I have Firefox set to use the built-in .pdf viewer to avoid Adobe's intrusive AI features. I have disabled Adobe's AI features in the Acrobat settings, that does not seem to apply when Firefox opens the Acrobat reader. Consequently, I have to fight off AI "suggestions" and offers of help when I simply want to read a document from the web.

So I set Firefox to use the built-in reader. After 1-2 seconds, it switched to Adobe, and brings up all the annoying AI features. How can I keep Firefox from switching to Adobe?

As a test, I renamed Acrobat.exe to AcrobatX.exe. Firefox behavior did not change. I also killed all Acrobat-related tasks in Task Manager. My document still displayed in Acrobat after 1-2 seconds, but none of the Acrobat-related tasks reappeared in the Task Manager.

I am using Firefox 145.0.2 64 bit in Windows 11 with all updates current.

Many thanks for advice.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

I noticed recently that my 'Add Shortcut' button has disappeared. I've been through other articles and they were of no help. I have 4 rows selected for shortcuts so theres no reason for it to be gone.

Tonight I was roaming around my Firefox settings looking at something else, when I noticed this AI piece pre-checked. Why is FIREFOX, who is supposed to be for privacy and security, authorizing an update that automatically choose AI? Not cool Mozilla. Not Cool. Anyone else have this? and yes, I've already fixed it ;-)

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

I have downloaded Firefox ESR and think it has been installed on my masOS version 10.12.1 and am wondering if I can use it on this version after reading your warning about support. Perhaps I have not installed it properly as I have just used what I think was the previous version since it has all the oldsaved sites.

Choices? I need to understand the App before committing my internet presence. Options to revert to Firefox/Windows, disable features I choose. Otherwise it just GQQle. Sync is already intruding on my preferences.

Firefox is preventing me from going to certain websites because it is telling me I am using adblocker but I have none installed.. I am trying to play around with the settings but I still can't do it. Is there an inbuilt adblocker? I need help please...

I really miss the home symbol (a little house), as it allowed me to go back to the original page- blank. I could just start over without having to clear the address bar. It was way better than without it. Any way I can get it back?

Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.

This is not the first time you have sent an email to me indicating I should "View all sites where your info is exposed", and each time I receive your emails the sites you suggest are sites I have never seen before, let alone logged into with a password.

I use a Password Organizer Book, with all of my logins and passwords for each site I use. I do not use a password app, and have NEVER used a password app. Each time I go to the website you suggest, It's always a site I have never seen before so it would be impossible to login and change the password. I always check my Password Organizer Book to make sure.

I don't know what you want me to do since I cannot login to the website you are suggesting. Is there action I should be taking? I don't know what it would be, but if you know please let me know.

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com
