Firefox Support Forum

Please my firefox appears to have crashed, or is not working how can i fix it. As i try to open firefox document a dialogue box appears saying that either the firefox is not designed to run or that i should reinstall firefox

I have been using firefox for more than 4 years now. But from about a year, i m facing the issue with the Sudden High CPU usage in Windows task manager.

The task manager has 2 different firefox processes. One being actual instance i am running. and the 2nd being the automatically opened in background.

i have figured out whenever i have active internet connection and my system is on charging the 2nd task automatically starts in background and uses upto 80% of cpu usage. Ending the 2nd task form task manager doesn't affect anything. only the cpu usage drops. Also Closing my firefox instance does nothing to that 2nd task.

I have tried lot of solutions i found on community. Nothing seems to help. problem still persist. I even posted comments on ongoing threads. but no reply from anywhere.

this is the last time i m trying. if i get a solution its good. otherwise i am going to shift to edge. I have no other choice.

Screenshots from multiple dates are attached.

Hello Everyone

In our Citrix environment we use Mozilla Firefox 115.0.2esr (64-Bit). Exactly after 5 minutes the VDA terminates the user session and FireFox is closed. It does not matter, the session is inactive or the user is actually browsing.

The only eventlog is the following: Der Citrix Desktopdienst hat erkannt, dass eine Benutzersitzung beendet wurde. Sitzung 'XXX' für Benutzer 'Username' wurde beendet; Ursache: Logoff.

The Citrix Desktop Service has detected that a user session has been terminated. Session 'XXX' for user 'Username' was terminated; cause: Logoff.

I already started the Firefox with troubleshooting mode but does the same.

Thank you for your help, hope someone already saw this issue

As above,

Attempting to attach any file crashes the browser - Version 116.0.2 (64-bit)

Windows 10 Pro 64-Bit

Any website. File explorer window doesn't even appear. It just crashes instantly.

In your reply to my previous question, I checked with the Bank... their tech people checked it is coming from the firefox Mozilla side of communications. Firefox is stopping the copying process on my browser. Keeps coming up Error- reset tab or close. Mozilla NEEDS to FIX this Problem immediately. It may be time to give up on Mozilla/FireFox. Been there for years, and now having several issues. Please advise?

My M-1 MacBook Pro has been running warm since I installed Firefox 116.0.3 (64-bit).

EtreCheck Pro reports that "plug-in container.app" is a runaway process.

When I show package contents for Firefox, I can see "plug-in container.app" in the MacOS folder.

Will there be an update soon to correct this problem? Firefox is my primary browser. I work in the SaaS industry and have to run a browser 24/7.

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

Facebook - Candy Crush - Win10 PC game image and text is brighter - less vibrant and fuzzy in latest Firefox 93.0 version. Confirmed by downgrading back to 92.0.1 and game was crisp and clear again. Went through all the recommended trouble shooting basics - clear cash and history, check Firefox settings = no improvement. First screen shot below is 93.0 Second screen shot is 92.0.1

I frequently use the site SAM.gov to look at US government solicitations where documents are posted for the public to download. Recently the links to those documents fail to load on Firefox when it did just a couple of weeks or less ago. I am now forced to use MS browser just to see those.

For example go to https://sam.gov/opp/81551b02dd2d4e2b8fc06ce327d57113/view look for "Attachments" about 2/3 of the way down and you can see the circling caterpillar thingie where the links should be.

is there a setting or fix? Thank you in advance

I made a few changes to about:config. How can i save the about:config settings for a new Firefox installation? My bet is this is possible either with distribution-policies.json or with a HTML. I used Kali Linux, this operating system comes with a pre-configured Firefox installation. For example it uses a permanent darkmode with duckduckgo even while cookies are denied. It also comes with customs about:config settings like disabled telemetry.

Those are all the setting i changed and i would like to find out a permanent way to import them to Firefox, right after installaing the Browser. It's time consuming changing each setting manually after each install...

toolkit.telemetry.enabled false browser.urlbar.placeholderName DuckDuckGo app.update.enabled false geo.enable false extensions.pocket.enabled false pref.privacy.disable_button.view_passwords false network.protocol-handler.external.mailto false datareporting.policy.dataSubmissionEnabled false datareporting.healthreport.uploadEnabled false browser.newtabpage.activity-stream.feeds.telemetry false browser.newtabpage.activity-stream.telemetry false browser.newtabpage.activity-stream.telemetry.structuredIngestion.endpoint leer browser.newtabpage.activity-stream.telemetry.ut.events false browser.ping-centre.telemetry false toolkit.telemetry.archive.enabled false toolkit.telemetry.bhrPing.enabled false toolkit.telemetry.firstShutdownPing.enabled false toolkit.telemetry.hybridContent.enabled false toolkit.telemetry.newProfilePing.enabled false toolkit.telemetry.reportingpolicy.firstRun false toolkit.telemetry.server leer toolkit.telemetry.server_owner leer toolkit.telemetry.shutdownPingSender.enabled false toolkit.telemetry.shutdownPingSender.enabledFirstSession false toolkit.telemetry.updatePing.enabled false toolkit.telemetry.unified false toolkit.telemetry.prompted false toolkit.telemetry.rejected true toolkit.telemetry.pioneer-new-studies-available false experiments.activeExperiment false experiments.enabled false experiments.supported false network.allow-experiments false media.peerconnection.enabled false (WebRTC leaks)

If you know any more settings that shuld be disabled, please let me know!

Basically what happens is that some images download and upload as a mess of vertical stripes. One of the images is what happens when i try to change my pfp on my email, and the this (i couldnt get the image to upload here) is what downlaods when i hit share here.

Update to version 96 64-bit just completed. Many websites now experiencing Secure Connection Failed PR_END_OF_FILE_ERROR. Did Help -> More Troubleshooting Information -> Refresh Firefox to go back to all defaults. Open Firefox again, add Menu Bar. Open what used to be home screen tabs, ok at first, but within minutes start experiencing Secure Connection Failed in several websites. Seems to come and go, sometimes a Reload current page restores normal website, sometimes not. Close Firefox, open again, restore previous session tabs, only a matter to time before one or more start getting Secure Connection Failed errors. No extensions, no themes. Browser is now so unreliable as to be unusable. Please assist.

Last night my firefox stopped working. Any time I used a bookmark or typed in a website, it would start to load and just sit at a blank screen continuing to load but not doing anything. I checked in another browser and it worked just fine, so it’s not my internet. I’ve tried closing and re-opening firefox, any time I open it now it says it’s already running and I need to close the previous session. I have tried un-installing and re-installing firefox, clearing my history and cookie cache, and restarting my laptop multiple times but nothing is working. I would appreciate any help with this, thank you.

Hi,

I looked for a solution to my problem, but my issue is that I don't know the technical terms for what is happening. So, I'm sorry if there's an FAQ out there that addresses this already.

The problem is that - Mozilla launches, it lets me type an address, and then... nothing. The dot on the favicon of the tab just goes back and forth forever. Meanwhile, Chrome and Edge work fine, so it's not my internet. In fact, I'm sending this message from Edge.

I tried refreshing Firefox, and then uninstalling completely and reinstalling, and it worked in the beginning, but then the problem came back.

Please help.

Best, Felipe

Thanks for last message you sent via "no-repy".

You ask me questions in those e-mails, but I can't reply.

The last had a lot of if you are running this ..... then this ....

I'm not using Windows XP or Vista!!!

I keep my software up to date.

Well, I guess I have to part from Mozilla. For a long while it was so good, but lately ...
