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,

I constantly used the auto fill for credit cards, but went to pay for something and it didn't auto fill so I went to settings and there is no auto fill section under privacy and security?? WTH??

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?!

On a Mac, OS 11.7.7. When I have right-clicked with my Apple mouse on an link in a website page, I've been shown the option "Open page in a new tab". That option has just disappeared on me, unless I simultaneously press the Control key. What can I do to restore that function (without simultaneously pressing Control)? Even if you cannot answer my question, it would be helpful to know whether the problem is in a Firefox setting or an IOS setting.

I'll be most grateful for your help. Thank you

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 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?

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.

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?

For the last few weeks, Firefox freezes up occasionally. Sometimes, I have to Force Quit to get out of it as Quit Firefox won't close the program. Using Ventura 13.0 on a M1 MacBook Air. It was happening before Ventura as well. Fairly recent issue.

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!!!

I have just installed the Window Titler add-on for labelling Firefox windows.

As soon as I did and as soon as I completed the step in the customise page to add Titles to windows (tick bottom left box), I have lost the functionality to select any of the overall standard Firefox Menu options across the top: everything from Firefox to Help are visible as per normal, but I can only actually click on 'Firefox' to make it do anything. File, Edit, View, History, Bookmarks, Tools, Window and Help are all there still but are unclickable - nothing happens on any of them.

I can click the hamburger menu on a window toolbar and select menu options there. But the overall one is as above. How can I get it working?

duplicate of /questions/1433030 thread.

I‘m somewhat uncertain: I downloaded the Firefox Installer from (I believe) Mozilla.org via Edge. When I tried to Upload the file to VirusTotal I got errors first and it only worked after restarting the laptop.

The file hadn‘t been analyzed so far (which surprised me), 1 out of 72 scanners claimed to have found a Trojan but what bothered me more was that according to VirusTotal the file was compiled in 2018 with Microsoft Visual C/C++ 12.00.8168. It was also somewhat smaller than the last Installer I downloaded (342kb vs. 390kb), although both should be version 18.05.

So I‘m a little concerned if the downloaded file is legitimate?

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.
