after the last Firefox update the zynga game Farmville 2 will not load. It gives me a screen to fix mentioning chrome..but all efforts to manually fix referencing Firefox have failed. Odd that I can load the plain Zyngagames.com on Edge but it seems they too only load a "local" game that is not connected to any network. Help also mentions to make sure I allow to redirect but that "Options" feature to do so is not there. In fact it seems like the Firefox menu system is even much different and expanded. I will add the screens I have tried etc. Pop ups are allowed, turned off enhanced etc. but cannot find any reference to "third party redirects" Any suggestions are appreciated.

Hello, I have noticed that using firefox without closing the browser for a while causes the memory to keep rising. It looks like it has a memory leak. After 3 days of watching YouTube I was using 4GB of memory. It was causing Slow Downs.

I have included 2 images with what is actually running and I have 2 Tabs in Standard Browser of Google and this Tab for this report then a YouTube dedicated browser using split tab.

On my personal computer, I have a Profile for work and I was logged in via a Mozilla account using my work email address

I've recently set up a similar thing on my work computer. Signed in using Mozilla account. I have since noticed that on my personal computer it says "Account disconnected."

I'd like to sign in again and sync them so that I always see the same settings, shortcuts, open tabs etc on both computers. But if I sign in right now, will I lose the customizations I've made on the work computer? Which computer will it consider to be the "source" of the newly synced information?

I have been told to disable my ad-blocker by some commercial web sites and I understand that. But I am also not seeing charts and other non-ad items on web sites such as this one: https://www.medscape.com/viewarticle/alcohols-health-myth-over-how-tell-patients-2026a1000map?ecd=wnl_tp10_daily_260703_MSCPEDIT_etid8475291&uac=146695DK&impID=8475291. I don't want to change my default browser but this is a recent development that seems to be impairing my viewing of pertinent items placed on legitimate web sites. Could you please tell me how to adjust my browser settings to stop this from happening? Thank you! Best regards, Bill Strike

I changed ISP's this week and my computer connects via Ethernet cable through my router. I have no real issues accessing the internet. But after waking from sleep or restarting, Firefox displays the network login prompt. How do I get rid of it? Thanks.

Subject: Firefox Sync appears to have erased all bookmarks after setting up a new Windows installation

Hello Mozilla Support,

I believe I have encountered a Firefox Sync issue that resulted in the loss of my entire bookmarks collection.

Here is exactly what happened:

I have been using Firefox Sync for several years without any issues. This was not my first Windows reinstallation. I have restored Firefox through Sync multiple times before. Firefox Sync had always synchronized bookmarks, passwords, history, extensions and open tabs correctly across my Windows PC and Android phone. I had approximately 350 bookmarks, organized into folders. Timeline Yesterday I performed a clean installation of Windows 11. I installed Firefox 152.0.5 (64-bit). I signed into my existing Firefox Account. I did not immediately enable Sync, so nothing was synchronized at that point. Today I enabled Sync and waited for the synchronization to complete. Passwords synchronized successfully. Browsing history synchronized successfully (it took a little longer). Extensions were restored successfully. Bookmarks never appeared.

Immediately after noticing this, I checked Firefox on my Android phone.

At first, one of the bookmark folders still showed that it contained more than 300 items (I saw the item count), but when I opened the folder it was completely empty. After synchronization finished, all bookmarks disappeared from both devices.

Additional information Browsing history is still present. Saved passwords are still present. Extensions are still present. Open tabs synchronization continues to work. Bookmark synchronization is enabled. I am signed into the correct Firefox Account. The second local Firefox profile is empty. The automatic bookmark backup now contains only the current state (7 items), indicating that the original backup has already been overwritten. The current profile contains both places.sqlite and places.sqlite-wal. The only Sync error log is related to a temporary DNS lookup failure (NS_ERROR_UNKNOWN_HOST) and contains no bookmark synchronization errors.

Because history, passwords and extensions synchronized correctly, this does not appear to be an account or authentication problem.

What concerns me most is that I briefly saw the bookmark folder still reporting over 300 items on Android before it became empty. This makes me suspect that something went wrong during bookmark synchronization rather than the bookmarks simply never existing on the server.

Could you please advise:

Is there any server-side recovery or investigation that can be performed for Firefox Sync bookmark data? Are there any diagnostic logs that I can provide? Is this a known issue with Firefox Sync after connecting a newly installed device?

I would greatly appreciate any assistance, as this bookmark collection had been accumulated over many years.

I have a Sync error log available: error-sync-1783454370913.txt

It only contains a DNS error related to tabs synchronization: NS_ERROR_UNKNOWN_HOST

There are no bookmark-related errors in the log.

Thank you.

Has Firefox's interface gotten smaller? The tabs and search bar are much more difficult for me to read now, and the symbols are extra tiny. I cannot figure out how to enlarge them, since zooming in only affects individual web pages. I tried looking in Settings, specifically the Accessibility section, but I cannot find a way to enlarge this part of the web browser. Help!

I'm on Windows 11. After I added some plug-ins and extensions to replace the ones that went missing during your last update, my bookmarks also went missing. (They were there before I replaced the plug-ins and extensions.) I followed your instructions on how to access my bookmark back ups, and found them. However, everytime, I tried to install one of the backups, I ended up with no bookmarks at all in Firefox.

Please help, I have no access to any of my accounts!

Thanks,

Charlotte

Before facebook using reCAPTCHA I can easily logo in my Facebook and Instagram account, but now I always failed to pass the reCAPTCHA， I report this to Meta no good reply. Only today I did the reCAPTCHA and then got a reminder that facebook cannot detect the reCAPTCHA. I still cannot logo on to my facebook and instagram account due to reCAPTCHA. How can I solve this problem. Thx

For some reason firefox uninstalled on my computer, I genuinely do not know why. When reinstalling it, I have an old save from my backup of that morning (I have it setup that way). However, I do not remember this password whatsoever and I am freaking out a little bit since I have information on there and I am just trying to get it restored onto my account.

Any help would be appreciated.

Starting today (7/8/26), Firefox opens with a "cannot connect" message, have tried multiple online suggestions including downloading and "reinstalling" but nothing works

Hi team,

I am facing a persistent video playback issue specifically in Firefox (latest version), while the exact same stream works perfectly fine on Google Chrome and VLC player.

When I try to play a high-definition HLS live stream from my network provider site (vraitv.com), the video stalls and buffers every few seconds. Upon inspecting the Firefox Web Developer Console, I notice frequent NS_ERROR_NET_TIMEOUT errors during the loading of .ts video chunks, along with occasional CORS warning flags.

I have already tried the following troubleshooting steps:

1. Disabled Enhanced Tracking Protection for the site. 2. Started Firefox in Troubleshoot Mode (Safe Mode) with all extensions disabled. 3. Cleared all cookies and site cache.

Unfortunately, the issue persists. Are there any hidden settings in about:config (such as modifying network.http.max-persistent-connections-per-server or increasing the media cache size) that can optimize how Firefox handles concurrent video chunk loading?

Any technical guidance would be highly appreciated.
