How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

Firefox keeps reminding me that updates are available. I download and it says its installing but it doesn't seem to update. I have tried closing Firefox before running the installation but it makes no difference. I am on 125.02 at the moment.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

Opened a directory of pdfs from the command line using ```firefox * &``` and went on with my work. Checked the terminal to see these error messages: ``` [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e75431700 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e79a87a00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e84e52400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 ``` I tried recreating this error by restarting the entire process and repeating everything, but to no avail. I'll try to recreate the error a few more times, however if I don't post a message it means I was unsuccessful.

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

When I try to use needed tools on websites, Mozilla is blocking the page from opening. USPS will not allow me to track a package. When I enter the tracking number, the page just sits on white and the search just spins

Hello, since the latest version of Firefox, as always, it breaks now if I want to enter instantgaming or it does not enter no matter how much I click on enter or in kinguin.net, when it asks me for the recapcha, it stays in an infinite loop and does not show the images. .

I have done safe mode and installed firefox from 0 and nothing, it is tedious that at this point a browser that has been having this type of problems for years because in opera, edge they do not give me these errors, it is tiring to always have to have a browser that fails due to anything.

I look forward to your help, thank you

Hello Support, 5-1-2024 First Time in a decade I've had to contact support. Please TELL me why there are 13 instances of firefox running at the same time. It is take so much memory up and really slowing my machine down on the internet also. Tell me how to fix otherwise I will have to switch to a different web browser. I realy love firefox and have been using since It was released. I really Don't want to switch Browers but this is to much any more. It has become much worse than a Year ago. I do Not have any addons or extension installed now, I don't use them enough to install. Thank you for your help in this BIG HOG memory problem.

Lately, when I'm on a website and click into an article to read, suddenly the McAfee anti-virus ad or whatever you call intrudes and takes over the browser page I'm on and won't allow me to navigate way or stop it unless I close the browser tab and/or navigate away from the page all together.

Why is this happening? Is it something in the my particular browser? If yes, how can I remove and prevent this from happening?

Is it something that is occurring on the server of the site I'm visiting? Should I notify them what is happening?

Any help and advice greatly appreciated. It is very annoying. I don't have McAfee installed and it's not a pop-up, it happens within the browser page itself.

Thank you,

Marty

So I noticed an issue with certain websites a few days ago. I was trying to make a hair appointment online, it was asking me to fill in my email, and the box wouldn't let me click on it. I used a different browser, and it worked just fine. Same thing today: I was trying to make a lab appointment, the next step was verifying I'm not a robot, I clicked the box, and it had a loading circle eternally. I tried it on a different browser, and it worked within seconds, no loading. I've never had this issue with Firefox before! I tried clearing my cookies and cache, and that didn't do anything unfortunately. Let me know what I can do to fix this problem! I normally loved Firefox and it's my main browser, so I'm hoping to resolve this issue. Thanks so much!

I want to delete firefox logins info and to make sure passwords and logins are never stored. I go to passwords, open up menu, and the "remove all passwords" choice is greyed out. How can I get that choice it be valid and to impliment that operation?? And to never have these stored??

I've reported these issues before with no response. I've uninstalled reinstalled cleared cache and cookies searched another forums et cetera. Why must I manually update when it's set to auto update? When I set controls to ask where to download items it bypasses that and downloads it as a temp file where I have to cut it out of explorer and paste it where I would like to save it.

I would like to be able to make sure if a pop-up window is blocked, that I'm being notified about it, but there are no options in settings.

I read through the instructions listed on the help pages and found a message from support from 4 years ago about manually editing the settings, which wasn't helpful.

Are they just on by default now? Or did they get turned off and if so, how do I turn them back on?

(p.s. having something teach you how to do something, this case getting trouble shooting data manually, should open another window, not navigate me away from the page I'm sending this message from)

Every time I open Firefox another blank window opens behind the main Firefox pages . I see it when I close Firefox so have to close that too. There is no URL in the window just a blank page.

I am able to start FF with no problem. I open a few tabs and then without warning I can't access any of the sites without closing FF and restarting. Then the whole cycle is repeated. I am considering getting rid of FF this started just over a month ago.
