Firefox Support Forum

Something went wrong w/ the mouse, some of my tags disappeared & wasn't able to recover them via Ctrl+Z, so I decided to perform my 1st [Restore] (never had to do 1 before), since I had just recently done an [Export Bookmarks] & a [Backup]. Everything seems to have gone Ok, except that for every tag, all of the bookmarks listed under the [Name] column are duplicated. When I right-click & [Show In Folder], they both show in the same folder. When going onto their folder, they are only shown once, so there are no duplicates there. When I attempt to [Delete] 1 of the 2 duplicate entries they both get [Deleted], so I can only conclude that they are 1 in the same. But the question remains, "How can I fix this duplicate condition?"

Another related & interesting behavior is that, from any bookmark folder where you can clearly see there are no duplicated bookmarks, when you do a [Search] from the top-right-hand search-box, the "results" are also "duplicated", although you might need to sort them by clicking on the [Name] column control. So, I can go to any bookmark folder & clearly see that there are no duplicate bookmarks, but when you do a [Search], that's when you get duplicate entries. That leads me to believe that this is the result of the [Search] function, & thus for some odd reason the [Search] is generating "duplicate entries". And then perhaps, both the [Tag]s & the [Search] function are related.

Also, this "duplication" does not happen on newer added bookmarks, after the [Restore] was executed, & it's only a phenomenon that affects those bookmarks that were saved by the Bookmarks' Library [Backup] function, & thus this anomaly was introduced by the [Backup].

Actually, I just realized the problem is more complicated than I thought. The reason any search results in "duplicate bookmarks" is because there are 2 sets of folders, 1 set above the other, & if you don't scroll down all the way you won't see it. So that's why there are actually "2 Sets Of Bookmarks", because there are "2 Sets Of Folders", 1 above the other. The problem is that when you delete any "Duplicate Bookmark" you delete them both, & not just 1 of the 2 bookmarks.

I wonder if it would work, to "Delete All Bookmarks" & then do a [Restore]?

Could "Mozilla Support" answer that?

Don't know why every time I attempt to [Post A Reply] & get an "Error",... So I'm going to post my reply right here,...

Fix: (2024-02-19) Of course, I did some testing before I concluded what was the best approach, but since I noticed all of the "Bookmarks Folders" were duplicated under [Bookmarks Menu], an easy fix is to go to the "bottom duplicated folder", right on top of the [Other Bookmarks] folder, & "Select It" (by clicking on it) & [Delete] it (w/ the [Delete] key on your keyboard). Do this 1 by 1, until you reach the "bottom folder" of the bookmarks' folder you certainly don't want to delete. Close Firefox & then reopen it - to make sure Firefox takes care of any garbage-collection. Then do your Bookmarks' Library [Export Bookmarks To HTML] followed by a [Backup], & you are good to go.

Actually, I don't know what introduced the error. Don't know if it was Firefox's [Restore] function, or it could have been me (by accident) w/ some "unnoticed & unexpected" move of the mouse/trackball, which accidentally duplicated all of the folders w/o me noticing, & that is why all of the "Bookmarks" were "duplicated".

Happy Firefox Browsing,...

Using FF 100. Last week the Washington Post suddenly will not display article content correctly. Main page is fine, but when I open a story, I get code and a page with many blank areas. Story content appears with small print.

No problem in Edge nor Chrome.

I currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

Starting about a week ago, when I use Firefox 124.01 on my Windows 10 PC to visit Ebay, the pages show in Portuguese, and the country shows as Brazil. I'm in the USA. This problem does not occur when I use Chrome, Opera or Edge. Any idea about why this has happened and what I can do to fix it. On Ebay, I can manually change the language and location, but if I close Firefox, the problem returns. I'm using the version of FF that keeps no cookies or history. Thanks

Starting on 12/1/23 Firefox browser on Windows PC is Not Responding while loading up bookmarks toolbar. Switching to "Never Show" is only way to load the browser. Trying to open or manage bookmarks freezes up the FF browser again.

I hope this applies here. I tried using the "-p" command fro Librewolf. Wiped out my sessions and settings.

Is there a way to do this in Firefox and or Librewolf?

TO MOZILLA DEVELOPERS

In spite of hundreds if not thousands of users reporting this issue over and over again, and your suggested workaround to reduce memory usage in the settings that doesn't do anything - FIREFOX is still using unacceptably HUGE amount of memory.

With just FOUR (4) tabs open in one window, in the Task Manager I can see 17 (!!!!!!) Firefox windows open using 830 MB of memory. The highest usage of all my apps including memory hungry media apps. It's using THREE times as much memory as my Adobe Audition processing edits of a 1.5 hr audio with several clips.

This is insane!! You have gone crazy with caching to the point of making this browser unusable.

It's freezing up and crashing my Audition so before I work in it I must shut Firefox down completely - and I work on a powerful tower PC designed for media.

If you don't seriously cut back on this insane caching for the sake of browsing speed IN THE NEXT UPDATE, I won't be using your browser at all, it's simple as that. I'm already migrating my bookmarks and setting up Chrome which uses about half the memory that Firefox does with the same tabs, and I suspect that many users will follow suit.

The workarounds you offer DO NOT WORK. Any app that uses more than 500 MB of memory at any give time on my computer - goes.

I have to create a new question because when I try to reply to the answers I received the system comes up with an error page.

My version of Firefox is 120.0.1 and has been downloaded from the Mozilla website.

The problems occurs with all PDF file both local and from the internet.

The attachments are highlighted in blue in t he opened PDF file but cannot be opened. There is no way to click on the attachments.

Attached is a screen shot of one PDF file because I cannot attached the PDF file itself

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

Although I had long ago selected "Open Previous Windows and Tabs" in Start-Up, my windows and tabs were not restored when I inadvertently quit Firefox this morning and restarted. I then went to the three horizontal bar Application Menu > History to look for "restore previous session", but that button was missing.

So I have two questions: 1. Why didn't my selected preference, "open Previous Windows and Tabs " at Start-Up work? Is there a fix? 2. What has happened to my "restore previous session button in the History tab of the Application Menu, upper right of toolbar? Has Firefox deleted the "restore previous session" button? Can I reinstall it in some way?

I'll be grateful for advice. Thank you
