Firefox Support Forum

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Recently installed a "cleaner" app called PrivaZer. Ran the app and rebooted as part of the process which also included creating a restore point. Once system rebooted and logged in, pinned tabs were gone?! Using the created restore point did NOT restore the pinned tabs. Is there a way to recover the pinned tabs? Thanks in advance. FRANK

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I have 2 soundcards on my iMac, (OS Ventura 13.6.1) : one internal (iMac) and one for music production. (universal audio)

Until the latest update (127), I could select either one and I could hear the audio from Firefox. But... since the update, only the internal iMac audio card is working. Note that I don't have this problem with Safari nor Chrome and it used to work on Firefox until the last update.

Anyone has noticed that? 

Does anyone knows how to contact them and log this as a new bug?

Thanks all!  :)

For a few months now, I have been having issues with Firefox and my computer audio. If I am listening to something, like internet radio (doesn't matter which website), the audio will completely cut out. Sometimes it will start working on its own and other times I either have to force quite Firefox or completely restart my computer. When this happens, no other audio works on my computer. I have had a new motherboard, audio card, speakers all replaced under warranty. I've also re-installed Windows and it still keeps happening. Has anyone else experienced this? Can anyone recommend a solution?

Issue Summary: When using a maximized Firefox window with the Windows taskbar set to automatically hide, the taskbar sometimes fails to appear when moving the mouse cursor to the bottom of the screen.

Steps to Reproduce:

• Set the Windows taskbar to automatically hide.
• Maximize the Firefox window.
• Use Firefox normally and intermittently move the mouse cursor to the bottom of the screen.

Expected Behavior: The Windows taskbar should appear when the mouse cursor is moved to the bottom of the screen.

Actual Behavior: The taskbar does not appear consistently when the mouse cursor is moved to the bottom of the screen. This issue is specific to Firefox and occurs frequently, though not every time. The taskbar functions normally with other applications.

System Information:

• Windows Version: Windows 10 Pro 22H2 x64
• Firefox Version: Firefox 127.0 (but happens at least since 126.0)

Additional Notes:

• The issue has been occurring for several weeks.
• No specific pattern has been identified regarding when the taskbar fails to appear.
• This issue significantly impacts the user experience as it disrupts workflow and navigation.

Steps Taken to Resolve:

• Checked for and installed the latest Firefox updates.
• Restarted Firefox and the computer.
• Verified that the taskbar behaves normally with other applications.

Request: Please investigate and address this issue in a future update. Any guidance or interim solutions would be greatly appreciated.

Thank you for your attention to this matter.

Windows restarted to update and all my 100s of tabs are lost (setting me back days of work!)... Firefox is set to always reopen previous tabs, but it didn't work. Recently closed tabs/windows are blank. The Restore Session page - about:sessionrestore - doesn't restore and lists no previous windows/tabs. I went into my sessionstore-backups folder and grabbed a previous.jsonlz4 that has some data but am not sure what to do with it.

Please help! This is a devastating loss of information, as I use my tabs as a to-do list and had many in-progress projects with resources that I cannot all recover just through history.

Hello

I am using firefox 126.0.1 (64-bit) version of firefox on a linux system (kernel 6.6). Firefox is closing the main window abruptly (or crashing).

Wanted to get information on the crash, but when I navigated to the about:crashes page, it return a page with title "invalid URL" and the page says "Hmm. That address doesn’t look right."

Is there a way to get to the crash data/information?

Kind Regards Riza

Websites say that my Javascript is disabled, but I already checked on the about:config website and the javascript.enabled is set to true. What do I do so these websites accept that my Javascript is enabled?

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

On many online forms, Firefox substitutes a dash " - " when I type a "9" . I cannot figure out why or how to override this. I am runnning Mac OS 10.13.6 (high Sierra)

I've been using Rightmove Professional on Firefox for ten years plus but now suddenly it's not working correctly as the viewing windows no longer slide. Rightmove say it's due to an update by Firefox and advise to switch to Chrome but I really don't want to - will this issue be fixed? Thanks

I get the following two error messages when I click on Foxfire. Couldn't load XPCOM; and Entry Point not found; followed by this:  ?Nan@Decimal@blink@@SA?AV12@XZ could not be located in the dynamic link library...

I tried to uninstall the program, but got the same two messages and it would not let me. I downloaded a new version and I'm getting the same messages. Everytime I start my computer, I get the same two messages and have to click out of them to keep going. I've installed another browser, but at this point, I just want to uninstall Foxfire so it stops popping up with error messages all the time.

Anybody know how to resolve this? Thanks.

Hello,

After updating Firefox to version 127.0, I started having problems with the playback of some media files. In particular, audio files with the .wav extension do not show the playback time and the file cannot be played. I can play the same media files in previous versions of Firefox and other browsers (e.g. Chrome) without any problems.

Since I think the problem is caused by a browser update, I would like to ask for your help. If you have any solutions or feedback on this issue, please share it.

Thank you.

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.
