Firefox Community Forum

I have just re-installed MW due to probs using the original one, but now I cannot enter my registration code,(life time) there is no where to do so it seems,have looked everywhere?

How do I stop Firefox from opening Finder in a new window? I don't want to have to go back and forth between windows. The same thing happens when I open a PDF. Thanks.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

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.

Over the past few days (Oct. 18, 2024) the green Download button has been missing. When can we look forward to the fix? Have uninstalled & reinstalled twice. Thanks.

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator

Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.

Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.

And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.

Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.

So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?

Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator

Thanks for your assistance! Steven

Yesterday I have updated tp macOS 15. Sine then I have trupuble displaying any webpages in Firefox 130. Th econnection just times out. Any other browser such as Brave, Safari, Home, Edge are still working as before teh update. How to fix this please?

The bookmarks icons and fonts are too small for my older eyes on my new Ubuntu computer. They are bigger on my older Ubuntu computer. I have tried to find out how to enlarge them without sussex.

I am aware of the Zoom feature for a webpage itself, I am not asking about that. I simply want to have my bookmark toolbar FONTS and ICONS larger.

This has been frustrating. Perhaps including an EASY way to do this for future updates, or an app suggestion that would solve the problem. Thanks for your consideration and (hopefully) help.
