Firefox Support Forum

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 switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

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.

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

This started a week or two ago intermittantly on some websites. Today I cannot see any images of amazon items in the shopping cart. I can see the thumbnails in the right side bar, and if I click on an item, the image appears on its for sale page. Ebay usually shows the first image, but the rest won't load, unless I click on "unable to load images" and then they might. Or if I use the icon to put the images in their own box, I can < and > to navigate them

Turned the new "secure DNS" feature off & on, no difference. Turned off NoScript, no difference.

My laptop glitched while doing a Windows update and it chose to not load certain apps upon completing the update. Mozilla Firefox was one of the apps it chose to delete and I lost all my bookmarks with my login information to all my accounts, can I retrieve those?

I have saved a lot of shortcuts bookmark on my homepage,yesterday when i opened my firefox,it was all gone and it went back to default homepage. what do i do to recover it.

I have recently noticed that I can no longer see the "comments" sections on various "News" websites. I first noted this with Townhall Media sites (Townhall.com, Redstate.com, Pjmedia.com) and now Foxnews.com. What has Firefox changed that has resulted in this issue? Most of these sites use Disqus for comments. I have tried explicitly allowing content from these sites. I've been using Mozzila products since the advent of Netscape. Always found Firefox to be superior to other browsers, and I'd like a little help in finding out what is causing this problem. Thanks.

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

Can not find how to do FireFox on the new setup. HATE the new Fire Fox emailing format!!! One thing is the ongoing back and forth with others I sent an email. Usually to reply, just had to click on reply and send my response fro the just sent email. I HATE THE NEW SET UP!!!!

I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

Regards,

I first mentioned this in r/Firefox, and was asked to re-post here.

My FF just updated to 127.0.1 even though I have "Check for updates but let you choose to install them" and told it to wait. This was on a Windows 11 box. Everything seemed fine, but then one of my tabs crashed. I selected the reload tab option, at which point it informed me it could not load the tab because a background update had happened and I was now required to restart Firefox.

I'm not certain what version of FF I was on, I believe it was either 126 or 126.0.1.

Now, to be completely fair, I cannot with 100% certainty say that I clicked on the update later option. That said, as I _did not want to update then_, and I have put off the update before, it seems unlikely I would have made the mistake, but I wasn't recording everything I did so I can't play it back and prove it. My initial reaction was to associate it with the tab crashing somehow, as everything was working as expected right up until that moment.

Thanks
