I have trouble downloading the newest version because it says that Firefox has ended support for Windows 8 and Vista.

But I DO NOT USE THESE OLD VERSIONS - I DO USE WINDOWS 10 on this computer.

Could you please let me know how to fix this in plain english so I can easily do it myself - I am no computer wizzard.

Your help would be greatly appreciated. Please write your answer to my email account: [removed email from public] ,

Thank you, Chris

The computers bookmarks after September 28 and before December 1 2023 are missing as well as the internet history in the mozilla browser only. I see no possible way of restoring them. I see no way to contact mozilla directly about this either.

As the title says:

NordVPN's Threat Protection installed a browser management profile. Now, I can't seem to get rid of it. I've refreshed FireFox, uninstalled NordVPN using App Cleaner, and deleted any/all certs for NordVPN Threat Protection from keychain access.

How can I get rid of the management profile? See attached screenshots.

I've been with yellow folders for several years. In the version that I have now, version 111, no longer works. I was put at userchrome.css the following: @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); .bookmark-item[container], treechildren::-moz-tree-image(container) { fill: gold !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksToolbar) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksMenu) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_UnfiledBookmarks) { fill: black !important; } treechildren::-moz-tree-image(container, livemark) { fill: orange !important; } .bookmark-item[container][query], treechildren::-moz-tree-image(container, query) { fill: dimgray !important; }

I do not know because it doesn't work now. Maybe version 111 no longer admits it? Do you know how to put the yellow folders?

Recently I did a full scan with Microsoft defender and it detected a file in the “firefox/profiles../cache2/entries” as a trojan:PowerShell/Meterpreter.A (And also something related to gzip I’m sorry that I didn’t take a screenshot of the message but I completely freaked out and deleted it immediately after scanning with the other AVs). I installed malwarebytes and Avast and did a full scan they returned with a no malware has been detected. In the moment I panicked and immediately deleted the file (I should’ve uploaded to virustotal to see its behavior and what it can do and change to my PC if it is indeed malicious). Then I did a full rescan using Microsoft defender and it returned with a 0 threats found. However, I only went to a couple of websites recently which as far as I know are safe such as msi, cpuid, I don’t go to shady websites plus I have ublock origins as an Adblock. My question is as follows how much percentage wise this Trojan is a false positive and if it is a virus how much damage it did (the thing that got me freaked out is that it’s a meterpreter)

Firefox just updated to version 120.0 I hadn't used youtube for a while. When I tried to play youtube videos none of them will play, only get a green screen with audio In troubleshooting mode they will play Refreshing firefox does not fix the problem

New user here. My web search results dont fill the screen, they always require scrolling down to see the whole page at once (as designed). why are the top 2 bands 3 times as tall as the font in them, they use up valuable space. see snip insert below. i have trouble enough with windows 10 without squinting and all this needless scrolling down looking for the rest of the buttons. I use LastPass and its truly infuriating how big the boxes are and how hard to find the information, particularly the "go" buttons. TYIA Shandy

Hi, I've set in my settings to use the unified search+url bar, Also I've set Google as my search engine, but when I type a search request Firefox searchs by default an URL, leading to an error every time, I don't know what to change and Ive tried different settings with no change

Need to clear all previous activity [history, cache, etc.]. I create websites. Do NOT save history. Option turned off. When I bring up a changed website, I see the previous version or the one before that half the time. Rebooting PC does not clear it. Am tired of playing browser roulette, trying to find a browser which will A. Show the latest version. [which is being displayed on other people's devices] B. Perform the desired action as designed by the product creator [which works on other servers and devices, and even sometimes on my device using another browser] I am not skilled at seeing physically thru other people's eyes, only imaginatively. My partner is 200 miles away in another state. We don't always see the same, even when the display is identical. Am starting to create 2 versions of sites, a .org and a .com and explaining to people WHY. I think the "don't save" does not work. It merely turns off creating an index of the viewed material and leaves the viewed material in cache. And re-displays the initial data eveytime, no matter how many updates. Thank you.

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

I cannot get screen share, webcam share, microphone share to work with my default profile. I get a Cross Origin Request Blocked. If I create a new profile everything works as it should even if I install all the same plugins. I have tried changing security..cross_origin in about:config and it makes no difference.

I have a lot of tab groups and sorting in my default profile, so I'd prefer not to have to set that up in a new profile. Importing to a new profile ends me up with the same issue as above.

This error is profile specific and I am wondering if anyone knows the specific profile files that I could regenerate, delete or replace to tackle this cross origin blocking.

Also I've disabled all my plugins, and enhanced tracking protection on the default profile and it still does not work..

Thanks.

I need a fix for my ESPN+ account. I can watch live sports and videos but cannot read ESPN+ articles. Everything works great with Edge and Chrome, so maybe I will have to switch browsers.

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

OS: Windows 10 1607, FF - 120.0, issue was present for many versions before.

Firefox is notoriously adept when it comes to browser/user protection, (THANK YOU!!!!!!!!). Are there any plans to include protection against homograph/homoglyph attacks please? I think the simplest way would be to just search the URL for any characters that are not part of the current/usual typeset?

Hello, I have a very odd problem with my firefox browser. I am running firefox 88 64bit on a 16.04 (I know...) Ubuntu. On certain websites, I have an issue with interactive content: www.leboncoin.fr will not let me login anymore (quite recent) www.decathlon.fr will have trouble displaying user comments, images, let alone placing an order Now and then websites with dynamic content and forms will not load...

I am not sure what is the link between all these but it seems related. I have tried the troubleshoot mode but it does not change anything. At the moment when I need to use these king of website I have to switch to another browser.

Thanks in advance for your help!

Hello ;-)

If i try to watch amazon prime video, Firefox crashes the whole system (no further action possible). Taskmanager does nothing, CPU is on 100%. Badly there is no crash report or Firefox log - maybe because the whole system is freezing completely. Widevine has been loaded correctly.

I tried Opera and there is no problem. I tried also 4 several PCs - always the same. Firefox crashes the whole system, Opera is working without problems. I didn´t try Edge or Chrome - i didn´t want to "rubbish" my system ;-)

Sure, i could use Opera, but ... my favorite is Firefox for all the years ;-) The failure appears with version 1.11 - earlier versions had no problem. I´ve only installed privacy badger and no other plugin or extension. Also DRM and widevine is activated. Reinstalling (after registry and install cleanup) didn´t solve the problem. And, yes, i have all recent updates on Windows 10, graphic card driver and Firefox.

The support of Amazon: "no idea" ;-(

Any suggestions ? ;-)

Best regards
