Diễn đàn hỗ trợ Firefox

I have written about this before, but the problems have multiplied. I've been keeping track of all the sites that I can't access in Firefox, and over the last month or so alone, there have been 23 instances of this. Not only not being able to access actual websites, but other connectivity issues. Several examples:

First, my local newspaper e-Edition comes up in a huge format that is unreadable and cannot be made smaller. It works fine on the Brave browser.

Different example: My daughter sent me several different links over a few days on Facebook Messenger to Amazon products that I wanted to buy. Her message is there, but the link/photo isn't. This renders completely normally on Brave.

Some other examples are restaurant menus listed on the restaurant's website, a Word Search puzzle from the L.A. Times, financial websites in which I have accounts. The list is seemingly endless. My last attempt to get support for this problem did not lead to any fix. This all occurs whether or not my adBlockers are turned off.

As a Firefox user since its inception, I don't like having to go to another browser, but the situation has been getting more and more untenable.

Hello,

I'm troubleshooting a Firefox Desktop issue that I haven't been able to reproduce consistently in other browsers.

I use a browser-based precious metal calculator that performs calculations instantly using JavaScript. The page loads correctly, but after changing several input values and navigating between tabs, Firefox occasionally continues displaying an older calculated result until I perform a hard refresh (Ctrl + F5).

I've been able to reproduce the issue consistently using this scrap calculator scrap calculator. The page loads normally, but Firefox sometimes continues displaying an older calculated value until a hard refresh is performed.

The page itself loads normally, and there are no visible JavaScript errors in the Browser Console. However, the displayed value sometimes does not update immediately after changing the weight or purity inputs.

So far I have tested:

• Firefox Troubleshoot Mode
• Disabled all extensions
• Cleared cache and cookies
• Tested a new Firefox profile
• Disabled Enhanced Tracking Protection for the site

The issue appears only in Firefox Desktop. Chrome and Edge update the calculation instantly under the same conditions.

Has anyone encountered similar behavior involving JavaScript-driven calculations, form inputs, or page caching in Firefox?

Are there specific Firefox settings or diagnostic tools I should check to determine whether this is related to caching, page state restoration, or another browser feature?

Thank you for any guidance.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

Since Thursday, Aug. 6, I have been unable to open my earthlink inbox on Firefox. I keep getting the filled-in login page. when I click to sign in, the login page returns. This does not happen on Edge. I uninstalled and reinstalled Firefox, but that didn't help. I also rebooted my PC, which also didn't help. How to fix?

can not log into https://gallowayprecision.com/ When attempting, there is a sight verification window, it passes, no errors, but once at the sight, I can't get any of the sign in, cart, place items or anything to work.

Edge works fine. Tried all I can think of, still no access using Mozilla

Since update I can't copy and paste, because the menu is partly deleted. Since Update Geocaching.com doesn't work properly. Can't copy coordinates

After clearing my cache, I got logged out of all of my accounts, and I can no longer sign into Google. When I enter my username it gives me a message that says “Couldn’t sign you in: this browser may not be secure. Try using a different browser.” I was able to log in using Chrome so it’s definitely not a device issue. I already tried clearing my cookies and cache again, and disabling all of my browser extensions, but I’m still getting the same message. Any help is appreciated!

Editing to add, I'm using Windows 11 and Firefox version 153.0

Hello,

Noticed a random problem over the last few months with Firefox currently running Mac OS 13.7.8 and Firefox 153. Problem started a few version back with Firefox.

I use gmail while viewing emails in FF I will click a link, tab to review information and I receive ---

Looks like there is a problem with this site 400 bad request. site could be unavailable or busy try again later.

I then proceed to another browser on the machine - Duck Duck, Chrome, Safari and ever browser connects fine, so the problem lies strictly with Firefox as there is no problem with the connection.

I saw a few items to check on the internet but none resolve the annoying issue.

Can anyone advise a solution before I decide to move to another operable browser.

Thanks, Bob

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

Following is what I see on the screen:

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.
