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

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

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.

www.blu-ray.com not opening. i tried all ways like uninstall, re-install but still it's not opening. but in chrome and ms edge it's working properly. i tried troubleshoot mode, clear data but still it's not working. it's happening in these few days ago

Turn off tracking, even put x.com as an exception and it still won't let me log into X. Other browsers will but not firefox. I have noticed login problems on other sites too.. even with it " off" ie: IT DOES NOT TURN OFF. Windows 10 system

Ever since upgrading to Tahoe 26.5.2 I've had issues with the way the screen and some forms work:

• some buttons/ icons don't appear
• some buttons appear but don't work (no response when you click on them)
• oddities like if you select the edge of a window the cursore ocon stays as an arrow rather than changing to a resize icon.
• the overall screen appearance is white making some information hard to read

I suspect this is more to do with the Tahoe upgrade than Firefox - e.g. the 'liquid windows' mean some folders change appearance; sometimes being transparent therefore you can't see them anymore. Anyone else experiencing odd/frustrating behaviour since Tahoe upgrade? Seems another case of too many 'clever' features with no value make the software too complex and fragile.
