Diễn đàn hỗ trợ Firefox

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

I did use yahoo email for long time but now I want to switch to g mail address for my own protection and will keep my home address and will use my personal information as is not further changes.

So I have had a favorite URL in Firefox for a decade or more https://www.outlook.com/owa to access outlook.com via web browser. Microsoft in Firefox only since the last upgrade does some weird looking and throws an error saying to try again later. If I delete my cookies for live.com and refresh the link it brings me to the sign in page where I can put in the email/password and it opens fine. If I close the window same thing happens and have to clear cookies, etc. Doesn't have the issue on Chrome or Edge, but thought I would make someone aware something odd is happening there. For now I just am using an alternate link https://outlook.live.com/mail/0/ and it comes up fine but it is not re authenticating again at that point.

Is there something I can do to avoid the error?

Now that my browser is Firefox I cannot get to my email or anything else on my computer. What must I do??? At one point I was signing in to Mozilla Firefox and it said that account already exists. This is very frustrating for an older geriatric. Please send me instructions to get back where I was. My present email address is [edited from public] @gmail.com.

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

Since a recent version of Firefox was installed the picture in picture control does not work. I have unchecked the option but It still shows in YouTube etc.

I know this can be disabled in about:config but I prefer not going there. I wonder if this will be corrected sometime, otherwise the setting option is pointless.

Another item: I have unchecked the search suggestions in settings but it makes no difference.

Input welcome.

Здравствуйте. Сайты с сервисами от компании Яндекс не работают - не грузятся. Пробовал почистить куки, перезагрузиться, не помогает. Открыл в новом приватном окне, все заработало. В чём может быть дело? Работать в приватном окне - не удобно.

I really appreciate this amazing new 'unloading' feature. It's just the function I need. However, I can't unload all the tabs I've selected. Only some of them are inactivated, and this problem occurs almost every time I choose a group of tabs.

After the most recent update on the 17/09 my search bar is permanently stuck blue (screenshot attached). Any idea how to revert this back to the grey it was before.

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

I know the system backs up bookmarks every day or so. I want to migrate all to a new PC. With a new Laptop it seems to have done so automatically, maybe through synchronize feature, I am not sure how I did that . I normally export bookmarks to a external flash drive as HTML. Just did also to a .json file type cannot find how to do that. Which format and method will be best? Have all of the old PC backed up through Acronis full back up. Will that have the full Firefox program with the bookmarks?

I have unchecked search suggestions in settings but these still appear when I search in Firefox with Google (for which I have disabled trending searches).

What is the point of the setting if it doesn't work?

hi, I recently purchased a new wireless mouse and keyboard... and my only problem is that there are a couple extra buttons on my new mouse... roughly thumb position... and are by default set to navigate backward and forward.... I'm running ubuntu linux... which results in accidentally clicking back midway through a video or podcast and losing my position more often than you'd expect... any idea how I might either reassign or disable them entirely on the software side of things? thanks. -dan
