Whenever I click on the Firefox icon to start, instead of FF, AOL comes up. I looked on my C: program list and it is not listed so I can't delete it. It just started doing this in the last week. I tried downloading FF again with no luck. Its on an old windows 10 machine.

When i try to connect to some websites, firefàx prompts "error 502 bad gateway" the same websites work on EDge !

Unable to connect

Firefox can't establish a connection to the server atxxxxxxxxx

Error code: 502 Bad Gateway

Try Again

I'm exploring Steam Deck desktop mode more and I'm running into issues with Firefox not rendering some videos on my personal website. I wasn't sure if it was a Steam Deck, KDE Plasma, Firefox, or an issue with something else, so I tested the same website with Vivaldi and the video played without any issues. This makes me feel like it's probably Firefox, but not totally sure yet.

I've already tried adjusting the autoplay media permissions for the website from the default to "Allow Audio and Video" in case that was doing something. I've also tested in Troubleshoot mode to see if the one extension I have installed was causing any issues and that didn't change anything either. Any other ideas I can try? Or, is there some way to determine if this needs a bug fix/there's nothing I can do on my end?

when i booted up my laptop this morning i notice all of my tab groups were gone. i know how to get to where the tab groups are held, but when i click on the down arrow thing none of my saved tab groups appear. is there any way i can get them back? i used them for art references so theyre pretty important to me

I always have multiple tabs open in my browser. Previously, I could easily open (and switch between) 20+ tabs (I have 16GB of RAM). Recently, after opening five tabs, the Task Manager shows 10-11GB of RAM (88-90%) in use! How can this be? I cleared the cache and history, but it didn't help. I installed several RAM cleaners, but none freed up the required amount. None of the five programs worked. Where does that 15GB of RAM go when I open Firefox? When will you finally implement something like Google Chrome—they free up RAM for active pages when inactive ones are opened. Maybe it's because I have so many inactive tabs that the RAM is disappearing? But I had just as many tabs before, some of them inactive, and fewer than 20 active ones, so I could easily open another 20. And now I can't even open five new ones. What's happening to the browser?! SOS!

I have a question about deleting a Firefox profile. When I access the profile screen via "about:profiles," I see two profiles: "default-release" and "Default User." The "default-release" profile is fine because it displays the message "This is the active profile and cannot be deleted." But is it okay to delete the "Default User" profile? Should I also delete the files in the root directory of the C: drive and the local directory? If I delete the "Default User", will it be deleted as well?

since many weeks, a lot of website don't work any more, sometimes it work in private, sometimes not at all. i have to use chrome, i hate it but after 20years of use of mozilla, i'm ready to change because of this problem, i don't want to waste my time to use 2 navigators, or try 2 every day.

The task name is:

• "Firefox Default Browser Agent 308046B0AF4A39CB"

It runs at 10:07 every day. The command line from task scheduler is:

• C:\Program Files\Mozilla Firefox\default-browser-agent.exe

Command Line Arguments:

• do-task "308046B0AF4A39CB"

It reports that the version of the browser is wrong and that my profile was used with a later version of Firefox. But everything works just fine so how do I fix this error?

How can I control the intensity of dark mode, if its possible? If, not what?

Some website uses different colored font that is absolutely invisible on a dark mode page.

Firefox 147.0.4 (aarch64) "hangs" for 30 seconds to 1 minute when I launch it on my MacBookPro (OS Tahoe.26.3). Itwon't open the simple web page I have Firefox set to open when it launches -- and I can't navigate to any other web pages. When I try to interrupt, I get an Apple spinning beach ball until finally, Firefox opens that first page.

After working with Apple tech support, I have disabled a number of content barrier Extensions in Firefox-- which Apple tech support felt might have been causing this behavior. Nothing works. And I hesitate to run Firefox without some of them.

I tried deleting my Firefox user profile from my computer, but all that did was prevent Firefox from opening at all.

How can I stop this?
