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.

My hide tab bar with one tab code has broken with 76. The tabs themselves remain collapsed, but the bar remains. Here's my userChrome file:

Hi

I recently updated to 78.10.0 vers and now when I try to play Netflix I get the WidevineCdm crash message and Netflix won't play

I have refreshed Firefox and restarted my Mac several times and disabled the Adobe Shockwave player.

Nothing works.

Can you please help me?

Hi everyone,

it's been 2 days now since every time I open Netflix and Amazon Prime videos won't play. A yellow bar saying: "The WidevineCdm plugin has crashed" keeps coming up!

I'm using Firefox and I'm on a MacbookPro.

I've tried everything: restarting/shutting down device; reinstalling Firefox; deleting widevine folder and activate it from the adds on page; tried on other browsers (works on safari but not on chrome); contacted Apple / Netflix / Amazon / Google nobody was able to help; I also ran these websites with my Mac in safe mode...nothing was able to resolve it.

What can I do to fix it please?

This started to happen out of the blue...I haven't installed anything! It was working fine until the day before...

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

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 ?

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?

Please tell me how to change home in Firefox I have changed my computer settings - home into https://www.baidu.com/, but not work. I am not happy and upset. I cannot control my computer and my browser home Please tell me why I cannot change browser home, and how can change it.

Many thanks xuan liu from china 2020-7-17

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)

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?

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
