Firefox Support Forum

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!

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

Hi all.

My sync is only sometimes working. I notice that when saving a bookmark and trying to find it on another device. I sometimes have to manually resync it or wait for a few days to get it shown on my other devices. Same with the tab sharing across devices.. In most cases it doesn't work at all..

Here is a current sync-log: https://pastebin.com/TWugtAbm

Is there a way to set the default view and sorting for file upload folder?

The default for me is, detailed view and sorted by date.

I wanted to change it to large icon and sort by name, so it's easier to upload images. but I have to change the setting for every individual folder, is there a way to just set it as default?

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!!

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

anytime I type www into the URL window firefox autopopulates youtube.com even though I have turned off auto suggestion. It shows up before the bookmarked links !

it always automatically checks the "Search suggestions ahead of address bar results" and will not let me uncheck it.

I just dont want it to suggest anything and am okay typing the complete URL. How can I fix this issue? I am including snapshot of what the autosuggestion, settings and version info in the attached doc

My LastPass extension appears as a black box with an elipse. It is red when it is active. I have logged in to LastPass, and when I go to the extensions icon and select "Open Extension" nothing happens. It's not filling in any of my login information.

Firefox browser no longer on W7 laptop. Followed instructions-downloaded setup and installer. Neither will do anything - message says no program association to implement thses files. Help!

Please return the scroll bar to the proper width like in Win 10, like Chrome in Win 11. Who's the idiot that thinks tiny thin scroll bars are cool and easy to use? tf is wrong with you idiots. Don't offer me solutions. You are the solution. Update firefox, fix the damn scroll bar.
