How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

If I use my touch monitor when a video player is full screen, the full screen Firefox window turns grey and becomes unresponsive to mouse and touch input.

Hi. I am trying to reach a site that I have in the past found a good reference site (if you like reptiles), Ian's Vivarium. I am in up-to-date Firefox for Win10, I have refreshed Firefox to no effect. Error message on the website is: "You are running an unsupported PHP version. Please upgrade to PHP 7.1.3 or higher before trying to install or update to phpBB 3.3" at the top of a wholly blank page.

I get the same error when attempting Chrome and Edge (which crawled back onto my PC uninvited)... maybe a website issue?

Help?

While not totally computer illiterate, I'm pretty close....

Thanks in advance?

i am unable to download full web pages such as login pages to web sites. for example, I can download the home screen for online banking but the screen comes up completely blank or missing the usename/password boxes. This condition occured without any changes on my part. The same websites still operate normally on other computers at home. Most website downloads just end up with a blank page and the mouse pointer circling around forever. This is a relatively new PC with no other issues till now.

Hello! I need help on a very strange problem I had recently with my Firefox. I have Firefox 83.0 64-bit installed on my Windows 7 Home Basic desktop PC. Some time after maybe version 81 and above, I noticed that my Firefox randomly closes and reopens without showing any error messages. I noticed that the most consistent time this phenomenon happens is when I turn on my PC and start Firefox, it almost always closes and reopens, sometimes even more than once. It acts like the browser crashed, but the weird thing is it doesn't show any error message saying that the browser crashed. Once I opened Firefox at least once after I turn on my PC, even if I manually closed it and reopen it later, it will not crash on Firefox startup, it will probably only crash again after I restarted my PC and open Firefox. Also rarely, Firefox randomly closes and reopens whenever I browser whatever website with no reason whatsoever, but this only happens 3 out of 10 times.

I opened Troubleshooting Information to look for clues on what might be causing this, and I noticed "Launcher Process" is "Disabled due to failure". I am not sure what that means though, but I have a feeling this might be related somehow?

If anyone has any idea on what's going on, please help me. Thanks!

I am using Windows 10 and up until last week have never had any problem with Firefox. Now when I log into my Telstra account, I can see all the services available except Telstra Webmail. When I select Webmail I just receive 3 flashing square dots but the page will not load. I am able the access my Telstra Webmail from Internet Explorer but not Firefox. Telstra has suggested that I use Google Chrome instead of Firefox but I would prefer to use Firefox so hopefully someone can help me with this issue.

Using Firefox 85.0b2 (64 bit) Windows 10. Both Firefox and Windows 10 updated themselves in past couple of days.

Previously Firefox played videos on YouTube. Now it does not. (still image appears, and spinning circle but nothing further; and then YouTube suggests try restarting my device).

Videos still play OK in MS Edge.

I have tried all advice I can find, including clearing Cache, clearing cookies, and resetting Firefox. Starting Firefox in Safe mode. Restarting Windows and Firefox multiple times. Nothing has made any difference.

Can anyone suggest anything else to try??

I am having troubles using the web site "The Daily Wire" on this laptop running Windows 10. The site will either not open at all, or if it opens, the articles on the site won't open when clicked on. I have uninstalled and refreshed Firefox, same problem. The site works fine on my desktop PC when using Firefox, and on this laptop when running all other browsers. Any ideas?

My Firefox 84 is now in an endless loop with updates.

It asked me to download an update from version 84.0.1.

After Firefox closes, installs updates, and restarts, it comes back asking me to update again.

The cycle continues and the updates never complete.

In the Help...About box, the button is still there "Restart to Update Firefox".

I'm using 32-bit Windows 7.

Images attached.

Please advise.

Thanks!
