Help -> About "Failed to check for updates."

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

New computer, new Firefox install. Old computer has the Library Icon in the upper right corner when the browser opens. I imported my bookmarks, but can't figure out how to get the Library Icon positioned.

Hi and thanks for your help. I was playing around with my DMARC settings for my new site and was looking around at who was hosting my WordPress domain for http://ibizignite.com, and Google directed me to GoDaddy. That was wrong. However, in my fooling around, somehow GoDaddy and this associate Westechnologies keeps popping up when I open up my browser after booting up my computer, and I cannot get rid of it. I don't know where to find it, because there is no associated extension anywhere in my extension list.

Here is the address that came up: moz-extension://dfdaa01e-fa7e-4241-8590-a19edb2ec40f/data/blocked/index.html?url=https://www.godaddy.com/forsale/www.westechnologies.com?utm_source=TDFS_BINNS&utm_medium=parkedpages&utm_campaign=x_corp_tdfs-binns_base&traffic_type=TDFS_BINNS&traffic_id=binns&

I tried to use another add-on to block it, and it does, but the darn site keeps appearing every startup after a fresh boot, and neither Westechnologies not GoDaddy appear anywhere in my Zone Map or anywhere else in my registry. Can anyone help me get rid of it please?

everytime you update firefox, i loose my personal toolbar that took me a long time to set up. how do i get it back without all the work? also, what happened to the printer icon in the main toolbar?

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

I've been having this problem for a couple of weeks now. When I go to certain websites (that work on Every other browser I use) I get the following error:

Network Protocol Error

An error occurred during a connection to www.diamondtoolstore.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

It happens with Lowes & Home Depot - two sites I use every day for work. Now I have to use Chrome or Microsoft Edge -YUCK. I went to your help page and tried everything I could find that may help with this issue and nothing has helped. I see that there are a LOT of other people having the problem as well...Can you please fix it.

I use a public computer that resets itself every night. I want to login to my firefox account so I can receive all my settings, extensions, etc., when I login to sync.

However, when I login to sync, my default search provider remains as Google (the computer's default) and does not change to DuckDuckGo (the settings I previously had synced).

How do I set up sync so that when I login, it pulls all settings, etc., from the cloud, instead of keeping some that were configured locally?

Just pointing out the idiocy of this software... despite having tabs with multiple pages of the same host website open, Muppet-Zilla FireFux starts giving me the old Secure Connection Failed rubbish. Take the link, open it in public of MFF, it opens fine. Even a page that was open fine, try to open a link it, Secure Connection Failed rubbish. Hit the back key, A PAGE THAT WAS OPENED, then Secure Connection Failed rubbish. Yet in CCLeaner, Vivaldi, Chrome, Edge, no issues. So, I guess the message in that is clear - uninstall MFF, never install again. Good to know.

Hello, when initiating a request for conditional mediation with webauthn I get the following error:

TypeError: 'conditional' (value of mediation) is not a valid value for enumeration CredentialMediationRequirement.

However when asking whether it's available with `await window.PublicKeyCredential.isConditionalMediationAvailable()` it does return true. Is this a bug?

i use to have firefox or mozilla on my toolbar, do not know how to question or figure out what i am looking,

is it adding tab firefox or mozilla to the toolbar, when on toolbar you would click on firefox for a new tab.

thank you rodney l gandy sr

I've seen other people ask this question, and the stock answer appears to be: a) They may be different subdomains, but they're the same site. b) Just add an extra bit on the end of each user name so you can get at the correct one.

Unfortunately...

a) No they are most definitely not the same site: myFirstClientsDevSite.mytestdomain.com mySecondClientsDevSite.mytestdomain.com myThirdClientsDevSite.mytestdomain.com myFirstClientsUATSite.mytestdomain.com mySecondClientsUATSite.mytestdomain.com myThirdClientsUATSite.mytestdomain.com

You see the problem? Firefox treats all those sites as being "the same site", even though they patently are not.

b) I'm working with a lot more than three clients. Plus, that suggestion is basically "we admit that our product is broken, here's a work-around that a few people may be able to use".

And finally: I'm pretty sure that Firefox used to be able to discriminate between subdomains, so the question isn't so much "how can I get it to work", as "why was it taken away in the first place".

Hi all,

Using: Firefox 119.0.1 (64-bit) on Windows 10.

I seem to having an issue with adding search shortcuts on FF, I am following this guide:

https://support.mozilla.org/en-US/kb/assign-shortcuts-search-engines

But I'm stuck at step #4 as the table seems to be disabled.

This is a personal laptop and has not policies on it.

Thanks for your time and assistance!
