Firefox Community Forum

Hello! I just noticed that when I type a keyword related to one of my bookmarks into the address bar, Firefox suggests the bookmark to me—and also, my pi-hole query log shows queries being sent to that domain, even if I don't visit the site.

Is this normal? I'm confused as to whether I should have expected this. I had assumed everything related to bookmarks was stored locally. What information is being sent and requested when this happens? It feels like it could be a potential privacy issue to me, but hopefully I am misunderstanding something!

I run Ubuntu Mate. But versions later than 20.04 of Ubuntu Mate do not provide color support for my Samsung CLP-620. And, I can't install your latest MozillaVPN version on 20.04 because it requires libssl.3 (I think that's the designation) which is no longer available for 20.04. So, I am left with the choice of (1) no MozillaVPN but a color printer; or (2) no color printer but MozillaVPN. I have multiple computers so if you can't tell me a way to get both (MozillaVPN and 20.04), I'm stuck with a conundrum and will end up dedicating one expressly for printing when I need color -- what a waste!

Note: I know 20.04 is history but I can live with it if I have to rather than junk a good printer.

I hope you can help.

All the best. Thanks for all you do.

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

I recently upgraded from Ubuntu 24.04 to 26.04, using Mate Desktop and Compiz compositor. I am using Firefox from the Mozilla Team PPA, currently 150.0.1. I am running custom kernel built from upstream source, currently 6.18.25. Hardware is a home brew CoffeeLake machine, i7-9700k, 64G of RAM, 2TB WD Black SSD and many TB's of spinning rust, graphics is Intel ARC B50 Pro, ASUS XONAR SE 5.1 Channel 192kHz/24-bit Hi-Res 116dB SNR PCIe Gaming Sound Card. Prior to upgrading Firefox was not 100% occasionally tabs would wedge, now if I get two hours I'm doing good, I've tried disabling extensions and plugins no help. Tried with and without hardware decoding, worse without but bad no matter. Any suggestions how to get stability back?

• • Background:**

I'm a senior software engineer running Firefox Developer Edition on a Linux machine with 8GB RAM. I have Fission architecture (site isolation) enabled, which I understand is now the default since Firefox 95+.

• • The problem:**

When I open 20 or more tabs across different domains, Firefox's memory consumption scales dramatically — often reaching 4–6GB of RAM for what should be lightweight browsing sessions. This is significantly higher than what I observed before Fission was enabled.

• • What I've already tried:**

- Disabled hardware acceleration → no significant improvement - Set browser.tabs.unloadOnLowMemory to true → partial relief

 but tabs reload constantly, disrupting workflow

- Reduced content.notify.interval → marginal improvement - Tested with all extensions disabled (safe mode) → RAM usage

 still high, confirming it's not extension-related

- Checked about:memory → large number of separate

 "Web Content" processes, one per origin as expected with Fission

• • What I'm trying to understand:**

1. Is there a way to set a maximum process count cap for Fission

  without fully disabling site isolation? I found 
  dom.ipc.processCount but changing it doesn't seem to affect 
  Fission's per-origin process spawning behavior.

2. Is browser.tabs.min-warm-process-count a relevant setting here

  and what is the safe range to modify it?

3. Does Firefox have a built-in memory pressure threshold where

  it automatically consolidates processes — similar to Chrome's 
  memory saver — and if so, which about:config keys control it?

• • Environment:**

- Firefox Developer Edition 151.0b10 - OS: Ubuntu 24.04 LTS - RAM: 8GB - Fission enabled: confirmed via about:support - Extensions: disabled for testing

Hi,

I've got Firefox with 4 adblockers: AdBlocker Ultimate, AdLock, Element Blocker and uBlock Origin. Still, https://www.youtube.com/c/franceinfo/live (news channel) sneaks ads before and after the weather forecasts. "C'était la météo avec Florette" (you watched the weather forecast with Florette salad sauce - of course I didn't!).

I can't find how to get rid of it. Please advise.

The quick links on the home page should be exactly for that QUICK LINKS! not for visited sites! also you only have four rows. OPERA have unlimited. To make matters worse, the stupid sites that I visited only once cannot be removed.

Firefox for Linux Mint mint-001-01 150.0.3 64 bit Issues with login on ups.com When I press on the Login radio button I get this:

Access Denied You don't have permission to access "http://www.ups.com/lasso/login?" on this server. Reference #18.e86ac917.1779017770.661111b8 https://errors.edgesuite.net/18.e86ac917.1779017770.661111b8

Works in all other browsers on same system, Chromium, Brave, Opera, etc Works on Windows 150.0.3 64 bit Cleared cache,cookies, disabled all extensions, disabled advanced tracking protection, every suggestion I could scrape the internet for. Ran Firefox logger and it found a 403 error. Any suggestions? about to nuke and reinstall

Is there a way to disable tab groups without going through about:config? Because I can't find it and there really should be...I have no idea how that feature works, I don't want it, but I keep ending up with groups unintentionally. I still don't know how I'm doing it. It's incredibly annoying and apparently incredibly easy to accidentally trigger and I'm sick of losing tab space to these random colored boxes for no apparent reason!

1- I am forced to abandon firefox browser on desktop 2- I wont quit using firefox until mozilla keep fighting against google's discrimination 3- I am forced to see no proper error message 4- No proper reason is told to wait and try later 5- This war wont end

I hate google more than any company in this world.

Now every (not just any random ) video when play for 10 seconds shows me same ugly annoying message

"Something went wrong. Refresh or try again later"

NO refresh works later after one day or even after removing all the history and saved site data. Even re install of latest firefox has no effect on google. Changing user agent is not working either. Tor browser is the only way to watch any youtube video. BIG, GREAT AND MANY THANKS TO TOR NETWORK.

Tor is left for the only way i can have a little freedom to watch youtube videos.

My pain point is that why i am forced to abandon firefox. I have been using it for decades. I love it. Its my best browser ever.,

Why chrome is the only browser to be allowed to watch videos on you tube.

Even safari when used there is always warning saying your browser will not be supported in future.

Google is creating same kind of problems in Android OS too.

My friends, Let me ask, what our future under google umbrella?

I strongly encourage you to raise voice for browsers other than chrome especially for firefox.

I use updates on linux and my firefox is always latest. There is no chance of any corruption or security risk with firefox on linux. Google intentionally forcing me to use chrome.

I want you to help me if have any clue what is going on.
