Firefox Support Forum

Hello,

I am trying to download Firefox source code. I tried the simplest option offered to me : https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Using_the_VM But the link to the Virtual Machine does not work. Do you know if the site will be back soon or will I have to search for another website offering this VM ?

Sorry for my bad english. I hope my question was clear

I'm scared af. Hundreds of password are saved on my firefox. My active logins were revoked and I had to reset the password to login to my firefox on windows. Turns out all my passwords are gone.

I have no email from firefox notifying of the suspicious login.

What I can do?

I'm new in Firefox Developer Edition. I have a web app which has been developed by asp.net mvc and c#. There is a code to upload a file to a network path by clients on an internal server. While debugging the code, it works without any issue on Chrome but on Firefox D.E. I got access denied error while accessing the network path. (I spent 2 hrs to figure it out that the issue is being caused by Firefox D.E)

Does anyone face this issue before? is there any solution to fix it?

I get that I need to have certain addons only for the developer Version, but I've been having difficulty keeping up with what I need for one and ones that meet my specific needs otherwise. I can only type using one finger at a time due to my autism causing poor coordination. I've been having trouble keeping my gmail synced up in places and it's the mail one I use. But I can't sync my password to different devices as it always asks for a password I haven't used before. I am happy to keep the addons proper on the developer version, and not use it for anything until I ca get it set up without having to re-sync everything. Do you have a suggestion for limited motor ability?

Hi,

Is there a way to delete webauthn credentials?

Using webauthn.orgwebauthn.org :

I registered user 204348 more than once, which works.

When I go to the login in page, Windows asks for my credentials.

This is where the problem is:

It gives me more than one sign in option which makes sense.

My question is, can you delete a credential?

hello,

What's a pity with this video overlay option is that the subtitle does not accompany the overlay but remains in the original page.

What would be interesting is to have the subtitle accompanying the detached window.

Do you think it's feasible to recover both the video and the subtitle in the main window?

Hi! I just installed Firefox in my Debian 10, that I have just installed. I have to install several users in that old Mac Mini that was going to garbage and now it's working again!

I decided to activate Sync in order to keep working in the same pages from one session to another - handy! But after I login, the next page is a 500 error! This has ocurred in my Macbook with macOS, as it should, but thought I should report somewhere.

What is really strange is the logout button is not available in user menu as in the mac version, this is odd. It tuck me some hard time to manage to logout! Guess is a real flaw...

But my tests has worked really good in that old hardware!

I'm having a weird problem where 4k videos that are scaled down to say the normal YouTube player size look terrible, hard to find the right word to explain it, but edges are jagged. It improves a lot if I full screen the player to presumably closer to 4k dimensions.

Changing playback to 1080p looks better than 4k, again I'm sure it's to do with scaling.

• I don't have this problem when testing the same videos in Internet Explorer.
• It's not just my videos, other peoples videos are doing it to.
• Updated to the latest version of Firefox.
• Updated my GPU drivers (MSI Nvidia GeForce GTX 1660).
• Tested in Firefox safe mode and disabled/enabled hardware acceleration.

I'm running out of ideas, so any suggestions would be greatly appreciated.

I changed the password for the firefox account because I installed a new windows, after which all login details and bookmarks disappeared. during the password change I was not informed that I would lose all data! I let you keep this information in the cloud in trust and you deleted it? Have you gone crazy!?!?!?!? I want to get back my data immediately! I see that a lot of people have a similar problem and you don't do anything about it? How can I trust you at all in this situation?

I have a web page with a link to a PDF on it. When I click on this link, the PDF opens in a new tab using the Adobe viewer, and displays fine. However, links within the PDF itself are ignored. When I view the same web page in Chrome or IE, the PDF also opens in a viewer, but under these browsers, the links within the PDF itself work as well. Is there any setting or adjustment I can make to Firefox or its PDF viewer to make the links within the PDF work? Thanks for any help. WJH

I have been running on Windows 7. Upgraded to 10. Cannot set Firefox as default browser at this time. Do I have to download Firefox again? Will I lose all my saved passwords if I do? Thanks. Janice

<rant> It is just so tiresome to repetitively figure out how to restore my searchbox after major updates.

I *don't* want to use the combined address/search tool. I use the search box as intended with about 8 search tools in the select field to choose from.

It is just arrogance on FF's part to remove it over and over.</rant>

After today's update to the newest version of Firefox, my bookmarks and history are gone. I can't even ADD bookmarks! I looked for both through "Library," and nothing. Please help. Thanks in advance.
