Will not permit me to load an old profile. Your instructions on the recovering data page just feed me into an endless loop of prompts to create a new profile.

The old profiles had my logins for work. I would prefer not to have to spend hours resetting something like 15-20 logins and profiles and then the next two months forgetting what the new ones are.

I get this error message:

The proxy server is refusing connections

Firefox is configured to use a proxy server that is refusing connections.

   Check the proxy settings to make sure that they are correct.
   Contact your network administrator to make sure the proxy server is working.

What do I have to do to fix this?

Hi everyone,

When I open a PDF file on Firefox, it is opening with Adobe Reader. But when I click in a link of a picture in JPEG format en Firefox, it is opening in a new tab in the browser. I would like to set by default paint. How can I change that please ?

Best regards,

NK

Some Youtube videos say "Your browser does not currently recognize any of the video formats available. "

and Amazon Prime "Video Unavailable" is also fixed by this.

I fixed this by installing FFMPEG which installs libavcodec.so.58

DRM Playback is enabled under preferences.

Not sure what the right place for this is; I wasn't able to find a Firefox support forum specifically for web developers. If anybody knows of a more appropriate forum, please let me know.

I'm trying to intercept the opening of a popup window from JavaScript, but I can't find any way to trigger the debugger on this condition, and I don't want to set the breakpoint manually because the source I'm working with is obfuscated and it would take a lot of work to track it down manually. I currently have Firefox 68 ESR, but I could upgrade if needed. Does any version of Firefox have a way to set a breakpoint on new tabs/windows opened from JavaScript, or is there a way to break on the `window.open` function which I suppose is what is being used?

I like to open all urls and links in a new tab because then I don't loose the original tab's contents. So I have set browser.tabs.loadBookmarksInTabs to true. Alas if I click on a link in the history library it still replaces the actual tab. I know that I can do a middle click or a right click to get a new tab but I would appreciate if I could set the standard behavior to open a new tab. Is there a setting for this?

In order to resume a download, there are currently far too many steps required to make it very user-friendly, as seen [here].

There should be a better, integrated way to reliably resume downloads, such as having the reload button next to the file automatically resume the download instead of starting it over.

This is especially important for very large files such as ISO's and archives.

It's good to have those built-in shortcuts, but it's stupid you can't modify them. When I use this website I can't input the division sign by pressing / on the keypad because it's the shortcut for Quick Find. I guess this is because the place to input is not a normal text box like in WolframAlpha , but part of the whole webpage(?). Add the function to customise shortcuts is much easier than let Firefox recognise and deal with this situation, I think. In fact, most software supports customising shortcuts, so I'm surprised to find there's no way for Firefox to do that.

Hi,

I need to use a german authority website in context with firefox (68.10.0esr) to transfer data to the authority. After putting in the data and choosing a ZIP file for upload, a app (java) should open. This is a governikus secure software to confirm my identity by using a card reader and a trustworthy ID card. But the java app doesn't start. I use java 8.251. I have removed all popup blockers. The versions I use are recomended by governikus. I tried this with the microsft IE11 as well, doesn't work ... Could the problem be java sript? I have to activate it but I don't know if it is activated and I don't know how to activate

I hope you deliver the solution ;-)

I have read the public documention on mozilla docs. But it doesn't work. I still cannot learn how to build the SpiderMonkey JS Engine successfully. I try to contact your developer but failed. So I write a forum here. Please help!

I am using Multi-Account Containers, and am unclear on how it interacts with the other cookie and storage management features of the browser. If I clear cookies from Preferences -> Privacy & Security -> Cookies and Site Data -> Clear Data, does that clear all cookies in all containers, or just in "No Container"? Is there a way to delete/manage cookies within just a single container? Is there a way to delete/manage cookies for just "No Container"? Is there a plugin to help with this, or a manual means of editing cookies (editing text file or sqlite database)?

I need to remove the 'CTRL K' shortcut for the Focus Address bar for Web Search! This shortcut hides a very important pgAdmin 4 shortcut!

Thank'you!

I used to love Firefox. But now I am going to delete it. Every time I sign in there is another update! Enough already. The program works fine --- LEAVE IT ALONE!

I received a FireFox update today and lost all of my bookmarks. I tried to sign into Firefox Sync using my work email and I couldn't remember my password. I tried to reset it and when I get to the screen to enter the new password, I get a warning that says Undeliverable Email. I've tried multiple times to reset it and no luck. Any ideas on how this can be resolved?

Every time when i try to use YouTube and google in Firefox i get the error massage "secure connection failed" and the code is :PR_END_OF_FILE_ERROR". This is very annoying issue please help me to resolve the issue
