Diễn đàn hỗ trợ Firefox

On my Firefox homepage I had four rows of bookmark shortcuts. I recently decided to switch some of them out but I made a mistake and chose Dismiss. Now my homepage only has three rows of shortcuts even though in the options it still says four and there doesn't seem to be a way to re-add them or bring them back. How do I restore the slots that were dismissed?

I suppose this is a kind of support question, of sorts, but in my opinion this also has to be treated as a complaint, in a sense.

About one and a half months ago, Firefox became unresponsive, that is, it became awfully slow. I experienced just about every issue with the browser that was mentioned in the following support pages and support issues (posted by others) and I read all of those :

Secure connection and security warning error pages in Firefox https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

An oddball situation had occurred in which I couldn't for the likes of me go to my librarything.com homepage at each restart of the previous Firefox session, which also causes lagging when the session wants to connect to the other (normally unproblematic) website session tabs, and I also get multiple connection errors + insecure connection notifications for some of these websites. (sometimes refreshing a page does not help, sometimes it does)

I got bored reading all those support pages and trying out the solutions, because nothing seemed to help. In the long run, I decided to de-install the whole browser after backing up bookmarks, speeddial settings, passwords and the whole profile. Simultaneously, I also tested the connectivity to these websites in another browser (Brave) and this did not present me with any problem.

So I did the following :

1) deleted the whole cache and closed the browser 2) uninstalled FF with Revo Uninstaller (which has an option to remove all remnant files / folders/ registry items on the Hard Drive) 3) made sure to remove all cached leftovers from HD by using multiple cleanup tools in succession : 1) Wise Disk Cleaner followed by 2) Bleachbit followed by 3) CCleaner

Went to the mozilla website, downloaded and installed the last version of FF. Next, imported bookmarks, speeddial settings and passwords. Next, reinstalled the Firefox extensions I used before (without any lag until one and a half months ago). I also did NOT copy the stored profile but decided on starting afresh with a new profile.

Everything worked lightning fast and efficiently until a few days ago, when I received an automatic update of Firefox - 151.0.3 - and all of a sudden, the same problems are reoccurring. And again, I can't connect to an unproblematic website like librarything.com, whereas before the update I was able to without any problem !!!

What the hell is going on with these auto-updates ???

Win 10

As of today, this was the situation (image 1). I had to do a manual update.

Also, when I first visited here today, I was not logged in. I 'd like to stay logged in. Then, I couldn't have been here for more than 15 seconds, and this appeared. How can a session be expired when there was no session? Is this part of the reason I don't stay logged in?

Здравствуйте, на одном из компьютеров которыми я пользуюсь браузер выдаёт всплывающее окно со следующим текстом " this profile was last used with anewer version of this application. Please create a new profile." скрин прилагаю. на всех компьютерах win10, с чем это может быть связано?

Coming from Chrome for a very long time to firefox I am used to clicking an embedded audio opening a new tab with a "playthrough" feature. When I have tried this with Firefox it automatically downloads or skips this preview capability.

I recently installed firefox on my Windows 10 laptop, but i cant pin it to the taskbar via right click (this bug wont go away no matter what i do) and also cant open the start menu (also wont go away). I also tried to pin it directly via the exe, but for some reason, it opens another version of firefox, almost as if it was in another acount was logged in (i only have 1 account in firefox).

I had to reload firefox after getting xpcom error messages, now i can't work out how to restore my passwords,bookmarks etc from my sync profile that i set up months before.

I have been using this wonderful browser since 2012, and it has been my default browser ever since. Recently, I've been facing an issue where I can't upload images, audio files, videos, or any other attachments on WhatsApp Web through this browser. To verify the problem, I tested WhatsApp on a different browser, and everything worked perfectly there.

I would appreciate your advice on how to resolve this issue. Please guide me on what steps I can take to fix the browser and restore normal functionality.

Today I updated to FireFox 151.0.3 and now I can no longer drag my tabs. I drag tabs all the time. I drag them to rearrange the order. I drag them to put a bookmark in the folder I want in the position in the list that I want. I sometimes drag tabs to make tab groups. None of that is working now.

I do enjoy the suggested stories on my home tab from time to time. However, certain providers, such as the New York Times, are paywalled. I would like to be able to block stories from a particular provider such that I don't have to see a cool headline, click, and be disappointed by a paywall blocking the story. Alternatively, make it so that Firefox does not suggest stories that require logging into an account from the provider to read them.

After realizing what was being done to my PC, I unplugged it to stop the hacker. And I have since been able to recover my program, except for my ad blocker. Before this unusual encounter, I was using a free ad blocker. I want to restore it to its original status, if possible. Thank you for any help, Leman H Wilson at 7:09 PM 6-3-26

I was able to use Firefox web browser earlier today, but after trying to log in to Facebook, which failed, my account was no longer accessible, I saw an indication that my account was not connected. Do I need to update my software for Firefox. I've been having difficulties logging in to Facebook.
