Using a Mac Monterey 12.7.6 and uptodate firefox.

Trying to use "tree style tabs". I'm trying to drag and drop a tab named "CHILD" to a tab named "PARENT". Instead of appearing in the tab PARENT the CHILD tab disappears and its content is added to the PARENT tab.

I would prefer the child tab to nest within the parent tab.

Thank you!

How do I answer this request? I cannot find any "ad blocking".

I am all of these popups on Firefox. They say trojan virus detected, malware, detected. It's on an on. How do I stop this? all of the popups say Mozilla Firefox on them. I uninstalled Firefox and the next day reinstalled it. Same problem. I use Malwarebytes and it doesn't stop it. I don't have this problem on Chrome

Hello,

I had a fresh windows installation and so I had to install firefox again.For addictive reasons I use a site blocker to block certain sites: https://addons.mozilla.org/en-US/firefox/addon/block-website/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

But it didn't work anymore. So I thought maybe it is something in the add-on, but I thought I will try another one:

https://addons.mozilla.org/en-US/firefox/addon/leechblock-ng/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

But this is also not working, so maybe there is something changed within firefox or something ? Or does anybody know how to get it working ? Using the latest version 150.0.1

Thanks in advance

I am a long time Chrome user but decided to give Firefox a try for various reasons. 1 like Firefox's ability to highlight and add text comments to articles and documents. One feature lacking, or maybe it exists but I have not discovered it, would be the ability to copy and save all highlights / commnents in an article / document to subsequently use them as a summary, abstract, or digest of main points To preclude having to re read the entire document again And that's wanting to do so. There is a Chrome extension called Highlighter that Does just that , supports the copy all highlights.

Is anyone monitoring this community? Has it been abandoned?

I've been having an ongoing problem. I fixed it myself, because after posting here, I had zero responses and didn't know what to do, so I messed around and tried things on my own, which seemed to fix it. But apparently, it is not fixed, and I still don't know what to do. A Firefox expert I am not.

Very simply, I use two different computers, each 2000+ miles apart. Each time, and this has worked for well over 3 years now, the entire computer is copied to a backup. The backup data is restored, the current Firefox profile, as well as the Firefox program. To repeat, this has worked for well over 3 years now.

In order to get the extensions working, that requires disabling and then reenabling each one. (Otherwise, Firefox will not access the internet.)

This time, the extensions were disabled and enabled, and everything appeared to be working fine, but nope, not a single extension works. Even choosing a different extension that is normally disabled doesn't work.

I used to use Adaware, which is on the disabled list, so I disabled the non-working Ublock Origin and enabled Adaware, and it doesn't do anything. The ads roam freely all over the page. They pop up and dance around.

Not one extension will work. New, old, enabled, disabled, whatever. Nothing.

Does it bear repeating that I am not a Firefox expert? Without an answer from someone who knows what they're doing, I may as well switch to crap, inferior Edge with the zillions of dancing, pop-up ads. And I hate Edge.

I'm begging for an expert to help here.

I want to know why DeTrumpify has been blocked. I use it to block Trump because he is toxic and I don't need that in my browser. So now the very tool I use to block all that hate has been blocked for being hateful? Mozilla, grow a back bone already! And leave my extensions alone! I'll decide what is hate on my device. I don't need a scared corporate nanny to do it for me. Pathetic. DO BETTER!

Running Firefox 150.0.1 64 bit on win 10 Have down loaded Box, Thunderbird pro and dropbox but still flags non verification Have disabled antivirus etc and set xpinstall signatures to false but no change.
