Firefox Support Forum

Hi! I have an issue where my Firefox is opening multiple processes in my task manager. I am used to seeing 7, sometimes up to twelve if I have a bunch of tabs open, but for the last week it has now been spiking anywhere up to 25-30 being open in the task manager (and I will usually at the very most have 5 to 7 tabs open-TOPS!). My memory has been spiking to upwards to 30%, which is causing a slow down in my machine.

I have tried to shut down any extensions that I thought were causing the issue (Ghostery among them), but nothing changed.  I recently put Ghostery back on, and am about to try turning off Adblocker plus.  

When I looked at if I had any other hidden extensions, I saw that I have DuckDuckgo? ebay? and Bing? apparently on the extensions, but when I go into Firefox to remove them, they don't show up in the lists to turn off and on (I don't even use any of those as far as I know, so I don't know why they are even there).

I use Avast antivirus, and it hasn't indicated that there is any virus, but then again, I suppose a good virus would know the work around.

I am not really computer savvy, so perhaps I am making a mountain out of a molehill? If not, please help. This is very frustrating seeing so much memory go to Firefox!

Hi

I would really appreciate any help as I am at my wit's end. Until yesterday I could use Firefox normally on a Windows 10 computer. But since today, all websites have failed to load, and I get a PR_CONNECT_RESET_ERROR message on the screen. However, other browsers seem to have no problem (I'm writing this using Chrome). I have already tried all the possible solutions listed here https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can to no avail. I tried connecting to another network, and it still failed to load any website and kept returning the same error message. I have already tried uninstalling and reinstalling Firefox, and the problem remains the same.

I am a huge supporter of the browser and would hate switching to another option, but I do not see what else I can do to solve the problem.

Thanks in advance!

I get this error message and then it shuts down if I don't stop it by deleting it....

“Error while installing” :Expecting value: line 1 column 1 (char 0) Fire Fox then shuts down if I don’t delete it.

Since the last update various programs we try to play on ITVX.com hang Firefox. Again tonight we ended up having to switch to chrome which behaves ok. End up having to crash FF from Task Manager.

After a mistaken forced restart (inadvertent pressure on the shutdown/start key), one of the 3 windows I had open is invisible. It shows in the 'Windows" menu as one of 3 but when I select it - nothing. It does not show as a recently closed window in History. I have restarted Firefox multiple times, including deleting the xulstore.json file then restarting (a fix from another similar thread).

How can I restore this inaccessible window?

Thanks

I noticed with yahoo finance, and possibly another site or two I do not recall, that firefox becomes unable to open any other URLS and seems to lock up after visiting one or more of my saved favorate/bookmarked Yahoo Finance Urls.

I found a solution that works here...

https://support.mozilla.org/bm/questions/1349884#answer-1441665

The solution is not permanent and has to be applied everytime I open firefox and visit a site that causes this problem. It does NOT seem to affect M.S. Edge at all.

Is firefox / mozilla working on a permanent fix for whatever causes this issue?

Windows11 Firefox 111.0.1 (64 bit) intermittently stops loading page while scrolling. Won't refresh or go back to previous page. No error message. Have to restart Firefox.

Please read this carefully before commenting to me. I do know some things about computers. And no, I will not get windows 11. I am very happy with windows 10 still. After the recent update I can no longer watch videos outside of Youtube. This is very annoying. I am getting error: 232011. I have gone into the Settings: Extensions and Themes: Extensions: No add ons turned on. I have deleted my cookies. I have reloaded, I have rebooted my computer after deleted cookies. It still says error 232011. This is my ONLY computer, no I cannot check this site on another one. No, I cannot check this site at the local library. Anything that is not Youtube that has videos gets block there at this time. I have no idea why, nor do I care. I have my own computer for this reason. However, I cannot use it if I keep getting this error.

i installed the latest version from the website, and it only opens for a split second before it crashes. no error message, it just closes before its even fully open. same thing in troubleshoot mode: the troubleshoot mode popup only appears for a second, i dont even have time to read it before it closes. no error message. i tried a clean reinstall and nothing changed. i opened it in safe mode and it worked with no problems. i read that there are sometimes issues with avast, which i used to have, so i deleted the residual files i found in AppData and Program Files. still nothing. now the only antivirus/firewall software i have is windows defender (and i know that because windows defender keeps telling me haha), and i tried adjusting the windows firewall- still nothing. i would love to include a crash report ID, but there are no crash reports in the folder (photo attached), even though ive tried to open the app half a dozen times since reinstalling.

not sure if its relevant, but just in case- when i couldnt open the version from the website, i tried installing it from the microsoft store, and it actually worked fine at first. but shortly after i finished setting it up (it was probably open for less than an hour), it crashed and then it was the same- crashing immediately upon startup. i have since uninstalled it, in case they were interacting in a weird way, so now i only have the version from the website. i also have the mobile app on my phone and it works like a charm.

i consider myself pretty good at troubleshooting, but im completely stumped here. sorry for the long post, any guidance would be greatly appreciated

Hi

I want to clear data but the only option FF is offering is with cookies. I want to delete all but cookies.

Here it only says Cookies AND Site Data. But I want Site Data without Cookies. Can I somehow manually delete those files? Or manually selectively empty some tables in SQLite databases that FF uses? If yes then what files/databases exactly?

Firefox quit working. when I click on the Icon on my computer desktop I get the following pop-up window. Windows cannot find ‘C:\Program Files\Mozilla FirefoxFirefox.exe’

When I click on the Icon in my taskbar I get this pop-up window . Windows cannot find ‘C:\Users\hgmv8\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\Taskbar\Firefox.Ink’ Make sure you typed the name correctly, and then try again.

I have downloaded the latest version of Firefox but still get the error messages

In the last 4 days Firefox is constantly freezing on the Tile Pages of multiple streaming sites. It becomes non-responsive, and won't let me reload or use the Home button. I have tried turning off hardware acceleration and clearing the cache and I still have the same issue.

When DNS over HTTPS is not enabled in Firefox and I set network.dnsCacheExpiration to 600 seconds, evidence from about:networking#dns shows that the minimum DNS cache expiration time is indeed 600 seconds. However, when I enable DNS over HTTPS and set network.dnsCacheExpiration to 600 seconds, the network.dnsCacheExpiration setting seems to be ignored. New DNS cache entries are able to have far less than 600 seconds to expiry. Why is network.dnsCacheExpiration ignored when DNS over HTTPS is enabled? Could this be a bug in Firefox?

I am using Firefox on Ubuntu 18.04 (current release 111.0, but the problem has occured over the last two releases). I like to open the individual page from a Youtube playlist so that if I get distracted, I won't lose my place. I do this either when disconnected from the internet or using the "work offline" feature. Previously firefox would show either "Problem loading page" or "Serve not found," but now it keeps trying to load youtube which sucks up time, cpu, and memory.

These are pages that I have never been to before so there should be no record in history, but even so I have tried clearing my history and this did not help. I have tried a bunch of other sites, but Youtube is the only site that I have seen this behavior on. Attached is an example (The google page and the first youtube tab were loaded online). The shown youtube tab (second tab) and a random webpage from google (last tab) show this behavior.

Could you please help me.

None of my bookmark functionality is working. I have restarted Firefox and cleaned out all extensions etc and so doing have discovered it's only when I reinstall Last Pass that the functionality stops.

Is there any known fix for this, or can I simply no longer use both Firefox and Last Pass together?

Thanks

Hi, using firefox for a long time. 2-3 days ago FF started to start slow. If I open FF, it shows me FF GUI without any icons and after 3-5 seconds it starts completely.

Tried to disable all extensions (bitwarden, ublock, easy screenshot, feedbro), same result. Tried to clear cache, cookies, history - same result. At the end I made a reset of firefox via menu, same result. FF is latest version.

See screenshot - this is what I see after start firefox (for about 3-5 seconds) Any idea / fix please?
