I am using the new profile switching feature in the UI, from top of the hamburger menu. Firefox is my default browser on Windows.

Now, I want all links I activate from other Windows programs to open in a specific profile. I use the other profiles for auxilary tasks.

Is there any way to achieve this?

I am unable to load Newsmax - I get the message: "Secure Connection Failed

The connection to www.newsmax.com was interrupted while the page was loading.

   Please contact the website owners to inform them of this problem."

It loads fine in Safari - maybe I should use that as my default browser.

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.

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.

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).

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!

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.

For the last two days, I have not been able to clear caches. Because the privacy and security icon is missing. There’s a privacy notice there. When I click it, there’s no area for me to clear cachets.

Please advise

Hi there! The reminder function for termin (for example three days before) doesn't work anymore, but before it works allways. I couldn't find the reason therefore.

hi i was wondering if there is a way to remove this shadow cuz i have the adaptive tab bar extension and i think it will look way more better without this shadow enabled

Recently, whenever i have to quit firefox, my tabs have all disappeared upon opening. I have tried all the suggestions in the Mozilla help and nothing seems to work. This used to happen from time to time which was frustrating but now it happens every time I need to quit firefox. "Recently closed tabs" and "recently closed windows" are greyed out when I try to use that. and there is nothing in "restore previous history". Thank you for your help.

Recently updated firefox on my iPhone and the tab page has changed. I don't like the new layout, is there any way of changing back. Finding it confusing that the page title is now at the bottom of the thumbnail and not enclosed with it.

Since installing Windows 11, the right click "send to/mail recipient" hasn't worked with Thunderbird. I located the "send to folder", selected and opened "mail recipient", and selected Thunderbird. Now the "mail recipient" option has completely disappeared from the send to drop down menu. Can anyone help please?

Using Firefox on Mac (iOS 15.6.1) - restarted Firefox for updates and it's deleted ALL my bookmarks - what the hell? Everything gone from the toolbar, but I can still see them on my phone?

(This is the last straw of a string of bad experiences with Firefox - I think I'm switching to Chrome if there's no easy solution!)
