I-Firefox Community Forum

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

I am a web dev and have a user download link to an excel xlsx file. On my own system it downloads fine in Chrome but in firefox ot displays the raw contents. Is this a FF setting?

Searches in Oregon always default to Seattle, even if I put an Oregon city in the search bar

Cannot locate any Oregon businesses or restaurants in oregon

Firefox does not retain email login addresses for Fastmail email webpage.

I have used Firefox and Fastmail for many years and this has never been a problem. When I opened Fastmail previously and placed my curser on the email address box I was always presented with a choice of three or four email addresses. However now I am only presented with the first email address I entered since the Fastmail/Firefox upgrades.

I have contacted Fastmail about this and they suggested it might be a Firefox issue

i have made a major mistake trying to manage my bookmarks i need to delete all bookmarks and restore previous settings but every time i try to delete files or restore previous book marks firefox freezes. i have manged to copy bookmarks menu into other bookmarks and then copy other book marks back into bookmarks menu multiple times. have probably set a record for most book marks as i had over 1.3 million. i have managed to delete a lot of folder but i cant do anything with the ones i left without freezing

Firefox will not run on my desktop as it says its already running. I have uninstalled Firefox & reinstalled it with a fresh copy from the web but the problem persists. I open Task Manager & see Mozilla Firefox appears to be running: "Mozilla Firefox (3)". I end task which stops Firefox opening further but the same thing happens again when I try to open Firefox.

My PC is running Windows 11 fully updated as at today.

Can anyone suggest a fix?

It used to be that Firefox had different containers. I kept separate ones for shopping, banking, Facebook, etc. Now I had to erase my MacBook Pro IOS, and after a few days of trying to use Safari, I installed Firefox. But I can no longer see the possibility of using containers. I found them particuarly helpful when I had more than one account for a certain platform - with containers, I didn't need to sign out and sign in to switch users. It also (supposedly) kept Facebook from tracking our interests. Has Firefox done away with containers? Or have I simply forgotten what they are called (buckets, maybe?). I searched and searched the help articles to no avail. If they have done away with them, why?

By the way, Chrome (which I had to use at work) started offering a similar product and it was also very helpful.

I can't remove the fake "your computer is locked up" message, despite following advice on your and other sites. I even trashed Firefox, downloaded a new one, but on opening it, scam message reappears. I haven't found any solutions in the on-line forums I looked at.

Hi, i have formatted my macbook pro, before i have made a back up with timemachine. I'd like to restore my bookmarks but i can't find it on the back up. I have tried to find on Library>Application support but in this folder there is not the Firefox folder in wich i expected to find the Profile folder.

Please help me.

I made no changes to Firefox. It just stopped working. If I click on the icon I get a momentary hour glass, the hour glass goes away, and Firefox never comes up.

If I try to open it as administrator, it comes up but will not accept any web addresses. I can type in a web address but is doesn't go to the site. The screen just stares at me and does nothing.

Both Edge and Chrome work just fine. I have used Firefox for many years. I love it but has just stopped working. I have reinstalled it several times and the same problem occurs.

Using windows 11 on a desktop PC. Firefox has been my default browser for decades...issues have been very rare. But this is a catastrophic problem. One of those folders contains links to equipment mfrs, the other one has links to dealers and retailers. In the last month TWO folders and all their contents have vanished from my bookmarks sidebar and cannot be found anywhere on my computer. I NEED those folders...Where did they go and how do I recover them ?????

Help to do that will be appreciated!

I am not a "techie" kind of person, so please bear with me. I received the email from Mozilla telling me to update my Firefox.

Will Firefox 78.15.0 continue to work on my Mac after March 31, 2024? I do not use Sync. I do have many bookmarks and saved passwords. The email from Mozilla is a bit unclear what will happen. I am using an older computer running Mac OS 10.10.5 and cannot update to a newer system, so I cannot update Firefox. Thanks very much.

Dear Team Kindly help me for retrieve my details bookmarks and passwords very important to me.

i am reinstall my laptop and again install Firefox then login sync but no not sync old details retrieve please help us to me.

Hello, i have run Firefox for years on 2 separate computers each with their own data and now I want to sync them. My problem is I don't understand to the 2 different sets of data if I sync. Do the 2 sets 'blend' somehow? Does one set take primacy over the other (if so, how do I control which one it is?) or do I lose everything from both computers and start again? I've been wanting to sync for 12 months but I am so scared of losing information that I keep avoiding doing anything. Thanks Chris

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem.
