Firefox Support Forum

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

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 use Firefox for going onto AOL and keep getting the message below. Would appreciate talking with someone and even better, getting onto my MacBook Air and help me out. Talking is most helpful. Tim

Hmm. We’re having trouble finding that site. We can’t connect to the server at www.effulgencefoundation.org. If you entered the right address, you can: Try again later Check your network connection Check that Firefox has permission to access the web (you might be connected but behind a firewall)

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 recently got a new Mac, running Ventura. When I did I lost the second toolbar that used to be in Firefox, the one that shows frequently used programs, like Google, Apple etc. Instructions say to click on Firefox and select Preferences, but there is no Preference under Firefox. I tried looking under Tools and got no where. What do I need to do?

Since like 2 weeks, Firefox on my M1 MacBook keeps crashing. This is really annoying which is why I have to consider switching to Brave.

Does anyone have the same problem?

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'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?!

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

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.

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 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.

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 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.

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?

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

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

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.
