Firefox Community Forum

Looking for a way to configure the "Share the screen" permission present in permissions for individual sites via GPO. I am aware of this doc but I can't find anything for setting this permission. Specifically, to block it for all sites with an explicit allow list.

The "Preferences" option won't suffice as permissions are stored in permissions.sqllite and are not part of the about:config preferences. The "Permissions" grouping lacks... the majority of the possible site permissions as well.

I found this file on my desktop. File type is Firefox HTML Document. Size 1KB. I've never noticed this before and wonder it I should delete it, move it, or what. Anything to worry about? I haven't opened it.

Thanks for any enlightenment you can offer!

hi for some reason twitch.tv or some other websites will no longer play videos on my pc and i have no idea why, firefox works fine on my laptop

Hi,

I was a former IT person for decades and used Firefox because I love it. But lately, it isn't usable for me. Seemingly happened out of nowhere within the past few weeks.

I tried all the troubleshooting steps in the guides on your support forum, but nothing worked. So I tried the following:

1. Uninstalled Firefox using Windows Uninstaller 2. Deleted every single Mozilla folder from within the user profile to the program files folders, local roaming folders, etc. - EVERYTHING. 3. Went into the Windows Registry and also deleted Mozilla folders within the local machine and current user folders. 4. Rebooted computer 5. Went to Getfirefox.com and reinstalled Firefox. 6. Logged into a brand spanking new Firefox installation

Still SLOW as molasses. Frustrating. I can't work. It is literally 4x slower than any other browser now. I use Firefox for 90% of my web stuff, the other browsers 10% of the time for testing. But as it goes now, I cannot use Firefox anymore after decades of using it.

Anything else I can try? Maybe I missed something when I scrubbed it and reinstalled? Why suddenly is it this slow? Any ideas?

I will try next to log into a different Windows profile I guess and see if that improves it. Maybe my Windows profile is jacked up, although, I thought removing all Mozilla folders from within my Windows profile would be enough, so I am not so sure that will fix it. I will try though.

Any help you can provide would be much appreciated.

Thanks,

Mark

Up until 2 days ago, I had no issues accessing my yahoo email accounts (sbcglobal.net through At&T) I had done nothing different re settings. I rebooted my modem and my computer several times. I deleted old history which I do several times a week anyway. I called AT&T support team but they just suggested logging on to another browser. So I tried Edge and was able to access the emails successfully. I even "refreshed" Firefox and nothing changed except I had to replace several quick links. I checked for updates and discovered my Firefox browser is up to date. My Android cell phone has no issues with the emails. I have one on Firefox browser and one with Chrome on my cell phone and no issues with either one. I have been using the same log in link for many years. I even explored the new way to log in called "Currently.com" for yahoo mail. Still won't work on Firefox. But it does work on Edge. I would prefer to continue using Firefox for browser but need to use Edge til I figure this out. Any suggestions would be greatly appreciated. (BTW wifi IS on and the connection for everything else works fine.

All of a sudden, the text in my Bookmarks bar has turned black making it unreadable on the black background. Any idea why this happened and how I may revert the text back to white? Thank you for your help.

Hi,

I have tried to sync between my two computers, but it did not work out well:

e.g when I click on ‘show more bookmarks (>>)’ on the right side of the screen (next to Other Bookmarks) I get - Firefox is not responding and I have to click on

-> Close the program.

If I click on -> Wait for the program to respond - Firefox never responds! And before I click on -> Close the Program - my keyboard input is totally erratic!

This occurs on both computers! - what can I do…..

I have therefor on the computer I want to be on the receiving end:

- deleted: History, Downloads and Tags and All Bookmarks - Cleared browsing data and cookies - Closed all open tabs

And now I am Signed in with Syncing; ON - on both computers again.

But I have not checked any of the check-boxes in ‘Manage sync…’ - ‘Manage what syncs on all your connected devices’ i.e. Bookmarks, Passwords, settings, History, Payment methods, Open tabs, Add-ons

Why is there no check-box tag groups!

What do I have to do on my SOURCE compute and on the DESTINATION computer for - a one way sync of everything?

Best regards, Einar

PS,

After Signing in I was presented with the following, and I chose Not Now

Sync your Firefox experience View your saved passwords, tabs, browsing history and more — across all your devices. Select an option to continue:

- I already have Firefox for mobile Start your sync now if you already have Firefox on your mobile device. 

- I don’t have Firefox for mobile Download Firefox on your mobile device, then start your sync.

Not now

Using Firefox, my gmail inbox is my home page - and has been for several years. As of yesterday, the page opens but the page is blank. I am not aware of any changes that I have made.

I do not have this problem using chrome on the same device or firefox on other devices.

Probably something simple, but I have no idea what.

Thank you

I rebooted and launched FF, I was asked if I wanted to Refresh. Naturally I declined because I'm not an idiot. Now all my addons and passwords are gone. I would love to have them back since I never asked for them to be deleted. I don't have an "Old Firefox Data" or whatever folder on my desktop, would have been cool for them to leave that there when they clobbered years of data and customization because Firefox thinks they should have more control over my PC than I do, but they didn't. Is there any way to get these back?

I can't log into my doctor. Their web support says to not use Firefox.

I've been with Firefox for years. I don't want to change browsers.

Can you fix the communication problem between Firefox and MyChart?

Thanks for everything,

I am having trouble signing into my account ******@gmail.com. I no longer have an authenticator app account and I used all of my backup codes. I do have a recovery key though. I hope this helps in recovering access to my account.

The initial problem I was dealing with was FF kept directing me to Youtube every time I clicked on a NORMAL link in my google search. 🤷‍♀️ I tried several different links but same result....Youtube again!

This is where I went down the rabbit hole. 🙄 My first step was to get some help with my Firefox browser for this 'redirecting' issue. Under the help heading, "More Troubleshooting Information" I found "Give Firefox a Tune-Up using Refresh". Hmmm, maybe this will fix the issue?? I carefully read the following before proceeding....

"Start fresh to fix performance issues. This will remove your extensions and customizations. You WON'T LOSE ESSENTIAL INFORMATION LIKE BOOKMARKS AND PASSWORDS."

WRONG!!! MISLEADING!!! LIES LIES LIES!!! 😡😤😡

I lost almost ALL of my saved bookmarks except for TEN (the most recently used) that still remained after the refresh was completed! I literally lost over a hundred of them that I had accumulated while using Firefox for so many years!! 😲😣🤦‍♀️ 21 different folders, Home, Travel, Shopping, Banking etc, each containing 10-30 OR MORE bookmarks to sites I need to SAVE to be able to revisit later when needed. ALL GONE!!! 😡😤

I have been loyally using ONLY Firefox as my browser for 2 decades!! Now the only thing I can say about Firefox is a whole lot of curse words!!

WHY WOULD FIREFOX INCLUDE SUCH A #$@&! STATEMENT??? "You won't lose essential information like Bookmarks and Passwords"......YES YOU WILL!!!

This NEEDS TO BE REMOVED!!

Why not be an honest and reliable browser?? Include information that if you perform a refresh, you WILL lose these essentials but you might possibly be able to recover them from hidden files somewhere, but you won't easily know where to find them!! 😉

The next time I have ANY issues using Firefox I won't be 'refreshing' nothing at all!! I won't troubleshoot NOTHING!! I will just copy and save all of my bookmarks and SWITCH TO GOOGLE CHROME!! 👍

For first time received email from breach-alerts@mozilla.com. Title is: Your monthly Mozilla Monitor report. Is this a scam? Other people have asked this question and Mozilla Firefox company has not made any attempt to answer these serious questions. If I do not hear back from Mozilla Firefox within a week I might remove Mozilla Firefox and use another company.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

I believe there was a button to send a url link by email on Firefox. I tried to find that button everywhere, but I still can't find it and it didn't even get to an answer for this by asking questions on Mozilla website. Could you kindly guide me where to find that button?

Thank you in advance.

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.
