Firefox-Hilfeforum

I will be receiving a new HP Laptop to replace a 2013 Dell Inspiron desktop and would like to to transfer my Firefox browser, settings and bookmarks when it arrives in a couple of weeks. Can you help with the easiest way for me, who has some knowledge but not the greatest at Tech. ? Thank you !

I have a PC with Windows 7 64b that I have updated after having synchronized with two laptops and one Android. After that Firefox works on all the units except the PC. On that I can see all Firefox shortcuts and Firefox account. But when I try to connect to a web place the screen is blank. I have also tried to sut down the computer and start again. No change. RAM memory is okay, storage on unit C: is a bit small and the CPU is Intel Core i5 3470@ 3,2GH instead of Pentium 4 and 4GH. Should I go back to an older version of Firefox that is not som demanding or is there someting else I can fix?

Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

• https://support.mozilla.org/en-US/questions/1257997
• https://support.mozilla.org/bm/questions/1258023

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.

After wipe of drive and reinstallation of Ventura by the Apple Store, and migration from Time Machine, Firefox won't launch. It's there, but it won't open. Click the icon and the icon moves as if it were going to launch, but the app doesn't open. If I were to reinstall Firefox, would it sync with my settings and Bookmarks?

There was a hardware problem with my iMac; the Apple Store fixed it and in the process wiped the disk and reinstalled Ventura. I then restored from Time Machine. Most things work, but Firefox is one that doesn't. It will not open. If I click the Firefox icon in the Dock, it looks like it's going to open --- the icon moves to the right and bounces back --- (something similar happens if I click on the app in the Applications list), and then Firefox fails to open. No error message or anything. Firefox is still opens on my iPad and iPhone. Would it be of any use to reinstall Firefox? Would the new installation automatically find my Bookmarks and sync with the iPad and iPhone?

Hi, my 2008 Mac Pro uses OS X El Capitan, version 10.11.6 and I am on Firefox 78.15.0esr, I cannot install the new upgrade. Can I continue using the older version of Firefox even though the sync will not work anymore?

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.

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.

Hi jscher2000, I want to thank you for your advice concerning a problem I had downloading Firefox to my Windows 10 laptop. I tried to follow your advice but was not successful. In the end, I googled "what if Firefox doesn't install". It took me to a website, https://www.makeuseof.com/fix-firefox-not-installing-windows , which took me to an article entitled "8 Fixes to Try if Firefox Won't Install on Windows". I tried #1 and #2 without success. #3, Temporarily Disable Your Antivirus Software, worked. Firefox is up and running. Feel free to share this with anyone who has a similar problem. No guarantee that it will work, but its worth a try. Again, thank you. drzee1946

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!

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 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.

Is this real or a scam? Thanks.

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]

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?
