Firefox Community Forum

Firefox is my longstanding browser (on Windows 10). I wish to make use of the Firefox PDF viewer, but have been unable to gain access to it. If for the purposes of an attachment I click on "Open with", Firefox does not appear among the viewers offered. I'm not tech savvy, so a step by step (idiot's) guide as how I can gain access to and then make use of the Firefox as my default PDF viewer will be greatly appreciated, please.

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

Had to reformat and reinstall my Intel Mac with System 10.4.11. Can't download install dmg from the ftp site because my id and password don't get me into the FTP website.

ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/3.6.28/mac/en-US/Firefox%203.6.28.dmg

Does anyone have the installer for 3.6.28 version of Mac Firefox

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

Greetings,

When I started getting msgs saying my browser was no longer supported, I checked my version. Firefox says i have v115esr and that it is "up to date" - i.e. no update available at this time. I assumed I was getting the brush off from those web sites.

Why did Firefox not bring me up to v124? I get a "download update" probably once a month. It's been giving me a new variation of 115esr all along.

I've now downloaded 124 from your site. What do I need to do so that I stay current in the future? Thanks John

i do not want the new update of firefox, and theres no way to shut off the updates. i can only switch to ask me when to install and manually install, not that i do NOT want to EVER install the latest firefox, because it truly SUCKS. it screwed up all the fonts everywhere on the web, somethings are huge and others are too small to read. i woke up a couple of days ago to an unreadable internet. i had to reinstall the last update before this one, start from scratch with all my passwords and a lot of hours of messing with my computer just to have it bearable and able to read my emails. now it keeps prompting me to install the latest. like every few hours i get an annoying pop up to install the latest. then to get it to go away i had to click on something, that downloaded it even though i dont want it. i seriously may have to switch browsers and abanadon you all completely because thats how bad your latest update is, and thats how much it sucks to not be able to stop it form harassing me every few hours to instal it....with no way to turn it off completely that i do not ever want the latest crap update.

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

I recently migrated data from my old MacBook Pro to a new MacBook Air. I installed Firefox on my new computer as it did not migrate. It installed fine but will not launch. Please help.

Can somebody give me a version of firefox for my windows 7 professional (64 bit os) that actually work. I literally downloaded many versions of firefox (esr ones,normal ones) with exe and msi installers. But everyone one of then never works,sometimes it doesn't even install or sometimes it installs but gives error , sometimes it says we're sorry , sometimes it installs but doesn't open nor does it gave any error window. Im getting a headache.Please somebody help me (╥﹏╥)

I tried to download a file and got an error that said "exceeded the maximum number of connections to this server" so I researched it and it told me to type about:Config in the address bad and I would get a configuration page that said "Advanced Preferences". I didn't get that page, I only got a page with a long list of things I didn't understand but I found "http.max-persistent-connections-per-server" and I changed that from 6 to 15. Will that help? I've never ever had problems downloading files or multiple files before. What else should I do so I don't run into this problem anymore? I didn't see anything in Firefox Settings that would help configure the settings.

Hello, please is there any chance to add Firefox download for Linux and aarch64 platform to the download list? The attached image shows that you currently offer a binary package for the aarch64 platform only for Windows. Thank you.
