesn't backstab it's users and they give the choice to it's users rather than dictating it like dictators. So did I make a mistake switching to firefox? Is firefox becoming just like chrome now? or is there (hoping so much) and option given us to turn off the notifications as well?

there are no compatible versions of my add ons or extensions and i have lost a boat load of tabs i had saved and i want them back so i want to go back to the previous version of firefox...i now have the new 17.0 and not happy i lost all my info and settings

I have just upgraded to Firefox 17 and found that Norton 360 "Login Assistant" (formally named Identity Safe) no longer works. It does not fill in the username and password fields. It worked very well and did all the right things when I was using Firefox 16. There is probably a quick fix but in the meantime I have had to revert to version 16. Looking forward to the problem being resolved.

Every time I open a Yahoo finance page I get a pop up window from Firefox that reads as follows: "Opening DARTIframe.html" "You have chosen to open: DARTIframe.html which is a: Firefox HTML Document from: http://download.finance.yahoo.com What should Firefox do with this file? etc.

Hello- I am new to Firefox. I have it set to update automatically. I noticed it was updating to the latest version today, so I stayed and watched. I had version 3.5.2 (I am pretty sure) but the latest version it just updated to is version 17. Is this right? I am used to version going in order but from version 3.5.2 to 17? did something go wrong?

i am enrolled in the beta channel but because the notification popups are so quick i someties do not see that a new beta ver is available. i consult filehippo regularly to see what updates are out there but i want to have a way i can find what beta i'm at - Help|About Firefox doesn't get it - how can i find that? looked in registry but haven't found what i want

any idees?

Every time I log out, shut down & restart. It returns Firefox to the default settings that occur after a new install. It keeps the settings if I exit & restart Firefox without shutting down but if I shut down, it forgets everything.

My 64-bit Windows 7 HP SP1 based notebook was under repair for the past couple of months. So, recently when I got it back, I upgraded Firefox manually to the latest version, i.e. 17. However, noticed that both Version 15 and 17 are listed in the Windows Programs list (Add/Remove Programs list). Can I remove / uninstall Version 15 and leave Version 17 alone, or do I need to remove both and reinstall Firefox 17 afresh ? Is this some sort of a bug in the Firefox installation process ?

I am currently using version 14.0.1 I haven't been able to finalize any recent upgrade. After I do the update and restart Firefox I get this message “Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again”. This keeps happening despite having closed Firefox.

For unknown reason Firefox 17.0.1 has stopped downloading pdf's. This was happening before upgrading to 17.0.1, and before upgrading to Mac OS 10.8.3 from 10.7.4. In order to get pdf's printed, I have to copy the links and download them on another browser, such as Safari. On the other hand, browsing with Safari alone won't work because it messes up the various websites' formats, and becomes unreadable. Firefox will also have this problem occasionally, but usually not.

    To overcome the problems I down loaded Chrome and Camino, but they only allow new pages as tabs, instead of fresh windows, so they have just added to the frustration! Since I never had these types of problems before, I can't figure out if it is the browsers, or my OS, but I suspect the latter. Have you had similar reports, and if so, where you able to offer assistance?  Thank you.

I am running Windows 7 64-bit OS, and I currently have version 12 of Firefox installed (updated in May). I am building an OS vs Browser compatibility matrix, so I have been doing a bit of 'Googling' today to see what versions of Firefox are currently being supported. When I opened Firefox to see if I was running the latest version, I received a prompt to update to 14.0.1, yet the latest version is 17. This is causing me some confusion. Also, some websites are suggesting the Firefox 64-bit is not supported in WIndows and others are saying that it is in deed supported. Could someone please either confirm or deny this?

Firefox updated itself to 17.0.1 and the toolbars disappeared. The icons for the Noscript & Fireshot do not appear nor can they be found in the menu system, although they do appear in the Add-ons manager. If they are not compatible, how can I return to the previous version of Firefox?

I updated v17.0 to v17.0.1 Works fine for a day then next day I bring up Firefox and find it again welcoming me to V17.0. I upgrade to 17.0.1. It works fine for a day and then the cycle starts again. This has happened once a day for the last several days. I tried completely uninstalling Firefox and reinstalling. No joy; same cycle continues.
