Firefox Support Forum

On my Mac Book Air 2015 there is no About Firefox in the Help Tab. So I can't see a current version of Firefox and other features from About Firefox. Also some addons are not working properly (Spoof Timezone for example) and I think that there is some connection between these issues.

I cannot hear a sound on my speakers, only on my headset if connected. This problem doesn´t appear in edge browser.

Can´t find a solution!

Please answer in moderate English, I am not a native speaker, thanks

Since Facebook forced me to switch to new layout a few months ago, Facebook on Firefox (fine on Safari) does not scroll At All (goes about 2 cm beyond first page). Everything else seems to work fine. However, it's basically not usable on Firefox - can see part of the first post and that's it - 'yer stuck' (quite frustrating). Thanks for any/all help.

Hi, I have been having trouble remaining logged in at the Youtube website. I go to the Youtube.com main page and click "Sign In." It logs in using my Google account. However, if I click on any video on the home page, I am logged out again. I have tried signing in and signing out of Google. I tried clearing my cache and cookies. I also used the "Refresh Firefox" option in Firefox settings and I still have the problem. Is there any way to fix this? Thank you in advance. I am using Windows 10 for my OS.

When viewing a video powered by a Brightcove player, the playback control bar on the bottom does not hide when entering full screen mode. I have tried moving the mouse in all areas of the screen, play/paused it with the spacebar/mouseclick, and tried several other methods but it simply does not want to disappear. An example of a website that uses the Brightcove player is the IPL website. You can click here to access one of the videos on the site.

I have tested this with other browsers and the playback control disappears as it should when entering full screen so it seems to be some issue with Firefox. I recently contact Brightcove support and they were not able to replicate the issue on their version of Firefox and just recommended I use a different browser. But it would be really helpful if someone could help me fix this strange bug.

Thank you.

For some website, such as 少数派 ， support both the dark and the normal mode. My Windows system setting is dark mode, so in Edge, this website deliver a dark theme, but in Firefox, it always display a normal mode----white backgroud and black text, I have tried reinstall Firefox, try other edtion of Firefox such as the Nightly, but none of them make help. What should I do? Thanks!

"When a server requests your personal certificate" my preference is set to "Ask you every time" but Firefox is remembering the certificate I used last time for a site and does not allow me to select a different certificate. How can I change this please? My Firefox browser version is 84.0.2 (64 bit). Thanks

Just yesterday some common redirect sites like adfocus and adfly stopped loading in nightly. example: http://adfoc.us/serve/?id=27122877684764

I'm guessing this was done fore security reasons as most people would fall for the fake downloads (or sometimes the entire page redirecting to a new tab when clicked anywhere on it), but it would be great if an option could be added to allow it to load like with: [hey cor-el ask for the link since I don't want this post to get removed :P]

since if you know what you are doing you do eventually work your way to the correct download even if it involves inspecting > deleting the invisible buttons covering the page...

There might already be something in about:config to do it so if so please let me know.

I bought a Logitech web camera to use with my laptop, It works with some websites and does not with others. In the cases where it doesn't work the laptop camera works. Why is this and what can I do to fix it so the Logitech camera works all of the time? Thank you in advance.

For some time now (at least a year), I've noticed that the colors in videos are slightly off. The problem never affects still images, just videos (on every site).

Most users wouldn't notice the problem as it's quite subtle, but all the hues are all slightly off: Reds are slightly more yellow than they should be, yellows are slightly redder, blues are slightly more cyan, and cyans are slightly bluer.

I don't use other browsers so not sure if this is a Firefox problem or a wider problem.

I don't have Flash installed so (presumably) the videos run in HTML5.

Hello,

I want to use browser synchronization. Our network is very limited. What are the domains and/or IP addresses that we need to allow? Thank you very much for your help!

Mac 10.15.7. FIREFOX 86. Groups of bookmarks are gone. This happens regularly. Bookmarks I rebuild yesterday, that group is gone today.

The bookmarks are "there" but not in their group.  Takes hours to re-sort.

It takes a LONG time to rebuild from HTML backup. The jsn backup is ok, but it wipes everything I have done today out. I backup almost every day.

I have thousands of bookmarks = hours of work. Then I have to spend many hours rebuilding. 1/ What is happening? 2/ How to stop it?
