Firefox Support Forum

I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

For some time now I've had an issue with navigation icons appearing as text and not the icon.

An example if this small screen shot under Google Calendar

Note the arrows to go left or right are missing and instead it savs NAV.

I'm having this appear other places as well.

Thanks

I cannot log into my account on www.1688.com. Until recently I could easily log into my account using Firefox browser now it does not work on Firefox anymore I can still login on other browsers like safari and Google Chrome. When I'm trying to login on Safari I put in my account name and password but he just keeps asking for it again and again and doesn't login. What can do about that?

Firefox stopped opening links in web pages like secondlife:///app/region/Kings%20Stone/224/155/22 ,WHere do I tell Firefox what application to use to handle that kind of a link?

Hi, I'm trying to clear my cache and site data (in order to update my gmail signature), and each time I clear selected sites - namely gmail which had hundreds of thousands of GB cached - it just comes back. After tyring this 4-5 times, Youtube started having hundred of thousands of GB cached too!! So now, despite managing data an clearing these repeatedly, there's more than when I started. I think I'm stuck in a loop somewhere, please help! thanks in advance

I have delete cookies on, exits firefox for a while, delete cookies option turns off and all cookies are deleted, even ignores exceptions. How to stop firefox from disobeying its master?

For several days, I've been locked out of a banking website I use regularly (Fidelity) using Firefox on two different computers. However, I can access the site using Safari. I'm using an iMac 24 and a Macbook Pro. I've cleared the cache, have turned off the ad blocker for the site, and have an up to date version of Firefox. Thanks in advance for help.

Last night I was watching a video series on Amazon and the last episode won't play on my MacBook Pro. I plays on the TV and in Safari. I deleted and reloaded Firefox but the issue remains.

I can no longer log-in to sites that require Usersname and Password on my Mac. But I have no trouble using my iPhone to log-in using the ios Firefox and Firefox Focus. I tried clearing the history on my Mac and still no success. The error message I keep getting is "Could not process login". I know my username and password by heart and have had problem logging in before. Just recently in January 2023. I kept trying until I got locked-out. Please advise.

Not highlighting selection to copy or delete so I have no idea where I am. If I cut it does cut what I've tried to highlight on my new iMac--- this issue is firefox related-- works fine in chrome and safari'... I need make this feature work in Firefox-- don't want to move away

This has happened to me several times and I've uninstalled and reinstalled Firefox, but then it happens again weeks, months later. It says to contact Mozilla for a correct certificate but how do I do that. There's no instructions on how to do this. Any help you can provide will be greatly appreciated. Thanks so much.

Firefox frequently refuses to load FamilySearch. I can usually reconnect by clearing cache and cookies, but then it only works for a day or so before it refuses to connect again. I have disconnected enhanced tracking. Google Chrome does not have this problem. Please help me find a solution. Thanks, Sharon

Several websites (not sure it's website-related) are displaying some (or a lot) of unreadable text. If I copy the text and then paste it into a page in a text program, it all reads fine. What could be causing this, and how do I fix it? (Screen shot is attached.)

I am not ultra-technical so please make response clear.
