HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP! Thanks friends :) When I try to open this website, nothing happens, nor an error, sometimes in certain website it keeps retrieving and thats it.

Many thanks,

For the last two months I am unable to use a Classmates.com webpage that I have been using for 15 years. It suddenly keeps giving me the following error message Secure Connection Failed

An error occurred during a connection to www.classcreator.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

I have contacted the company and they keep telling me it's my connection or browser and they can't help me. I know there is probably one setting that somehow is wrong but I can't get anyone to figure it out for me. I have tried everything possible. Can this be a browser setting that will not let me edit anything on this webpage? I can edit on other pages that are basically the same type of program ( reunions for schools) PLEASE HELP. YES, MY SECURITY CERTIFICATE IS PAID UP AND ACTIVE.

I am a biomedical research and need to log into the login.gov site to manage my grants. However, access to this site is blocked in Firefox but works fine on Chrome. I'd rather stay with Firefox but will switch to Chrome if this can't be fixed. Thanks, Claire

Hello there - I have the Ghostery free ad blocker installed, but this morning there was a problem and it is not working. When I try to go to the Ghostery hub, I get a message "File not found". I have restarted my computer, Mac iOS, 12.6 Monteray, quit and reopened Firefox several times, and the same message appears. I really like the ad blocker! What's going on and how can this be fixed?

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS

I can't get Firefox to store bookmarks on my Mac since I installed Monterey 12.0.1. I managed to find some instructions on your trouble shooting page but they do NOT work. Hate to give you guys up, but unless y'all can help me fix this, I'll be moving on.

HI, I have just got a n ew laptop and setting it up from scratch. I have logged in to Mozilla, and I was under the impression I would find my password, browsing history and bookmarks there just like it was on my old laptop, but alas not. Ibhave trie looking for a solution but can't find anythjing that helps me out. I have also changed the password just in case it was that but it wasn't. Any advise on this thanks. Would ghate to go back to Safari. I am using Apple M3 MacOs 13.5. Thanks Anna

My wsj.com suscription loads the main, then briefly shows some of the content before dissapearing with this one line Application error: a client-side exception has occurred (see the browser console for more information). Using an older Mac that can not be updated to the latest IOS and wsj support said that Apple made changes so I can't load the contents..... any suggestions or solutions? thank you

I have Firebox as my default browser, both on my iMac and my PC laptop. Problem is, when I click on a photograph on line, it loads the image fit to the screen, instead of its original size! How can I change the setting on both my devices so this won't happen?! When I use Chrome, those images are all loaded in their original, large size, but not when I use Firefox! WHY?!!! I have tried the Firefox settings but can't find a solution! Thank you for your help.

I'm using a 2021 macbook air and cannot find a way to change the font size of anything in the Firefox toolbar. Not the bookmark folders in the toolbar, url address bar or tabs. The default is a microfont that is hard to read for some of us. The old add-on is no longer useful, and one other suggestion I was able to find involved changing the settings in configsys. That is an absurd solution for someone not familiar with changing code or intimidated by the process. I'd love to know if there is an easier solution that I'm missing here. And if not ...why?!

I am running on a mini Mac, OS v, 12.6.2. I have activated the extension (add on) for EZY Photo, but don't know how to get access to edit photos. I've checked in my Mozilla Firefox preferences and the extension is activated. I have not set the extension to private. But don't see a EZY Photo tab on my home page nor do i see one when i open a program like Preview, Photo Booth, Photos, Google Photo. Any suggestions on what I am not doing right?

I purchased ID Resolve but there is no Add On for it that I can find. It only seems to work on Chrome & Safari which I do not want to use. The online software is running "Iris" and works well with Chrome, but I prefer to use Firefox, please help.

I have been trying to attach Excel files to my emails on my MAC but they cannot be opened by the recipients. How can I get my Word and Excel files to be opened when I attach them?

I own an Intel-based Macbook Pro using iOS 10.11.6, on a 2.4 GHz Intel Core i7 machine. Which version of Firefox can I download and use on this machine. 16 GB ram and 15 inch, late 2011 model?
