Please continue here: [/questions/1398430]
When loading a page from a domain I haven't recently visited, it will almost always return the "Server Not Found - Hmm. We’re having trouble finding that site," error message. If I reload the page, however, it will load. Sometimes I have to reload 2-6 times before it works, but it always eventually succeeds. When it does work, it often times fails to load certain elements like fonts, images, embedded videos, and occasionally whole stylesheets--things that often require calls to third party domain. Again, reloading the page (sometimes multiple times) will cause the page to load properly.

I have already tried:

  • Different browsers on same computer (issue does not occur)
  • Firefox on different computers with different OS on same network (issue does not occur)
  • Cleared cache (issue persists)
  • Troubleshooting/safe mode (issue persists)
  • Deleted prefs file (issue persists)
  • Disabled DNS prefetching (issue persists)

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. I can exit full screen with Esc or F but the problem persists in full screen mode until I restart Firefox. Picture attached is my monitor when Firefox is in full screen mode.

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 getting a message on a yellow banner on various websites, most recently the New York Times, that reads:

A webpage is slowing down your browser. What would you like to do? Stop it, Wait.

An image is attached. If I select Stop It it sometimes goes away and sometimes comes back. It has recurred over several logins to the Times and it is very annoying as it impedes the fast loading of the webpage content and slows any activity. I would like to know how to permanently get rid of it.

My firefox worked fine this morning, but now it's not normal. The tabs are still there, but there aren't any website links written in the search bar and nothing shows on the screen. I even tried opening it in a different window or tabs, but all the browser except setting won't open. How can I fix this problem?

This screenshot explains my situation further (there aren't anything written in the search bar and the browser doesn't load)

About a week ago, Firefox suddenly stopped opening any download links I click on. When I click a link, the little dots in the Tab description slide back and forth and then just stop and nothing further happens.

I ran Firefox in Safe Mode and everything worked fine so I assumed it was an Add-On (I don't run any extensions). I restarted Firefox and disabled all extensions and then tried again...same problem, no downloads will start. I checked Hardware Acceleration and it's turned off and my Theme is set for basic.

As a further step, I uninstalled Firefox 32-bit and installed 64-bit. Unfortunately, the problem continues.

At this point I'm uncertain as to what else I can troubleshoot.

Any help would be appreciated! Thanks! :)

OK, apparently Firefox updated today- Feb 2, 2021 and it said to restart Firefox for the changes to take effect. I did that and Firefox loads, but it does nothing. When I hit "Home" it tries to work but it's apparently not accessing the internet. I can't access options either. I didn't uninstall because I don't want to lose any current settings, bookmarks, history, etc. I use Windows 10 on my laptop.

I did and automatic restart-- same result. I did a total shut down and restart-- same.

I checked with McAfee firewall and Firefox has access. No note comes up regarding any issue when I load Firefox.

I'm using Brave to write this, and there's no problem with internet access, obviously. 

So, which files or folders do I need to back-up so I can reinstall with bookmarks and history intact?

I tried 3 times to download a software upgrade from a German Vendor. The download failed several times so I contacted the vendor's support and they said try another browser. I downloaded the upgrade with MS Edge but I still strongly prefer Firefox for browsing. I could not find any answers that fit this issue in your help. I have no trouble with other downloads or previous downloads from Celemony. The zip file was about 70 meg, I think I've downloaded bigger files before. No big rush on this but I am curious as to what went wrong.

Unfortunately the crash reporter is unable to submit a report for this crash Details,the app did not ID itself" I can not get the browser to open in safe mode, I get the same error message(like the one above). Should I remove the browser and reinstall?

Somehow I managed to lose all of my windows, search history, addins, etc. It would appear that a new profile was created. I tried about:profiles and selecting the old profile (1.4GB) but while FIrefox starts, the places.sqlite file is now place.sqlite.corrupt. I followed the Mozilla instructions to try to fix the sqlite file but that did not help. I restored the full Firefox Application Support folder from Time Machine but that also starts with a fresh profile and selecting the old one gets me to a corrupt places.sqlite file. Given that I have TIme Machine backups, Is there no way to get back to a previous state with my windows, history, addins, etc. I am faced with losing a lot of work if I can't get back to where I was at least since a recent backup.

Thanks in advance for any assistance you can offer.

I recently switched to Linux from Windows on my older laptop, and have noticed that videos played in Firefox are very choppy with a poor framerate when in full-screen. (Audio is fine.) It becomes smooth again when I remove full-screen mode. I was using this same laptop previously with an older version of FF (on Windows) and had no problems.

I tried other browsers and the stutter/choppiness is not present. Any suggestions on how to fix this? Firefox safe-mode did not solve the problem.

OS: Linux - Zorin OS 15.3 Lite Firefox: 85.0.1 (32-bit)

Thanks, Dave
