Hi, Apart from some references I had found going back up to 10 years, I cant find anything about making Firefox run completely from a usb stick.. I have used an appimage to install it on a usb, BUT it still creates a folder with the profile in the Home directory on the PC hard drive.. Can you please give me some idea of how I can move the folder location from the hard drive and have everything pointed to the usb.. I have used the profile manager to create a new profile based on the USB, and then deleted the Mozilla folder on the PC hard drive, but that breaks FF. So obviously even though it is residing and running from the usb, it is referring to the hard drive for something.. Running Ubuntu 20.04 David B

At one point I installed the newest version of Firefox on my MAC (Early 2008) running Catalina. I found it would not run as that release needs a newer MAC OS.

So I went back and installed Version 78. That did not work either. So I tried Firefox 10.0.11esr.dmg, 10.0.9esr.dmg, and even Firefox.45.9.0esr.dmg.

After install, I get the same message.

You can't use this version of the application Firefox with this version of OS. You have 10.11.6, This application requires 10.12 or later.

My theory is that even though I uninstall Firefox, some trigger file gets left behind and I get this error message no matter what version of Firefox I install.

Anybody have any ideas on how I can run an older version of Firefox?

I have hit the Sept 30 Certification issue with this old MAC and I hope Firefox will be a work around. - Thanks Rod

Same with

Today's update- Facebook shortcuts missing. Followed instructions to update profile. Need 2 separate tabs open- One for Fb, another for the shortcuts. Cannot merge to show on one page as always before.

Please tell me how I can regain control over my own computer, and block companies hijacking or derailing it. I'm very tired of incessant reminders of unwanted updates, as well as their arbitrary limitations, and apparently will somehow have to remove layers of them to regain flash player stolen away by Adobe. If only they had left well enough alone...

The Firefox 78 ESR is the last version of Firefox that supports Flash - how can I reinstate it? Do I have to roll back browser versions to regain control of my own computer? If I had a problem with Flash, I would have dealt with it myself!

Does Open Office respect customers' rights better? I hope so!

Could not install Update 72.0.2 on 10/9/21. (Patch Apply Failed) The results says that the update was installed, but it wasn't because the patch apply failed. Please fix it and let me know when it is fixed at AAN3@comcast.net. Thanks, BJ

Windows 10 did an update this morning and now I cannot access firefox. firefox entry not found. the procedure entry point ?profiler_init_main_thread_id@baseprofiler@mozilla@@YAXXZ coulld not be located in dynamic library. c\programfiles (x86)\mozilla firefox\xul/dll

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

Hello everyone I re-install my win7 recently. I can get the firefox browser installed whitout any errors but it doesn't open. However I can see it's open in task manager in processes tab. what would be the problem? please advise

Firefox install fails because it cannot find VC Runtime140_1.dll I downloaded the dll but Firefox can't find it. Where should I put this .dll? The bulk of the program installs but it can't search on line.

This is a new Win 10 machine. I've updated and ran DISM.exe /Online /Cleanup-image /Restorehealth then uninstalled Firefox, put the VCRuntime file in the Win Sys 32 drivers folder, restarted and reloaded Firefox. Still no love.

I'm at the end of the road...what next?

When dowloading an AAX type file from Audible, Firefox changes it to MP4 (downloads as AAX with other browsers).

Note, changing the file type after the download fixes the problem. But, is there a way to prevent it from happening in the first place? Also, why changing file type in the first place?
