Firefox Community Forum

I'm trying to install & use Firefox as my browser of choice on this new computer. Using the migration assistant, Firefox seemed to transfer to the new computer with no problem, except that it did not work. Neither does, apparently a new installation directly on the Mac Mini. Any suggestions? I do prefer to remain with the new operating system if possible

Thanks,

Hi everybody. Thanks in advance for your help.

I'm on Win 11 23H2, and I'm currently running Firefox 88.0.1 x64. Why? Because it's heavily customized to suit my needs. Some examples:

• Extensions (e.g. Classic Theme Restorer)
• userChrome.css and userContent.css customizations ( https://github.com/aris-t2/customcssforfx ), which include tabs on bottom (mandatory for me), tab height/width, and many other things.

I decided a long time ago to stay with v88 because every new Firefox update was breaking things that I needed, and I got tired to spend hours with every new update. If only Firefox devs could find a way to NOT break user customizations with every new update...

Of course I'd like to update my Firefox to the latest version. But I know that it's going to be a nuclear bomb. I already made a test. First I made a backup of my profile folder, then I just updated Firefox. Suffice to say that not only all my customizations disappeared : even my tabs disappeared, and I have dozens of them. So I had to uninstall everything, copy back my previously saved profile folder (because of course it had been modified by the latest version), and reinstall Firefox 88.0.1.

So here's my plan and my question. Would it be possible to have two different Firefox installs (not portable I guess), with two different profiles, running at the same time?

• Here's how I see it:
• Download Firefox latest version
• Close Firefox 88
• Move profile folder away from AppData\Roaming\Mozilla\Firefox\Profiles, so Firefox latest version can't find it
• Move Firefox folder (the one within Program Files) so hopefully Firefox latest version can't find it
• Install Firefox latest version (it then creates a new user profile folder)
• Start Firefox latest version
• Move back the old Firefox folder to Program Files (so there will be two different Firefox folders, e.g. "Mozilla Firefox 88" and "Mozilla Firefox")
• Move back the old profile folder to AppData\Roaming\Mozilla\Firefox\Profiles (so there will be two different user profile folders)
• Start Firefox 88

Would that work, or am I missing something?

If it worked, then I could keep working on Firefox 88, while gradually customizing Firefox latest version until it's ready to take over.

Thanks in advance for your insights!

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.

Recently I have found that I cannot download statements from my bank account, also at the same time (2/3 months ago) I cannot access a Tesco website from Firefox. I can carry out these functions easily from Microsoft Edge, so why the sudden change ? Can anyone please help me to fix this in Firefox?

I've noticed that when I use my VPN the Broadband data volume measured by my Glasswire traffic meter software monitor is doubled. I've tested it numerous times, and when I download a file it appears to download it automatically to Cloudfare as the volume is almost the exact double of the file size and double the amount as measured through my VPN. Could this problem be associated with the DNS over HTTPS feature. I've changed this setting so that Cloudfare doesn't load anything automatically, but there is no change. Is there another automatic Cloud setting I should change or could this problem be independent of Firefox. Thank you. -Reply to moderator Co-rel "answer": @Co-rel, You are not answering my question. And are you inferring there could be a bug in my Firefox version and I would need to debug it myself? I am asking if there is a default setup in association with Cloudfare which would record all of my traffic and/or downloads. I've canceled the default DNS to HTTPS Cloudfare default. Is there another automatic default service clouding to Cloudfare storing our data automatically built-in Firefox? My Traffic and Data Monitor Glasswire records or measures my traffic as anticipated when I browse without using my VPN. But when I use the VPN the data count is doubled and what newly appears on the register is the URL of Cloudfare which is the same size approximately as the file downloaded, doubling the traffic. I tested by isolating a simple maneuver of downloading a single 150 Mb file. I did it twice with the same result. I did the same thing twice with a 1 Gb file last Wednesday, got the same results.

Hi, My computer died and I can't access it. I tried to sync firefox but it wont let me as I did not have my original password. All of my personal medical links and billing links are bookmarked there. Is there any hope to get it to sync?

I had posted my question yesterday and received a response from jscher2000. I sent a reply to the response by email a short while ago, but I wasn't sure it went through. Therefore, at the possible expense of having you receive the reply twice, I have recopied it here:

Thank you for trying to help me download Firefox onto my computer. As per your advice, I first tried shutting down and restarting my computer. That did not work. Then I went onto the link you sent me: https://www. mozilla,org/en-US/firefox/all/#product-desktop-release . The installation began, but only got up to around 80 - 90%. It stopped at the point where it said Execute: "C:|Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046B... (It looks like there might be some more letters and/or numbers after the "B", but I can't see what they are.) I waited a few more hours to see if the installation would continue, but it did not. I then went back to try downloading Firefox in the regular way. First I got a message, "Now installing. Firefox will be ready in just a few moments." Again, installation proceeded to around 80 - 90 %, and then I got a message, "Hmmm. For some reason, we could not install Firefox. Choose OK to start over." Starting over didn't help. I got the same message. Any further help or advice that you can give me would be greatly appreciated. drzee1946 email: [removed from public support forum]

Is this real or a scam? Thanks.

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

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.

I have been using Firefox for quite some time. Suddenly it stopped working on my computer, I tried uninstalling and reinstalling, but I keep getting a message that there is a problem with the download and installation. Can anyone help? Let me know if you need any further information. Thank you in advance.

I know my password is " [edited from public] " but you keep saying it's wrong! Why? It has always been that! Please, I am trying to update Firefox as per your directions!

Ark extracted Version 119 files into /home/Downloads/Firefox/Firefox. I tried ./update from the BASH command line, but didn't know which argument(s) to add to that command. I'm hoping to update Firefox 78.14 ESR to a recent version, whether ESR or not. Thanks for your help.

Since Firefox updated? a week ago we have lost our browser and can not install a new setup. The cursor freezes before we can finish the new install. Any ideas for what to do? We did like Firefox before they fixed? it and we lost use. Thank You.
