I use Firefox as my business email and all was working fine until I upgraded Firefox using my Safari browser and created another login profile based on my personal email. That's when the error 'a copy is already open' began. To solve it, I did the above and had two profiles a 'default' and a 'default-release'. I believe I deleted the 'default', and the problem remained. Then I tried a reinstall, and I suppose that's the 'default-release-1' profile, but I really have no idea. The problem for me is that I need to import bookmarks, the business email account linked to Firefox and Host Gator, and all my LinkedIn, MailerLite stuff. I do not want to lose all this and just do a clean reinstall. However, now because I can't open any version of Firefox, I have no way to access the business emails, etc, so I can't recover the Firefox account linked to this business email and get all this stuff back. And I don't know which of the above three profiles I need to delete to get it all working again. Please help!!!

Hi,

My Firefox sync data for a specific addon is messed up. I believe the temporary containers addon made Multi Account Containers addon to sync an insane amount of containers, maxing up the sync storage. Now whenever I click to sync MAC, it downloads thousands of 'tmp' containers. It refuses to sync ever again, hence no matter how many times I fix it locally, if it ever syncs again, it downloads the thousands 'tmp' containers again. How can I delete the sync data for good?

Firefox is crashing almost immediately after loading a page. Sometimes it crashes while loading the page, sometimes I can scroll down or click a link, and then it crashes. Biggest issues are on Reddit. I'm able to browse the Firefox support pages with minimal issues (although it has crashed once or twice).

Crash happens in Safe Mode. (I'm in safe mode right now and it just crashed) I did a FULL clean install about a week ago. (actually did it twice just to be sure)

Not sure what info you need in order to help, but here is some of the crash report from the latest one today.

Hello, I always download mp3 files inside webs using "Save as" and ".mp3" method. Sometimes I had to explicitly save filename with ".mp3" extension to force audio download. However trying to download an audio no matter what format I write in file always download only webpage as .html never as .mp3. Looking at sourcecode (image attached) I found a detail containing "chrome" in webpage. Later, I tried downloading with Chromium at it worked properly. Does anyone know how to download this from Firefox?

Thanks in advance for your help. P.D. I am using Firefox 84.0.2 (64-bit) for Ubuntu canonical - 1.0.

Since the latest update, "Other Bookmarks" has taken up residence where I cannot remove it, so having never seen the folder before I decided to check it. Almost nothing in there is bookmarks. Near every page saved to the "Other Bookmarks" folder is a seemingly random page from my history (deleted and not) up to within a recent few months, which it then becomes my actual primary bookmarks (which I'll have to move, great to know my bookmarks started getting saved to a different folder). Is this meant to serve as an invasive ~highlights from your history~ a la your homepage thumbnails when none are pinned? Or is it some kind of absolutely wacky error with it trying to stuff my history into bookmarks? I'll emphasize just so it's not mistaken, up until the last few pages, every single page saved in "Other Bookmarks" is a random page from my history in chronological order, they are NOT bookmarked and have no reason to be. What causes this and why is this even a thing?

Hello!

I can't use Netflix on my old Windows 7 machine. I'm sure my computer can handle the transcode but just in case - it runs an i3-2330M with 6GB of RAM. When I hover over a title, I can see the preview but when I click it, I end up with an error message. I run the latest Firefox version and have also restarted to check if it works but alas, to no avail.

I have attached an image below. Also, just in case, I have done the adjustments to Firefox's configuration from here.

All help would be appreciated!

PS. Not sure if this helps, but Firefox couldn't play Spotify either! When I open the web Spotify player, I can see my playlists and such, but when I click on any song/album/playlists's play button, it doesn't respond at all! I have resorted to using the app, but am mentioning just in case if it helps figure out the problem/for other users having the same trouble as me.

We have a web site which is working perfect with all other modern browsers except Mozilla's. For this reason we are redirecting the users ,who uses Mozilla browsers, to another page that is saying Mozilla Browsers are not compatible with this web site and please use another browser. But this is not a good user experience and we need help about this problem. The problem is that; on a page there are divs which are hidden by default (with css 'display:none;'),and when a user clicks on a related button, a javascript function named as showhide give response and show the hidden div by making the related div unhidden ( with js command document.getElementById(arguments[0]).style.display = "block";) or on next click ( vice versa with js command document.getElementById(arguments[0]).style.display = "none";) This is working with all other modern browsers except Mozilla's. We tested this situation approximately for 6 months with the most up to date versions of Mozilla but nothing changed. Now we are using version 84.0.2 64 bit but nothing changed. We will be very glad if you can help us about this problem. With our best regards

I have configured FF to block all cookies under "Browser Privacy" the custom setting allows "Choose which trackers and scripts to block. and I selected "all cookies". Knowing that all cookies will be blocked I logged into office 365 and allowed manually cookies through "view page info" I then selected "set cookies" to allow expecting full access to office 365 mail, but this did not occur. What happened is I logged into office 365 and could see the icons and my login name but could not read the mail.

Office 365 gave the message "we couldn't sign you in please try again" yet I could see my log in name and the office 365 icons for mail, calendar etc.. just not the actual data. If I allow cookies in Browser privacy (which i take it allows cookies always) it woks.

I bring this up because it seems like something is missing in cookies that is not represented in FF.What is the difference between browser privacy cookies and allowing it through view page permissions? Can anyone offer an explanation?

i've been having specific issues with firefox with audio files, seen in example on some specific websites where audio will refuse to play. this is not the case on other browsers on my computer, where files will play perfectly fine.

i've found this is the case on both the osu! website (the popup audio player will appear at the end of the site, audio unplaying) and the bandcamp website (bandcamp player attempts to load audio, shows loading screen, then skips to the next track). i've only experienced this not happening on soundcloud, although there are probably more examples out there for both working / not working cases. does anyone know a fix?

I looked around and couldn't find where to file a complaint, but I've seen that someone else did it here before. If this is the wrong place, please forgive my error and make sure it gets to where it should be.

Although I believe Firefox, as the last mainstream browser not owned or operated by a major tech company, is critical to keeping a more independent web, I'm very frustrated with a 'quirk' in developer mode.

It seems to unpredictably, randomly switch to 'original sources'. Normally it is an annoyance, not a critical issue, but this evening I was working on restyling a page's CSS, had gotten a fair chunk of work done, and of course, hadn't saved my progress. When I selected an element and went to edit it, Firefox pulled up the original source instead of the modified files I had been working on, and then overwrote everything that I had previously changed after I made the edit.

The fact that I didn't save my work is on me and I accept that, but the fact that Firefox decided to switch to the 'original source' instead of the modified files I had been working on without problems for over half an hour, and then offered no way to get back to the modifications I had been making, is not.

After experimentation, the 'original source' checkbox doesn't seem to do anything when I toggle it, which indicates to me that it's either buggy or the interface is not clear about what and where things are being changed. I only remember this becoming a problem relatively recently, so I'm willing to give the benefit of the doubt and assume that it's broken, but whether it's a bug or it's intentional behavior, it ought to be changed.

Thanks for your time, attention, and patience.

I want to use HTTPS-Only mode, but Firefox enforces it on my private network as well as the public network. Because I do not have certificates for any of my private network hosts HTTPS-Only mode blocks all internal network traffic. The suggested temporary workaround is impractical. Is there a way for Firefox to check the hosts file for a local name/ip or is there another fix for this?

Hello, for the past week i've been tackling this problem and it's driving me nuts. I've basically replaced FF with Chrome at this point, because I can't use it for work.

Firefox refuses to print, no matter which printer I select, and even if I try to print to .pdf using Microsoft Print to PDF (or other, 3rd party ones, I tried). Other programs and browsers print just fine, it's only FF that refuses, and it refuses to do so with any printer, physical or virtual.

The error I get is a window titled "Print Preview Error" and the error message is "An error occured while printing" (see attached image). For what it's worth, when I go to the menu and select Print, I get the print preview just fine, it's only after I move on to the printer selection and click on Print that I get this error.

I've followed all the steps from: https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox as well as: http://kb.mozillazine.org/Problems_printing_web_pages#Reset_printer

And I've also tried using Safe Mode while doing that, as suggested here: https://support.mozilla.org/en-US/questions/854093

I hope you can help! I've been a Mozillian for more than 20 years, contributor, and volunteer, but this is making my work impossible and I'm forced to abandon FF due to this problem.

Hello!

I am using Firefox on my notebook with external monitor.

When the external monitor is set up as the main display and above the notebook monitor, the toolbar popup menus in Firefox are cut off on the notebook monitor (≡ & addons like uBlock etc.), so only a small upper part of them is displayed. The ≡ menu can be fully operated in this case because it has scroll bars, the addons' menus do not.

If the notebook monitor is set up as the primary monitor or is not below the external monitor, the problem does not occur.

Disabling all addons does not cause any change.

The problem does not occur with other browsers either.

Would appreciate some help!
