My usbank login page doesn't load. Works fine on Chrime. https://onlinebanking.usbank.com/auth/login/?redirect=internet_banking_logon

I have Mac OS 10.14.6, so Firefox stopped working with its latest update. So I downloaded Firefox ESR. I want my passwords, history, and browser data from my original firefox, but when I go to the Import Browser Data function, my original firefox is not listed as an option to import from. And I can't launch my old firefox in order to export the data to an html file. So what can I do? Thanks!

I noticed recently that the "+" for new tab is no longer displayed and available. I have to go to File/New tab to open a new tab.

Does this happen only for me or it is a change that was made? What should I do to have it back as it used to be and it is displayed here:

Thanks.

I am wondering if I am the only one experiencing problems with Firefox with using some websites. I have no choice but to use Safari, which works without any issues when I am encountering these problems with Firefox on a Mac.

My privacy preferences are set to Standard.

Sample websites with issues with Firefox: - substack.com; I could not create an account - paulaschoice.com - I wanted to purchase some items that were in my cart. After I entered all needed info to pay, the button for CHECKOUT just didn't do anything.

Safari had no problems doing the above.

Am I doing something incorrectly?

For years I have used Firefox and every update has been seemless. This one is terrible!!

Every time I click to open a new tab, it opens a new page Every time I try to change tabs from previous to the update, it will not change. I am stuck on that tab Every time a new page is created I cannot open it because it has a "block pop up windows" and this is a setting that I did not change. I have had to turn off all blocking just to be able to change my password, to be able to typoe here.

You have basically stopped my studies until this can be rectified and I doubt anyone will repond to this message

Asked earlier about deleting and doing a reinstall. Would that mean losing bookmarks, profile etc.? I have backed those up and would like to know if anything else might be required.

YoutubeTV is suddenly not working on Firefox, fine elsewhere ... they suggest doing complete reinstall.

I would like to be able to control which OS and version is reported by my browser to sites like https://www.whatsmybrowser.org/ . I can do about:config but I don't see which setting has that info, to change it. I also see a User Agent Switcher extension, but it doesn't let you set the version of the OS. https://www.whatsmybrowser.org/ clearly shows my OS and version, so I know it's there somewhere. How do I change it?

I have a neuro issue where these trigger my migraines.

And they've become standard web design.

I currently reduce layout.frame_rate to 1, which *helps* unsmooth scrolling animation. That's often enough to navigate pages with narrow sidebars, or with good visual contrast between the sidebar and the content. But it's not enough on pages with extra-wide sadobars and no visual contrast, such as Wikipedia's "Vector" redesign, or the Internet Archive's latest redesign:

https://en.wikipedia.org

https://archive.org/details/texts?tab=collection

I can force Wikipedia into mobile, which helps, but I'm not aware of a similar fix for the Internet Archive, and really need a global fix.

I can get reasonable behavior from the Internet Archive if I reduce the window to about 640 pixels, ... but instead of a non-scrolling sidebar taking 1/3 of the screen, I end up with a non-scrolling desktop taking up 2/3 of the screen!

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

I would be so grateful if anyone has a solution!

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I have a good 1080p monitor, which I can set up in either orientation. I have a hard time finding monitors which meet my accessibility needs, so a square/squarer monitor or a 2nd monitor would be expensive.

I have tried setting it up in vertical mode, to make it easier to read pdfs and to write. And ideally, to make it easier to avoid sidebars and/or move them away above the main content where they're less likely to trigger as many @##$% migraines.

I've noticed that most websites are designed for the horizontal layout. Elements disappear off the right edge, sometims with a horizontal scrollbar to reach them, sometimes without. Is there a trick to get miost or all websites to fit?

I use about:config fixes, add-ons, and user css to try to increase font sizes, switch colors, block animation, and reduce frame rates to completely block "smooth" animation. I can't do without these, so I don't think I could adapt the mobile version to my needs.

I've noticed *many* other problems in other apps, but if I can get all these websites working in Firefox, I can probably sort out the other problems elsewhere.

A few days ago, Firefox updated itself. Suddenly, every link opens a new tab that says "Anti-phishing Protection is scanning your link..." and the original tab opens a window that says "Anti-phishing Protection - You are attempting to open an insecure link. Are you sure you want to proceed?"

I cannot find anywhere to turn this off or fix this ridiculous situation?

For the last two days, cnn.com won't load and gives a message that the browser is blocked. Can you explain how I can remedy that? It's a rather popular site, so I assume Firefox will want it to work. All my other sites are working fine, so I'm assuming it some adjustment that cnn made on their end.

Hi, I would like to use my computer's built in print dialog instead of the one that pops up in FireFox. I know there is a button at the bottom of the dialog that allows me to choose my system print dialog, but when it comes up there is no way to view the number of pages like when I print from other apps.

I tried to use some online instructions using about:config, but it doesn't change anything. I would like to know how to turn off the FireFox dialog permanently. It only started happening in the last few FireFox updates.

I am running a 2010 Mac Pro in Mojavé and am using FireFox Version 115.11.0esr (64-bit). Please help. I need to see how many pages I'm about to print so I can decide which ones I want to actually print.

Thank you,

Jeff Hohner

I use Spanish/English dictionaries. I also use Web sites in English and in Spanish. I want spellcheck to detect the language and enable the proper spell check. I always had that ability in Safari, for example.

Necesito ayuda! You see; it doesn't work.

Thank you for any help!

I've been noticing a consistent issue specifically with Firefox causing my mac to black screen/shutdown involuntarily.

It happens specifically when I use the zoom-in function on firefox web pages (the pinch zoom).

Other times when it doesn't black screen, firefox would sometimes have this pixelated appearance (basically random squares interspersed around a web page at times) after I try zooming in.

Anything I could do to help prevent this problem?
