Trying to log into Nord VPN with my iphone but keep getting error that cookies are enabled. Turned off every tracking protection etc I could think of and still have this problem on my iphone.

Is there a specific place as nothing in the help for cookie managment.

The issue is very simple. When loading into the roblox website, the page becomes almost completely empty aside from the buttons at the top like Charts, Marketplace and the roblox icon at the top left. All of which do nothing when pressed.

The weird thing is that it works completely fine on an incognito tab..? Now I noticed something similar happening with other roblox's websites, where some parts of the site would break in very similar ways, but I thought nothing of it cause it didn't affect me too much. But after the new update, it extends to everything, not just one sub-page of roblox, the entire website is like this.

I removed my extensions and restarted my browser to see if that would fix anything but it didn't help.

When Pocket was replaced by TenTabs, my Pocket extension vanished and I'm unable to locate the new TenTabs one -- if it even exists. Is it possible to "bookmark" TenTabs articles? If not what was the point of the change other than to make the product useless?

I really do like the new vertical tabs and I have them set to be just icons until you hover the mouse over them and then they fly out and I can read the names of the tabs. My problem is that when I switch a tab or do anything that makes the tabs expand to see their full names if I take the cursor off they fly back in but if I put the cursor on any area of how far the tabs came out to in the next few seconds they come out again even though I haven't put my cursor over the tab icon. This is really annoying for forums and really for general browsing as if I switch to a tab and want to interact with anything where the tabs came out to I have to wait like 5-10 seconds before I can click anything on that part of the page or else the tabs come flying out again. Is there any way to make it so the second my cursor isn't over the tab fly out that they will go back to the compact mode and won't come back out unless I hover over the tab icon again to alleviate this problem? I find I will often switch to a tab and then move my cursor off to the page and the names collapse so there are only icons left but I try to interact with something on the left side of the page and the tabs fly out way before my cursor goes near the tab icon and I have to take my cursor to the right then try going back to interact with that element and most of the time I have to go back and forth a few times before the tabs stop flying out so I can interact with that portion of the left side of the web page. I really like the vertical tabs but I want to be able to edit the time it takes for them to not fly back out if your cursor goes to where they had flown out to immediately, so zero seconds, instead of the 3-10 seconds or whatever it is set at by default.

Thanks!

Environment - Device: Acer Neo 16 (PHN16-71), 2023 model - OS: Windows 11 23H2 (Build 22631.4974) - Browser: Firefox ESR 128.7.0esr (similar issue observed on 140esr) - Current version in use: Firefox ESR 143.0.4 (64-bit) - Graphics: Hybrid – Intel UMA + NVIDIA RTX 4060 - Drivers:

 - Intel UMA: 31.0.101.4146 (UMA-labeled)  
 - NVIDIA: 551.76 (GeForce Game Ready Driver)

Issue Description While using Firefox ESR (128.7.0esr and 140esr), the laptop’s built-in screen occasionally begins to flicker, and after prolonged usage—especially when browsing Facebook for tens of minutes—it gradually develops severe distortion, resembling water damage or ripple effects.

Key observations: - Screenshots appear completely normal, indicating the framebuffer is unaffected. - No external monitor has been tested yet; the issue is only observed on the built-in panel. - Rebooting temporarily resolves the issue, but it recurs unpredictably. - This issue never occurred on my older laptop (Acer V3-772G) using the same ESR versions.

Steps to Reproduce 1. Launch Firefox ESR (128.7.0esr or 140esr) 2. Browse Facebook continuously for tens of minutes 3. Screen begins to flicker, then gradually distorts 4. Take a screenshot → image is normal 5. Reboot → screen returns to normal

✅ Expected Behavior The screen should remain visually stable during browser usage, without flickering or distortion.

Actual Behavior The built-in screen flickers and eventually distorts, while screenshots remain unaffected. This suggests the issue may lie in the final stage of the display output pipeline, possibly involving the TCON (Timing Controller) reacting to GPU output or Firefox’s rendering behavior.

Additional Notes  

- Hardware acceleration was disabled in Firefox for testing — the issue still occurred (on older versions). - No similar behavior observed in Chrome or Edge. - BIOS screen appears normal, ruling out panel damage. - After upgrading to Firefox ESR 143.0.4 (64-bit), the distortion issue has not reappeared for two weeks, though minor flickering still occurs occasionally during browsing. - Interestingly, when distortion or flickering occurs while browsing Facebook, switching to another website immediately causes the screen to temporarily return to normal.

 This suggests the issue may be triggered by specific rendering patterns or GPU calls on certain web pages.

- This may indicate a rare interaction between Firefox ESR and specific hardware configurations (UMA → TCON → panel).

A few days ago (today is November 9th 2025), my PC restarted itself while idling and when I got back, all my bookmarks in Firefox were just gone. The bookmarks toolbar, which I use constantly, was also gone. Furthermore, I can't even create new bookmarks. And I mean of ANY sort. Doesn't matter if click the little bookmark star when I'm on the page I want to save, or if I manually try to type it in by right-clicking the toolbar and choosing "Add bookmark..." None of it works!

I tried going to "Manage Bookmarks -> Import and Backup -> Restore" where I see 12 restore points. I've tried them all, but I get the same message every time: "Unable to process the backup file"

I've searched the Mozilla support articles and have only found one other entry from a person who seems to have had the same problem, here: https://support.mozilla.org/gl/questions/1504803

This person managed to solve it themselves by using the "Refresh Firefox" option, so I tried that, but it didn't work. The only thing I got out of it was losing all my extensions. I had been warned about that beforehand, so while it's a little more than just annoying that I've lost my Avast! Password Manager, which had a LOT of passwords I can't remember, not backing that up manually before running the refresh was entirely a brain fart on my own part.

Just to be sure, I've checked my Windows Update history to see if the culprit could be Windows rather than Firefox, but the last one was the 25H2 update that ran on October 17th. If that had been to blame, the problem would have manifested itself much earlier, so I'm fairly certain that has nothing to do with it.

So, two problems to solve here:

1. 1 - How do I fix this bookmark problem?
2. 2 - Is it perhaps possible to restore my Avast! Password Manager?

I would be VERY grateful if someone could help me with this! Like the person in the linked post, collecting these bookmarks has taken me over a decade and they've been used so frequently that - at least for some of them - I don't even remember the URL's of the sites anymore, because I literally haven't typed them in manually for years.

When i open firefox, i can choose what profile to open. I have two screens, so i was wondering if it was possible to be able to open both profiles i use, and have one on each screen. If not possible, would it be considered for an update in the future? It would make it easier, so i can have my personal profile on one screen, and my work profile on the other.

I recently bought an new HP Win 11 PC to replace my current Win 10 machine. Running latest FF 144.0.2 on both. How do I transfer my complete FF profile (bookmarks, bookmark bar, login data, EVERYTHING) to the new PC? Want the new install to be an exact functional copy.

THANKS!

For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

So this morning I sat down at my computer which was already on and working fine yesterday. Today my bookmarks had disappeared. I rebooted several times, closed and reopened firefox several times and I don't remember what else I clicked on but my bookmarks had reappeared. I sat down at the computer a while ago and opened firefox and my bookmarks seemed to have disappeared again. Before when I clicked on bookmarks up on the toolbar my bookmarks would appear. Now I have to click on bookmarks then bookmarks toolbar to see them and now all of my logins are gone. Should I just ditch this browser and use chrome or is there some simple fix? I never have had as many problems with a browser as I've had with firefox and I no longer see an advantage in using it.

When I want to login with my Firefox account it asks me for a code as 2 factor but I can't remember that I ever signed up for 2 -factor . I have 2 apps fro 2 factor: google and Microsoft but neither has Mozilla identification in it. I would like to sign up for 2 factor but it looks like someone already did that for me. What now?

Whenever I play videos on YouTube in Firefox, the video is always choppy and does not run smoothly. I’ve tried restarting the browser and checking my internet connection, but the issue continues. This problem only happens in Firefox, not in other browsers.
