Putting people before profits since 1998 ___________________________________________________ Wierd. Thanks. Greg

I receive this Error msg trying to access Settings option in the AJC epaper section https://editions.ajc.com/shortcode/AJC412/edition/f117d96a-c78b-4df3-4b6a-0e587f6cfd22 on a Firefox Browser:

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

Since the last update, Gmail has not been working correctly on Firefox. All of the buttons to the left of inbox emails that enable you to move, categorize, file, etc your emails have disappeared. I have tested my Gmail account on Chrome, Edge and DuckDuckGo browsers, and everything displays correctly. Please help. An image of the missing buttons is attached (well, since there aren't there, you're seeing a blank area of gray to the immediate left of my inbox [or any other folder] emails). Many thanks -- this is driving me crazy. P Haynes

normally i just click the forefox icon on my taskbar and type claude.ai in the address field but today i was messaged that the claude program needed a mozila account - so I had to set one up. why and still cannot get to Claude

I use Arcgis quite a bit for property info and for the last several months, it either won't fully load or has constant freezes when doing anything. It also freezes other windows I have open and most the time when I shut down those windows and start FireFox again, my home screen (Start Page) won't load? I have to dump history/cookies and sometimes flush dns. I contacted ArcGis and they say it works fine on their end. So I suspect FireFox is the issue.

I downloaded the Opera browser last night and it has no problems with this site. I won't use chrome or edge.

Any help figuring out what's going on? I have changed no settings, no vpn, no private browsing either. It seems with each FireFox update, my issues get worse?

Win 10 on desktop. FF version 145.0.1 the site in question https://experience.arcgis.com/experience/ba70b3d86f5e4bbeb7582591f3dde16a/

I am not able to access my emails in Yahoo Mail. Can't even send emails. Tried accessing Yahoo Mail using Chrome and did not encounter any accessibility problems.

When I go to YouTube to watch videos the Vid's always stop after a short time. The refresh page and back buttons do not work and neither does the ability to click on any links on the page. I have to close the tab and start again. The issues still occur on new tabs. Eventually I have to close FireFox altogether but when I try to open FireFox again it does not work or takes a few minutes and sometimes the message Firefox is still running. At times I have had the sound of the videos, when they do play, from YouTube still playing even when the browser is closed.

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

Last night my machine updated itself but now I cannot access Facebook as it says I am using a browser version not supported by FB. I checked and my Firefox browser is indeed up to date. Have I been hacked or what?! Thanks. Geoff

Online purchases only work on about 50% of the websites I buy on. The most recent one was buying a gift card from Whole Foods. This is becoming so ANNOYING; before I finally switch to another browser, does anyone know how to fix this?

i can't get youtube to load on firefox i have updated it all it loads up on competitors chrome,Etc can anyone help I've changed the password twice i get a black screen and 3 lines on the left unclickable and three circles also blank and unclickable i have windows 11

After going into Home Depot Canada's website, I can't entre into their departments sections, just see nothing. Maybe somethins wrong with my Firefox's settings? Please help. Thanks.
