Firefox Support Forum

I was advised to use the Authenticator.cc extension for my Firefox browser on Windows 10 PC, I can't get it to run. It downloads but will not then do anything. I can't get the icon into the menu bar, I can't scan a QR code, it just will not perform. Why not?

I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

Dear Firefox Support,

I am writing to report an issue I am experiencing with Firefox Stable (v.126.0) when attempting to access the URL https://ibb.co. This URL is supposed to redirect to https://imgbb.com, but instead, I encounter the following error:

Secure Connection Failed An error occurred during a connection to ibb.co. PR_CONNECT_RESET_ERROR

This issue seems specific to Firefox Stable, as I am able to access the URL without any problems on chromium-based browsers (Chrome and Arc) and Safari. Additionally, the URL works correctly on Firefox Nightly (v.128.0a1).

I have attempted several troubleshooting steps, including:

   Disabling all extensions
   Using private browsing mode
   Clearing cookies and cache
   Restoring settings to default

Unfortunately, none of these methods have resolved the issue.

Could you please assist me in resolving this problem? Any guidance or further troubleshooting steps would be greatly appreciated.

Thank you for your support.

I am running a Mac Mini with the M1 chip. I recently updated the OS to Sonoma (14.5) from Monterey and find that the type on Linked In is tiny, only about 7 pt. My FF is 126.0. My minimum font size on Firefox is set to 14 pt. If I make it larger, like 20, Linked In is readable, but all my other sites are too large and hard to navigate.

Your automatic reader thinks I'm running 10.5. I've never run 10.5 on this Mac.

LI says it is a Firefox problem, which it is, because the site reads fine on Safari.

I know that there are sites which don't work on Firefox, like Chase Bank, which is a drag. Please don't tell me that LI is another one.

Somebody, please help.

Firefox 126.0 on Sonoma running on my Mac Studio does NOT sync passwords but DOES sync bookmarks. Firefox will not save passwords nor will it load passwords from a .csv file Under Sonoma SYSTEM SETTINGS and PASSWORDS (after entering mac password) shows the website passwords there, but the passwords DO NOT show in Firefox. Restart of Mac or restart of Firefox does not fix this.

I uninstalled then reinstalled Firefox. I was able to recover my bookmarks, add-ons, and login information. But I do not know how to recover by pdf files. Are they gone for good?

Good afternoon,

I am not sure if the topic is the right one I choose.

My question/complaint: recently websites, although mostly websites from my bookmarks, seem not available or existing. Mostly after a few minutes and a new trial, the website comes back as if nothing was wrong. Could it be the last update from Firefox? I never had these "problems" (a big word for minor inconveniences) before and I use Firefox at least during the last 15 years.

Thank you in advance for your answer.

Best regards, Rien de Vos

Hello, when making a purchase on a website with Mozilla, after entering the security code received on my mobile phone, the bank's virtual keyboard does not appear to enter the security code of my online bank. thank you for your response. Sincerely

Hello, Whenever I try to open something on Firefox, for example, the Library, I get the message "Mozilla Firefox (Not Responding) and it hangs with no immediate responsive action. I click on any Firefox button or tab and I get the same message and I get the blue little circle and I sit and wait about 30 seconds or more. The page or tab eventually works but it hangs for 30 seconds or more. It is frustrating. Please help.

Thanks, Tricia

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

Firefox is synced on all my computers. Same version. Same extensions. I can't login on my primary desktop as of last night 5/23/24. I can login/watch Prime on my laptop. My desktop gives me the attached error.

When logging into a Wordpress site on Firefox, hovering over Username displays a gear (see first screenshot) which when clicked on exposes passwords and allows them to be edited (see second screenshot). This does not happen on other browsers. I'm on Firefox 126.0, MacOS Big Sur 11.7.10

Hi guys.

Need some help. I can't download any files using Firefox. It always says, "Failed".

I tried other browsers, and I'm able to download just fine.

I already tried this guide, https://support.mozilla.org/en-US/kb/cant-download-or-save-files, but still same.

I haven't tried to re-install Firefox because I have a bunch of workbook marks that might get lost. So, I want the re-install option as a last resort.

Thanks~

Shoot!! I just filled this out, and somehow, it reverted me back to This screen again!! I am not a programmer or IT Guy. What I am is a person that is Very alert to sudden changes in my experiences. I retired 14 years ago, as a Manager in a Manufacturing industry. Very familiar using desktop. For some reason, about a couple weeks ago, some of my sites have begun using google adds, over and over. When I click on the "X", wants to know why, etc. I use Malware Bytes, scans every day. Does NOT discover any malware, but I KNOW something has changed to allow the bombardment! Is it possible it's just a single site that I had to change and log in to? Even if so, WHY doesn't Malware stop them? Should I try a system restore to weeks ago? I am on here Every day.so I'm pretty cognizant of changes! ADVICE PLEASE!! Bruce Pierce

Thanks in advance for any insight or suggestions. My preferred browser is Firefox. In Chrome, I can easily use a voice search from www.google.com. In Firefox, the permissions show my preferred mic as enabled and selected for that webpage -- but no sound is detected. (Using Firefox. mic works fine at https://www.onlinemictest.com.)

(BTW, speaker output is Realtek motherboard audio and mic input is a Shure X2U USB interface. This mic works just fine in zoom, whereby, audition, etc. as well as working google.com using chrome)

Have worked through various settings in the SOUND panel and SITE PERMISSIONS with no luck.

Any ideas about this problem -- or what other settings to trouble shoot?

Thanks!

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Please approve the update to Twitter X Ad Blocker. I've chatted with AldAstra Labs the creator and they have an update but are waiting on Firefox to approve it.

Thanks, Tracy
