While you can disable event listeners in developer tools, the site may still load them later during use. Is there a way to prevent them from loading or at least automatically disable them as soon as they load without using developer tools?

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.

I cannot access sites such as my live.com email and Facebook because it keeps saying wrong password, and even when I try changing the password in the Password section it will still not work.

I have just updated to 145.0.1 and i have some passwords saved as exceptions, so I do not have to log in every time... They are saved still but it is still making me sign in, does auto fills but i have to sign in and go through security checks.. They are saved in exceptions... Also tabs are not opening in new window still , since the last 2 Firefox updates. Are working as they used too in other browser.. I would love some help please. A running Win 11 updated from 10

Not sure I picked the right subject. Bookmarks is what I want to talk about. My bookmark files are all gone!! Am I going to get them back or what? What can I do to get them back? I really need them!

Since some of the updates, now the tabs aren't scaling vertically, and it is very annoying for me, because I used to just click the highest point of the tab to access it, but not I just hit nothing.

Is there a way to make it full height as for smaller screens?

Bookmarks open in the same tab, as they should. But history choices / sites from the browser history always open in a new tab far away from where I'm at the moment.

How can I set it to open in same tab, as the bookmarks? Open in a new tab next to the current tab would also work.

Hi

I need to block some sites through the OS Hosts file, Other browsers ( Edge, Chrome, .. ) are honoring the HOSTS file rules but Firefox bypassing them !! , I disabled the DNSOverHTTPS and all other available suggestion and options but still not honoring the hosts file !

as you can see in the attached file, the Firefox DNS Section is now blank ! but still doesn't follow the OS host file

I even made a custom policy file but still doesn't work, these are the things I disabled but still not working :

{

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": false,
     "Locked": true
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 5,
       "Status": "locked"
     },
     "network.dns.native_https_query": {
       "Value": false,
       "Status": "locked"
     },
     "network.trr.uri": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.bootstrapAddress": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.exclude-etc-hosts": {
       "Value": true,
       "Status": "locked"
     },
     "network.dnsCacheEntries": {
       "Value": 0,
       "Status": "locked"
     },
     "network.dns.disableIPv6": {
       "Value": true,
       "Status": "locked"
     },
     "browser.fixup.dns_first_for_single_words": {
       "Value": true,
       "Status": "locked"
     },
     "keyword.enabled": {
       "Value": false,
       "Status": "locked"
     }
   }
 }

}

I tried replying to your email introducing the new version to report this, but the mail daemon replied there was no mx record for domain=mail.mozilla.org. Have I been scammed by someone appearing to be Mozilla ?

Hi Mozilla team! I have a problem which started happening recently, or at least I didn't realize it before. I went through all the articles, tried adjusting density in Customize Toolbar, went through all the settings with systematic approach with ChatGPT, some things in about:config and even tried adding userChrome.css in profile folder but nothing helped.

The problem is that I have PC with dual screen setup, one is 1440p, 125% zoom in windows settings (main) and 1080p, 100% zoom in Windows settings (secondary). When I change both screens to same zoom, everything is fine, but when it's set up like this, on secondary monitor (1080p one) tabs in open browser don't reach top of the screen, in fullscreen mode, that is, I need to move mouse downwards if I want to middle click open new tab or close old one or even simply move between tabs. It's like, it doesn't reach top of the screen for few pixels - it has a ghost gap.

I don't have this problem in any other browser, tried Chrome, Edge... I would like to continue using Mozilla, but this is bothering me. Could you please consider fixing it in some of future releases?

Thank you in advance!

As a senior why is my FireFox changing I dont know how to get it back to what it use to look like all my book marks are not here on my desktop

I am not a tec person I just want the same as it was!

Please help I have bills to pay

Not long ago I was able to enter "manage data" in setting's search window to then manage specific cookies. Is this no longer possible? If it is, where's that setting located?

FF ver 145.0 (64-bit)

Thank you,

jim

When I am on a website that I want to save to my bookmarks, I click on the asterisk at the top right of the website, select a folder from the bookmarks menu and click on "Save". This used to add the required website to the bottom of the selected bookmark folder so that I could easily use it again at a later date. This no longer works. I go through the procedure but the website does not appear in the bookmark folder. I have seen related questions and answers but not exactly the same and would be grateful for any assistance.
