I use Firefox version 103, the old version that is perfectly compatible with an extension I always use. I love this old version, and I don't want to update it to the new version. But the update reminder pops up many times everyday. it's so annoying. I used "about config" to turn it off (see photo 2); it works a bit, but the popup still there once daily after the configuration. I want to turn it off permanently. Is there any way to do it? Thank you very much!!

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

Hello everyone,

I'm currently consuming APIs hosted on an external server using Java( or any other server side language), and everything works smoothly. However, when attempting to consume the same APIs in JavaScript, I encounter the 'Access-Control-Allow-Origin' error.

After some research, I discovered that browsers implement security checks leading to this issue. Can anyone advise on how to disable these security checks or resolve this issue when accessing the website in the Firefox browser? Any insights would be greatly appreciated. Thanks in advance!

My current install of Firefox seems to be corrupted, because every time i try starting firefox, even in safe mode, it says "Could not load XPCOM". So my only option now is to reinstall, but i have some password and my search history and bookmarks and generall data to backup. So my question is how can i do this. Im on a Windows 10 22H2 Machine, and i am a pretty expirienced computer user.

I have just started using Firefox and ticked that every internet tab is Firefox but every time I click new tab, it states "search with google or enter address" I cannot get into about:config to then get to browser.newtabpage.pinned How do I get rid of this Google message?

I am facing a critical problem with my website when accessed through Firefox. The browser is not properly loading my website; instead, it cuts off the page and frequently hangs, causing a frustrating user experience. This issue needs urgent resolution as it affects the accessibility and functionality of my website for Firefox users. I am seeking assistance to diagnose and solve this problem promptly.website

Recently I have run into an issue where any site I am logged into will not save that I am logged into that site if I close the tab or window. For example, if I am logged into YouTube, exit the tab, and open the same site in another tab, I then have to log into my account again.

I have tried this solution already: https://support.mozilla.org/bm/questions/1342460, to no success.

While on michaels.com I click on a product, it goes to the product then immediately the screen goes blank. It also happens when I do a search, multiple products show up, then the screen goes blank. I don't have that issues on other websites. What is going on and how do I solve this issue?

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

Had to reinstall my pc over consistent error messages (thank you windows 10 for being the same pos system), and now all my bookmarks are gone, the bookmark backup folder is also empty, I have two years worth of personal and business related sites saved that will cripple me financially and mentally if I can't get them back.

Reaching out to Sync to try that, but looking for any kind of alternative fix here to recover the bookmarks.

I have Windows 10 with current maintenance and current version of Firefox.

Don't know what the address bar is called, but I believe it once had a download icon. Am I mistaken?

Sometimes after I enter an address there will be an icon where I can download something. Is this website-dependent?

Firefox is running x 8 in my task manager at the moment. Why does it keep multiplying and slowing down my computer? I am almost ready to uninstall Firefox. If I merely need to revert to an earlier version of Firefox, please let me know how to do that. Thank you. Shannon
