I was in the middle of a bunch of work and this Avira pop up showed up blocking 1/3 of the screen. Probably a scam, but no way to get rid of it. Finally I had to reboot. I googled options and none of them worked. I have been getting Avira "scare tactics" but they were easy to close. But this was extremely annoying. If this continues, how to I get rid of it??

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

I'm trying to switch from Chrome to Firefox after getting pissed off that Chrome removed Unblock Origin. I'm using Ubuntu 24.04.

My Yubikey worked on the snap version of Firefox but I got rid of the snap version because it was consuming 40% CPU to use Google Meet. The apt version uses less CPU, but now my U2F keys don't work. Any website that says "Touch security key", touching the security key does nothing. No feedback whatseover.

What gives?

This is a horrible UX. Installing a browser and having it work optimally out of the box should be a one click thing.

Hi,

I have added the google maps and google.com as exceptions in the security tabs. Works in Chrome. Re started , cleared cache etc. On mac opened location to share so all green lights just can't add directions to google calendar in Firefox only...used to work.

Thanks

Yesterday 04-24-25 I had one tab open, I opened another tab to go to a differant website and the Bookmarks file folder was empty. I went back to the original tab and only one file still had bookmarks in it and when I tried to add others or export the manage bookmarks only showed about 10 to 15 bookmarks still in ALL of Firefox. There had been at least 100. When I try to add bookmarks or modify the few left It goes though the steps but makes no changed or additions to the few files that are left. So the bookmarks option has toally stopped working.

I ran both Norton and BitDefender(downloaded to see if Norton missed a Virus) Neither came back with a Virus. 
 WTF guys?

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

I was watching YouTube as usual when all of a sudden Firefox randomly opens a page 'moz-extension://98ca81c4-74e4-49b5-baf3-377df6aa10a0/content2/privacy.html.'

It belonged to my extension Video Download Helper, and I thought it was strange because when extensions updated, it never did things like this. Could someone help me figure out what it was perhaps? I want to make sure I'm safe and there hasn't been any data breaches or any hackings. Thank you.

Hi Everyone,

I'm using the latest version of firefox 137.02 (64bit) I think it updated when the other day "checked for updates"

I was calling up someone on facebook messenger (app) only last Sunday and everyone was fine today the same deal I get this message as attached.

All the camera privacy options are on to "allow" and still it won't fire up.

When I open up Google Chrome it works fine.

Any Ideas on this please?

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

Now that Mozilla/Firefox have joined Google on the dark side, who is everyone switching to? I would like something that works well in both Windows and android. I hear Opera can't be trusted and I don't like how there are like 6 difference versions of Opera in the android app store. DuckduckGo is just badly made IMO. Edge causes some glitches with one of the sites I use most. Should I try Brave? I just want a browser to BROWSE the web. I don't want AI. I don't need a VPN or adblock built in. I don't want a "gamer" browser. A decent local password manager would be nice but I don't want to have to make an account to use it. I know if the product is free, you are the product, so I would almost prefer a browser you pay for but oddly that doesn't seem to be a popular option. Probably because the user data the companies collect makes them more money then people would be willing to pay. Sad times. I miss the 90's.
