My phone carrier alerted me that my 15gb of data had all been used up, which was surprising considering I've been mostly at home on Wi-Fi and don't ever reach my limit even when I'm traveling.

I looked at what was using the data. To my surprise, it seems like Firefox Focus had inexplicably burned through 10gb (!) of data in the background over the last day without any tabs even open.

Has anyone else had this issue? Is there an explanation for what's happening?

I'm concerned about it continuing, obviously, but also concerned it might represent a security breach on my phone somehow.

In the meantime, I've disabled the Firefox Focus app's permission to run data in the background. Not sure if that will solve the issue. I also noticed that it does not seem to have been burning data on Wi-Fi.

Thanks for your help.

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me Please? And if possible please give as many solutions as you can find or know so I can implement them quickly.

When playing videos in various websites (Jellyfin, Mastodon, Youtube) hypridle is receiving many 'ScreenSaver inhibit' messages that are never cleared.

A similar topic pointed to dom.screenwakelock.enabled being the culprit and disabling that fixed that users issue. But I've done that and the problem persists (It did remove one extra lock, but that was the one that was getting cleared.

Chromium sets and clears 1 lock correctly.

System: NixOS unstable DE: Hyprland

I'm using `exec-once = hypridle >> ~/log.txxt` to monitor the logs.

This behaviour is new in the last few months.

It is only present on one of my two systems that is very similar, they both use the same nixos config. The one with the issue is a i5-4590S based system with no external GPU, the one that doesn't have the issue is a Ryzen 7 5800X3D with RX5500. But that may be a red herring, I don't always update the both at the same time, so they may have different software versions.

'Linked In' technical support are telling me that I am unable to see certain pages on their system most likely because my Firefox Browser (which is fully up to date) is using DNS. They said to remove DNS. Is this wise advice and if so how do I do that and what difference will it make to my day to day use of firefox?

I’ve noticed that Firefox is draining my Mac’s battery significantly often consuming over 200% of the device’s power. It also prevents my Mac from going to sleep when not in use. Is there a setting I can adjust to improve battery efficiency and ensure that Firefox doesn’t block my device from entering sleep mode? I’d appreciate any guidance to resolve this issue.

My Firefox on windows 10 crashes tabs OFTEN. Mostly is seems to be Facebook and YouTube tabs, but other tabs will crash and this morning, the Firefox start page tab crashed. I've done "refreshes", I've uninstalled and deleted the folder and re-installed, I've checked the SSD for errors. Nothing appears in the event viewer. Is there some way to definitively figure what is causing this?

For the last few days when I am on the web using Firefox, my android screen is displaying large print - like it is zoomed in. There is no way to fix this. Assuming this is a result of your last fix/update. This needs to be addressed. This is not an issue with any other browser

When on a web page or e-mail I regularly get a spinning multi colored ball which stops/interrupts the loading of the page. It will last for 3/4/5 seconds and then stop. What's up ??

How to I delete three Fire Fox icons found in Apps? Two show up in the taskbar tray and I am constantly being asked if Fire Fox should be my Default.

Also, refreshing Fire Fox changed all my options. For example, when Fire Fox opened, there were two rows of internet choices from "mail" to "dictionary"; now, a plain white screen.

I'm about to give up on Fire Fox and follow the herd with Microsoft forever! It seems every time Microsoft has an "update", two things happen: I have problems with Fire Fox and my phone rings off from folks I've never done business with; any connection?

Thanks in advance for your help. Computers are a necessary evil!

Recently Firefox has been randomly crashing the past 3 weeks multiple times, Is anyone else having this odd issue ? I'll be watching a stream or youtube video and bam out of no where the Browser goes black for like 20 or 30 seconds then crashes. I sent in about 3 crash reports and wondering if the Firefox team is aware of this issue.

All of a sudden, when I'm on eBay, a lot of the hot links, embedded on an eBay "for sale" item don't work. Sometimes, when I (repeatedly) hit "Reload Current Page", they start working, or become "hot", as they should be. I wrote eBay, but no response. I don't know, if it's their problem, or something wrong with Firefox. Thanks, in advance, David

I view movies and tv series on Amazon Prime and others every night . Suddenly I no longer can. On Prime I get a msg. saying I must update ff. It tells me the process and I have done it at least 6 times. When I go to 'about Firefox it tells me that I am already up to date, have version 115.18 esr. I am on a Dell Business computer, Vostro 470. Windows 7, service pak 1. Processor is i5-3450CPU @3.10GHz. RAM 400 GB , 4 processor cores. 64 bit. Prime disk466 GB 395 GB free. I'm a senior lady, not very computer literate. I have a ton of duplicate files but don't know which to remove. If I got help I could free up a lot more space. I watch everything on my computer monitor. I don't understand as the esr was supposed to allow us to continue. Please help as I am pretty homebound and this is about my only entertainment.

For any page I've tried under nationalrail.co.uk, Add to Home screen no longer offers a way to change the name of the icon so every one is National Rail (see screenshot). It used to work as expected, an icon with a default name which can be changed but now it has the instruction Touch and hold an icon or tap Add to add it to the Home screen with the site's icon and no edit field.

bbc.co.uk is similar but cnn.com is fine.

I cannot click links from google search on Firefox (latest version - Windows 11) if they are an advertisement. Even an ad from Amazon from my search results. Example: I did a google search for scrapbook paper from a specific company. Google gives me a page of search results. In the top of the page are adverts from Amazon etc. One of them was one I clicked on for amazon. See screenshot 1. When I clicked on the one circled in red I got the second screenshot as a result. So then I clicked the exclamation mark next to http: on screenshot 2 which gave me this info in screenshot 3. I went back to the google search page and cannot open a one of those ads across the top. My husband has the same issue on his galaxy S7 tab and he hates not being able to compare prices by clicking those ads. I have on my desktop, as well as his tablet the browser privacy set to Standard. So what is causing this? I used to love firefox but these latest 3 or 4 updates have left it a hot mess. How do I fix this? It is not like this with other browsers. I have no issues with then at all. I have the same tablet as him, but it has not updated to the latest update and I am able to click those same links from it. I just ran the same search from my galaxy mobile using firefox 119.0.1 It works fine on the mobile version I am running (I know but this is why I won't update it!). Please tell me, help me figure out what is going on with this version of Firefox (version 132.0). Is it FF and google not playing well together or just a FF issue because as much as I like FF I am about to dump it for a browser that works. Just for GP, I only have Last Pass extension active. I have AdBlocker Ultimate but it is currently disabled as I thought it was the culprit and have not re-enabled it just yet. All those extensions listed in troubleshooting information I assume is things within the browser itself?? As I said I only have one extension active and only 2 installed. Please advise. Thank you.

When I turned on my laptop today my Firefox browser started running an update when it was done I could not open the browser. I get two messages.

  firefox.exe-Entry Point Not Found ----The procedure entry point
      ?toString@Decimal@blink@@QEBA_NPEAD_K@Z could not be located in the dynamic link l. 
        library C:\Program Files (x86)\Mozilla Firefox\xul.dll.

I'm sending this from my tablet because can't form my laptop.

After I upgraded my system to Kubuntu 24.04 thunderbird started eating CPU (150+% CPU usage according to htop). Because I couldn't tell if the culprit was the new KDE or the old profile, I tried to create a new profile, blow away the KDE config, etc. I also tried downloading the latest version of thunderbird from the website. Nothing helped.

I was able to replicate this problem using the in-memory, fresh KDE.

To replicate: Create Kubuntu 24.04 install USB. Boot from this USB. When asked to install or try, select "Try Kubuntu".

Start Thunderbird.

When prompted to create an account, select cancel. Go into settings, to the bottom, and select Maildir for file storage. Quit thunderbird, and start it again. Create account (select configure manually, enter the information for imap and smtp host, STARTTLS, detect authentication. My username does not contain an @, if that makes a difference). Select "Re-test"

Try to read mail. You will quickly notice that Thunderbird is consuming > 100% CPU, and UI is non-responsive.

Restarting thunderbird does not help.

netstat -tupane shows one or two connections to my imap server port 143, but wireshark doesn't show any traffic on port 143

Not that I think it matters (since I can't get Thunderbird to start seriously downloading from the server) but I have a big ( >100G) Maildir behind my courier server.

Note that I see this problem both with the version on Kubuntu 24.04 install USB, and the latest version downloaded from the thunderbird website.

You folks updated Firefox and now I can't open earmarked accounts. Reading all of the reasons is not helping me. I am not computer literate to fool around with settings. So can I go back to old firefox.

I feel rather obtuse asking, but how do I get my Thunderbird addressbook to sync to gmail contacts? I uninstalled Cardbook, because Thunderbird now does CardDav, I treid to create a new CardDav addressbook by opening my addressbook, selecting new addressbook, and going through the steps to give Thunderbird access to my Google account. But,

  no new address appeared in the list of addressbooks, and 
  the option to create a new addressbook is no longer avaiable/showing.

Addressbook is still not syncing. My server settings are IMAP. I still have three address books: All, Personal, and Collected.

I am flumoxed. John
