How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

Really annoying with latest update there is no add short cut box on the home page anymore. I use this lots to save time now I have to go into browser history and find the link. All there is now is Recent activity and suggested sights that are picked for me. I don't want this on my browser!!

i got an update message and restarted firefox. now all my saved bookmarks and passwords for accounts has disappearred. how do i get them back? under settings, it doesn't give me option to import from previous firefox

i Creat my new website Fashionlox but on chrome or edge show with www and on firefox open without www like just fashionlox.com any one explain why i face this issue.

Hi, I’ve noticed that Firefox often uses a lot of memory when I have multiple tabs open, even more than Chrome or Edge on the same number of tabs. Sometimes it slows down my system or makes switching between tabs laggy.

Is this normal behavior, or is there a way to reduce Firefox’s RAM usage without losing performance? Are there specific settings, add-ons, or troubleshooting steps I should try?

Thanks in advance!

There's already a decent help article about how to block videos from autoplaying:

https://support.mozilla.org/en-US/kb/block-autoplay

The problem is, it works haphazardly. Even if my default for all web sites is "Block Audio and Video", on some web sites (not all) embedded videos still start playing as soon as they scroll into viewport.

Some have adviced to delve into about:config and set media.autoplay.blocking_policy to 2 (default is 0) and, based on quick testing, that actually seems to help but why exactly does it help? If privacy settings already have a setting to block autoplay, why does that particular configuration change make it work as it is supposed to work?

Running Floorp 12.5.0 (Firefox offshoot) on Win11, if that helps.

Just received message, by LIFEHACKER, originally discovered by LAYER X, about "17 malicious extensions across numerous browsers", the list which includes Firefox and is supposedly a recent event outside of the earlier (?) event involving the Malware Ghost Poster in downloads previously cleansed by Firefox. Is this old news or is there more Malware that is 'out there' or that could be on my computer without my knowledge? (I do not download willy-nilly....) Would appreciate valid insight if it is just repetitious/old info rehashed for shock value. Thanks!

In version 146.0.1, or perhaps even earlier, I noticed that if you set a Primary Password to log in to the browser, you can reset it and log in simply by clicking the "Cancel" button. This allows you to access all of your user tabs and links. I hadn't noticed this before. It defeats the purpose of setting a Primary Password. I noticed similar issues in the Tor browser, but you can't set a Primary Password there at all, even though the feature is there, and it's built on the Fire Fox engine. Please fix this issue. No buttons should allow you to log in without entering the correct Primary Password.

After the last update, I am missing the “Minimize” and “Close” buttons on Firefox on my Microsoft desktop computer. Cannot close the app when finished. Anyone know how I can get them back?

Bank site allows autofill for username but does not allow autofill or manual fill for password. Access to the site worked fine 3 weeks ago. Autofill works with MS Edge.
