Diễn đàn hỗ trợ Firefox

My Bookmarks and History are completely gone. I tried the recommended procedure to restore them from a back-up, but the supposedly automatic back-up files are completely empty. I have no idea how this might have happened. I have tried disabling some of my anti-virus apps to no avail. The only thing I can think of is that I may inadvertantly erased them when I ran a CCleaner scan. I could really use some help here!

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

When I go to google.com/maps, I immediately see a map drawing of my location - then as the site *finishes* loading, the display area CLEARS, leaving the menu and various "hover" items from the site.

Just...no "roads". 🤣 Just a big vanilla background image.

Google maps works in another browser - the issue is just in Firefox.

Currently on Win 10, running under Parallels on a MacBook Pro. (Maps works great under the Mac OS as well!)

Thanks,

Why was it done? Is there a setting I can change so I can see them work as animated favicons? Will you change this on your next update? Otherwise, I am going to have to roll-back the version.

A pop-up screen often appears when I use Firefox. It says hat I have a virus and that I need to call a phone number to remove it. It claims to be Norton,but I doubt that it ts. I have attempted to remove this with Microsoft Defender, SuperAntiSpyware and Trend Housecall but none of them work. Can you help me?

Firefox was using GOBS of CPU, so I killed the master process and relaunched, but after launch I couldn't get any pages to finish loading. I then hoped to copy URLs from tabs and paste them into Floorp (which is working fine, as is Chrome), but I couldn't even snag the URLs (dominated by YouTube pages). I ran a full-system virus scan, finding nothing. The most recent Windows-11 update on 2026-Jan-15 isn't recent enough to be a likely causal factor. Firefox has about twice as many extensions as Floorp, but it was running fine until late yesterday (it's now after 3AM). I couldn't get the extensions page to load, so I've attached a screenshot of C:\Users\Mike2\AppData\Roaming\Mozilla\Firefox\Profiles\oa7ou5xk.default-release-1715337056307\extensions There are several other profiles, but there's very little in them (one profile with a times.json & several profiles containing a parent.lock file)

If I reinstall, will I lose all of my tabs?

When I try to full screen any streaming site on Firefox I can see the desktop on the edges, the video isn't fully centered on the screen. I have tried updating Firefox, my drivers, restarting my computer and even checking to make sure the resolution and aspect ration were good. Is there maybe an issue or bug I can try and resetting with a setting on the browser?

I do not like the current Firefox. I am 'trying' to get my firefox the way it was in the previous session yesterday.

Monday 19th.

For some reason I click a tab this evening and I lost everything. Now it is a lavender color (ugg) and all my information, tabs, everything is gone.

Please help.

how to add Yahoo search as default search engine if Yahoo is missing on Firefox Search. on Search setting i can see different engines Google, Bing, Ebay, etc. but there is no Yahoo.

Hi.

I had to install a new OS disk. So, I created an account, and made a synchronization. Then, I made a security backup. When I installed the SO and Firefox, I logged in to sync. As soon as I logged, it automatically started to sync the random tiles it had after install. So, I had to use the places.sqlite and favicon.sqlite files. It got me half the tiles, and even those were misplaced. So, I had to go for the security html, and I finally got everything I wanted. But, now it says the account is not associated. If I login to associate it, when I shut down the PC, it returns to those half tiles, and out of order.

How can I get this right?

Hey folks!

Thanks for taking the time to look at this, simply put I am using the 'workspaces' app in windows power toys which allows me to open windows in specific configurations to make a workspace. The app allows me to open other apps with CLI args, so I can open Firefox to a preset url, or even predefined set of tabs.

This has got me wanting to use my firefox tab groups as a way of opening "dynamic" windows in my workspace. All that would be needed is a way to open a specific tab group from CLI, or more specifically a CLI arg that I can input into power toys workspace.

Please let me know if there is a way to do this. I checked the Firefox CLI [https://wiki.mozilla.org/Firefox/CommandLineOptions|documentation] and didn't find anything though.

If I delete my history of the websites I go on or delete my emails in which I use Yahoo and Gmail is there a way to save them in case I need some information from them in the future? Another words, they may be deleted in my history and I delete my emails in which i delete them also from my trash folder can I store them someone else that will let me see them in the future? Thanks

Three days ago this started happening. When I mouse over the Firefox icon on my task bar, I get a long vertical list of open tabs, the majority of which are blank. When you try to click the X (that appears on the right side of the list when you mouse over a blank space) nothing happens. In the past few days it showed a random mix of blank tabs and open tabs. Yesterday it only showed the open tabs at the top with a long list of blanks below. And today it's only showing the one tab I have active (despite having up to five tabs open before I took the picture).

Before this all started happening, it used to show large tab previews (not just text) that run horizontally along the bottom of my screen when I hover my mouse over the Firefox icon on the taskbar. Now it's just a list that goes vertically with all these blank tabs.

How to return things to normal? (tab previews horizontally without blanks)

I'm running Windows 11 Home, Version 25H2, OS build 26200.7623 and Firefox: 147.0.1 (64-bit)

Thank you, John
