Is there a way to reset the Most Visited list? It's not accurate, since it has X and twitter on the list. I stopped using that site over a year ago. If I can't edit the list, is there a way to just get rid of Most Visited?

Hello,

Today my Google start up page turned Black. All other sites are normal colors. I tried basically all that I could to keep the background to system settings, no themes and no extensions added except for Image extensions (that I have no issues with). I have Firefox Version 144.0 (64-bit) On a Mac Mini OS 10.15.7

Should I do a Firefox Reset? Please help me with this issue.

Thank you, Phil Khoury

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Being able to tell anyone what's going on is almost impossible. I am thinking of deleting Firefox despite having been using it for years, a loyal customer who subscribes to your VPN. When I log in my pinned tabs do not open the web sites, I'm told I've got connection issues, I've removed the sites from tracking protection, X tells me that is an issue since it only started after the update before todays update. What is the point of pinned tabs if they don't open? If I can't resolve this issue I will use Chrome, All of my pinned sites open there I just have to get used to using another browser, I don't like Chrome very much but I'm pulling my hair out getting no joy from Firefox. There has to be a better way of contacting Firefox than spend ages online as though it's top secret! I'm using windows 11 24H2

just recently firefox has been adding pop-up summaries to each address bar open tab .... the summary is a tiny 5 or 6 word pop-up describing what that website is supposed to be doing and the pop-up appears instantly whenever the cursor contacts that tab..........how can i turn that unwanted pop-up feature OFF

I had to replace my hard drive recently, and with it my Firefox install. I managed to transfer everything over to the new install, except for the URLs in Reading List. The extension itself made it over; just not any of the URLs I stored in it.

In theory, I know that I can scrounge through the Firefox install on my old hard drive and grab the necessary files, but I have no idea how I'd go about doing that. I can't rely on folder names, since those are based on extension IDs that are generated when I install the extension, and the files themselves are too opaque to glean anything useful from (Notepad++ didn't turn anything up, so I'm assuming the extension data's compressed).

Other than that, I've tried:

• Running this tool to see if there was anything I could use. There wasn't.
• Trying Load Temporary Add-ons to identify the Add-on I wanted. I accidentally erased my feeds on RSS Feed Reader doing this, so there's another extension whose data I need to restore. (It was fine before I tried Load Temporary Add-ons.)

For example, this code in userChrome.css will work for showing a custom favicon on the bookmarks toolbar:

.bookmark-item[label="Bookmark"] image {

   width:0!important;
   height:0!important;
   padding: 0 0 16px 16px !important;
   background:url(custom-icon.png)!important; 
   background-size: 16px !important;

}

However, after a recent update, if the bookmark is located inside a folder, the custom favicon will not be displayed and it will revert to the websites favicon.

See the attached image example of a bookmark on the toolbar vs. inside a folder.

ブラウザゲームサイトUnityroomなどでゲームを遊んでいると、Cookieの容量が10ギガバイトを超えることがよくあります。 どうやら10ギガバイト以上のcookieをFirefoxでは保存できないようです。 FirefoxでのCookieの容量を10ギガバイト以上にしたり、ページごとに個別に管理できるようにしてほしいです。

For the past few weeks, I have been intermittently but stubbornly getting the beachball of death when I open Firefox, coupled with Force Quit. Sometimes I force quit and then restart and it's fine. Sometimes I force quiet repeatedly and it continues not to open. Sometimes I restart my laptop and that fixes it, but sometimes not.

I do have a lot of tabs open, but i have always had a lot of tabs open. This thing is new.

What could have changed? What do I need to do, fix, trash, or curse?

(In simple language, like for your unsavvy grandma please?)

So my question is Firefox is on my Cent OS 10 machine and it only shows the close button on the upper right corner, I would like to know two things, 1. How to add the Minimize, Fullscreen buttons to just the close button on the upper right corner. 2. How to get my menu bar back - the home button and all of the other goodies that normally show on the left of the browser just above the Forward, back and refresh buttons?

Thanks in advance for the help.

So, whenever you open/close the application menu, it fades in/out respectively. It's super disgusting I don't even know why it's not disabled when I have animation effects turned off on Windows. like bruh

This actually happens on multiple UI thingies, I just realized. -_- So if there's a way to disable all these terrible things I'm open to it. (ignore the reply i made, i didn't realize i can edit my question 😹)

i used to be able to scroll down in full screen and with the new version i can't and i used to be able to see the queue list and now i can't !!

How can i get the older version cause this one i really don't like

I recently got a new computer running W11. As always, the first thing I did was download Firefox and set it to my default browser. Then I logged in and synced. Firefox picked up some things - like my passwords, but not a single instance of history, not a single bookmark, or the tiles of frequent websites seen on the new tab page. Thinking something had gone wrong, I uninstalled FF and then reinstalled it. No change. As I was researching what to do when FF syncing fails, I realized that FF is not saving any data in history. NONE. I fiddled around with this situation for about five hours and it showed NO history of websites/pages visited. I went to a few common websites by name, typing www.ebay.com into the search bar (for example) and since that was a website I had now "frequented" I expected it to show up as a tile in the new tab page, but it didn't, even after closing it and opening it several more times to demonstrate (to FF) its frequent-ness.

What could be causing all this? I assume some settings in about:config are off, but can't find any information searching the web. No matter how I state the question, I only get responses like what to do if FF doesn't sync, NOT what to do if FF doesn't collect any history. Honestly, this is a standalone private home computer. It doesn't actually HAVE to sync with work. But it's not very useful to have a browser that collects NO history.

Sorry this is so long, and may I say, any help will be seriously appreciated.

As of yesterday, Oct. 14, 2025, everything in my Firefox Bookmarks and History is gone. This is the message displayed: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I have tried to recover them by different suggested means, but it would appear there is NOTHING to recover. Everything in Bookmarks says EMPTY, and I can no longer save any new Bookmarks, it just not allowed. How and why did this happen, and what am I supposed to do? I had hundreds of things Bookmarked, many of them were important to how I run my business, and now are seemingly all gone. This is very upsetting and would appreciate Mozilla getting this straighten out. I need and explanation and resolution.
