For the last few days after an hour (or so) of use, browser windows try to load but don't finish. I checked the Mac activity monitor and see that FirefoxCP webextensions is hogging memory--8GB! MacOS 26.6.2, Firefox for mac 154.0.1. Did the same thing for MacOS26.5.2. Is AI doing in performance? How can I find what to turn off?

Whenever I turn the free 50GN Firefox VPN on, regardless of the set VPN location, my connection immediately cuts. I've tried refreshing Firefox, raising and lowering my security and DNS over HTTPs settings, clearing DNS cache, and updating Firefox, but none of these attempts fixed it. I can tell its the VPN since everything will load again after I turn it off.

When I had my DNS over HTTPs set to default, it used to say I was connected to cloudflare, but after trying the VPN with it set to off or custom, it now says "DNS over HTTPs is off" when set to default. When I turned on the VPN while the default setting was on, it gave me an error message regarding cloudflare that I can't remember or recreate now that the "DNS over HTTPs is off" at all times. It will only say I'm using cloudflare on the custom setting.

I had a similar issue to this issue a couple months ago, but I resolved it by putting my security settings to default. This time, it seems to be a bit more complex than that.

Hi Mozilla team,

I’d like to report a serious issue with Firefox lately. The browser has been performing very poorly and frequently becomes “Not Responding.” In many cases, websites fail to load properly or get stuck indefinitely, even though my internet connection is working normally.

I’m experiencing these issues on the latest version of Windows 11 with the latest version of Firefox. This has become quite frustrating and significantly affects my daily browsing experience.

I hope the Firefox team can investigate these stability and website-loading issues and provide a fix soon. Firefox used to be much more reliable, but recently the overall experience has been very disappointing.

Thank you.

PLEASE HELP!

Started OBS Vitrual Camera option. in Firefox the camera is no listed.

https://webrtc.github.io/samples/src/content/getusermedia/gum/

only shows phyiscal cams.

How can virtual cameras listed in Firefox?

``` $ v4l2-ctl --list-devices --all OBS Virtual Camera (platform:v4l2loopback-000):

       /dev/video0

SandbergCapture: SandbergCaptur (usb-0000:07:00.0-1):

       /dev/video1
       /dev/video2
       /dev/media0

```

but OBS Virtual Camera is not listed

The recent changes to the right-click menu on YouTube are a backward step. The menu is now cluttered with options I don't use, while the useful “Open in New Window” option has disappeared. I regularly use this function and having to use Shift+click instead is unnecessarily inconvenient. Please consider restoring “Open in New Window” to the context menu. Not every new feature is an improvement, and sometimes the simple, familiar options are the ones users actually want.

Can you please enlighten me on the internal protocol FF follows when downloads are set to "Always ask you were to save files"? I want that dialog to always default to the previously used folder, but it only does that about 70% of the time (in my guesstimation). The rest of the time it randomly decides it doesn't want to do that and it will pop up the Windows Downloads folder instead.

Sometimes it will do that even right in the middle of a mass-download session where I'm downloading, say, 15 items, doing the right-click/save thing, and after 10 items in which the Save-to dialog has defaulted to the folder I want, it will suddenly decide that it wants to go back to Windows Downloads, and because I'm on autopilot with my keystroke routine, I might go through all 5 final downloads before I notice that it's not saving to the right folder anymore. This is EXTREMELY annoying.

What prompts my current post is that I've just started another session of about 10-15 downloads, but this time I'm five files in and FF is still refusing to default to my desired folder. It's not uncommon for it to take two tries before the folder I want sticks, but not five. It's now officially way uncool to continue navigating there every single damn time.

So please tell me why this happens.

And no, please don't recommend that I temporarily change the default downloads folder and just set it to permanently download there, then change it back to "Always ask" after each session. First, that's an unworthy kludge. Second, I always change the filenames of downloaded files--if nothing else, I always remove underscores or spaces to conserve filename length because I've been severely bitten by that limitation once too many times. Therefore I must use the "Always ask" dialog. It's why I don't usually use Downthemall, fab piece of software though it be.

TIA. NB: https://support.mozilla.org/en-US/questions/1591345 is a similar question but answer offered no help. Also after 5 more file downloads during my current session in which FF continues to never default to the previously used folder, I've just given up and stopped downloading for now.

I am trying to restore my firefox bookmarks and passwords from a back up I saved. I am signed into firefox in my browser, I go to restore back up and firefox restars and my bookmarks appearm but I'm signed out of firefox. When I sign back in, my profiles and bookmarks disappear?

You used to be able to view all of your synced tabs from other devices by going into the toolbar menu > your profile > the device name but I went in today to pull a tab from my phone onto my laptop and it only shows about 5 tabs total. You have to click "see all # tabs" which then opens in the sidebar of the browser. I hate the sidebar, it just does not work well with my brain/visualization needs, and have been doing everything i can to avoid it. Is there a way for me to revert the display settings of synced tabs specifically? As I use them frequently enough that I am going to have to look into changing browsers if I continue to have to utilize the sidebar

Bonjour, firefox fonctionne mal avec certains sites et notamment sur le site caradisiac.com très souvent la barre des menus de ce site ne fonctionne pas alors que si j'utilise safari ça fonctionne normalement. je précise que j'utilise un Mac mini M1 à jour et firefox à jour avec l'extension ublock origine même en désactivant ublock cela ne fonctionne pas que se passe-t-il ?

Starting 2 or 3 days ago, Firefox began displaying PDFs incorrectly. The problem is that a single letter is omitted here and there. In the attached screenshots, the first one shows the word. "Department" with amissing letter "t" in the middle. After refreshing the screen, the PDF displays correctly, as shown in the second screenshot.

This is occurring on a Mac; it does not seem to occur on a Windows desktop machine.

I am running Firefox Desktop 155.1 on MacOS Monterey 12.7.6.

After the last update, shortcuts disappeared from the Home screen. I tried adding them manually, but nothing happened.

After a update 154.0.1 and 155.0.1, 64 byt Firefox dod not keep the open tabs once started, but the bookmarks. After searching in Firefox help, neither I could not find a previous bakup folder, before the update data, so I cannot restore the history it manually, so I do not know what to do. It is quite dissapointing as I had dozens of tabs open for diferent putposes, and now I have no one

bei Ebay werden die angebote falsch angezeigt, zum bespiel kann ich nicht sehen da eis ein Preisvorschlag ist. nach löschen der cookies auf der seite ist die ansicht richtig und wenn ich mich eingeloogt habe ist wieder alles falsch, echt nervig.

Hello, Since this morning after an update of firefox the history is lost and my personal bar where I stored my bookmarks is empty now after applying version 155.0.1 the problem is still alive Help Please

Hi a few days ago I updated my firefox version 155.0 well I had 3 open tabs going back to and forth to different sites. when the update firefox popped up, I mistakenly hit update & a notice said firefox is attempting to save these sites, I closed the notice then shut down my laptop,

I never take a update with any thin running. when I turned on the w-10 lap top seem to take awhile to load, so I let it load, and then I shut it down completely. I went to task manager and my read write on my c: drive was running at 100% for about 15-20 minutes. I went to firefox settings and re-set "cache at startup"

This seemed to help some, but still not sure if it is locked in a loop, looking for those those saved files.

I am 80 now and not a pc savvy as I was. not sure what the normal time the c drive for read write should stay at 100% after starting my laptop, I know there is indexing going on, but I thought it would be done by now. after. Thank You Gary Kouri

FF 154.0 will not create a backup file. Trying to create an initial backup to my D: drive (2 TB Samsung 990 Pro M.2 Gen 4 NVMe SSD with 86% free space). WIN Pro 25H2 Operating system, Intel Core i7-14700K CPU; 64 GB DDR5 - 5600 MHz Corsair Vengeance DRAM.

No matter what I do I can't get the initial backup to complete even though the D:/Restore Firefox folder was created. I consistently get this message, “Hmm, there was a problem with the backup. Please try again in a few minutes.” The message result of browser.backup.backup-debug-info is:

{"lastBackupAttempt":1787153673,"errorCode":9,"lastRunStep":13}
