I created an e-learning course and published it to web. On several slides in this course in Firefox browser (91.0.2 v.) some pictures disappear and appear randomly after some time (for example 30s). These errors do not occur in Chromium based browsers - like Microsoft Edge. These images disappear/appear when the window of Firefox is rescaling too. The problem has been reported to authoring tool support and has been confirmed by them. Any suggestions from Firefox browser users?

When using Firefox and searching with Google.com I will experience an issue where the Google links/websites won’t load. And if they have previously loaded and the issue begins none of the elements work. This issue is frustratingly intermittent. It will be fine for a few min and then break for a few min. I'd attach screenshots but there is no error - simply does nothing. I have done a bunch of troubleshooting and testing to get to the root of the issue.

  • Reload page
  • Restart Firefox
  • Cleared cache
  • Disabled Privacy/Security settings
  • Disabled Plugins
  • Updated Firefox
  • New Private Window
  • Tested another browser - Other browsers load google sites
  • Tested non google websites – Other websites are loading
  • Tested another network

I’ve noted that google.co.za seems to have a separate intermittency from google.com. However, I have tested and found both can be ‘broken’ at the same time. It also happens with Youtube.com. I am quite happy to continue troubleshooting, I just need some direction.

Since recently Firefox keeps losing my session/tabs. This happened thrice in the last days. Yesterday, I even refreshed Firefox (about:support > Refresh Firefox...) but today all my tabs were gone. In addition, upon closing Firefox asks if I really wan't to close it and the open tabs although "Restore previous session" is enabled.

about:crashes shows no crash reports.

OS: Ubuntu 21.04 64-bit Firefox: 91.0.2/20210823123856 Add-ons: Sidebery, uBlock Origin, Privacy Badger On a different computer with Windows 10 (and same add-ons) the problem doesn't appear.

I prefer Firefox but speed-tests show it is considerably slower than Chrome and Edge. I have cable network connection. Max download speed is 1000 Mbps. Test show above 900 Mbps for Edge and Chrome and 5-600 Mbps for Firefox, sometimes it is much slower and sometimes download stops for 5-20 seconds. I therefore tried "Refresh Firefox" - and my dear Bookmark sidebar disappeared!! Firefox info told me bookmarks would be saved. Well, it is saved, but it is real troublesome to use it compared to my old sidebar. I WANT MY OLD SIDEBAR BACK - ANY HELP? Kind regards Toralf

Clearly my 3 PCs are somehow connected, since they all show up in "connected services". But though the one I am now typing on routinely reports that it has successfully synced, it hasn't in fact connected to the 2 other PC's Firefoxes for the past 2 years (according to the image uploaded below). I somewhat doubt that actually, but the fact is that the 2 other PCs have identical bookmarks sets and are clearly syncing, but this one has a different bookmark set.

How to force it to connect? Disconnect it and reconnect it? Delete Firefox and reinstall?

I have had this issue for a long time so in multiple versions of firefox where images of different types don't load correctly and are replaced with a garbled tv-test image type.

On the attached image you can see an example where dots on the map wont show correctly. Can this be some sort of privacy setting I have enabled withot knowing? I have reset firefox but still get the issue.

For a couple of days i have a problem with the playback of videos in Firefox.

The Video freezen for a couple seconds (3s - 5s mostly), but the audio continues without any problem.

This problem accours predominantly on Youtube videos and livestreams. But i noticed it on Twitch as well, although the freeze duration was shorter.

I could not notice this issue when using other browsers.

I tried: - turning of hardware acceleration - disableing addons - different video qualitys (480p - 4k) to no improvement.

When I type a search query into the address bar and pres enter nothing happens, the little dot symbol just goes back and forth. Tried changing search engine, no change. MS Edge works OK.

I have just moved to Spain, could this be an issue, it never has in the past. Also Firefox updated to 91.0.2 just before I left UK.
