I run Firefox on a number of systems and two of my work computers seem to be unable to check in with the Firefox update servers to get updates. See image for the exact error message.

"Firefox can't update to the latest version. Download a fresh copy of Firefox and we'll help you to install it."

My suspicion is my network team is blocking my browsers from getting to the Firefox update servers but I don't know how to test it. One of my browsers is 77.0, the other is 77.0.1. Both of them give me the error in the image. Both of them insist I'm on the latest version of Firefox when I use 'Help/About Firefox' to check.

If anyone knows what data I should collect to get this figured out I'd appreciate it.

Thanks

Hi, I'm trying to run and use Firefox as my default browser on Windows 11, but I'm running into some issues. The device is managed by Microsoft Family, which blocks Firefox by default. I got around this by renaming "firefox.exe" to something else. This works to get Firefox open, but the modified filename is causing Windows to not recognize it as a browser. As a result, I can't get Firefox set as the default for http/https.

I've tried tools like SetDefaultBrowser from Christoph Kolbicz but no success, it is unable to notice that firefox no longer exists as "C:\Program Files\Mozilla Firefox\firefox.exe"

Anyone have any advice on how to fix this? Windows seems adamant not to let me set the http/https protocols to anything it doesn't think is a browser (i.e. my Firefox installation).

I use Firefox as the browser for my email. Recently I have been unable to open or download pdf attachments (or any attachment) to emails. When I click on the attachment I get the message javascript:void(0).

I contacted the email company who said there was no problem at their end and that the problem was with Firefox and pop up blockers. I followed the advice in the attachment to unblock for my email account - but this did not solve the problem.

So I then tried Edge for my emails and I can open attachments in Edge.

So the problem is with Firefox.

Any advice please? Thanks

I'd love to have Firefox release version and Firefox beta installed side-by-side on my Mac. Is it possible? If not, how do I make it so without encountering weird problems? If any from Firefox's dev team are reading this, please just make this possible. Chrome and Edge do it. Firefox should, too, IMO. Thank you.

I think I may have downloaded and installed a fake/malicious application that looks/acts like a Firefox Browser installer. I noticed a lot of suspicious activity on my personal/work computer that led me to suspect my internet router was compromised. I work from home sometimes and I may have been tricked into downloaded and installing a malicious version of Firefox.

I suspect this Firefox installer is different because this installer is capable of circumventing the safeguards placed on my work laptop. My work laptop is managed by a university and I require an administrator's credentials in order to install/uninstall any programs, change/view any environment settings, or even open up and view task manager. This process entails actually having an administrator remote into my laptop, take remote control, enter their credentials, and ensure the installer completes.

So far, this unusual Firefox installer is the only installer capable of bypassing these security hurdles. And it does not detect any existing versions of Firefox to prompt an uninstaller before re-installing. The installer's visuals/progress bar appears to be a scripted animation.

I still have the installer in question saved on my computer and I'm not sure what to do with it. I'd like to find out more about it but I'm not sure how to go about it.

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

Howdy, fellow Firefox aficionados.

I'm running FF on a Windows 10 Home 64-bit desktop. Some time ago, I suddenly could no longer open Firefox because it couldn't find my Profile. So, I attempted to create a new one, but it would not allow me to do so.

"Changes Not Saved"

   "An unexpected Error has prevented your changes from being saved."

[See uploaded Image]

More than likely, either I, or one of my system maintenance programs wiped some data or folder. I have deleted Firefox and reinstalled it with the latest version, but this dilemma persists.

Thanks for reading my post and if you reply, a big Thanks!

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".
