Firefox Support Forum

I've confirmed the following problem was introduced in Firefox 57, and continues in v58 and v59b. It does not occur in v56 or prior. It also does not occur in the current versions of Chrome v64 or Safari v11.0.3.

When accessing www.pubmed.gov through a library http rewriting proxy server (ezproxy from OCLC), and clicking a link which targets another web site which has subdomains, FF57 attempts a forced Content Security Policy : Upgrading insecure request. This fails because the proxy uses a wildcard certificate which is invalid for multi-level subdomains.

Screen shot attached.

Firefox is my default browser and I cannot download any attachments in my Yahoo email. I tries to sign into my Firefox account but it would not accept my password. I tried 3 times to do a password reset but I never received a reply to my email address. My email address is: ************@yahoo.co.uk. I had followed the Firefox help suggestions to fix my problem of being unable to open attachments of any format in my yahoo mail and cleared all of the Firefox Cache and Cookies. A blue folder appeared on my MacBook Pro laptop called "Old Firefox Data". Since this did not fix my inability to open any attachments in my Yahoo Mail (New Mail and not Classic or Yahoo Pro), I need help on what I should do. How do I return to my Old Firefox Data and Settings, fix my problem of being unable to open up attachments in my Yahoo Email and fix the problem of Firefox not accepting my account password or not sending me a link to do this? I do not know how to proceed and it appears that many of my settings are changed or gone. Even my default opening page of: https://uk.yahoo.com/ has gone. What do I do to resolve all of these issues. Many thanks, drrjm.

I need to bookmark sites I use a lot and I just updated Mozilla on my Mac so I need to add them to the toolbar, but there is no icon next to the site as instructed in your help page

I'm using Mbpr 2013 with latest OSX, Firefox is Nightly version I already disable all add-ons, uncheck recommend performance settings, uncheck Block dangerous and deceptive content, try safe mode too.. still very slow . I dont know why this happen

I download and get an icon on the desktop and on the bottom menu. If I click on the icon on the desktop, a text box on the screen with two options: "Firefox" and "Apps". If I click on Firefox, the browser opens. If Aps, I go to App Store for no apparent reason.

After 1-2 days, all icons disappear and I cannot find them anywhere.

I updated firefox to version 63.0 but it crashes continuously. I tried all the solutions you suggested. I reseted and restarted it in safe mode but the result is the same. This is the code of the last crash:

bp-65ca3cad-37fb-42c1-9431-a028c0181026

I can not send this request from firefox because it does not work so I have no chance to click “automatically add”

What can I do?

Firefox won't open any links when I search something. I have to go to Chrome or Safari. Just deleted and reinstalled Firefox but am still having the same problem.

This report also contains technical information about the state of the application when it crashed.

My firefox tabs has been crashing, and it has been getting far far worse. Practically none of the tab will open longer than 5 milliseconds. Other browsers works perfectly fine. I tried starting it on safe mode, no good. Tried clean reinstalling firefox, no good.

Can anyone help me why firefox is specifically crashing? About a month ago it worked perfectly fine.
