can anyone tell me if this is really that easy? It should be. for instance, I ran a test by creating what you see in the attached image.

and it imports just fine, and in the correct place, however, the actual bookmarked URLs in the 2nd sublevel near the end do not show up. Can someone tell me why? I tried to add these tags in there:

ADD_DATE="1603960941" LAST_MODIFIED="1604177937"

however, that did nothing either. I even tried it by inserting all the garbled junk into the appropriate place, that FF inserts when exporting a BM file. no luck there either. oh, and by the way, I'm not a black hat. I do not buy corporate software. I do everything on my own. Any help here folks?

Hello. I have always been able to have my WinLiveMail open whenever I clicked a mailto link on a website. Recently that function stopped working. It still works on another laptop, but not mine, so I'm guessing some setting changed, but for the life of me I have no idea what it might be. Running Win7 Pro 64 and the latest version of FF. The general>applications>mailto is set to Windows Live Mail as it always has. I changed it to GMail and it works. I changed it to FireFox and it opens the window offering choices, but it won't open WLM. PopUps is unchecked but I can't figure why it's not working. It used to. Worked for years, regardless of the version of FF running. All the add-ons and extensions have been disabled and FF has been run in Safe Mode and it still will not open. Any suggestions would be greatly appreciated. Nothing I find when I 'Google' the issue is helpful, and most of the posts are years old. I downgraded FF to an earlier version and all that did was cause my profile to disappear and really mess up my saved configuration. Fortunately I backed up the old profile and just renamed it to the new one created by the re install of the latest version and all my stuff came back. Just a side note as to what happens when I do click the mailto link, regadless of the site. The top menu banner flashes as I click it and that's all. Not other movement or screen changes whatsoever. Thanks in advance for any suggestions.

A number of functions have gotten a lot worse with the update. One of them is the help function. A lot of the help sites describes the old Firefox version, and if I choose the most updated version, the help files still describes the old version.

And a remark: And its very annoying that we cant reach the company for issues like these. Instead they hide behind these forums, handled by other users who have to take all the heat from us disappointed users. Thats not user friendly. And how well protected are we when the company dont want to have a dialogue with us users?

Problem One: 1Password extension not working for me. I installed Firefox and made it my primary browser. Extensions have been a disaster for me. First I tried adding the 1 Password extension. I did this because when I tried opening a page from 1 Password uninstalled on the browser, it didn't l as it should (has always done so with Safari). I had to open 1Password separately, and copy the information, which is tedious.

So I installed the 1Password Extension on Firefox. It didn't work unless I'd opened the desktop version of 1Password, it still didn't open and fill.

So I removed the extension. I then decided to give it another try. The extension shows up on Firefox. But now it has a little lock on the icon. The problem is that clicking on the icon doesn't open anything! I've rebooted the computer, and only reinstalled the 1Password extension. The same problem occurs, then, without clicking on the problematic icon, I reboot the computer again. It hasn't helped.

PROBLEM TWO: I'm having an additional problem with extensions. When I click on the extension for Pocket (for instance), the program opens, but fails to recognize that I have a paid subscription, asking me to upgrade. This is true for other sites I have subscriptions to, limiting me using the "free" version, which limits what I can open as well as what I can save.

It sounds unbelievable, but that's what's happened to me. I'm using enhanced tracking protection for all sites. Macbook Pro ; Catalina OS 10.15.7 (19H15) - most recent version Max OS

I appreciate any help you can give me. This is way over my head! I've tried everything I can think of, except for uninstalling and reinstalling Firefox.

We are using it for many years and we are installing upgrades and security updates (It is not public application so I can't give you the name). It have possibility to generate certificate request and import signed certificate so we are doing this for many years, with success.

I use a couple of different browsers, Firefox and Brave. I have several profiles set up in Firefox depending on specific sites or groups of sites that I can open individually or together simultaneously. One of these I set up for a recipe management site I use https://recipesage.com. I set up a profile for recipesage and then go to the site, log in and save that page as the default. I then set up a .desktop script in my ~/.local/share/applications folder (I use Ubuntu as my OS of choice) to open that profile along with an image for recipe sage so I can save the "application" to my launcher separate from the regular Firefox icon. It worked fine that way for years until just recently. it no longer works. I deleted and recreated the profile, open it, set the default page, close firefox and restart it and it just spins, never loads the page. If I set the default to the default firefox page and then go to the site manually it works but not if I save it as the default. I have had to switch to using Brave instead which is fine but kind of sad that I can't use Firefox any longer. Any ideas why it all of a sudden broke?

I often experience situations on Firefox where I lose all of my important tabs which I never end up getting back, despite having 'restore previous session' turned on. For instance, it happens when a software forcefully opens a "Thank you for installing" site while Firefox wasn't running, or when I accidentally open a link in a new window while being on private mode, when I meant to open it in a new private window instead..

On a different browser I used before switching to Firefox, I used to resolve this by going to it's profile location and looking at two files named "Current Session" and "Last Session". I could just rename the "Last Session" file to "Current Session", and all of my tabs would return. I was hoping Firefox would have something similar, but it seems either impossible or maybe just a bit more complicated, since I cannot find anything regarding this on the web.

Each time this happens to me, I go to my Firefox profile folder but cannot really find anything regarding sessions I could replace and restore. Only thing I managed to back up from the various important tabs I lost were six files in a fashion like this:

recovery.jsonlz4, upgrade.jsonlz4-[a lot of numbers]

Can I use these files to recover my lost tabs somehow, similar to how I used to do it in the different browser? Hopefully I'm understandable, it's a bit complicated to explain for me.

Is Firefox at risk from an Adrozek Malware attack? Are our passwords that are stored by Firefox safe? What actions do we need to take to protect ourselves from this Malware? Will Mozilla be providing an update to the Firefox browser to address this security risk? Are all platforms at risk (e.g., Windows and Android version of Firefox)?

This sounds very serious. I'm hoping there will be a rapid response to this threat if Firefox is vulnerable.
