Setup: macOS Tahoe (26.4) and Firefox 149.0

=

Behavior: Out of the blue this morning, every website I try to visit in Firefox returns "Looks like there’s a problem with this site". Every other browser works fine.

Things I've tried, that haven't fixed it: - Ruled Out DNS: Sites like 1.1.1.1 and my home router's IP return the same issue in Firefox, but also resolve in any other browser. - Firefox Safe Mode: no fix - Deleted All Settings, Reinstalled Fresh: - Removed the Firefox App, deleted:

       - ~/Library/Application\ Support/Firefox
       - ~/Library/Caches/Mozilla
       - ~/Library/Caches/Firefox

...and then downloaded and installed 149.0 fresh. - Refreshed Firefox (via [link] - about:preferences (toggled between FALSE and TRUE, testing each time) via this YouTube video

- network.dns.disableIPv6

- network.dns.disablePrefetch
- network.dns.disablePrefetchFromHTTPS
- network.dns.disable

....and in desperation, I checked my Mac for Malware (clean)

I'm at a complete loss: every other browser works, but Firefox is a 100% fail for all websites. Any thoughts?

Hello, I am currently using windows 11 with firefox 149.0. Regardless of what website I use (youtube. steam etc), the browser struggles to establish consistent connection to my bluetooth earbuds. It connects for one moment, but then soon the volume goes out and eventually it disconnects. Though it would reconnect soon, the cycle just keeps ongoing. I have experimented with other apps and browsers, as well as multiple bluetooth earbuds of other brands to be sure that it is a firefox issue. I have checked the volume mixer menu to ensure that there is nothing wrong. I have also made sure that my drivers are all up to date with no issue. But the issue still persists.

First, I am technologically illiterate, so my terminology will be imperfect. Until today, there was a second line in my Google browser that listed my favorite sites I visited daily. It was just below the Google Tab line (the very top line). That line is now gone and now I have to look up the web addresses in my bookmark thing off to the right. How can I get that favorite sites line thingy back?

Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

Hi, ok, so my computer just randomly updated my Firefox Browser and now all of my bookmarks, saved passwords, extensions, themes, and history is gone. I used the links on the support website, but they were not helpful at all. I am logged in with the same account I was originally logged in with prior to update 149.0 (logged in with gmail). When I sync data in settings, it automatically imports my Safari and Chrome information (which is not what I want). I try to import my bookmark and password history from the saved HTML and CSV files under Mozilla Firefox, but I don't have the ability to do so, as the files are essentially 'greyed' out. I have tried every step to troubleshoot and every link that is related to my issue listed on Mozilla's support with no success. I have even searched my issue on Google and Reddit. Please help!!

I recently installed an rtx 3060 12gb on my old system (Win10, ga-h77-ds3h gen3 mobo + xeon ivy bridge cpu). I installed latest Nvidea Studio drivers. Everything seems fine apart from Firefox, which showed visible artifacts/flickering lines on the screen. I disabled hw acceleration in Firefox settings and now instead of the lines I just see micro dots which change position frequently. As recommended by AI i changed some other settings in about:config but the tiny dots are still there. Starting Firefox in safe mode they are still there. On MS Edge its fine, there are no dots/artifacts.

Is there something else that might fix this or there is nothing that can be done, its just how the rendering engine works on older systems and rtx 30s cards?

Currently the built-in VPN operates via a blacklist system. Where it is turned on browser wide, with exception of sites you manually add to the blacklist where it will turn itself off when on those sites.

To preserve the allotted 50gb data limit for using the VPN, I would ideally need to turn the vpn off of every website that I don't need it to be on which is extremely tedious even if it's a one-time annoyance.

It would be better if instead(or in addition to) we had a whitelist option where we could have the VPN not be active browser wide, with exception of any site we add to the whitelist. I would much prefer this because there's only a handful of sites that I would need the VPN to be on.

Firefox has been my browser of choice for well over 20 years. I have a game I play every day (from FaceBook) just this week when I try to go to it on my laptop - it says your browser does not support WebGL. it has always opened using Firefox - this is a new error message. and the computer is only 5 months old and has Windows 11 on it. I do not want to switch to Google or Edge.

Like I said - opening the app worked every day up until about a week ago. What gives?
