Diễn đàn hỗ trợ Firefox

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

All of a sudden I can no longer add bookmarks to my Firefox desktop. At this point I can not even access the "Bookmark current tab." Are there settings that control the Bookmarks section. Thank you

My account was tagged/blocked by Mozilla. The account at issue has 2 factor enabled. I have a landline but now it will only text to authenticate. I had a school e-mail account but they changed and upgraded and dropped all accounts except for new/continuing students without notice (basically everyone until registration). Bottom line my phone was disabled by one vendor and my recovery e-mail by another. To access the microsoft store to correct an issue it required a new passkey. I submitted one. Now mozilla has blocked my password and microsoft requires me to login to contact the store or support but of course my issue is logging in. Around and around I go. I cannot correct a charge, microsoft is free to use my credit, and I have no way to notify anyone that something is amiss with the charge ( paying for a service already purchased, ie. double charged. I also noted a comment about that request being from outside the continental US, but have no ability to contact anyone nor to check/access my account. WTF

cleaning up my computer, I accidentally deleted firefox. I had a list of favourite links, and I lost them. Is there any way of recovering my list of favourites?

thank you, Glen A Goodale, [email removed]@gmail.com

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.

Desktop Computer. Still on Windows 10.

Not sure of category. This began when I launched the computer today. I opened Firefox and got the message "The bookmarks and history system will not be functional because ....."

When I started to shut down the computer (first mentioned step here) I saw there's a Window update. I selected Update and Restart. That went okay, but still don't have my Firefox bookmarks.

So I clicked on Learn more. I found the Firefox > Profiles folder. There are two folders, one from today - qkuxm6ws.default-release - 15...... 0196 with 94 items, and 7ghfiw 15.default, from Jan 5, 2021, with 3 items. I assume I should use the one with today's date.

BUT .... from this point, the information on this website was full of information - NOT step-by-step information telling me what to do with which files in this folder.

Also, I have McAfee as well as Windows Defender. I opened Windows Defender Firewall. State is On. Notification state: Notify me when Windows Defender Firewall blocks a new app. I've gotten no such messages.

Under allowed apps and features:

 "Firefox ... private not checked; public checked.."  
 "Firefox (C:\Program Files\Mozilla Firefox" - private is checked, public not checked.  

Can't make changes.

Under Overview window: Not checked is "Inbound connections that do not match a rule are blocked."

• • • • In the "Monitoring\Firewall folder" - Firefox (with path) is listed twice. Both entries have Private, Allow, NO Override -
      • Differences - the first has UDP; the second has TCP. Nothing under "Group."

My last bookmarks backup was Jan 2025. 😕 😟

I don't know where else to look or what to do. Please help. Kami

It's very hard for me to find where to go after clicking on the three line symbol in right hand corner. But when I finally did locate in Settings the section on passwords and sign-in info I turned that off. I was happy until I again signed into Mozilla and Amazon and my email address (which I use for ID) continued to pop up. Why do these things have to be so hard to find and then to make work. Please help. Thank you.

There is supposed to be Windows 11 on this computer, but something is saying Windows 10 didn't support something the end of Oct. I was on the site I'm trying to reach yesterday and there was no problem.

For the very first time, today I got the following, "Gah. Your tab just crashed." and it now happens every time. What's up? Is this a Mozilla problem? Should I be moving on to a new browser? Help!

Hi! I want to download the "Photoshow" add on. I can't because it says "Download the new Firefox and get the extension". When I check for updates it for Firefox it says I'm all updated. When I click the "download new firefox" I get the message "Your download was interrupted. But all is not lost." I really want this add-on. Is there another way to get it or to solve my problem? Thanks!
