Firefox Community Forum

So I installed the Window Titler add on. First the Firefox main general toolbar menu didn't work, which was fixed by closing down every window and Firefox and re-launching.

Now though when I use Yahoo in Firefox, I can't reply, forward or select ANY of the buttons to action an email. Other buttons work. But if I launch Yahoo in Safari they work.

Problem happened exactly as I installed the add-on. Any ideas what's going on?

- Marquis has colonised my search page. - I used to be able to get rid of it temporarily by going into troubleshoot mode and going through that whole process twice - oddly, it never worked first time. - Now that doesn't work. - I can only get to my DuckDuckGo homepage via my bookmarks, which means I can't have more than one page open at a time. Firefox opens by default in Marquis. - I downloaded paid-for antivirus software with no results, so I'm reluctant to get anything else unless I'm sure it will work. - I notice that several people on this thread and elsewhere have reported this intrusion. - Does anyone know what to do about it??

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.

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

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.

Every time I log into a website, it asks if I want to save the password, and I click save, but it doesn't work. When I go into my account and try to add a saved login, it says "An error occurred while trying to save this password" and at the top a small bar appears saying I need to enter my primary password to log in, despite the fact that I'm already logged in and when I click the log in button it just goes back to the logins and passwords page and nothing has changed. I've tried quitting and restarting, changing all my preferences, nothing works. I've googled everything I can think of with no answers to my issue. Please help or I'm going to give up on Firefox and never use it again!

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?

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 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.

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 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?
