Firefox Community Forum

I am writing this in Chrome on my old Win 7 HP laptop. There are no problems there. Microsoft should have just ended with Win 7, their only working OS. This is a big old laptop, heavy with a 17" screen, fragile, nonworking touchpad and with dying battery. For traveling I actually use a newer laptop - Dell XPS 13, light, sturdy, bright screen, long life battery, tiny... That came with Windows 10 initially and upgraded to Windows 11 later. I used Chrome for browsing initially just like on this laptop. At some point (I don't know whether this happened after Win 11 upgrade, I just didn't pay close intention to what Windows are doing behind my back) I just could not log on to Facebook in Chrome on Dell. Nobody is out there to help. Neither at FB, nor at Google, neither at Microsoft. Everything else worked fine. Before my travel to Europe this summer, I uninstalled Chrome and installed Firefox instead on the Dell. I carried over all my Google passwords. And everything worked fine, including Facebook. The trip to Europe went fine. Firefox performed great. Now a week back in the States, suddenly yesterday morning, out of the blue, without me doing anything to cause that (the day before I shut the lid, and everything worked fine), all hell breaks lose: I can't open a single page in Firefox - yet my WiFi connection is fine, and other devices work fine. Firefox opens the home page but nothing else, when I click on troubleshoot, my WiFi connection is suddenly dropped and I have to reconnect. I don't have Chrome on Dell, but I do have Edge, so I checked Edge: Edge opens some pages immediately, some pages only after I ask it repeatedly, all much slower and more laborious then it should be. So, while it did not lose functionality altogether like Firefox, I would say it is also not operating properly. But Skype, email software, printer connection - they work fine. Some satanic force entered the computer overnight and destroyed browser functionality. And I reseted everything and rebooted and restarted and deleted cookies, all the usual crap they tell us to hide what is really going on (some screw up or intentional sabotage in the code). There are no proxies. Firewall on or off does not matter. List of Windows updated shows the last one on 8/14, and for 10 days there was no problems. I fiddled with command prompt: sfc/scannow says everything is ok, malwarebytes say computer is clean, Edge improved after netsh winsock reset, but Firefox did not, I sent a request for tech support to Dell, but this can't be a hardware issue, it is most probably some software security bullshit issue that happened behind my back and that now requires someone with PhD in programming to figure out and solve. I am totally exhausted and very unhappy with the situation.

Couple a days ago jetblue.com website stopped working. When I login to it, yhr whole website is greyed out and doesn't respond to anuthing. Elvart

Letmewatchthis Watch Letmewatchthis Watch and but other sites are fine letmewatchthis.city. Regular visitor to that site and tests show it is up

Just suddenly 3 hours ago, Letmewatchthis.watch stopped working for me "Unable to connect

        Firefox can't establish a connection to the server at www.letmewatchthis.ch.
      

The site could be temporarily unavailable or too busy. Try again in a few
  moments.
If you are unable to load any pages, check your computer's network
  connection.
If your computer or network is protected by a firewall or proxy, make sure
  that Firefox is permitted to access the Web."

I am running Firefox 129.0.2 (64-bit) on Ubuntu 20.04.4

Recently, I have been browsing a StackExchange site and hit the back button of the browser several times (still remaining on StackExchange). I then realized that upon the last button click, Firefox downloaded a weird HTML file called something like ha71ksd.htm. The file was empty (0KB) and when uploading it to VirusTotal it showed me a completely different file there (probably since the hash of an empty file is always the same).

In any case, I am a bit worried that I might have been infected by a virus. Therefore, I'd like to at least reproduce what happened. I read in different places that it might have something to do with a wrong MIME type reported by a server prompting Firefox to download instead of displaying a file. But Stackoverflow having such a misconfiguration is also strange. I know that a 0KB file cannot contain anything malicious but the whole incident seemed highly suspicious and I need to find out what happened.

Any help or tips are appreciated!

I am facing an issue where i sometimes search but it doesn't load. Its as if the links breaks. Refreshing doesn't work. I open a new tab and sometimes it works or i spam my search then it loads.

Its getting to the point where i face this issue i open Chrome to do my search. Which is inconvenient I started facing this after i updated. Please may I get assistance.

I joined a couple facebook groups. Each offered a file tab with documents available for download.

I tried numerous times with firefox and it failed. Clicking the "Download" item on the ... menu caused the same files tab view and list to open in a new tab.

I hated to do it, but I dusted off M$ Internet Explorer, logged into FB and joined a group, clicked the Files tab, selected a file, clicked the 3 dots, menu popped up and I clicked "Download". Poof. The Save As popup appeared, the file was downloaded. Works as expected with IE.

Might there be a setting in FF that is blocking such downloads of PDF and .doc document files?
