I have organized my bookmarks into various directories & sub-directories. On occasion, these directories &/or sub-directories 'migrate' if I'm not precise with my cursor movements. Is there a search function I can use without having to go through each directory/sub-directory one-by-one?

I use Dashlane as an extension in android Firefox on my Acer Swift GO 16 laptop. I use my fingerprint to log into the laptop but in the security settings in the Firefox Dashlane extension I see the message: "Your browser does not support biometrics. To use this feature, install the Dashlane extension using Google Chrome or Microsoft Edge." I prefer to use Firefox.

Why is the option to use Biometrics (fingerprint in this case) not available?

This is to report that after clearing the cache for eBay.com in Firefox, the site now loads correctly. Please dismiss my earlier reports regarding this matter. Thank you, Chauncey R. Black

I have accessed the particular website many times but today it says, "Hmm. We’re having trouble finding that site.

We can’t connect to the server at shop.naturalcompounder.com.

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 have had this problem in the past, but now its back again. At first I just reset my password every time, then I set up the password to be auto-filled. I have had no sign-in failures for months. At one point i did figure out how to check my sign in history to see the failed attempts, and there were none. That was a long time ago, and I have since forgotten how to check this. The problem does seem to be with firefox as it does not happen with chrome.

I'm trying to move search engine from yahoo search to Firefox search engine because I had the Firefox search engine on my old phone and I liked it because it worked better than yahoo.

Ok, This is a bit of a question that seems to have many answers but none that have ever worked for me. I have in the past 12 months probably formatted my PC 4 times, and I have at least 12 profiles on Firefox nightly, not to mention the rest of the family. It's not really a problem to redo them every time, but it is just a painstaking simple process. If I could just backup the profile folder, copy it move it change it whatever, it would be nice and simple, even to transfer from one pc to another in the house, but every time I try, It fails. Copy the Userdata folder, copy the entire firefox folder, blah blah blah, never can I do it. I believe it has something to do with security that you can't just copy and the entire profile folder, but some way to backup the profiles exists surely? One that actually works. Cheers All!

I receive many unwanted/junk/spam emails a day (10 to 20) in my email inbox. How do I stop this influx of junk? right now I am blocking domains, is this the best I can do?

Hi, I'm running Sierra 10.12.6 on a mid-2011 iMac. I installed Firefox 115.33.0 in March '26, but now see a "not supported message" in the browser.

I downloaded the ESR version of this browser, but when I went to copy to the APPS folder it asks if I want to replace the NEWER one that's already there. ???

Now it says I'm running it on the ESR update channel. Did I just go backwards in browsers? When this ESR expires, if a new one isn't provided then, will I still be able to use/update/install Firefox on this IOS on this iMac?

Thanks! Elaine

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

I have moved my profile to a different location on the hard drive to make backups easier. How do I tell firefox where the profile is now located. c:\users\med\my data\PROFILES\mozillA\*.deFAUlt

Windows 11 : Fix this ASAP I delete all tabs, close firefox, reopen and I get 5 tabs which seem to be STUCK. I delete 3 of these tabs, go about my work, none of those 3 are open, and I shut everything down. When I reopen Firefox, those 5 "default tabs" (the 3 I don't want have migrated over from I don't know were - both Chrome and Edge open with New Tab.)

I have enough other problems in my life - and done't tell me to create a new profile. At that point I'll kill firefox and end my donations to Mozilla.

Hi,

I am trying to synchronise my web browser on my phone to my laptop, but when I try to do so using the QR code I get an error saying I need to use a Mozilla app to do it rather than my phone camera app (see attached)

I can’t find anywhere in my Firefox browser settings this app!

Help!!
