Forum d’assistance Firefox

So to start with, this is a brand new computer, the video card was out of an old computer but everything else is brand new. Upon installing windows and updating everything we installed Firefox it started for a few minutes then crashed.

After many tries(uninstalling and reinstalling) we find that uninstalling Firefox and installing through Microsoft store it will start once but crash shortly after and will not start again. If we are able to get through to the menu and disable hardware acceleration it works a little longer but will eventually crash and never open again.

Holding down shift will not open troubleshooting mode.

I have updated everything to make sure it is up-to-date, through manufacturers websites. I have gone step by step with every recommended page to try and I still can't get Firefox to start even once now.

I'm sure it is a check box somewhere that needs to be checked or unchecked preventing Firefox from starting, but I am at my wit's end here.

Please help!

firefox is using so much memory that it is causing lag and loading problems.

i know that the root of my problem is that i have an unholy amount of tabs open all the times but if i go into the process manager for firefox i can see that the memory problem is actually usually only 1 or 2 tabs that are using over 1GB of memory. this has only been a problem in the last few weeks so i am not sure if something has changed on the firefox side of things.

I looked into tab unloading and this seems like it would solve my problems. however the unloading process only happens automatically when the total amount of memory that firefox is using approaches the maximum amount of memory you system has available. with 32GB of ram and firefox reaching not even 16GB when completely stretched the automatic process will likely never hapen. yet firefox is still using enough memory that it is causing itself problems.

i dont really want to have to unload my tabs all the time to keep firefox's memory in check. is there anyway to lower the amount of memory that causes firefox to automatically unload tabs? i have seen extensions that say they will sleep tabs that are not being used. however they all seem to just sleep tabs that are not currently in use rather than sleeping tabs that have not been used that day.

i feel like the tab uploader is such a good feature in firefox that i would love to be able to use it to solve my problems. however i am not sure how to make this happen in the laziest way possible.

I have a website that is cached with Cloudflare. It turns out that after updating it I tried to reload the cache by pressing the shortcut key Cmd+Shift+R, but it had no effect, the HTMLs are downloaded but the content remains the same.

In this case I had to directly access the HTML and JSON file that were not updated and I had to carry out the procedure individually for each one, thus reloading their cache, but not for the entire site.

The site only had the files loaded by accessing it via the anonymous tab and then clearing the entire browser cache.

Firefox has stopped saving history and I am unable to save any bookmarks. This seems to have happened recently for no reason I can understand. I haven't made any changes. I use a VPN but was doing so before this happened. I have checked all the settings and also deleted the places.sqlite file. When I click <bookmark current tab> nothing happens and history shows as empty.

Very often, recently, I can't communicate with an organization via their form on the WWW internet. After minutes of frustration, I change to a Chrome or Safari browser on my Mac, and it works just fine.

One of the problems is when filling out a form, Firefox says over and over there is an error. Safari takes that same data just fine, no error.

There are others, but I'll have to wait until Firefox fails again since it's not that easy to reproduce what happened days or weeks ago!

I am trying to use a website (www.gool.co.il) which I use to study and worked for me in Firefox on PC and on IOS a few month ago and now the login is broken in Firefox but works in other browsers is there a way for me to fix it?

Why is mousewheel.with_control.action = 5 not the default in 2024 ? or at least an accessibility features ? I have multiple over the years had to help my older parents with `broken` website due to the actual default increasing the font size instead of behaving as a pinch and zoom

Hello, As of today, my computer stopped loading the windows and tabs which I had accumulated with information I was interested in learning more about. I had 15 windows and sometimes up to 20 tabs saved per window. I had been saving and the computer had been loading these for years prior to today. Did something change in Firefox that these have disappeared from my desktop?

The only advice I can find is at https://support.mozilla.org/en-US/kb/control-whether-firefox-automatically-fills-forms That advice removes the unwanted email address from the current display, but the unwanted address reappears whenever I return to the page.

I have noticed that I am unable to access the comments section on the various web sites I visit. I am sure it's a settings issue, however I have not been able to find the setting section. Any suggestions??

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

Hi - I have been getting printing 'overlaps' for a better way of describing it, and this happens randomly. It happened yesterday and today, and today it was with WhiteStuff.com and Preloved.co.uk. Is that something that I need to fix or is the problem with the website owners? Thank you!

Firefox has an issue with the scroll bar on certain websites which makes it befin flashing and creeping towards the top of the page on some websites (See attached gif). This is particularly an issue on whilst logged into my university study portal.

I have already troubleshooted this by: - Disabling add-on's - Deactivating smooth scrolling - Deactivating auto-scrolling - Deactivating enhanced tracking protection. Nothing has resolved the issue.

On my windows 10 desktop firefox will not work, message ‘Couldn’t load XPCOM’ . How can I get it fixed as I no longer have internet access

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section.

Delete cookies and site data when Firefox is closed tab is checked so it should delete cookies, but it doesn't, and when I click on manage data there are still cookies etc. How can I make this automatically delete?
