The website commonly used by Arizonans to make filings for court, will not work properly with Firefox, even after turning off Enhanced Tracking Protection. I had to use Chrome instead.

Hello everyone,

I’m experiencing ongoing problems with Firefox and hope to get some help or clarification here.

Main issue: I’m unable to sign in to my Outlook / Microsoft email account using Firefox. The login page does not load correctly, or the sign-in simply fails (Error 400). When I use another browser (for example Microsoft Edge), the login works without any issues.

System information:

Operating System: Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032)

Firefox version: 147.0.3 (64-Bit)

Additional problems: Besides the Outlook login issue, Firefox has recently become more problematic during normal daily use:

Text selection with the mouse often does not work correctly

Clicking and dragging to highlight text is unreliable or stops working

Pages sometimes feel unresponsive, (ChatGPT)

Overall, the browser feels less stable than older Versions on Windows 10 22H2

These issues seem to be getting more frequent over time and occur on multiple websites, not just Outlook.

I switched my system to Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032) in the hope of improved performance and stability.

What I have already tried:

Clearing cache and cookies

Disabling all add-ons/extensions

Testing in Private Browsing mode

Restarting Firefox

Unfortunately, none of these steps resolved the problems permanently.

My questions:

Is Firefox fully supported on Windows 10 IoT Enterprise 2021 / LTSC for the long term (until 2032)?

Are there known issues with Microsoft / Outlook sign-in specifically in Firefox?

Are there known stability issues (text selection, mouse interaction, page responsiveness) in recent Firefox versions?

What settings or troubleshooting steps are recommended to improve stability?

Thank you very much for your time and support.

Best regards, Marco Klecker

The most recent update has caused an issue with LinkedIn. The problem only occurs with Firefox, not with Chrome or Edge. Do you know what it is? How to fix it? The profile photos are being overwritten with the name of the person and title.

Is there something changeable in Firefox that would allow things to display better? On Tue, Feb 3, 2026 at 11:27 AM Douglas Flegal <toemeister@hotmail.com> wrote:

Answer: Thanks for flagging this. We’re aware that some parts of the newsletter may not display correctly in Firefox, while they do load in other browsers. Unfortunately, this is a browser-specific issue and not something we’re able to control on our end.

For some reason there appears to be an issue between my gmail account and Mozilla/Firefox. When I delete an email, the email below it is also deleted, then I have to dig it out of the trash. It doesn't happen with every deletion, but almost all of them. It's been going on for a few weeks now and is most annoying. Any suggestions for how to cure this issue? Appreciate any help you can provide! Linda

I cant get Pandora to load with Firefox . I am in Mexico and have been using the Browsec VPN to listen to Pandora and all of a sudden it stopped loading. I get the blue screen with Pandora logo but it doesnt go past that. Pandora works on Edge with the same VPN Browsec .

I have an issue where Confluence stops working after a while.

The issues are as follows:

• Opening a link will work and show the page.
• After about 5 seconds, the page will turn black.
• Using the search bar does not work, no results show.
• Trying to expand items in the sidebar does not work.
• Clicking on a link in the sidebar does work, but it too will turn black after the same 5 second delay.
• You can't edit pages.

I have found two ways to temporarily fix the issue.

• Clear the cookies for Atlassian.net.
• Go into the inspector, switch to the Network tab, tick "Disable Cache" and reload the page.

Unfortunately, this only fixes it for a week or two until it comes back.

This is not specific to any one Confluence instance. Once one stops loading, all (that we have tried) stop loading.

Uploading/posting files via the Firefox browser on my laptop to Instagram does not work. It's been stuck on this window for 15 min (I'm using another PC for other work). The only reason I need firefox is to do this action. I don't want to use IG's mobile app for anything. I don't want to use any other browser because IG has me flagged with other browsers — they included my previous IG account in it's random ban via it's AI clean up of accounts for simply posting photos of surfers at a competition —( but that's for another topic for another day).

Any assistance with this will be greatly appreciated. Thank you and have a nice day! —Steve
