For 3 days I have been trying to install Firefox. Firefox dowloads and starts installing. I have set Firefox as my default browser and turned off antivirus to not interfere with the install. It appears to install and then gives an error message that the address of the download file is incorrect (see attached JPG). I sometimes get a message about a file being corrupted (roughly one time in each five tries) also shown in the JPG. I have tried clean installs at least a dozen times (delete the programfiles/mozilla node and then do a fresh download. After clicking download have selected both run and save multiple times. I always get the error message about a bad address. Any help would be greatly apprediated. Thanks.

My Fox was working fine. I downloaded a few add-ons and last pass. Shortly after that, I discovered that Fox was not on the taskbar, in the smart window or listed anywhere. So I have to download it every morning if I want to use it. Once downloaded it recognizes me and has all my bookmarks.

I "upgraded" to Catalina from High Sierra and Firefox now crashes and won't reopen because it says I already have another copy open when there is not other copy

Catalina (10.15.3) and Firefox (73.0.1) aren't working together. As soon as I stop actively using Firefox it crashes. If I try to reopen it, I get a message that I can't reopen it because there is a copy in use already. If I try to force quit Firefox it is not in the force quit menu. If I look in Activity Monitor Firefox is not present there either. Thank you.

Hi,

after I received the 'Firefox appears to be slow' message for a couple of times in a row I decided to use the 'clean install' option that it (the browser) offers. I was under the impression that you could choose what to clean and what to keep, but apparently I was wrong. I now have a clean install and all, but everything is reset - back to default.

I do have the old files on my desktop and tried to import them like mentioned here: https://support.mozilla.org/en-US/questions/1212433 But it didn't work at all. And to be honest ... I don't remember all of my passwords, which is what I truly need from my old files.

As above. FF installed the update despite the checked option to NOT install automatically. NO "old firefox" folder was created-anywhere. No other profile is present that has the old data. My adult daughter's grad school laptop. Years of bookmarks, logins and I do not know what all ARE GONE!! I allowed FF to download but NOT INSTALL-since it was not my machine and I wanted to avert any disaster (I, in fact, looked at the options first, to make sure) NOW WHAT?? Is that is a bug?? Why was there no "old FF" created? Why did it install regardless of instructions to the contrary. Is there some other place to look? She does not seem to have any automatic backups for FF profiles.

Hello,

I see this issue happened for other people but I coudnt find the right answer :

I am on Linus and whatever the version I take (latest I tried is 67.0b9), I have an error trying to run it in command line.

$ ./firefox (or with the -headless I tried too)

PCOMGlueLoad error for file /local/vestbin/oxygen-uat/drivers/firefox/libnspr4.so
cannot open shared object file: No such file or directory

Couldn't load XPCOM.

I checked all preriquisites and installed GTK3 but Still have the error.

What could it be ?

Thanks and Regards, Jeremy.

I am using Windows 10. Firefox 44.0 crashed. When I tried to reopen it it said a duplicate was running. I checked the Task Manager, there was no Firefox listed. Then I removed Firefox 44.0 and rebooted my machine and reinstalled Firefox 44.0. It said the same thing but when I clicked to close it, this time it said the profile was missing. I removed FireFox 44.0 and rebooted my machine. I downloaded the latest version from Mozilla's website and tried to install it but it tells me that "For some reason it could not install the latest version" and to try to start it again.

Where are my existing Questions etc from the "Firefox" account linked to this new system? It promised that they would be linked if I used the same email. Nothing is in my Profile - I want my list of previous Questions !!!

Should have send everyone email warning of this. New account creation page should have option to enter existing UserName & be sent an email, so you know what email was being used. Over the years there have been many. Also different emails for "Get Satisfaction" (Is that defunct?) & for sending questions to Developers and AddOn authors...

I used the address that I found searching old email for announcements sent by Firefox/Mozilla, so it SHOULD be the one I used "here."

Usually upgrades are automatic with a progress bar showing completion... I don't ever recall a Firefox Upgrade in the format:

"Firefox would like to make permanent changes to your Hard Drive" [.sic]

I've had some Malware issues lately so I am suspicious of this unfamiliar format.

Thank You for your assistance with this matter...

Where am I to look or expect your response?? Through my Email Address would be just fine.

Regards,

I have firefox quantum v66.0 (64 bit). When I check for updates under help/about an update download begins but then my computer crashes with an APC Index Mismatch stop code. When I log into firefox I get a page offering a down load of firefox quantum which I already have. Sometimes when open firefox I get a dialog box asking permission to update firefox. Clicking yes results in a blue screen crash with the APC index mismatch stop code. My operating system is Windows 10 home 64 bit. I can use firefox if I don't attempt the update but would like to have the latest features. Should I perform the offered download? Is there another solution.\?

I accidentally installed the Firefox Developer Edition to the wrong hard drive, so I tried uninstalling it so I could reinstall it to a different location. However, when I open the installer, it only gives the option to reinstall and installs back to the old location. Is there a way to re-install Firefox to a different location than the previous install?

Hello. I had naively let my computer do an upgrade of Mozilla. Guess what. All data gone. History, bookmarks, add-ons. I didn't have a back-up of bookmarks, well, at least not recent.

How can I get them back? I've spent a lot of time with setting up Firefox so it would be comfortable to me, I've spent my time in it, and now it's all gone and I don't even remember the name of some add-ons I used to use.
