Firefox Community Forum

For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

I have just logged on for the day and the Side Bar has changed. It now has an extra layer making it wider which now pushes a highly used website page off the screen which is very annoying because I don't want to reduce it's zoom any more.

I use the Side Bar to bookmark various links within this website as shortcuts to navigate it.

How do I remove this unwanted extra layer?

Please find attached a Snipping Tool file.

The unwanted extra layer is the bar down the left showing my Bookmark icon on the top and the Settings icon on the bottom neither of which I want or need and this is causing the extra width to the sidebar which is upsetting my viewing. How do I remove this new bar?

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

I have been unable to complete the update/upgrade of Firefox on my Laptop. Upon starting my computer I have downloaded the upgrade file offered in the opening message. It performs normally right up to the end when it gives a message that something went wrong. It then offers an alternate download and method to upgrade which downloads fine and begins to install. At the end of this install, the install wizard says "finished" however despite the "Launch Firefox" box is checked, it never opens Firefox. For some reason the update is not completing, and now I am having trouble with some Apps opening which I suspect is due to the browser being out of date. I have tried clearing my Cache and Cookies and re-trying but have remained unsuccessful. I really could use some assistance with getting my browser successfully updated. Best Regards, Brian

Today I Receive Mozilla Firefox 133(64Bit) Update. After Successful Update. My Open Tabs Are Not Loading. Also, Firefox Become Very Slow When I Surf Youtube Videos. Video Stuck But I Can Hear Audio. Taking Time To Load Videos. Its A Portable Version.

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

I have the same problems as several others. Bought a new computer and cant get download helper to pin to pin to the toolbar. Have tried hitting the puzzle piece and finding the tab after that for extensions but still cant find how to pin it as it does not give me that option.

Hi,

I just updated my firefox browser. And had numerous tabs that were still open. Usually when I have update it I go to history and click on recently closed windows/tabs and everything comes back on.

But this time, there's nothing there! I'm missing all of the windows/tabs that were opened before. I look in my history tab and there's nothing there either from the time the firefox was updated.

Before Firefox had something called restore previous session. And that's not there either.

Can you please help me get my old tabs/windows opened again? Please

My original install crashed, and kept saying to close, and would not stop.... I tried uninstalling all of Firefox and when I install the new clean version, the messages continue and will not install the application. How do I completely remove Firefox and install a fresh copy?

This morning, I was presented with an opportunity to update Firefox. As always, I chose "Yes". Ever since, no matter what I do, I am completely unable to connect to a webpage. I only get an error message stating that the webpage I'm trying to connect to has crashed. I am offered the choice of reloading only that particular webpage or all crashed tabs. NEITHER option works. It's just a loop that comes back to the same error message. I've used Firefox exclusively for well over a decade. I maintain subscriptions to Relay Premium and Pocket Premium. I have NEVER run into a problem with a Firefox update. They generally only take 30 seconds or so and very rarely involve a download. I spend a majority of my workday online. PLEASE help me get back to the version of Firefox that I had prior to this newest update, along with my hundreds of bookmarks, my Extensions, my Relay Premium and Pocket Premium subscriptions. You can reach me at tjkenning@att.net. I am running the 64 GB version of Windows 11 Home (with Automatic Updates). Thank you.

I recently updated to v130. I'm having the same problem that so many others have, "Firefox already running, close Firefox". After updating to v130 I had to go to Task Manager and delete 19 Firefox running. It's only been a few days ago and I checked Task Manager today and deleted another 13. After updating to v130 many of my add-ons are showing up in the Menu Bar. I have used Add-ons Manager to drag and drop, but it doesn't work. I have specific bookmarks that should be in the "Bookmarks" section" but they are also showing up in the Menu Bar. I had to re-select my screen choice because it had disappeared. I use DuckDuckGo for my search engine and in the past I was able to choose a separate search bar, but that too has disappeared and I cannot seem to fix it in settings. So many problems after updates, but this one seems very bad. I use Windows 10 on my desktop PC

Please Help, Rhonda
