Firefox freezes some seconds or some minute after I open the program, I end task and wait to reopen the program, opening up the program it continues to freeze. I've reset firefox multiple times, cleared cache & webdata, completly uninstalled FF and reinstalled it, doesn't solve it. Starting firefox in troubleshooting mode also freezes and hangs. After end tasking firefox multiple times it eventually stops freezing but during the next day when I open the browser the issue returns, The same goes after I reinstalled it after uninstalling it, works for the rest of the day but the next day the issue returns. Background: I switched from chrome to Firefox some months ago and imported webdata from chrome to FF.

I am using FF 158 on Win11

I noticed that apps after login are being restored with my previous session even if i close the browser and restart the browser!

ways to reproduce the problem: - Login to an app - Exit the browser, ensure the Firefox.exe is not running using Task Manager - Restart the browser and go to the same app URL. - At this point I expect the app to prompt for a password again (It does prompt for a login on Chrome and other browsers including FF 154) however on FF 158 the session is still active!

I have checked the settings in FF 158 and disabled the restore Tabs option on startup however the bug still exists.

This is a serious security issue. Kindly investigate and address

Regards Sanjay

Hello. I am back again with the same issue that I presented on the forum post three months ago. https://support.mozilla.org/en-US/questions/1594903?utm_campaign=questions-reply The difference is now it is happening on Firefox v157.0.1;everything else is identical. Qubes os R4.3.2 with Firefox 157.0.1 in a Fedora 44 xfce VM. To recap I open one window for Proxmox Datacenter Manager and as soon as I click to sign in Firefox completely disappears. I can open this in Chromium browser and Firefox ESR v.140.17.0 esr perfectly fine. Please consult the original post for all I did to troubleshoot this. I am working with the esr version now but would like to help put this issue to bed. Community members stepped up last time to help me so I am here to do my small part for others. Ask for any info you need and I'll reply ASAP. Thanks in advance. SDS

Hello,

I use Firefox on Windows 11 and it is up to date. I use Youtube and for the last week or so it has been a little weird. You cannot click on links for videos to load. Youtube will tell me that I am off line even though the PC is connected to the internet.

The comments underneath are not displayed at all. I only see grey bars and the circle for loading.

If you click on the 3 bars on the top left I only get a message about copy rights....

I did delete all the cookies, history, refreshed.

Youtube does display o.k. in edge.

Is this a problem with Firefox or youtube?

Every time I try to access a website using my bookmarks, they don't work, i.e., nothing happens. I have tried numerous bookmarks to be sure that it is not one or two where the web address has changed. I am considering uninstalling and reinstalling Firefox to see if that will over come the issue.

From my point of view Firefox is normally excellent and definitely my browser of choice. So this problem has come as a bit of a surprise.

Firefox has exceeded all previous mess-ups by upgrading itself today (apparently sometime when my battery went flat and was then left recharging), and this happened despite my account being set for 'upgrades to be only installed manually'. Now every bookmark, all passwords and all the settings of my Home Page have been erased. I have no 'restore point' to resort to as supposedly all this info is synced to the cloud. But I can find no method to retrieve any of these files let alone one to restore them. This is a nightmare. Please help.

Firefox updated without my knowledge, and all my data, including passwords and bookmarks, disappeared. My profiles still exist, but everything else is gone. I couldn't recover my data manually or through about:profiles. When I first opened Firefox and saw that everything was missing, I was prompted to import from Chrome and did so, so now I'm wondering if that messed things up. I just want my passwords back!!

As much as I hate ads on YouTube I don't want Firefox to block the ads because if they find out you are blocking ads they will block you from Google and YouTube. I have Google pages and other things on their sites that have been there for years. Plus, I feel like I'm stealing a service by not lets the ads run that pays their bills and the content creators on YouTube. Please tell me where in Firefox I can turn the ads back on.

I have used Mozilla products since Netscape Navigator came out in 1995 I think it was. I went to a local internet provider and brought home a 3.5in Diskette and it loaded Netscape Navigator with my info all filled in for email, Usenet, Webpage publishing and a few Bookmarks to get started. I still use SeaMonkey for my email because it still has email addresses from the 1990's. I have Thunderbird for email on my phone. Anyway, thank you for all your work over the years.

It bypasses my DNS when I turn it on and I don't want that to happen. I want this PC to never be able to turn it on again. That probably isn't possible, but I gotta ask. In the meantime: how do I use LinuxMint's firewall to ban the usage of the VPN?

Also: can the firefox devs make that an option? To have the option to never turn it on again?

About 4-6 weeks ago Chase started throwing an error message when I tried to log in. Some other banks, credit agencies, brokerage houses also same thing. The work with Chrome and Edge.

Can Mozilla get past this or do I give up and use a predatory browser?
