Firefox Support Forum

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,

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'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?!

Français Language Pack by Mozilla Firefox

Installation aborted because the add-on appears to be corrupt.

Download and install Password Manager as an app or as an extension for your browser.

Ancestry is blaming Firefox for the inability to view DNA matches on their site. Is this true? are you working on it? Do you want me to dump Firefox and use Google Chrome as Ancestry suggests?

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?

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

Just recently I can't print out emails that have information I want to use from the computer. A box pops up that says a pop-up may be blocked. I didn't think an email is a pop-up. Help!!!

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

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.

My bank requires Firefox version 104 now to log-in for security. I have an older Mac, running IOS 10.9.5 (can't update any further) and Firefox 78.15.0. Am I stuck buying a new Mac?

I cannot download Amazon assistant. It says I have to install firfox to get it, I already am on firfox but can’t find to download. If I go to Amazon it says the same thing I must download Firefox. I had the same problem with chrome.

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?

Up until about a week ago, I could use Office 365 (and namely Outlook 365) without any issue. Then a few weeks ago, typing on firefox (MacOS) misses keys, space's don't work, and there will be a random new emails that will open. There is nothing under the keys, nor is there anything under the control or space buttons hindering use.

When I drag/drop or try to upload a file, it won't attach to the email. When force closing, the attachment issue might (keywork might) remedy itself for a minute, but then returns.

The above issues only exist on Outlook 365 on Firefox. I do not have any of the issues when on Chrome or Safari, not any of the apps on my macbook.

Feels Firefox specific due to no issues elsewhere (including while typing this!).

Thanks for any help!

/edit moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section since you mentioned macOS.

Since my upgrade in Firefox my home page when I open it fills only half the screen. I can enlarge it but that's a pain in the rear. Every time I go out of Firefox and then return to the home page it is half the width of the computer screen. How do I get to make the full screen my default? Thanks Richard

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.

Hi, I need to download Firefox 78.0 for my Mac OS X Yosemite version 10.10.5 but I can't find it. Can you please help me, letting me know from where to download it? Thanks, Ro
