Firefox Community Forum

I lost my Outlook365 with the latest Windows 10 update. When I reinstalled I went through the preferences to select Firefox as my default browser. I have been using this for years and every time I picked a link in an Email it would open a new tab in my existing browser.

Now, regardless of anything I try it continues to open an new Firefox browser, with pages included since this started on the weekend.

What settings am I needing to make to correct this. I have gone through the config settings and selected 0 in the browser.link.open_newwindow.restriction with no success.

Every time I have tried to use the NPR website's contact form, I get the message, "sorry, something went wrong and we were not able to send your request". Today, I accessed their website using Microsoft Edge and had no trouble sending a message using their contact form.

Can you help me correct this FireFox malfunction? Thanks!

The 'Manage Bookmarks' you have placed at the top of the page is doing exactly nothing. I can't restore them, they are gone. How do I get my bookmarks back, or restore to the previous version where they are still located. Sick of constant updates that just cause problems-about to go over to Edge.

I am deleting or updating accounts linked to an email that was hacked. However, I cannot make changes to this Firefox account that I no longer use because the email that was hacked no longer exists. I wish to delete the account because of suspicious activity. Thank you for your assistance.

Hi, I would like to know which version of Mozilla used this setting of network.trr.excluded-domains: 'sbl-xbl[.]spamhaus[.]org, localhost.that.never.exists'. The default is 'undefined' as I checked in 127.0.1 and the older 124. I also contacted support of extensions that I used, no evidence of both excluded domains. Can anyone help me? Thanks a lot \!o!/

Can you suggest any functions or apps that I must or should avoid? It's important that I NOT use a VPN, and that I use 'open-source' in a probably 'shared access' situation. GRM PL

I have noticed in the past few weeks or so, many video play backs are erroring out on google/news: Example: https://6abc.com/post/middle-schoolers-create-20-fake-tiktok-accounts-impersonating/15039963/

Message is: Media could not be loaded, either because server or network failed or because format is not supported.

IMO not a network issue......

Thanks John Hutchins

do know computers very well, have used firefox for all my web browsing, firefox kept crashing according to screen so it opened saved apparent older version and I lost all my bookmarks and passwords, please help

I stored a password for particular web site. When I reset the password and stored it again. but your site does not revise it. then i try to remove it but you offer to passwords for all websites. THIS PREVENT ME TO STORE PASSWORDS IN THE FUTURE.

I use Firefox to access my bank account, and it autofills the personal id number, and, when I click, the 6 digit code, which I allow it to store, because no one else has access to this PC. BUT, I had to take it in for repair, and give them my Windows login details. When I got the computer back, I went to the bank login page, and the autofill was a different personal id number. Does this mean that somebody used Firefox on my machine to login to their account? Or could a reboot have meant that Firefox randomly changed the PID number? Thank-you for your help.

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

I have been reading the NYTimes on Firefox for a long time, but it appears that I got logged out without knowing it. I could not log back in even though I used the correct email address and changed my password twice. I can log in on other browsers using my latest password. I called the Times and the person with whom I spoke, after trying to get me logged in, finally said that this is a known problem with Firefox. He did not have any idea about the cause or what I could do; he simply told me to use another browser. I use Firefox for almost everything and this is, to say the least, an inconvenience--for instance, if the Times sends me a link to an article by Thunderbird (which is my email program), I can't read the article but have to find it on another browser. Are you aware of this problem? Do you have any suggestions for how I might log in despite it? Do you know the cause of the problem and whether Mozilla is trying to fix it?
