Firefox Community Forum

I am using the Firefox browser on my iMac. Suddenly, I am not able to 'sign in' or access pages of common websites. I am getting blank pages or pages with the ever-circling ball when trying to access websites, like homedepot.com, shutterfly.com, etc. I can access them via safari.

I have gone through the Troubleshooting steps, have Uninstalled Firefox and Reinstalled, etc. What is happening with my browser?

Hello

When attempting to pay for online purchases the new firefox upgrade (Mac 133.0.3) will not redirect from the merchant to the payment site. Yesterday, before the upgrade, was no problem making credit card purchases online; now, nothing. Please advise on how to set up new firefox version to allow redirect to payment websites from merchant sites.

Thank you.

We have two Macbook Air computers, both using Firefox. On one of them the cursor no longer works on a particular website. Both laptops have Firefox 301.03.

The website tech help said Firefox was not compatible with their site but the problem is only one of the computers. What could be causing the problem?

I need to enlarge the font on the bookmarks toolbar as I have a visual impairment. I can find ideas for the regular toolbar, but not for the bookmarks toolbar...oh, and I am working on a Mac.

Thanks in advance for any help.

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.

I have just installed Firefox on a new iMac, running MacOS 15.2. Firefox will not load any of the websites I have tried, whereas Safari and Chrome do. I have cleared the History and also set "No proxy" but loading still fails.

Hello,

I have an old version of MAC Os El Capitan 10.11.6, which new version of Mozilla can I install to respect new security standards ?

Thanks for your help

I want to know whether I can update my current Firefox version with my very old desktop setup. I am using the Firefox browser version 78.15.0esr (64-bit) on my iMac 2007 running OS X El Capitan. This notice came up when opening Firefox: " Your version of Firefox will start to have problems on January 14. A root certificate will expire, causing some preferences and other features to stop working. On March 14, 2025, add-ons and more features will also break." Following the instructions to update, in About Firefox window, it checks for updates and then shows Firefox is up to date. I've interpreted this as there's no version available that I can update to. Is that correct?

Hello,

I have old 15 year old mac el capitan -10.11.r with outdated firefox 78.15.0esr 64-bit.... in perfect condition. Unfortunately I can not make updates on browser anymore. Online banking websites does not allow me to use this outdated browser. Would you be so kind to make even paid update for me? Or at least let me know what settings I should change under about:config

When printing the same page repeatedly, FF gets increasingly slower and slower each time until it is downright ridiculously slow and takes up to a minute, perhaps more, to get to the print menu. However, if you reload the page, printing is instantaneous (at least for the first or second time). Some history or memory management problems?

FF Version 135.0 (64-bit) on MacBook Pro Sequoia 15.3.1

One test case would be https://api.razzlepuzzles.com/cryptogram. Keep selecting New Game from the pull-down menu on the right and try printing as PDF (or anything else).

Hi, I was wondering why my cursor cannot be placed properly on the place, take a look at the image, the cursor needs to get lower in order to properly placed on the right window,

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

The other day I discovered all my extensions have been disabled. I have an old Mac and am not able to upgrade to a newer version of Firefox. Is Mozilla going to offer a solution for people like me who find their preferred browser to now be frustrating and inefficient? I would love to restore my add-ons. Thank you.

So, I just now installed Firefox and now I want to change the background of the home page (new tab), the same way you would do in chrome. I did some research and created a chrome folder and a chromeContent.css file in there.

I tried first the code in this link: https://support.mozilla.org/en-US/questions/1271362 and then this one: https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

neither of those worked, even though I'm pretty sure I followed all of the instructions correctly. help please, will be greatly appreciated (i don't know if i chose the correct topic)

pictures included in order: the code (device name crossed out), inside the chrome folder, inside the profiles folder
