Firefox Community Forum

Hello, when opening a video on YouTube in full-screen mode, the horizontal scroll bar becomes visible if you start moving the mouse cursor or scrolling. This doesn't happen in other Chromium-based browsers, where the scroll bar is always hidden (in full-screen mode). I tried deleting all browser data, but it didn't change the situation, and I couldn't find any solutions on the forums either. This looks very unattractive and ruins the video immersion. I hope you can help me resolve this issue or release an update that fixes it.

Thank you!

How does one get rid of things like this: ad.doubleclick.net

This is one of several plagues on my PC. Another is googleadservices.com. They appear, hijack searches, making it almost unusable, and I can not locate the app, program, or add on anywhere.

I restarted Firefox and noticed my toolbar book marks were missing. In further inspection, I noticed all my bookmarks over many years are missing. This is obviously a disaster. What happened? Is there way to recover this information?

In AM of 05/23/25 my Thunderbird mail downloaded to my desktop just fine. By afternoon of same day I get an error message (see attached) saying that it is unable to write to my mailbox. Error has continued for almost 24 hours now (thru 05/24/25 AM). I can get the email account on my phone through another program, but I like to save my important mail to my desktop storage. Please advise. (I did nothing to change my Thunderbird configuration on 05/23/25 that would have generated this message.)

I have to do a clean install of Windows, how do I save all my firefox bookmarks and passwords as well as Thunderbird addresses and any other info I might want to import back into Firefox and Thunderbird once I've installed windows again.

every time I try to log in to my hotmail account, I get this: "Please retry with a different device, use a VPN, or other authentication method to sign in. For more details, please see https://go.microsoft.com/fwlink/?linkid=2317517" this has started today...have been using Hotmail and Firefox for years, now all of a sudden this happens? why isn't firefox allowing me to use hotmail?

I was mistakenly logged out of my Firefox account which I used to sync all my data , on trying to log back i did not remember the password of the email I had used, so I clicked on forgot password and went through the process of setting only to find out that I have lost everything. Please what do I do

Since Mozzila updated to 115.23 to x64 Windows there is no longer the abillity to watch Twich live Streamings. Is this going to be permanent ? Should we all leave Firefox after so many years od succefull use and go to Chrome? Are you aware of similar live broadcasting issues ? Wiil Mozzila include a solution soon?

I've explored this extensively. I have a number of locally hosted webservers, mostly wifi routers and the like. I am unable to access ANY of them via firefox on mac. Safari can access them, and firefox on windows can access them, but firefox on mac can't. Also: chrome on the same mac also fails the same way. Trying to add an ssl cert exception in firefox settings doesn't work, after keying the url and hitting the button it also can't access the cert to add the exception with. This is something that used to work with firefox on mac, but at some point mac changed and is blocking both firefox and chrome. Apparently safari was adjusted to match the change, and firefox/chrome simply need to catch up?
