Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

Hi Had some problems with the computer. According to Microsoft the dll error was caused by the new Adobe acrobat. Trying to fix this problem some of the websites in Firefox are having now problems. EXP. Kohl's Error code: SEC_ERROR_REVOKED_CERTIFICATE. Home Depot Oops!! Something went wrong. Please refresh page. This is only happening in Firefox with Windows 7, Firefox version 115.33.Oesr 64 bit. When I access these two websites on Chrome in the same computer everything is fine.

What is causing these errors in Firefox????? Can you please help!!!!!

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

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.

Since changing to a new internet service provider, I can no longer print form Firefox. My internet router uses the same username as password as my previous router.

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

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

Whenever I open a new firefox page externally, such as from the system tray or by opening a link from outside firefox, nothing happens for about five seconds and then it loads normally. When I open a new firefox page internally, such as from file ---> new window or by clicking a link within firefox, it loads instantly like normal. This has been happening since yesterday (3/13/26) evening.

I have already tried all of the following fixes and none have done anything:

Clearing firefox startup cache running firefox in troubleshoot mode running an older version of firefox disabling all my extensions disabling my antivirus disabling hardware acceleration disabling captive portal detection making sure both firefox and windows 11 are fully updated refreshing firefox reinstalling firefox rebooting my PC disabling IPv6 preventing accessibility devices from accessing my browser clearing my cookies

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

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.

javascript contains the following code:

var txt = "<tr><td" if (SecIndent[i] > 0) txt+= " class='In" + SecIndent[i] + "'" txt+=' onclick("' +'go2('+ "'_" +i +"')"+ '")>' +SecNames[i] +'</td></tr>' alert(txt) // txt += ' onclick("go('+"_'><a href="#_'+i+'">'+SecNames[i]+'</a></td></tr>' document.write(txt); }

seems to be working right -alert displays: <tr><td onclick("go2('_3')")>Chapter 1 – The Number Tiles</td></tr>

when I inspect element it shows <td onclick("go2('_3')")="">Chapter 1 – The Number Tiles</td>

where did the extra =" come from? when I tried other browsers still problems but inspect element was different hopefully this isn't a Windows 10 problem, but very wierd if it is

I read the existing articles and followed them, starting with "manage bookmarks". When I click on restore, there is a list of the last 15 backups by date. EVERY one of them results in an error message "unable to process the file".

Manually searching for bookmarks.html or json, resulted in nothing found at first. Then I discovered the path to the bookmarks folder were all hidden folders (after the 'user' folder). I got them to display in file explorer ('show hidden files' selected) and tried to manually select the JSON files that way, to restore bookmarks. That also did not work, resulting in the same message depicted below.

Please help
