Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

"Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor."

Why am I being alerted when I sign in to Firefox to finish setting up my account? I think that I have had an account and already sync my devices for the last decade, but less than a century. When I follow the sync instructions i get put on a loop of needed to "pair from within the Firefox app," on my phone - which I was using when instructed to "open Firefox" very confusing as to what I am doing wrong.

For some time now I haven't been able to access certain websites like Facebook or Famileo, even though they work on another PC. Firefox runs constantly What should I do?

The links in every browser are going to take you (redirect) to a half-dozen places you might not even know you're being dragged to, in order to follow a given link: Think a 'news' item, that is or isn't. 99 times out of 99 you will visit advertising, also a paywall, or whatever they call it this week.

All of this is a waste of my time, which why I think about clicking on anything, knowing that it'll likely NOT be what everyone else wants you to think it is. For those times that I have my brain on remote, I want a list that I've made myself that'll take my blind clicking out of the loop before the nonsense even starts.

My own personal White List.

Firefox browser when on Foxnews will crash and causes PC to completely reboot? This has been happening on multiple PC's in my house and has been happening for months.

For the last few days, Firefox is being removed from my computer overnight and i have to re-intall the browser the next morning. Sometimes it's still there the next day, and sometimes it's gone again the next day. What i causing this and how can i prevent it from being removed? Jenny

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

I have tried over several days to uninstall and reinstall Firefox to avoid tabs constantly crashing. While I've done this and multiple shut downs and restarts it continues to crash and can't figure out why. Please help.

When I brought Firefox up about a week ago, it presented me with a survey, results of which were sent to Firefox developers. They asked several multiple choice questions about features, but they didn't ask a very important question: Would you use Firefox more if it used less system memory? I currently use Google Chrome for about 2/3 of my web browsing because Firefox uses up too much system memory. I would prefer to use Firefox most of the time, but can't, since it bogs down when memory usage gets too high.

The survey should have included a text input box so users could enter any comments for the developers, and the survey did NOT do that.

So, after completing the survey, I was disappointed that I couldn't comment on the most important issue I have with Firefox. I would like the Firefox dev team to try get Firefox's use of system memory down. A short while ago, I opened 4 websites in Google Chrome, then opened the exact same 4 websites in Firefox. The attached shows the memory usage of each browser.
