I noticed that someone else had this question, but instead of answering it, it just got archived.

When browsing Youtube, the browser Back Button doesn't work. For example, if I start on the Youtube main page, then click on a video, it will show the video. But then, when I click the browser's "Back" navigation buttion, it does not take me back to the main page. The URL in the address bar will be the main page, but it will continue to display the video I just watched instead.

This only seems to happen on Youtube. It's been a problem for a while - possibly as much as 2 years or even more. And it doesn't happen every single time. However, it has been happening a lot more frequently lately.

It's almost as if Firefox just doesn't want to refresh.

I've tried clearing the cache. The problem persists. I've dried disabling all add-ons. It still happens. I've tried running it in troubleshooting mode. Still a problem.

I've tried to duplicate this in Microsoft Edge; it doesn't seem to happen there.

Firefox suddenly quit opening or running on one of my computers. I have tried to reinstall firefox to now avail. I now get a message saying it can't load profile. I would like to do a complete clean reinstall but cannot fine a way to do that.

I am using Firefox 122.0.1, Windows 11 with all latest updates. Recently my HP Laptop has been slow to respond. I rebooted and opened task manager. I started Firefox and it was using about 1500 MB of memory. I closed some tabs to try to recover some memory. However, Firefox kept taking more, more and more. After 15 minutes, it was at 10,000 MB and climbing, and my system was using 99% of memory. I don't believe Firefox did this in the past and this is clearly not working properly. Any ideas?

I AM UNABLE TO LOG ON TO USAA.COM. THE ERROR MESSAGE SAYS "WE ARE UNABLE TO COMPLY WITH YOU RE REQUEST." THE WEB SITE CUSTOMER SERVICE SAYS MY PASSWORD IS CORRECT AND THE SITE IS WORKING. PER THEIR ADVISE ALL HISTORY HAS BEEN DELETED AND THE COMPUTER HAS BEEN RESTARTED. THE SAME PROBLEM EXISTS ON ANOTHER DEVISE CONNECTED TO THE SAME WI-FI. PLEASE HELP. ACCESS TO OTHER SITES IS WORKING. THE SITE IS NOT BLOCKED AS FAR AS I CAN TELL.

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

Signon to GMAIL or Youtube Premium inside Firefox both return an error about using an unsecure browser. No issue with Chrome or Edge.

Hi there

I have found that certain websites aren't loading properly and that images aren't being displayed whilst the majority of pages are loading properly. Can someone help me with this please?

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,...

How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

Hi folks, So my university uses gmail and accesses with Duo Mobile. I usually use Firefox on a Win11 PC, no problem. This morning for some reason firefox will not let me even begin the login process. Chrome works fine. I have disabled four extensions (DuckDuckGoprivacy, Unpaywall, YoutubeNonstop, Boomerang) and restarted, no change.

Screenshot shows errormessage on Firefox, with functional Chrome screen in background.

This has to be a firefox issue? help please!

Hi there. I use mailjet for sending email newsletters and campaigns. The images that i was uploading into the mailjet templates where displaying fine both on mailjet and when sent to mozilla firefox users.

The problem is that for 10 days now; when i upload images in mailjet and sending newsletters; the images are not displaying in mozilla. In contrast, when i use chrome everything displays fine, both mailjet and email accounts.

I had a long chat history with mailjet support and they requested to follow these instructions to fix this issue first: https://documentation.mailjet.com/hc/en-us/articles/360058211453-Why-are-my-images-not-displayed-missing-in-the-Email-Editor I did this but i had no success so they requested me to use chrome instead of mozilla. But that is not the solution of the problem because this must address all different browser users.

Can you please help me on this?

Thank you,

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

Often I open a new tab & it's bugged. (It displays fine but the "right click" menu doesn't work.)

The fix is right clicking the tab itself (at the very top) & then clicking "reload tab".

Is there a hotkey for this instead? I hoped ^{f5} would work (control f5) but it didn't seem to.

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

Hi, my bookmarks toolbar doesn’t show when I launch Firefox. They always use to. When I click on View>Toolbar>Bookmarks Toolbar>Always Show - the Bar shows. When I click on any bookmark the bar disappears. If (in new window) I click on View>Toolbar>Bookmarks Toolbar>Always Show - the bar appears, when I then open new tab it does not show on new tab and when I click back to previous tab bookmarks are gone.

I have restarted W10 PC, no change.

Hope you can help, many thanks, David

Hello, as of the last week, my Firefox wont open any Excel 365 scripts, pop-up windows are enabled, I have tried with my Firefox account in multiple different Windows 10 PCs - none worked, there is no problem in other browsers.

What could be the reason?

Thank you
