i've already tried all of the fixes stated here https://support.mozilla.org/en-US/kb/cant-download-or-save-files and i've tried logging out my mozilla account and downloading, i've tried starting firefox in safe mode without any add-ons, i've tried pretty much everything i can think of. no matter what the download fails and a 0kb file is created instead. when i try to download a webpage i get a 0kb html file and a folder containing all the contents of the html file, also i can download images perfectly fine even though it says they fail. i've tried downloading multiple types of files and it's not just webpages, .zip files fail, .exe files fail, everything that isn't a photo fails. the only other thing i can think of is .pdf files do a similar thing to html files, where a 0kb .pdf is created and a .pdf.part file is created the size of the actual pdf. also i've tried downloading using other browsers (excluding chrome, because it crashes my pc on startup) and they've worked perfectly fine, firefox and firefox nightly are the only programs having this issue.

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.

Unable to import saved firefox profile (from windows 7 32-bit, to windows 10 64-bit) - new profile has none of my data

My attempt at transferring profile from an existing machine to a new machine has not produced the intended result, and I need help.

I saved my firefox profile (on a 32-bit windows 7 machine; firefox was fully up to date) without firefox running, in a ZIP file (the letter number combination followed by dot followed by default), then copied the ZIP file to the new machine (windows 10 64-bit), unzipped it (so I had the same file name as from the old machine), then copied this folder into position at

C:\users\user\appdata\roaming\mozilla\firefox\profiles

I then started firefox on the new machine, went to about:profiles, created new profile, selected the folder (which was present at this step), then completed the procedure and started a new firefox with the new profile (the option given in about:profiles).

The new instance of firefox has none of my data (several thousand bookmarks, passwords, etc.); instead looks like the other (default new) profile.

The existing profile file set was (after this procedure) visible in

C:\users\user\appdata\local\mozilla\firefox\profiles

The restored profile is running now as "Default User" and reflects the folder I transferred from the old machine (except that I changed the word "default" in that folder to "main", leaving the number-letter part and the dot unchanged.)

No errors were indicated from firefox (which is running version 83 now) during any steps of the old back-up/archive save step or the new restore/recover step.

What am I doing wrong? How can I recover my existing profile data? The procedure, while not very friendly, seems straightforward enough. I don't want to go into the details of recovering specific database files/folders; I'd just like the profile I had before functioning in the new machine.

Please help

This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

I had to reinstall win 7 on a new HD. Before I removed the old HD I copied my entire firefox profile. I then re-named it to my 'new' firefox profile - in hopes that everything would transfer. My bookmarks are there, but my passwords are not. Although the files key4.db and logins.json are both present in the new profile - they do not contain my old passwords. file size is also the same - very odd. I have access to all data on my old HD - how do I recover/transfer all my old passwords - there are >150 of them - I'm not going to type them all in

thanks so much

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?

What setting will stop the constant notice "Download the latest version of Firefox." I don't want 20 notices per day. It's like having a child in the backseat "are we there yet?" "are we there yet?" "are we there yet?" How many times do I have to click the "Dismiss" button before this stupid software understands that I do not want updates? I've noticed that this is a common complaint.

Usually when i clicked on pdf files, they would open in a new tab where i could view them. More recently, it would always ask what to do with the pdf file. Today when i clicked on a pdf file, it asked me again, but when i clicked to open with firefox it just started to open 90+ new blank tabs, untill i forcefully shut down firefox. Up untill today i didn't change the my firefox options, but it just started changing the way it reacts with pdf files. Today i tried changing the files and aplications options to preview in firefox (i read in some firefox articles that this option was suposed to be the one i used to have), but it would still ask what to do with the file, but when i clicked to open in firefox, it would also download. I then changed to open with firefox in the options, but it would just open 90+ new blank tabs. If i tried to always ask (which i find very annoying, considering i spent +1 year without it always asking), it would also download even if i specified not to download but instead open in firefox. When all failed i tried to reset all firefox options, but thje same problems still happened, after that i updated firefox (something i did for the first time), but still the same.

I'm downloading lots of JSON files on day-to-day basis and I'm tired of selection download action because FF doesn't have a "remember" checkbox for it (see image below).

You can reproduce it: go to any site that allows you to download jsons, e.g. https://petstore.swagger.io/#/pet/findPetsByStatus

If you execute any request there will be a `Download` button If you click it you will see a popup similar to attached one: no "remember" checkbox.

How do I make it remember my choice?

My FF version is 77.0.1 (64-bit), Windows 10 2004.

So I've been using Firefox for quite a while now, both at home at work and on my phone. I've never had any issues with anything. I've had the same 3 extensions running since the installation of Firefox(Momentum tabs, Popup blocker and uBlock Origin)

But recently, Firefox has been uploading insane amount of data to the point where it just does not make sense. I'm adding two images, 1st shows my trend over the last 4 months while the 2nd shows how much data Firefox has been sending while being on (with a reset) for about 4h.

It became an issue because i usually do not close my computer and leave Firefox open with the tabs open (on average 5) and it was consuming all that data while i was at work While a "fix" could be well, close your Firefox, if this keeps up I'll just switch browser.

As far as what tabs are kept open a few Stock images website, GogoAnime, and usually my e-mails or work where i've left it off. No streaming website is left opened

I've got no active VPN connections, I've got complete control of my network and am beyond 100% certain that the issue comes from firefox, no other IP are on my network and lastly disabling all of my extensions has not changed the behavior of Firefox. My Firefox is up to date, (70.0.1) so everything else on my computer, from windows, gpu to all other drivers

Any help would be appreciated, otherwise i'll just change browser. (tried leaving on Chrome and it hardly uploads anything whatsoever)
