Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

Per title. If I go to bookmarks->bookmark this tab OR clicking the star icon in the address field I always want it to pop up and ask me where to save it, without having to remember to double click the star icon, or go edit bookmarks menu to move it.

This seems like a poor design, at least for me when more than 90% of the time I don't want it to be in the last used folder. I have been adding bookmarks for decades and it has always asked me where to save them, so muscle memory forgets to go back and edit the bookmark I just saved, and then later on I have to go back and change them all because they are never in the right folder.

I understand if I double click the star in the url it will allow me to change it, but when I'm busy I don't remember to click it again, or double click it, then my bookmark is lost and I have to go searching for it and edit it and it's a hassle.

Is there an about:config setting I've missed to re-enable this basic feature to reduce all the clicking?

I've tried browser.bookmarks.editDialog.showForNewBookmarks both false and true without any change to the behavior.

When I click on a bookmark, FF opens it in the current tab, overwriting the site I had open. I have to add a tab, then click on the bookmark to have it in a new tab. This is an annoying extra step. How to I change it? I already tried the open links in new tabs instead of windows. Makes no difference On or Off

100% of my bookmarks have disappeared. I tried backing up to older version a month ago and still no bookmarks were found. I had over 2000 bookmarks. any suggestions?? Marty

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

I opened up Firefox just now to find that my two profiles currently in use are completely inaccessible. I was faced with a "Create Profile" dialogue that launched me into a brand new profile with none of my settings, keybinds, cookies, extensions, anything. Despite this, I know for a fact that my old profiles are *still* there. As you can see my profile folders are right there, with all their data intact as far as I can tell from inspecting their contents, yet they are not accessible from the about:profiles.

Please help me. What is happening with the profile manager? How do I access those old profiles?

After the latest Firefox update, I could run YouTube without problems for several weeks. Now YouTube will not run. How do I fix this issue? I suspect it is due to an adblocker but not sure!!

I am using the Raindrop (raindrop.io) bookmark manager. It has been working fine on Firefox for years. However, with my recent update to Firefox 140, it is broken. Specifically, I can no longer use the highlighting function. It works fine on Chrome, but not on Firefox. I've seen several similar reports on Reddit's Firefox forum (r/firefox).

What to do? I don't want to have to switch to Chrome. Suggestions appreciated.

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

There is one particular website that I use quite frequently. Lately I haven't been able to log onto it without encountering a page verifying I am a human, and I can't proceed (the page just loops). This has happened on other browsers too, though I fixed the problem there by disabling my adblocker. But that doesn't help here on Firefox. Any suggestions?

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

I cannot sign into my att/yahoo email while using Firefox. After calling AT&T they told me to use Microsoft Edge which I told them I would not! When trying to sign in I receive the error message "It's not you, It's us" try again. It is my belief that att is trying to coerce me to change browsers so they can spy on me

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!
