Firefox Support Forum

Hi I support young people ( aged 7-11) with Dyslexia. they all use Firefox to log in to their lessons. It automatically recognises them and it is a system they are familiar with. All of the lap tops up grade to the latest system automatically. One of them does not work on the new version. The students get a message which says version 78.0.2 is not compatible with 78.0.1 It is a Windows system. This is really distressing for the students using this lap top. They blame themselves for the problems and itis having an affect on their confidence. Can I revert it back to the older version ? and if so how? I really would appreciate some help as my wee students are upset and i don't know how to help.

Hello,

I have been trying to use Firefox and it won't load, the page just doesn't load to firefox. I have Mac OS Monterey 12.0.1. I have deleted the app and reinstalled it but nothing works. Someone, please help!! The browser doesn't work it won't open.

latest version 88.0b6 still gives "can't load xpcom" message why is this still happening after 3 years of the problem in the history of upgrades. Don't tell me to check profile as I can't even start FF. I have done all the deletions as instructed by various experts but still get the message "can't load xpcom". Samuel Santos said download "83" to see if that fixes it I don't know if it did cause I then got "CAN'T FIND ENTRY POINT"

Firefox 87.0 (64-bit) on Ubuntu 20.10 is currently unusable as it won't open anything.

• Firefox opens with no page loaded.
• Clicking the single "getting started" bookmark does nothing.
• Entering a search term in the address bar and pressing 'enter' changes the url in the address bar but nothing is loaded and the page remains blank. There is no indication that anything is loading.
• Entering a url, such as "www.youtube.com", and pressing "enter" does nothing. There is no indication that anything is loading.
• Opening the menu by clicking on the burger icon, then on "preferences" does nothing except make the menu disappear (same with most of the options in the menu).

In the browser console I see some errors and no request info (see screenshot).

I've tried `sudo apt purge firefox` then installing again, which didn't help. The problem started with ubuntu 20.04 (I only updated to 20.10 to see if it might resolve this problem).

I've tried the "refresh firefox" option, starting in safe mode, and clearing the startup cache, which didn't help.

Any suggestions would be much appreciated.

During class today, Firefox unexpectedly crashed on my Windows 10 PC after downloading a pdf file from my History teacher. Now, when I try to open Firefox, a transparent box quickly appears before disappearing again, not opening Firefox. I have yet to find a solution that has worked.

After having installed the latest Firefox update Firefox starts but it does not react to any link inserted for display.

If have tried all three help solutions provided but it does not react, also a new installation changed nothing

The error message is: Starter process deactivated after error.

Could someone please help to make run it again

P.S. It was not possible to get the Troubleshooting information as I could not write this request on Firefox but had to use another browser

Hi! Since about two month I have the problem, that firefox does not update automatically anymore. Every time a new version is available I get the message "Firefox can't update to the latest version" and I have to do full download. Searching the forum did not help solving the problem. Is there any way to determine what is preventing firefox from updating? Cheers Christian

Microsoft/Windows 10 has removed Firefox from their list of potential default browsers. Most information answering "how to make Firefox my default browser" is out of date as the information says to go to where Microsoft Edge is noted as the Windows 10 system's choice of default browser, then to click on that and choose Firefox from the choice dialog box. Sadly Firefox is no longer in that choice dialog box. Please advise, thanks.

While trying to fix Firefox's massive memory leaks, I went to Help/Troubleshooting/Add-Ons and found these, which are NOT in the usual Manage Add-ons page:

Amazon.com extension Bing extension

ClearURLs extension <-- Oops! I actually installed this, to try to trim URLs of all the tracking crap when I paste one into a Facebook comment.

DuckDuckGo extension eBay extension Wikipedia (en) extension

All of the other extensions listed are ones I installed and wish to keep. EVERY time I install Firefox, I go to the One-Click Search Engines list and remove all but Google.

I don't know how these wormed their way in, but they don't seem to add any functionality for me.

I have my firefox crashed on every startup. Even in safe mode. Even when whole ~/.firefox folder is deleted.

If I start it with --safe-mode I can see

ExceptionHandler::GenerateDump cloned child 9079 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal...

If I'm trying to run beta version Im getting the same

I had most updated versions of Mozilla Firefox in my windows 10 machine. last two days, it is not opening. Tried several recommendations from Community page, Help documents and youtube solutions but nothing seems to be working.

• Tried re-installing firefox, by downloading the latest version from Mozilla, after deleting the profile folder (%APPDATA%)
• Tried removing the cache files / temp files etc., and restarted as well, still did not work.

I do not have admin permission hence could not open in windows safe mode.

Any suggestion please?, Appreciate your input!

I sometimes receive notification that Fx can't update automatically and I need to download the update. Twice now, the update has deleted my profile on drive D, and replacing it with a new one on the default C: drive. Settings, options, addons all GONE! I finally had to restore my entire system from a backup. What's going on and how can I prevent it happening again?

I just recently updated my Macbook Air to Big Sur and downloaded Firefox to use as my default browser. Installation went smoothly and I am able to use the program as intended. When I click on an external link, an window pops up and tells I do not have permission to open the app and to contact my computer or network administrator for support.

I am not computer savvy when it comes to programming and would love any help anyone has to offer.

Most appreciative.

Firefox stopped working on MacBook pro running OS 10.13.6. I deleted the app and tried to download a new one, the icon is crossed out and a prompt saying the app may be damaged or incomplete. Nothing had been changed on my system when this happened.
