When I open Vivaldi browser, the link in the address bar is highlighted right away. That's not the case in Firefox. Here I to either need triple click or use "CTRL A" The same is true when I open a new tab.

Is there a way to do that in Firefox?

Thanks a lot /Per

Starting today I am finding it extremely hard to login to some websites. All Firefox does is just sit with a spinning circle after entering a user name and it locks up the browser to a point the I have to go to the Task Manager to stop the FireFox process. I have restarted my computer and refreshed FireFox. I have scanned my computer for malware using Norton 360, Malwarebytes, MSERT, and Windows Defender and all negative. I am having no trouble signing in to a site like https://my.account.sony.com using Edge but using FireFox now is impossible. This needs to be fixed.

I got a new device and had to sign in and sync everything. When firefox asked about syncing I didn't realize it was asking about using the edge bookmarks to sync with. I tried to cancel but it was too late. Can I undo/remove firefox syncing to edge? Does this mean any changes in Edge will automatically change firefox now? I do not want edge bookmarks/settings. I want to get my old firefox settings back. If it matters: Windows 10 home on one device, Windows 11 on another. All browsers up-to-date.

Feature "Reopen previous tabs" are under check, but after closing browser by "X" and reopening it, it'll start load Home page alone. This thing works correctly only by "Exit" button in pop-up menu.

This isn't happened on previous versions before and I want you to make it reopen those tabs again, because I don't feel comfortable closing the browser any other way than "X" window button.

I understand that the "Bookmarks Menu" Icon (see attached pic) can be used and then: 2) "Manage Bookmarks" can be selected (to get to the "Manage Bookmarks" <selection> screen).

But is there a 1-click Icon solution to access "Manage Bookmarks" (other than the keyboard one)? Or is there a link address that would access the "Manage Bookmarks" screen directly?

When I try to watch video on YouTube or other places. I encounter green line and reverse picture. I have reinstall Firefox but it still persist. Can someone please help me understand how to fix it. As the video bug only happens in firefox. And not in other browsers such as brave or edge. i also se that other people have the samme issue exampel https://support.mozilla.org/en-US/questions/1429053.

I use MS Outlook for email in the Firefox browser. Regularly when I open a long email from organisations I subscribe to the email opens near it's end, it does does not open scrolled to the start of the email. This happens randomly with various websites, it is not associated with any specific website. I reported this to Microsoft Support. At their suggestion I tried using MS Outlook in Google Chrome. I have not experienced this problem in Google Chrome. For the last 3-4 days I have used Outlook in both Firefox and Google Chrome. On each day I have experienced emails opening near their end when first viewed in Firefox but not in Chrome. I have not had even one experience of this problem in Chrome so my conclusion is the problem must be an issue with Firefox's interaction with MS Outlook. I want to use Firefox but this problem is becoming very annoying and at the moment my go-to browser for email is Chrome. I spend several hours a day on-line and normally use Firefox for my internet browsing. I have not had any problems with any website other than this scrolling problem with Outlook. I'm not sure exactly when this problem started but have been aware of it for probably 2-3 weeks. This is a random problem, I don't have any screenshots to share with you. Thanks for your help.

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

I reinstalled Firefox, now 119.0.1 64bit on our Mac M2 now OS13.6 via download-reinstall in the owner account on our shared Mac. The "Firefox is being updated by another instance" line in About Firefox still has not gone away after closing and restarting Firefox.

Presuming this will disrupt future updates, I seek help.

Background: Last spring, I upgraded from a 2016 Mac on OS10.15 (which still appears on my Mozilla account) to this M2 OS12 now 13.6. I had previously set Firefox to prompt me for updates because they could disrupt my work on the old Mac. It worked fine up to 118 point something. Up to my ears recently in urgent other stuff, I deferred the prompt for 119. Then, frazzled, I just closed several 119 prompts. Today, after helping my wife use her account on the M2, I found in my Dock's active apps area an icon for something like Updater something-or-other. After a while, I swiped it away.

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

Hi... I did a Firefox refresh today. Prior to the refresh, my bookmarks were displayed of the left side of the browser page... now they are not. I can still see and access my bookmarks if I go into manage bookmarks. But, I can not figure out how to get them displayed as before. Would appreciate any help anyone can provide. Thank in advance.

Suddenly, now on FF 119.0.0.1, JPEG Images no longer open in new tab when clicked with mid-mouse-button (previous behaviour, wanted), instead they get downloaded, safed to DL-folder, and maybe opened in 3rd-party-app. I tried to change the Open-with settings, but to no avail - there's no option to 'Open in Firefox'/Internally. (Only Open with../Download)

I've tried older guides on the topic, which didn't apply here it seems, also cleaned cache, etc.

I have a work and personal profile. On my work profile, when I go to amazon, I see the pricetag icon in the URL bar and it works as expected. However, on my personal profile, it's not showing up at all; no icon, no prompt, it's like it doesn't exist for that profile. I've restarted both profiles, and it still isn't showing up.

I'd prefer to do my shopping on my personal profile, and not my work profile. Any ideas why it's not working on one?

When I visit an http site and specify a non-standard port, it automatically changes to https, which is not a site redirect but something Firefox changes. This site already has an https service, and the http service will redirect to https. I reproduced the same situation in chrome. Accessing the http service with a non-standard interface was normal. After accessing the https service once, the service with the non-standard port was also changed to https. Clearing the data will restore it. Is this cached? My HTTPS-Only Mode is turned off, and set an exception for this site. thx.

I often see that some pages take up too much memory. This critically affects the performance of my laptop with 8 GB of memory. However, I was unable to reproduce this behaviour. Now I have caught two web pages.

https://linuxhandbook.com/sort-top-command/ 

and https://www.tutorialspoint.com/how-to-find-number-of-ram-slots-in-linux The first page quickly takes up 1-2GB and continues to drain memory. The maximum usage was 7 GB on a laptop with 16 GB of memory. This behaviour is the same in Firefox and Chrome. The second page quickly takes up 2GB, which is very noticeable on 8GB laptops. Why do these pages take up so much memory? Most importantly, how can you protect yourself from such an unexpected memory consumption?

The Firefox icon on my taskbar has a great big green number 1 plonked on it. It doesn't seem to relate to the number of windows I have open or the processes running. It's there even when Firefox is closed. I thought it might be messages but I can't find those either. Its driving me nuts can you please tell me how to get rid of it? I'm running it in Ubuntu on a laptop.

Every time I try to login to my bank using Firefox New Private Window I get a message "Unable to login. Try again later." But if I then switch to Microsoft Edge browser using its private window I have no problem, no delay, in logging in. It has occurred to me that Edge is deliberately blocking or somehow delaying my login attempt with Firefox. Could this be?
