Diễn đàn hỗ trợ Firefox

I've been a user of Firefox since day one, now to me the browser is utter garbage, always fighting to do something that was so simple in the early days of Firefox. Wheres that bring the internet back simple browser gone ???

Every update breaks something its like you have a bunch of kids sitting in a play pen hoping the next release will be wow waw great brill but no its turned to garbage, utter garbage, did you sell out to another company or something ??

I was hoping to be saved from Chrome but you just cant beat an old dog forever.

RIP Firefox Im done with it !!!!!

I actually signed up for an account for this, thats how strongly i feel ive been let down.

Hello, Flightradar24 is not zooming or scrolling smoothly. In earlier FF versions this was not happening. Other browsers like Edge or Brave work fine. Perhaps you can take a look at it and fix it. Thank you.

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

Dear Mozilla Support,

My name is Sizhe Xiong. Today when I launched Firefox on my Windows computer, the browser suddenly required me to select or create a new profile before continuing. I had no option to skip this step, so I created a new one.

After that, Firefox asked me to log in or register a Mozilla account. I used the same Gmail address that I’ve always used for Firefox Sync, but it seems that a new account was automatically created, and all my previous data — including bookmarks, history, saved passwords, and extensions — disappeared.

When I checked my local Profiles folder under C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles, I found several new folders created around the same time, but none of them contain my old data (all places.sqlite files are around 5120 KB).

These bookmarks and passwords are very important to me. Could you please help check if it’s possible to recover my old Firefox data, or if my previous Sync data can still be linked to my Mozilla account (using the same Gmail address)?

Thank you very much for your help.

Best regards, Sizhe Xiong

I lost my Firefox on my pc. I thought i needed to download it again but when I downloaded it, it was a different version and none of my bookmarks were available. I don't know how to restore my old firefox. Help, please.

Issue Summary: My website (mass-doc.com) displays blank thumbnails in Firefox's New Tab "Recent Activity" section, while other websites (Claude.ai, Ahrefs, FamilySearch, Fox News, Xfinity) display their OG images correctly in the same section. Environment: Extensions Installed: uBlock Origin, FireShot (both tested disabled with no change)

Evidence That OG Images Are Correctly Configured:

Google Search Console "Insights" section correctly displays my OG images Social media preview tools show images correctly Images load directly when URL is accessed in browser Image specifications meet requirements: 1200×675 pixels, 132KB file size, JPEG format

Example OG Meta Tags (verified correct):

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I am incredibly frustrated by the continuing problem of all my Bookmarks disappearing with the usual "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." This issue has been going on since NOVEMBER!!! I usually manage to get my Bookmarks back by closing all txt files that I need to keep open, store them in a new folder on my laptop, and then restart my laptop. This time, it didn't work.

Can anyone steer me to a permanent solution to this problem?

Thanks, in advance, for any help offered.

Using Firefox as my browser, I have over the last few days been unable to maintain a connection with the internet.

You will please excuse me as I am a 70 year old with limited understanding of the interaction of the internet and its terminology.

A couple of things you may need to know to offer me advise I just received a refurbished Dell laptop with windows 11. I'm using firefox as the browser comcast xfinity is my ISP I subscribe to NordVPN and NordPass

I am having a problem maintaining a connection to firefox.

I can look on the taskbar and see that I am connected via Comcast and the NordVPN and yet I will have displays of "you are not connected to the internet" or similar wording. If I need to include that, at these times, I look at the task bar and I confirm that I am connected.

In addition to this Windows 11 laptop, I have two active android phones. My Gmail, last I checked on the laptop was displaying vividly inaccurate time stamps to incoming emails. My phones however show the emails with accurate timestamps. (A difference of 4 to 6 hours like EST New York to middle of the Pacific Ocean)

I do have photos of these events, screenshots of sorts... but they're on the phone. I'm currently using the firefox browser to offer this post/question, but I sit in anticipation of it acting erratically. Finally I have downloaded a different browser to use while the firefox issue is being trouble shot.

Rather than add more possibly irrelevant information, I'll send now and let the community ask me questions.

Hello. i noticed that my shortcuts are missing. i went to settings to check if it's enabled (check mark) and it is in fact enabled. tried to reset my computer and the shortcuts are still not there. on the main firefox page there is actually no shortcut icons on there...at all. all of the options in settings work with the exception (of course) the shortcuts. i would like to know why this is happening...thx

I'm trying to figure out how to get the recommended stories independent of Firefox Desktop.

So, by default, what domain or IP does Firefox send API requests to when it fetches the recommended stories on the new tab page?

I own three laptops and they are in my Firefox account and synced. I have several bookmarks for site I frequently visit. On two laptops, based on my settings, when I tap a bookmark it opens up in its own tab. This is how I want these to function. For some reason, my third laptop does not behave in this manner. The new bookmark opens up on the tab I am currently in. It gets bumped and the new bookmark opens. This is exactly how I do not want it to perform. What is going on? Also, when I set up settings doesn't it work for all my laptops since I am signed in?

Hi. I just switched to Windows Defender for antivirus. On Google Chrome I had to add an extension so Defender will work with Chrome to detect malicious websites.

On the eicar.org website the test virus is stopped on the Microsoft and Chrome browsers, but not with Firefox.

How do I set up Defender to work with Firefox?

Thanks
