When I try to exit the fire fox browser I delete all cookies then select exit and close it out. However when start my computer the next time I get a message that fire fox is already running and if I hit the cancel button it freezes the screen and I have no options to move on. So how should you do a normal shutdown off the browser?

Hi, When I click on a link in ANY email, it says " Hmm. We’re having trouble finding that site. We can’t connect to the server at omxj86ebb.cc.rs6.net. If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I know I did something to make my computer more secure, but don't remember. Please help! THANK YOU!

I use Firefox for genealogy research because it always keeps track of which pages I've previously accessed since their hyperlink will change color. Today, I ran Microsoft's PC Manager software and it suggested clearing the cache of Chrome and Edge. For some reason it also must have cleared the cache of Firefox since the previously accessed hyperlinks are no longer a different color. Since I had a created a restore point this morning before installing PC Manager, I restored the system to that point. Following the restore, Firefox would not open so I re-installed it from the website. I had previously backed up the profile folder and so copied that to the new profile folder of the fresh install. My bookmarks and history seem to be fine but I still don't see a color difference in the previously accessed hyperlinks. Any suggestions on how to get them back would be greatly appreciated.

The last few days I am unable to load websites that I regularly use. I get a cannot find error message. I have no clue what is going on. I turned off the vpn but that had no effect. This is really hindering my getting things done. Anyone with insight? I cleared the cash and cookies and all that, rebooted the browser as well as the desktop. Thanks

I get why the domain is highlighted, and it's good! But the rest of the URL can be hard to read, especially with dark themes (see screenshot, taken of this page's URL bar, using the default Dark theme). I have tried to find a dark theme with better contrast, but haven't had any success.

Is there a setting that I can change to set the font colors or contrast between them?

My firefox broswer is starting super slow since the last update. I am on a windows 10 lap top running McAfee anti virus software.

In my task manager there are multiple firefox icons running. See the attached screen shots.

I copied one of the crash report into the note section below.

If any one know show to correct this slow start up pleas let me know.

Thank you Dale

Hi, I use Firefox as a primary browser on multiple PCs, so want it to remember a couple of addresses & payment methods for easy daily useage. However, I also access one business domain & when using that website only, I don't want Firefox to offer/remember/anything when it comes to addresses (which will be customer addresses) or payment details (again, for customers). Other autofill, like suggestions for some form fields would ideally still work.

Is there are way to make one domain exempt from address & payment saving/retrieval?

Thanks.

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

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

YouTube playback freezes for a second or two every few minutes.

I have a recording with the Profiler that includes the stutter. It shows a memory drop and some "jank - event processing delay" just before the stutter happens 1m52s in: https://share.firefox.dev/4rzMNyD

My system: Firefox 147.0.3 (64-bit) Win 11 Home, version 25H2, OS build 26200.7840 Processor: 12th Gen Intel Core i5-12450H Graphics: NVIDIA geForce RTX 4060 Laptop GPU

While transferring data from the old profile manager system to the new one, I accidentally created one more profile than I needed. I have tried to delete the extra profile on multiple occasions, it won't go away. I have attempted to delete it through the profile management ui, and I went into the files and delete the associated data. On both occasions, the profile remained in the UI. I am unable to edit anything about the profile either. Is there anything I can do to resolve this annoyance?

I moved and my moving company had my computer soundly packed in a box. After 2 months I have hooked it up. Tried to open my Firefox and the message stated the file is corrupt. I've opened a new Firefox account. Can I get my old account back or can I get my old information into my new account?

Up until a few days ago I was able to preview yahoo mail attachments (e.g. PDFs) before downloading them. I don't know what may have changed, but I don't recall doing anything on my end. Any suggestions or advice on what settings I should consider changing greatly appreciated. M
