Firefox Community Forum

Buongiorno. Non mi partono i filmati nei vari siti ed, a esempio, anche le dirette RAI, appare una schermata vuota con la X in alto a sinistra. Non so quali impostazioni posso variare. Su altri broserw (tipo Edge) i filamti e le dirette si vedono. Cosa posso fare? Grazie.

I was in the process of writing a somewhat lengthy response and went to another webpage or webpages and when I went back to the webpage where I was writing the somewhat lengthy response, the webpage was completely blank! The Back and Forward buttons were grayed out, Refreshing the webpage did nothing so there was NO way to get the webpage back. Interestingly, when I hover over the URL, at the end of the URL for the webpage, it had "about:blank." Things like this are very frustrating and waste a lot of my time.

In addition, another problem I reported on 3/20/25 (link is: A webpage I just closed recently is not listed Back arrow issue) has still no response.

Also another frustrating thing about the Firefox browser is that at times the Bookmarks sidebar disappears.

I need a reliable browser, not one that sort of works! I request that these issues be addressed soon.

I use the email server fastmail.fm inside the Firefox browser on a 2023 Macbook pro. In the main everyday pane (the list of emails) there is a right-hand scroll bar. Frequently that scroll bar is MUCH too long, so that I cannot scroll all the way to the bottom of the list of emails. Both Apple and fastmail.fm are pretty sure they are not responsible. When the scroll bar is too long, I know a work-around, but I would like the problem not to happen.

I am using a Mac and have just upgraded to Sequoia 15.3.2. When I try to download apps from Adobe It tells me my browser does not work. I thought it was because I was using Mojave but obviously that is not it. Is there something I can do to download apps from Adobe?

So I decided to test out the online, browser-based version of Copilot, and it refuses to work with the microphone even though I have the browser set to allow it. It keeps giving me a page saying it needs to refresh. What am I doing wrong here?

Hello, Any help would be tremendously appreciated! Can someone please tell me very briefly the steps to switch from the FF 128.8 ESR version to the latest supported regular version, which I believe is FF 136. From my research, it appears that you can download the regular version and go to about:profiles to switch your profile back to your original one used w the ESR version. Please list the very simple steps (1,2,3 etc) to switch from ESR to regular version for a non techie.

My background, I have an older MacBook Pro mid 2015, which had 10.11 installed (El Capitan) and recently took the plunge & updated to Mac OS Monterey (12.7.6), which was the highest allowed for this older MacBook. The new OS is awesome & fixed so many websites that were no longer working.

Firefox automatically moved me to the ESR version at some point with my older Mac 10.11 OS. I believe my latest supported version was 78.15 ESR. When I recently updated my MacBook OS to Monterey 12.7.6, Firefox updated automatically to 128.8 ESR.

Now, many websites recently seem to be broken (gmail, yahoo calendar, duckduckgo, & others), so moving from ESR to the most recent regular version seems like the best solution (I believe FF 136 is highest supported by Mac OS 12.7.6). Please list the very simple switch steps or point me to an article. Thanks very very much.

I spent a ton of time perfecting my Firefox, making it look exactly how I wanted… but there’s one huge problem. My entire setup relies on userChrome.js, and I haven’t found a way to make it run permanently without pain.

I’m completely out of energy trying to fix this. But maybe someone here knows a proper workaround?

No js loaders and other hacks worked, so I’m sharing the full code. Maybe you can help me figure out a way to keep it running consistently?

Here’s my code:

function fixTabOrientation() {

   let tabbrowserTabs = document.getElementById("tabbrowser-tabs");
   let arrowscrollbox = document.getElementById("tabbrowser-arrowscrollbox");
   let newTabButton = document.getElementById("tabs-newtab-button");
   let peripheryBox = document.getElementById("tabbrowser-arrowscrollbox-periphery");
   let navBar = document.getElementById("nav-bar-customization-target"); 
   let urlBar = document.getElementById("urlbar-container"); // Адресний рядок

   if (tabbrowserTabs?.getAttribute("orient") !== "horizontal") {
       tabbrowserTabs.setAttribute("orient", "horizontal");
   }

   if (arrowscrollbox?.getAttribute("orient") !== "horizontal") {
       arrowscrollbox.setAttribute("orient", "horizontal");
   }

   if (navBar && urlBar && !urlBar.nextSibling?.isSameNode(tabbrowserTabs)) {
       navBar.insertBefore(tabbrowserTabs, urlBar.nextSibling);
   }

   if (newTabButton) {
       newTabButton.style.position = "absolute";
       newTabButton.style.right = "10px"; 
       newTabButton.style.top = "50%"; 
       newTabButton.style.transform = "translateY(-50%)"; 

       if (peripheryBox && !peripheryBox.contains(newTabButton)) {
           peripheryBox.appendChild(newTabButton);
       }

       newTabButton.style.display = "block";  
       newTabButton.style.width = "32px";
       newTabButton.style.height = "32px";
   } else {
       console.log("New Tab");
   }

}

fixTabOrientation(); setInterval(fixTabOrientation, 1000);

Any work solutions would be massively appreciated—I’m honestly exhausted fighting this.
