Firefox Support Forum

A website I use frequently has recently been causing error; "Application error: a client-side exception has occurred (see the browser console for more information)." to show up when I visit some of their pages but not all.

Example: https://www.guitarcenter.com/Used/Ibanez/RG5121-Prestige-Solid-Body-Electric-Guitar.gc

The page begins to load and then presents this error. Any help would be appreciated.

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

There are always PR_END_OF_FILE_ERROR type error given by Firefox when opening secure https:// official web sites of government of India, which end in gov.in Why not firefox browser allow opening such websites which are authenticated government web sites ?

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

Firefox updated to 97.0 (64-bit) this morning for me and immediately ceased functioning. It could not even load about:addons or about:settings. Other browsers worked fine, and by processes of elimination I found it to be Webroot that was causing the dysfunction. I've already opened a support ticket with Webroot, but I wanted to make Mozilla aware of this conflict and to ask if there is anything that I can do to remedy this besides completely disabling my anti-virus/spyware to use Firefox?

Hi guys,

I don't know when and how exactly this thing was added to my firefox behind my back, I don't like it, I don't like Baidu Pan either but I have to use it.

I checked the extensions and add-ons, nothing suspicious was found.

Can you please help me remove it?

Firefox won't open my professor website: https://danielesirangelo.altervista.org/ and there's this error How can i fix this?

I have been a "light theme" user for 15+ years. Since updating to 96.0 today, a dark mode spreading across Firefox has been forced onto me, including:

• New tab background
• Background of any tab waiting to load a page
• Google/Youtube background
• Settings/add-ons/password menu backgrounds
• Automatic username/password drop-down background
• Background of the little box that appears on the bottom-left (the one which shows the URL when you mouse over a link)

I am unhappy with this and wish to have my usual theme back. Can anyone please assist?

(In addition, there is some sort of white border around the current tab, which I do not like)

So I was cleaning out my SSD of a bunch of junk files and I think I might have deleted a file Firefox needs as when I open Firefox it seems to just blank with the search bar and when I try to go to say YouTube nothing loads. So I tried to do a fresh redownload of Firefox and the installer just this error saying "The code execution cannot proceed because vcruntime140_1.dll was not found" can someone help me get Firefox working properly again?

Hi, I've tried enabling Java Script but I must have chosen one of Firefox's browser extensions that is blocking it. I just don't know which one. How do I see those and make changes?

Thanks

Several days ago (approximately 12-3-20) my Internet Download Manager add-on stopped working. Removing it and reinstalling it by using a link provided by IDM does not work. It will work only if I open the webpage where I intend to download (e.g.--YouTube) BEFORE I reinstall the add-on and only for as long as that page remains open. Closing the page and then reopening it somehow deactivates IDM, as it will no longer link to the video I want to download. Have tried everything i can think of to solve this, including deactivating all other add-ons and by uninstalling and reinstalling the IDM program itself. I also unchecked the "block popup windows" management tool within Firefox itself. Anyone have any ideas what is happening? Initially, I also received the error message added below, but as far as i can tell, none of my other programs are set to block IDM. The error message no longer appears.

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!
