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.

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, 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

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~

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!

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

If you experience horizontal lines appearing when scrolling after installing firefox possible fix is finding layers.acceleration.force-enabled and set to true after going to about:config in your address bar search for this and set it to true. My real question I ask myself is, why isn't this enabled by default when installing firefox? I swear I remember doing this last Win 11 install as well. My third time installing windows unfortunately, just had a nvme ssd drive fail on me. 😭😢 Ofc, it had to be my Gen 4, C: drive with my old User account on there as well. :// Lesson learned, always backup important data frequently as desired. :( Oh well, just lost all my saved games and few songs, no big deal I guess.

No idea what the cause is but I cannot download ANYTHING on my browser for some reason. Pictures, documents, executables, browser extensions. Tried downloading documents from email attachment.. fail Tried downloading VLC... fail Tried every default recommended solution, clean install, you name it. Mind you all of these files downloaded just fine perfectly via Microsoft Edge.

Noticed another abnormality. Changed the download folder to a custom one. Download failed and DELETED the folder for some reason.

Everytime I open Firefox a new window opens suggesting I add the AVG extention, when I do I get a notification that AVG does not support that extention for Firefox. Why is the nonsupported extention being recomened

When I use Yandex.com, search results appear for a fraction of a second and then page goes blank (please see screenshot).

It is not a Yandex thing, since I can access Yandex search in Chrome. Also, as you can see from my screenshot, although I use Adguard VPN it is disasbled for Yandex.

This is new behavior. I already tried clearing the cache

PS: There was an old locked thread reporting disappearing search results about three years ago but the person asking for help said if he hovered his cursor he could see links. Nothing happens when I hover the blank page. It appears to be genuinely blank. Thank you.

Firefox's DNS over HTTPS is preventing my access to 2 websites I've used for years for booking golf tee times. The 2 sites are www.roosterrun.com and www.windsorgolf.com. I want to remove this feature and return my PC to it's previous settings. Please help. John Blevins bold text

Hello, I am using Firefox for my company. We are using Quickbase system to access the data from internal server. Previously, I can allow Firefox to show the image that classified as unsecured context. I could see the setting option to allow unsecured pictures. But now I changed my account on my computer and when I use firefox, I can not see the image file from server and also I can not find how to allow unsecure picture. Is there way to set to allow unsecure stuff from Firefox? Please let me know.

Thanks

Daniel
