Every time I open Firefox recently, and the Yahoo.com web page starts up, I get an annoying prompt from global privacy control, that asks to allow or not allow. IT'S ANNOYING. I went into the settings for that apparent add on feature, that I DIDN'T add, and set all 5 settings to FALSE, but the program still pops up. It ALSO screws up the format of the Firefox web page, and shows the Yahoo News feed totally different and it's also VERY ANNOYING HOW do I totally get rid of the global privacy control? I can select the Firefox settings under security to tell web pages to not sell the info, as far as I know, correct, so I don't need the retarded global add on? ?? I want Firefox news feed like it was before the update. Thank you very much... HOPEFULLY!

The last update did something to my search bar. I still have it, but when I click on it, it moves to the upper left corner, prevents me from seeing my tabs, bookmarks etc. How can I disable this annoying change? If someone has the answer, I would greatly appreciate it.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

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

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

After a windows update I get the following message when I try to open Firefox: The procedure entry point ?ToLogLevel@mozilla@@VA?AW4LogLevel@1@H@Z could not be located in the dynamic link library C:ProgramFiles\Mozilla Firefox\xul.dll Then I get Couldn't load XPCOM

I tried uninstalling firefox but it just hung. I restored it to before the windows update but still got the same message

Is there any Add-on that will shoot a scrolling screenshot (full page screenshot)?

For reference, there's an excellent extension on Chrome/Brave called "Go full screen" which has simple but perfect functionality, one-click automation, saves as either .pdf or .png format to your downloads folder.

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

Hi, I just finished writing a few lines of javascript to automate bookmark management. I tested my Addon using about:debugging > Temporary Extensions, and now I'd like to keep the extension loaded across firefox sessions.

What is the best process for doing this? I attempted to create a .xpi file but when installing via "about:addons > Install addon from file" I get the message "This addon could not be installed because it could not be verified".

What is Firefox's self-signing process for this? I don't want to have to install dev versions of the browser just to automate one task.

I've just been told by my Firefox Browser that there is an update available but it can't install it automatically, I need to manually download the file and install it. It took me to an Enterprise page which gave me the choice between a Rapid Response version or an ESR version. Firstly why an Enterprise page? Secondly which version do I need fora PC running Windows 7 Pro 64 bit please?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

I recently got a new computer, Apple iMac. I'm trying to transfer all my bookmarks I have on my older HP computer to the newer computer Apple. I downloaded the Firefox browser to the iMac. I see where there is a link to transfer bookmarks when I loaded the browser. But, when I click on the link, nothing really happens? There is no transfer of my bookmarks for my old computer to the newer computer. My OS with my older HP was Windows 7. My OS with my acquired Apple is Monterey. Can someone be of help with transferring bookmarks from one computer to another? I have many bookmarks so it would be very helpful to be able to make that transfer. Thank you.
