On ubuntu 20.04, the snap version of firefox can't play some videos. Some youtube videos will play but streams won't, and then I get the message "to play video, you need to install the required video codecs". On telegram web and tweetdeck I also get this message while trying to play some video.

Since it's a snap, nothing I do on my system will solve the problem, I cannot install any codecs.

It's firefox 89.0

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

Recently I have noticed that where there are drop down lists on websites I visit the drop down function no longer works properly if I am using the Firefox browser. If I click on the arrow in a drop down list box the list briefly appears then disappears almost immediately making impossible to select an option from that list. I don't have this problem if I use any other browser like Safari and the drop down list function used to work on Firefox, so presumably this is a bug unless there is something in preferences that needs changing. I am using v88.0.1 on mac OS Sierra 10.12.6. Any help wud be appreciated

I've been having this problem recently (firefox build 82.0.3 and a few older versions) where characters randomly disappear from the text being displayed. In addition to webpage body text, the address bar and tab titles also disappear sometimes.

As I'm typing this text characters are randomly being replaced with blank spaces. Firefox is the only application on my computer that seems to have this problem. I have restarted it, reset the user profile, and disable all extensions/add-ons in an attempt to debug but it hasn't seemed to help.

Attached are two screen captures, one where the text has disappeared on me and one after I highlighted the text to bring it back. Note: the address bar and tab titles are blank in both since I didn't highlight/click on them.

So I've noticed how some video files are able to be played back in Firefox. Some are not able to what so ever, for example I've created a text video using this FFPMEG command: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mp4

which created the following file: https://astolfo.nl/i/z2ada.mp4 Both the uploaded version and the local .mp4 are unable to be played back in Firefox. However opening them up in edge chromium both files play back perfectly. Besides Edge I've also confirmed it plays back nicely in MPV.

I've tried Hardware acceleration, but both having it on and off did not change the fact that these files wouldn't want to playback in Firefox. Safe mode also did not effect this issue.

Hi @ all,

our website https://ana-dismissed.de/ is not loading in Firefox, or to be more precise it is loading often but on occasionally not reloading when refreshed. This only happens in Firefox, Safari and other Chrome-based Browsers don't show this, perfectly working there (as far as I could check).

I already checked Firefox developer tools, like console or resource loadings etc. There is no issue I can find. I'm completely lost, no hint at all, why this happens in Firefox only.

Please find a short video here: https://imgur.com/a/31XyiMi

I'm thankful for every hint into the right direction.

Best regards!

Hi, I'm using Firefox 85.0.2(64-bit) Windows 10

While I'm testing local testing for website, whenever I typed/entered localhost OR localhost:8000 Firefox keep redirecting/guesing subdomain for it(which="www"). Made my testing messed up.

There's same issue on https://support.mozilla.org/en-US/questions/1216065 None of those work.

set: browser.fixup.alternate.enabled to false or Connection Settings with No proxy

Please, stop. Chrome and Edge behave normally. This site need darkmode :/

Hi all

For a while now I've had a problem in Firefox where images randomly show up with green blocky glitches or yellow lines on them. Also sometimes text does not show correctly. I've attached a couple of examples. The image is from my Facebook feed (but it can happen on any website it seems) and the text is open tabs - the one on the right is this page.

Any suggestions? I've refreshed the Firefox install, and have only one add-on - an ad blocker. I've tried two different ad-blocking add-ons and the problem persists with both.

Thanks

I have a website that uses live data from an MQTT server. The server has proper certs, and works fine with Chrome, Opera, Edge on various platforms (mobile, Windows, Linux). The live data does not display in Firefox and has not in several months/FF builds.

The console shows The connection to wss://weather.ghammer.net:9001/mqtt was interrupted while the page was loading.

No further info is available. In order to continue to use and recommend Firefox, this needs to work as in other browsers.

Any ideas?

Yesterday I was using Firefox normally (browsing, Discord, etc.). Today when I opened it, it wouldn't load any page. If I type something in the adress bar it will auto-complete or show suggestions based on google, but when I hit enter, nothing happens. It doesn't even try to load anything. I also can't go into options. When I click on the options button, nothing happens. I am not running in any compatibility modes. I have tried reinstalling Firefox, didn't help. I am not using any add-ons. I have done several virus searches. Other browsers work fine. I'm running out of ideas now, that's why I'm doing this post.

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox
      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

Thanks, Mahesh

A couple of weeks ago I started seeing a screen apparently belonging to Cloudflare when i tried to log in to my Constant Contact account. It just slowed sign in but had no apparent effect and I assumed it was something on their end. Then just a day or so ago it caused me to be unable to access my account returning a message that my credentials were incorrect on the login page. I call Constant Contact support and They have no idea what I am speaking about and suggested a private window. That worked for a while but seems to have failed and I had to go to another browser most recently.

I don't see Cloudflare in my installed apps in Windows 10 and it is not an extension in Firefox that I can find which all the other web search have pointed to. Where did this come from and more importantly ow do I get rid of it?
