Firefox Support Forum

First time installing Firefox, I mis-entered email address. Wanted to correct. De-installed program, then re-installed. But I didn't get a clean slate. Firefox knew that I had an account. How to wipe slate clean and start completely fresh?

Microsoft will not let me use Opera without having to reinstall it every time Windows updates. I've been using Opera for 4 years and all my data and bookmarks are there. Firefox does not give the option to import from OPERA!!! "Other browsers" never includes Opera. Help? Anyone know how to import from the browser I've been using for years?

I need to install Firefox NEW on an XP laptop. I need the (newest) old version that will install on the XP downloaded to THIS (Windows 10) computer and "Sneaker-netted" to the XP. Then I presume I will be able to download the NEWEST version that will run under XP and do the upgrade. What I received was indistinguishable from the most current version, when I tried to get 43.0.1. Help?

I received a Firefox notice that an upgrade was available, so I clicked "not now" and triggered the update by Menu > Help > About. Firefox apparently downloaded its update, then asked me to restart Firefox. I did so and got a "ransomware" notice from my antivirus program, saying it fixed the problem (but not how). Trying to run Firefox repeats the notice. Does Firefox now have malware in it?

A Web search turns up nothing. I am posting this question from Google Chrome.

I got the pop-up about FF 78.0.1 so went to https://www.mozilla.org/en-US/firefox/78.0.1/releasenotes/ and clicked on "Download Firefox" (https://www.mozilla.org/firefox/download/thanks/). The download dialogue (image attached) that appeared said that it wanted to download "Firefox 78.0.1esr.dmg". The "esr" in the filename surprised me, as I'm not on any ESR release train. Why is it named that and not "Firefox 78.0.1.dmg", similar to its predecessors?

I have an older PC that I have been using with Win 7 as its OS. It's still there on one of the three HDDs that's in the PC. I have since added a fourth drive, which is a WD Blue SSD which is 560 MB/s big, and has Windows 10 installed and running on it, when I start up this PC.

How do I go about replacing the Microsoft software with Firefox and Thunderbird? The Win 10 software is different than Win 7 so I don't know how to use very well. And the Win 10 instructions don't exactly match up with the Win 10 that is installed on my PC, so if some-body could list some of the steps that are more accurate than what MS has given, I would appreciate it.

I've been using Firefox for years but this morning it stopped working. the little firefox button just kept moving left-right and never found the page. Eventually I gave up and uninstalled firefox but when I tried to reinstall it, it states that firefox was previously installed and allows me to reinstall. when I do that it always gives an error message that it was unsuccessful.

I should have mentioned that the uneducated answer provided could not even be replied to. A good way for the uneducated robot to hide, you get one try and that’s it. Then as I said they moved on to something easy and that does not require any brain power. Mozilla might be around for a while longer, however if this is the way they want to treat clients they may not last too long.

I keep trying to download some music off of YouTube through a ytmp3 website that I've used before. But it keeps popping this code up on the screen when I hit download and it doesn't work. Any idea what it means? Thank you

Dear Colleague,

  I am on a Surface Pro 3 running Windows 10 64-bit.     I have been running Firefox for 15 years without a problem. So,  I saw that there was an upgrade to Firefox, and I downloaded it and started installing.    I have completed this process many times in the past.

  When I started running the upgrade, I received the following error,  XUI Runner window that says  "Error Platform version '78.0.2' is not compatible with minVersion>=78.0.1 maxVersion <=78.0.1.  I checked the wiki and the bug list but did not see any bugs.    

  I have not uninstalled and reinstalled yet because I do not want to lose my bookmarks, history, etc. if I can help it.  

  Any help would be appreciated.

Thank you Marj

Hi,

I accidently opened a sensitive file using firefox browser. I reinstalled windows but is there a chance of the file being seen still on the internet? If so, is there anything else I can do?

Thank you guys in advance! I'm kinda worried :(

I just updated to Firefox 78.0.2 on my MacBook Air running MacOS 10.5.6. Firefox starts and opens all my windows as normal, but the page rendering is completely wrong. All pages are affected- yahoo.com, duckduckgo.com, I get plaintext HTML instead of any graphics working. Anyone else have this issue?

The Firefox Installer is WAY too simple for my needs. How? There isn't any "Custom Installation" or Advanced" option. When you open the installer, it just installs Firefox. What I want is something to let me choose where to install Firefox. Anyone know how I can do this? I really like firefox, but the installer is WAYYY too simple, please make an advanced options menu, and tell my WHY you made the installer so SIMPLE. How can we change if it creates a start menu folder, or desktop icon? We cant! Please make the installer more advanced, can someone PLEASE tell me how to change the installation location?

I replaced the HDD in my iMac, and in the process of copying data and applications back to the new HDD from various backups, my olngtime Firefox profile got lost. I have now retrieved it from what I think is the last computer backup. I can't quite achieve getting my new version of FF (78.0.2) on the new HDD to recognize and use the longtime profile. I really miss my bookmarks and logins/passwords. (No, I didn't have Firefox Sync set before this.) Any suggestions greatly appreciated.
