I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

Hi, I have a link in my website that opens a file in another desktop program. The link looks like this: openwith://C:/path/to/file, but after update to the latest Firefox version (v122.0) the second colon from the link is for some reason removed, resulting in a path like this: openwith://C/path/to/file. This is a problem because the path it now tries to open doesn't exist. Is this a deliberate feature in the new Firefox version or is it a bug? If it is a bug will it be fixed? It still works fine in v121.0.

I want to disable Norton Safe Search. I followed Inst. Menu, add ons, extension tab, clicked the 3 dots & then delete. Restarted my computer, but it's still there. I definitely need help.

Hello,

I'm seeking help because sound is not working on Firefox. All other software are able to produce sound on every speaker and headphones I have. The speaker logo does not appear in tabs were videos or music is playing and firefox doesn't show up in EarTrumpet. It does show in the volume mixer but no bar appears to show it is displaying sound while media is playing.

I'm running : Firefox version 119.0 64 bits Windows 10 64 bits version 22h2, OS build 19045.3570

I've tried :

1. Restarting Firefox
2. Muting/Unmuting Firefox in the volume mixer, in firefox tabs too
3. Downgrading to version 118.02 32 bits
4. Uninstalling all my audio drivers followed by a restart (they got re installed but no change for Firefox)
5. Restarting Firefox with all addons disabled

I'm running out of solutions.

Kind regards

I'm at a loss here, problem is in subject line. This has happened for a long while and has persisted through various versions, I have attempted to:

- Alter my antivirus and internet protection settings to allow as much traffic as I can. - Download addons as XPInstall files and try and use the File -> Open File option in the Menu Bar - only returns a line about not having permission, despite having Admin permission.

My Firefox Version is the current 118.0.2 (see: attached image).

Thanks in advance.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

All of the files I try to download fail immediately. Even extensions will not download on firefox. I have uninstalled and reinstalled and checked the download location. Downloads work on other browsers such as Chrome fine but nothing will download on Firefox.

On FF 120.0.1 and Tab Reloader 0.6.1

I have FF set up with 7 tabs as home page, 6 of the tabs have tab reloader set to reload ever 1 hour. This has worked fine for years, the tab reload for the 6 tabs were saved after restarting FF. I didn't have to go back and tell tab reloader to reload after restarting FF. Maybe once and a while one tab didn't get the reload saved on a restart, usually always the same one.

Now when I restart FF none of the tabs have saved the setting to reload every 1 hour.

This has been going on for the last 2 releases of FF updates and there hasn't been any updates for tab reloader. Does anyone know why this is happening, I haven't changed anything in settings. I did uncheck hardware acceleration to see if that would fix another issue, but tabs weren't reloading after restart prior to that change on hardware accelation.

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.

The last couple of weeks I have this pop up interrupt my screen quite often several times in a row.

I have searched every article online that is remotely similar to this problem and none of the solutions have  worked. 

Any ideas on what I can do to stop this annoyance?

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

The full website link has /users/login, but when I checked the saved passwords, the link stops before the first /, its just websitename.com, instead of wesbsitename.com/users/login, and I suspect the full link not being save is whats causing it not to show up. Is there any way to brute force it to show up?
