Firefox Support Forum

When expanding any video to full screen mode, the video does not occupy the entire screen. However, if Firefox itself is in full screen mode, then the video will occupy the full screen.

I tested this on YouTube and another website's video player and was able to consistently replicate the issue.

See image to view the bug in action.

I just made the switch from Chrome to Firefox, and I'm still trying to understand the small differences that exist between the 2 browsers.

While on Twitter, what I usually do is middle-click with my mouse on a Tweet to a new tab that I want to look into later, then continue scrolling down my timeline, then check out the Tweets I opened in the new tab(s). However, when I try to do the same thing on Firefox, it automatically opens the new tab. Because of how Twitter works, this also reloads the Home page when I opened it up, so I just lose anything I was just looking at when I opened the Tweet in a new tab.

What can I do differently here?

Amazon Sign-in problem started on 10-15-22. Amazon does not accept my password and asks me if I would like to receive a text message for verification. There is no yes or no selection displayed. I select resend text and I am given a telephone number for Amazon customer service. I go thru a 15 minute security verification process and Amazon tells me if I do not answer any questions correctly, they will cancel my account. On the 2nd time I contacted Amazon, I was told to use Crome browser and not to use Firefox.

This problem happens with my personal computer (windows 10) only. My Android phone using the Amazon app works with no problems. I can also use Crome browser on my computer and Amazon works fine.

Any suggestions ? Thanks

What about:config option do I have to disable to remove those new buttons from the address bar?

Firefox 105.0b2

I suppose the other question is why did you add them? There are already three places I can get at that information.

Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab.

Do you have any idea?

I'm working on version 105.0b2 with two profiles on an ubuntu 22

I don't know what this is, what it's called, or why the someone in your UI/UX team continues to think that it's a good idea to change the keyboard navigation in the browser with all these new, special, or whatever controls that are ultimately useless.

How do I turn this off?

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

As of today, I'm seeing black text on the black background of every site with a dark theme, including Google Search and Github

I'm running Firefox Developer Edition 105.0b8 on macOS 12.5.1. My macOS Appearance is set to Dark

Switching the Website Appearance config setting between Firefox Theme, System Theme, Dark, or even Light does not change the colour of the text

The URL in the URL bar is trimmed. I went to about:config and disabled "browser.urlbar.trimURLs", but it still did not work after I restarted Firefox. (see images)

Firefox version: 105.0 (on beta update channel)

I later then found out that there is a lot of unused space on the right. (see https://1drv.ms/v/s!Ag9_47ED3j7sgsZhkB02k7gI3lavyg) How do I remove / make use of the space on the right of the URL bar? How do I turn off the trimming of the URL?

Any help is appreciated!

Today's 105.0 Firefox update rendered my NYTimes Wordle page unusable -- a big empty [ad?] space has been inserted at the top of page, forcing the game halfway down the page (https://www.nytimes.com/games/wordle/index.html). The PC keyboard is still connected (I can enter letters in the puzzle grid) but the mouse is not connected so I cannot scroll the page, cannot bring the pictorial keyboard into view.

How can I uninstall the 105.0 update?

Thanks, Gail

Hi, so yesterday, I updated to the latest version of FireFox (version 105.0). Nothing seemed to be out of the ordinary until I decided to watch a few YouTube videos. The best way I can describe this problem is that every time I decide to scroll down to see the description or read a few comments, the entire screen on my laptop goes black regardless if it's on default view or full screen.

Even though that does sound like a crash, the audio still plays, and if I power the computer to sleep mode and log back in, the window of the video automatically scrolls up and everything is back to the way it was (but I did had to restart the laptop once because it also visually broke my mouse pointer). The only way I can get around this problem is to pause whatever video I watch and then scroll down, and no black screen occurs.

I don't know if I'm the only one who has this problem, but I've never had this issue happen in past versions of FireFox. If there is another way to fix this problem, I'll be glad to take anyone's possible suggestions/solutions.

My Firefox (Windows 10) updated to 105.0 this morning. I have https://www.google.co.uk/ as my homepage and Firefox always used to focus on the Google webpage search bar on startup.

Now it focuses on the address bar instead (i.e. https://www.google.co.uk/ is selected). How can I make it focus on the webpage search bar on startup again instead?

I already found this thread from last year https://support.mozilla.org/en-US/questions/1334131 and tried changing browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false but it didn't have any noticeable effect and the issue is still present.

Many thanks.

After several years using Firefox my log in to GMail ceased to work. The address shown (https://mail.google.com/mail/u/0/?pli=1) when I tried to log in produced no response whatsoever. Other websites loaded normally.

I tried Chrome instead and logged in successfully. I have restarted my computer but the problem remains.

The hotkey for add-on "600% sound volume" has been broken since the last version of 103. (now 105.0 still not fixed) The hotkey is "Ctrl+Shift+v", which opens the pop-up window of the add-on, and then it allows using arrow key and number to tweak the volume bar. Now all hotkey not working. The arrow keys do not work even if you manually open the pop-up window.

After opening a new window in Firefox, it automatically enters and selects everything in the address bar. this has been happening since I downloaded the latest update for Windows 10 (64-bit). I can't find any option to prevent this from happening. whatever is happening there, it's not useful to me.

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

When entering a local domain in the URL bar Firefox sends the request to a search engine instead of the DNS server. How can I stop this behaviour and switch back to how it was before?
