Diễn đàn hỗ trợ Firefox

I am trying to 'fork' my FF, duplicating my profile on to a stick, then modify each one so that my work related bookmarks, saved passwords, cookies, history etc are in one profile, and my social/general bookmarks, cookies, passwords etc are in the other. I have done this and using about:profiles can open the non-default (USB stick) profile in a new window, or set the non default profile as default, close, re-open FF into the alternate profile. All good so far. However this isnt working quite as I expected. If I switch to alternate profile, save a bookmark to the shortcut bar, then switch back to the other profile then after a second or two the bookmark I saved in the other profile appears on the shortcut bar?!? This happens whether I have opened alt profile in a new window, or have changed the default profile and restarted FF into the other profile. Is this because in both instances it is using the same local directory? The doesnt seem to be an option to choose a different local directory for the alt profile. This would be ideal if possible as it would ensure that there are no data crumbs left on my PC when using the USB stick profile which is important for my work security. Any help really appreciated.

Error message says: "HTTPS not available on this site" Choices: : "Go back" or "Continue to HTTP only site". If I choose "Continue to HTTP site", the address bar shows that the address is indeed HTTPS! Have I been hacked? Do I have a virus? I can find no help elsewhere. I have saved the error message but, using your "Browse" below will not show it in my documents.

Up-to-date Firefox on Windows 10 laptop. Today, for the 2nd time in a week or so, the “mailto” function has disappeared; i.e., if I click a “Send email” link on a webpage, the Windows dialogue box to select a mail app pops up. When I check the applications setting, mailto doesn't appear in the list.

The first time this happened, I found online instructions to refresh Firefox and select Gmail as the mail client. I don’t mind doing it again, but I am concerned about the problem occurring so soon after the recent refresh.

Why am I getting this message when I try to log in at lowes .com: Access Denied You don't have permission to access "http://www.lowes.com/u/login" on this server.

I do not get this on Edge browser.

When I go to my bank's login site, I get a message saying that I need a newer browser. I have the latest version of Firefox, and I used to be able to log in just fine, but I recently reset my browser and I seem to have lost some settings. I have tried adding an exception for this site's cookies in Settings, and I've also tried turning off enhanced tracker, but the site still doesn't work. Is there a way to tell what is broken and then fix it? Thank you.

I am a visually impaired individual, who is struggling at times to clearly and efficiently see the controls, menus, and bookmarks on the FF browser header/pages. I have adjusted every setting, on my own system and within FF, that I can find and think of. I have the webpages set the way I need them to be; I just continue to struggle with the Tab headers, menus, and bookmarks within FF itself. If anyone can help me, it would be GREATLY appreciated. TIA.

I have read hours of Q&A about this problem here in this forum before posting, and cannot find a solution.

Until very recently, whenever I would click a link in a page, it would "Open in Firefox" in a new tab. Then after reading it or printing it or whatever I wanted to do, I could click the download [Fx98PDFviewer-DownloadButton] button if I wanted to save it, and an Explorer would open up allowing me to select where I want to put it and what I want to call it (if I wanted to change the name it comes with) before downloading/saving.

Now, when I click a link it just downloads (even though most of the time I don't want that). Despite all I've read, I've tried a dozen settings, and I CANNOT get that behavior back.

If I set the browser.download.improvements_to_download_panel to False, and select "Open with Firefox" when it prompts me, I can't get it to STOP prompting me. It prompts me EVERY TIME, even though I have checked the box repeatedly for "Do this automatically for files like this from now on"

And yet it is STILL downloading automatically when it opens for viewing in the new tab, and I am forever now cleaning and deleting crap out of my downloads.

I have my default PDF reader set to the reader I like, and when I'm NOT in Firefox, I do NOT want to have to right-click and select my preferred reader each time.

But when I AM IN FIREFOX, what I need it to do is

- Open in Firefox, in a new tab, 
- DON'T prompt me, just do it, and 
- DON'T download it, unless if I then want to keep it I click the download [Fx98PDFviewer-DownloadButton] button.

HOW CAN I GET IT THIS BEHAVIOR BACK PLEASE?

I know register an account and login both Mac. But looks like they are two different accounts! I confirmed both Mac are on latest FF 103.0.2, I login the first one with my id, register it with my email. Then when I try to login the second one, it is asking for register again! Not login! So they always have different bookmarks. I've tried two id, drhtd@163.com and gyfguo@cn.ibm.com, both can't work, any help is appreciated, this bother me for long time.

Sorry I asked the question in the title. I cannot open links in emails or on websites sometimes. I am using Firefox but even if I paste the link into Microsoft Edge the link will not work. I do not know why and it has only started happening lately - within the last month or so. Any advise gratefully received. Maybe it is my system or settings or Firefox or Bitdefender. I am a techophobe so please bear that in mind when you respond. Thank you

I woke up this morning and my tab bar on Firefox was out of control. I figured out how to shrink the tabs in about:config. However, there is a huge space at the end of the tabs that is completely unnecessary. I've been googling all morning. I tried to find compact mode--but "density" is gone, even when I go back into about:config and enable it. The only other help I found was to change the CSS code and unfortunately, that is outside my wheelhouse.

Is there ANY way I can get my old tab bar back so that the tabs fill the top of the screen as opposed to having a huge empty space at the end?

Why do I get this message in firefox when I can open gmail in Microsoft Edge?

How do I stop the Firefox popup ads, every time I open my browser? I will NEVER ACCEPT ANY OFFER via this method!

Also, how do I change the defaulted "keep me logged in" check box to NO CHECK CHECK MARK in that field as default. This is a security issue!

Thank you

So, I was just going to Youtube, and on the search bar, there was a little robot. I hovered my cursor over and it said I was under remote control. The reason is DevTools whatever that is. I do some research and turn it off. Go back in and it reappears again. Please help.
